How to Create an Android App Without Coding

Alternative approaches to Android application development—those that involve writing no code at all or writing only minimal amounts of code—are becoming increasingly feasible today. They are, of course, ideal for non-programmers, but experienced programmers too can use them to save time and effort. In this tutorial, I'm going to talk about two such approaches and introduce you to several tools and templates that enable them.

CodeCanyon is a Marketplace for App Templates and Builders

CodeCanyon is an online marketplace that has hundreds of additional professional Android app templates and builder tools. Some of these are incredibly feature-rich and well-designed. You can sometimes save days, even months, of effort by using one of them.

1. Using App Builders

App builders are usually tools that allow you to create apps by simply filling in a few forms. Most of the popular ones are flexible enough to create a large variety of apps. For instance, you could use them to create e-commerce apps, news apps, or even chat apps. And the best thing about them is that you won't have to write a single line of code while using them.

React App Builder

React App Builder, a premium tool available on CodeCanyon, is perhaps the most powerful and flexible app builder you can get today. Because it uses the React Native cross-platform framework internally, you can use it to create apps for both Android and iOS devices.

It offers a very intuitive, drag and drop interactions-based user interface for building apps. It also comes with 11 beautiful templates you can use to jump-start your app development.

It's worth noting that this tool is also available as a cloud-hosted service. If you don't want to spend any time installing, configuring, and regularly updating the tool on your computer, using the cloud-based option would be ideal for you.

IMABuildeRz

IMABuildeRz is another popular app builder that can build apps for both Android and iOS devices. It uses the Ionic 4 framework internally, so it generates TypeScript and SCSS code.

This tool comes with a large number of addons you can use to quickly add common features to your apps. For example, there are addons to handle forms, JSON documents, JWT authentication, and AdMob ads. There are also addons that can instantly generate full-fledged screens, such as "About Us" and "Contact Us" screens.

Furthermore, there are directives available to implement functionality such as text to speech, barcode scanning, and media streaming.

AppsGeyser: A Free Android App Builder

If you're looking for a tool that's free, AppsGeyser is definitely worth a try. It's an online app development platform that offers over 70 unique app templates and a simple, forms-based interface to customize them. There are templates for quiz apps, coloring apps, browsers, messengers, and several different types of games too.

Note that the free version of AppsGeyser works on a revenue share system. In other words, it expects you to have ads in your apps and share 50% of your revenue. If you're not okay with that, you'll have to switch to the premium version, which allows you to turn the ads off.

2. Converting Websites to Apps

If you already have a blog or a progressive web app, there are tools available on CodeCanyon that can turn it into a native Android app. Most of them use either webviews or the WordPress API to do so.

WebViewGold for Android

WebViewGold for Android is a very popular template for converting websites into high-performance, native Android apps. The apps you build with it will have support for in-app purchases, push notifications, deep links, AdMob ads, and many different kinds of native dialogs. Right out of the box, you also get easily customizable splash screens, loading indicators, and offline screens.

If you're in a hurry and want to create your app within the next couple of minutes, WebViewGold is for you. All you need to do is point the template to your website or a local folder containing all your HTML files and build it with the latest version of Android Studio.

WebViewGold is available for iOS too. So if you want your app to run natively on both Android and iOS, and have a similar look and feel on both platforms, using these templates is the way to go.

Universal Android WebView

The Universal Android WebView template has been a bestseller on CodeCanyon for years now. This Android template can convert any website into a native Material Design app that looks good and performs well on both phones and tablets. Because color is an extremely important aspect of Material Design, it offers ten beautiful color themes for your apps.

The apps you build with this template will have a navigation drawer and support for the pull-to-refresh gesture. They'll also be fully integrated with AdMob ads, Firebase Analytics, and Firebase Cloud Messaging. Additionally, to be able to handle file downloads, they'll have a download manager built into them.

To customize the Universal Android WebView template, you only need to make changes in a single configuration file, which is very easy to understand. As such, if you have a responsive website, you should be able to convert it into a well-polished app in about 15 minutes using this template.

Android App Builder

Android App Builder is another tool that can convert any website into a native Android app. It also offers additional features for WordPress sites. For instance, it has six different layouts for rendering your WordPress posts, with support for the parallax scrolling effect.

If you have a website that doesn't use WordPress, make sure that it has a responsive layout for best results. Apps for such websites would, by default, have handy features such as support for file uploads and downloads, loading indicators, and the swipe-to-refresh gesture built into them.

Android App Builder also has several features dedicated to handling all the YouTube videos, Flickr albums, and Tumblr posts you embed in your websites. It comes with six unique layouts for displaying the contents of YouTube channels and playlists. Similarly, to display the contents of your Flickr albums and Tumblr picture posts, it offers three layouts.

Flink App Builder

Flink App Builder is a powerful tool that helps you convert a WordPress site into a native Android app in just a few clicks. Because it is fully integrated with the WordPress platform, the apps you build with it will be capable of smoothly rendering all your blog's posts, pages, comments, and image galleries. Furthermore, any changes you make on your blog will be instantly reflected in your app.

All the apps you create with Flink will have in-built support for push notifications. And if you want to monetize those apps, you can choose to add AdMob ads or Facebook Audience Network ads to them.

Flink apps have many additional features to improve the user experience they offer, such as screen transition animations, splash screens, and Material Design components. But one of the best things about them, in my opinion, is that they have user management built into them. This means, not only do they support user sign ups and sign ins, they are also capable of having password-protected content.

RocketWeb

RocketWeb is another premium template that uses a webview to turn a web app into a native Android app. It offers over 50 themes you can use to style your app. Some themes have solid colors, while others have attractive gradients.

The template is highly customizable, but there's no coding required. You can use a simple, browser-based form to configure the template so it matches your requirements.

The apps you create with RocketWeb will have, in addition to the webview, a navigation drawer, a toolbar, and a beautiful splash screen, all of which can be tweaked to match your site's look and feel. They'll also have error pages included, which you can use to handle connectivity issues and other such runtime errors.

RocketWeb apps support both Google Cloud Messaging and OneSignal push notifications. And if you wish to monetize them, all you need to do is enable AdMob ads.

Conclusion

You can be a non-programmer and still build profitable Android apps. In this article, I introduced you to several tools and templates you can use to do so. Most of the tools I mentioned are so easy to use and speed up the process of app development so much that you can potentially churn out multiple apps every day. By adding ads to those apps and publishing them on Google Play, you can easily build a new passive income stream for yourself.

If you're only interested in quickly building an attractive app for your business, I suggest you also take a look at some of the full Android application templates available on CodeCanyon. You can learn more about app templates in our other posts.

“Create Once, Publish Everywhere” With WordPress

Leonardo Losoviz

2019-10-28T16:00:59+02:002019-10-28T21:09:38+00:00

COPE is a strategy for reducing the amount of work needed to publish our content into different mediums, such as website, email, apps, and others. First pioneered by NPR, it accomplishes its goal by establishing a single source of truth for content which can be used for all of the different mediums.

Having content that works everywhere is not a trivial task since each medium will have its own requirements. For instance, whereas HTML is valid for printing content for the web, this language is not valid for an iOS/Android app. Similarly, we can add classes to our HTML for the web, but these must be converted to styles for email.

The solution to this conundrum is to separate form from content: The presentation and the meaning of the content must be decoupled, and only the meaning is used as the single source of truth. The presentation can then be added in another layer (specific to the selected medium).

For example, given the following piece of HTML code, the <p> is an HTML tag which applies mostly for the web, and attribute class="align-center" is presentation (placing an element “on the center” makes sense for a screen-based medium, but not for an audio-based one such as Amazon Alexa):

<p class="align-center">Hello world!</p>

Hence, this piece of content cannot be used as a single source of truth, and it must be converted into a format which separates the meaning from the presentation, such as the following piece of JSON code:

{ content: "Hello world!", placement: "center", type: "paragraph" }

This piece of code can be used as a single source of truth for content since from it we can recreate once again the HTML code to use for the web, and procure an appropriate format for other mediums.

Why WordPress

WordPress is ideal to implement the COPE strategy due of several reasons:

It is versatile. The WordPress database model does not define a fixed, rigid content model; on the contrary, it was created for versatility, enabling to create varied content models through the use of meta field, which allow the storing of additional pieces of data for four different entities: posts and custom post types, users, comments, and taxonomies (tags and categories).

It is powerful. WordPress shines as a CMS (Content Management System), and its plugin ecosystem enables to easily add new functionalities.

It is widespread. It is estimated that 1/3rd of websites run on WordPress. Then, a sizable amount of people working on the web know about and are able to use, i.e. WordPress. Not just developers but also bloggers, salesmen, marketing staff, and so on. Then, many different stakeholders, no matter their technical background, will be able to produce the content which acts as the single source of truth.

It is headless. Headlessness is the ability to decouple the content from the presentation layer, and it is a fundamental feature for implementing COPE (as to be able to feed data to dissimilar mediums). Since incorporating the WP REST API into core starting from version 4.7, and more markedly since the launch of Gutenberg in version 5.0 (for which plenty of REST API endpoints had to be implemented), WordPress can be considered a headless CMS, since most WordPress content can be accessed through a REST API by any application built on any stack. In addition, the recently-created WPGraphQL integrates WordPress and GraphQL, enabling to feed content from WordPress into any application using this increasingly popular API. Finally, my own project PoP has recently added an implementation of an API for WordPress which allows to export the WordPress data as either REST, GraphQL or PoP native formats.

It has Gutenberg, a block-based editor that greatly aids the implementation of COPE because it is based on the concept of blocks (as explained in the sections below).

Blobs Versus Blocks To Represent Information

A blob is a single unit of information stored all together in the database. For instance, writing the blog post below on a CMS that relies on blobs to store information will store the blog post content on a single database entry — containing that same content:

<p>Look at this wonderful tango:</p> <figure> <iframe width="951" height="535" src="https://www.youtube.com/embed/sxm3Xyutc1s" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <figcaption>An exquisite tango performance</figcaption> </figure>

As it can be appreciated, the important bits of information from this blog post (such as the content in the paragraph, and the URL, the dimensions and attributes of the Youtube video) are not easily accessible: If we want to retrieve any of them on their own, we need to parse the HTML code to extract them — which is far from an ideal solution.

Blocks act differently. By representing the information as a list of blocks, we can store the content in a more semantic and accessible way. Each block conveys its own content and its own properties which can depend on its type (e.g. is it perhaps a paragraph or a video?).

For example, the HTML code above could be represented as a list of blocks like this:

{ [ type: "paragraph", content: "Look at this wonderful tango:" ], [ type: "embed", provider: "Youtube", url: "https://www.youtube.com/embed/sxm3Xyutc1s", width: 951, height: 535, frameborder: 0, allowfullscreen: true, allow: "accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture", caption: "An exquisite tango performance" ] }

Through this way of representing information, we can easily use any piece of data on its own, and adapt it for the specific medium where it must be displayed. For instance, if we want to extract all the videos from the blog post to show on a car entertainment system, we can simply iterate all blocks of information, select those with type="embed" and provider="Youtube", and extract the URL from them. Similarly, if we want to show the video on an Apple Watch, we need not care about the dimensions of the video, so we can ignore attributes width and height in a straightforward manner.

How Gutenberg Implements Blocks

Before WordPress version 5.0, WordPress used blobs to store post content in the database. Starting from version 5.0, WordPress ships with Gutenberg, a block-based editor, enabling the enhanced way to process content mentioned above, which represents a breakthrough towards the implementation of COPE. Unfortunately, Gutenberg has not been designed for this specific use case, and its representation of the information is different to the one just described for blocks, resulting in several inconveniences that we will need to deal with.

Let’s first have a glimpse on how the blog post described above is saved through Gutenberg:

<p>Look at this wonderful tango:</p>   <figure class="wp-block-embed-youtube wp-block-embed is-type-rich is-provider-embed-handler wp-embed-aspect-16-9 wp-has-aspect-ratio"> <div class="wp-block-embed__wrapper"> https://www.youtube.com/embed/sxm3Xyutc1s </div> <figcaption>An exquisite tango performance</figcaption> </figure>

From this piece of code, we can make the following observations:

Blocks Are Saved All Together In The Same Database Entry

There are two blocks in the code above:

<p>Look at this wonderful tango:</p>

<figure class="wp-block-embed-youtube wp-block-embed is-type-rich is-provider-embed-handler wp-embed-aspect-16-9 wp-has-aspect-ratio"> <div class="wp-block-embed__wrapper"> https://www.youtube.com/embed/sxm3Xyutc1s </div> <figcaption>An exquisite tango performance</figcaption> </figure>

With the exception of global (also called “reusable”) blocks, which have an entry of their own in the database and can be referenced directly through their IDs, all blocks are saved together in the blog post’s entry in table wp_posts.

Hence, to retrieve the information for a specific block, we will first need to parse the content and isolate all blocks from each other. Conveniently, WordPress provides function parse_blocks($content) to do just this. This function receives a string containing the blog post content (in HTML format), and returns a JSON object containing the data for all contained blocks.

Block Type And Attributes Are Conveyed Through HTML Comments

Each block is delimited with a starting tag  and an ending tag  which (being HTML comments) ensure that this information will not be visible when displaying it on a website. However, we can’t display the blog post directly on another medium, since the HTML comment may be visible, appearing as garbled content. This is not a big deal though, since after parsing the content through function parse_blocks($content), the HTML comments are removed and we can operate directly with the block data as a JSON object.

Blocks Contain HTML

The paragraph block has "<p>Look at this wonderful tango:</p>" as its content, instead of "Look at this wonderful tango:". Hence, it contains HTML code (tags <p> and </p>) which is not useful for other mediums, and as such must be removed, for instance through PHP function strip_tags($content).

When stripping tags, we can keep those HTML tags which explicitly convey semantic information, such as tags <strong> and <em> (instead of their counterparts <b> and <i> which apply only to a screen-based medium), and remove all other tags. This is because there is a great chance that semantic tags can be properly interpreted for other mediums too (e.g. Amazon Alexa can recognize tags <strong> and <em>, and change its voice and intonation accordingly when reading a piece of text). To do this, we invoke the strip_tags function with a 2nd parameter containing the allowed tags, and place it within a wrapping function for convenience:

function strip_html_tags($content) { return strip_tags($content, '<strong><em>'); }

The Video’s Caption Is Saved Within The HTML And Not As An Attribute

As can be seen in the Youtube video block, the caption "An exquisite tango performance" is stored inside the HTML code (enclosed by tag <figcaption />) but not inside the JSON-encoded attributes object. As a consequence, to extract the caption, we will need to parse the block content, for instance through a regular expression:

function extract_caption($content) { $matches = []; preg_match('/<figcaption>(.*?)<\/figcaption>/', $content, $matches); if ($caption = $matches[1]) { return strip_html_tags($caption); } return null; }

This is a hurdle we must overcome in order to extract all metadata from a Gutenberg block. This happens on several blocks; since not all pieces of metadata are saved as attributes, we must then first identify which are these pieces of metadata, and then parse the HTML content to extract them on a block-by-block and piece-by-piece basis.

Concerning COPE, this represents a wasted chance to have a really optimal solution. It could be argued that the alternative option is not ideal either, since it would duplicate information, storing it both within the HTML and as an attribute, which violates the DRY (Don’t Repeat Yourself) principle. However, this violation does already take place: For instance, attribute className contains value "wp-embed-aspect-16-9 wp-has-aspect-ratio", which is printed inside the content too, under HTML attribute class.

Adding content through Gutenberg (Large preview)

Implementing COPE

Note: I have released this functionality, including all the code described below, as WordPress plugin Block Metadata. You’re welcome to install it and play with it so you can get a taste of the power of COPE. The source code is available in this GitHub repo.

Now that we know what the inner representation of a block looks like, let’s proceed to implement COPE through Gutenberg. The procedure will involve the following steps:

Because function parse_blocks($content) returns a JSON object with nested levels, we must first simplify this structure.

We iterate all blocks and, for each, identify their pieces of metadata and extract them, transforming them into a medium-agnostic format in the process. Which attributes are added to the response can vary depending on the block type.

We finally make the data available through an API (REST/GraphQL/PoP).

Let’s implement these steps one by one.

1. Simplifying The Structure Of The JSON Object

The returned JSON object from function parse_blocks($content) has a nested architecture, in which the data for normal blocks appear at the first level, but the data for a referenced reusable block are missing (only data for the referencing block are added), and the data for nested blocks (which are added within other blocks) and for grouped blocks (where several blocks can be grouped together) appear under 1 or more sublevels. This architecture makes it difficult to process the block data from all blocks in the post content, since on one side some data are missing, and on the other we don’t know a priori under how many levels data are located. In addition, there is a block divider placed every pair of blocks, containing no content, which can be safely ignored.

For instance, the response obtained from a post containing a simple block, a global block, a nested block containing a simple block, and a group of simple blocks, in that order, is the following:

[ // Simple block { "blockName": "core/image", "attrs": { "id": 70, "sizeSlug": "large" }, "innerBlocks": [], "innerHTML": "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/sandwich-1024x614.jpg\" alt=\"\" class=\"wp-image-70\"/><figcaption>This is a normal block</figcaption></figure>\n", "innerContent": [ "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/sandwich-1024x614.jpg\" alt=\"\" class=\"wp-image-70\"/><figcaption>This is a normal block</figcaption></figure>\n" ] }, // Empty block divider { "blockName": null, "attrs": [], "innerBlocks": [], "innerHTML": "\n\n", "innerContent": [ "\n\n" ] }, // Reference to reusable block { "blockName": "core/block", "attrs": { "ref": 218 }, "innerBlocks": [], "innerHTML": "", "innerContent": [] }, // Empty block divider { "blockName": null, "attrs": [], "innerBlocks": [], "innerHTML": "\n\n", "innerContent": [ "\n\n" ] }, // Nested block { "blockName": "core/columns", "attrs": [], // Contained nested blocks "innerBlocks": [ { "blockName": "core/column", "attrs": [], // Contained nested blocks "innerBlocks": [ { "blockName": "core/image", "attrs": { "id": 69, "sizeSlug": "large" }, "innerBlocks": [], "innerHTML": "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/espresso-1024x614.jpg\" alt=\"\" class=\"wp-image-69\"/></figure>\n", "innerContent": [ "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/espresso-1024x614.jpg\" alt=\"\" class=\"wp-image-69\"/></figure>\n" ] } ], "innerHTML": "\n<div class=\"wp-block-column\"></div>\n", "innerContent": [ "\n<div class=\"wp-block-column\">", null, "</div>\n" ] }, { "blockName": "core/column", "attrs": [], // Contained nested blocks "innerBlocks": [ { "blockName": "core/paragraph", "attrs": [], "innerBlocks": [], "innerHTML": "\n<p>This is how I wake up every morning</p>\n", "innerContent": [ "\n<p>This is how I wake up every morning</p>\n" ] } ], "innerHTML": "\n<div class=\"wp-block-column\"></div>\n", "innerContent": [ "\n<div class=\"wp-block-column\">", null, "</div>\n" ] } ], "innerHTML": "\n<div class=\"wp-block-columns\">\n\n</div>\n", "innerContent": [ "\n<div class=\"wp-block-columns\">", null, "\n\n", null, "</div>\n" ] }, // Empty block divider { "blockName": null, "attrs": [], "innerBlocks": [], "innerHTML": "\n\n", "innerContent": [ "\n\n" ] }, // Block group { "blockName": "core/group", "attrs": [], // Contained grouped blocks "innerBlocks": [ { "blockName": "core/image", "attrs": { "id": 71, "sizeSlug": "large" }, "innerBlocks": [], "innerHTML": "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/coffee-1024x614.jpg\" alt=\"\" class=\"wp-image-71\"/><figcaption>First element of the group</figcaption></figure>\n", "innerContent": [ "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/coffee-1024x614.jpg\" alt=\"\" class=\"wp-image-71\"/><figcaption>First element of the group</figcaption></figure>\n" ] }, { "blockName": "core/paragraph", "attrs": [], "innerBlocks": [], "innerHTML": "\n<p>Second element of the group</p>\n", "innerContent": [ "\n<p>Second element of the group</p>\n" ] } ], "innerHTML": "\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container\">\n\n</div></div>\n", "innerContent": [ "\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container\">", null, "\n\n", null, "</div></div>\n" ] } ]

A better solution is to have all data at the first level, so the logic to iterate through all block data is greatly simplified. Hence, we must fetch the data for these reusable/nested/grouped blocks, and have it added on the first level too. As it can be seen in the JSON code above:

The empty divider block has attribute "blockName" with value NULL

The reference to a reusable block is defined through $block["attrs"]["ref"]

Nested and group blocks define their contained blocks under $block["innerBlocks"]

Hence, the following PHP code removes the empty divider blocks, identifies the reusable/nested/grouped blocks and adds their data to the first level, and removes all data from all sublevels:

/** * Export all (Gutenberg) blocks' data from a WordPress post */ function get_block_data($content, $remove_divider_block = true) { // Parse the blocks, and convert them into a single-level array $ret = []; $blocks = parse_blocks($content); recursively_add_blocks($ret, $blocks); // Maybe remove blocks without name if ($remove_divider_block) { $ret = remove_blocks_without_name($ret); } // Remove 'innerBlocks' property if it exists (since that code was copied to the first level, it is currently duplicated) foreach ($ret as &$block) { unset($block['innerBlocks']); } return $ret; } /** * Remove the blocks without name, such as the empty block divider */ function remove_blocks_without_name($blocks) { return array_values(array_filter( $blocks, function($block) { return $block['blockName']; } )); } /** * Add block data (including global and nested blocks) into the first level of the array */ function recursively_add_blocks(&$ret, $blocks) { foreach ($blocks as $block) { // Global block: add the referenced block instead of this one if ($block['attrs']['ref']) { $ret = array_merge( $ret, recursively_render_block_core_block($block['attrs']) ); } // Normal block: add it directly else { $ret[] = $block; } // If it contains nested or grouped blocks, add them too if ($block['innerBlocks']) { recursively_add_blocks($ret, $block['innerBlocks']); } } } /** * Function based on `render_block_core_block` */ function recursively_render_block_core_block($attributes) { if (empty($attributes['ref'])) { return []; } $reusable_block = get_post($attributes['ref']); if (!$reusable_block || 'wp_block' !== $reusable_block->post_type) { return []; } if ('publish' !== $reusable_block->post_status || ! empty($reusable_block->post_password)) { return []; } return get_block_data($reusable_block->post_content); }

Calling function get_block_data($content) passing the post content ($post->post_content) as parameter, we now obtain the following response:

[[ { "blockName": "core/image", "attrs": { "id": 70, "sizeSlug": "large" }, "innerHTML": "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/sandwich-1024x614.jpg\" alt=\"\" class=\"wp-image-70\"/><figcaption>This is a normal block</figcaption></figure>\n", "innerContent": [ "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/sandwich-1024x614.jpg\" alt=\"\" class=\"wp-image-70\"/><figcaption>This is a normal block</figcaption></figure>\n" ] }, { "blockName": "core/paragraph", "attrs": [], "innerHTML": "\n<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>\n", "innerContent": [ "\n<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>\n" ] }, { "blockName": "core/columns", "attrs": [], "innerHTML": "\n<div class=\"wp-block-columns\">\n\n</div>\n", "innerContent": [ "\n<div class=\"wp-block-columns\">", null, "\n\n", null, "</div>\n" ] }, { "blockName": "core/column", "attrs": [], "innerHTML": "\n<div class=\"wp-block-column\"></div>\n", "innerContent": [ "\n<div class=\"wp-block-column\">", null, "</div>\n" ] }, { "blockName": "core/image", "attrs": { "id": 69, "sizeSlug": "large" }, "innerHTML": "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/espresso-1024x614.jpg\" alt=\"\" class=\"wp-image-69\"/></figure>\n", "innerContent": [ "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/espresso-1024x614.jpg\" alt=\"\" class=\"wp-image-69\"/></figure>\n" ] }, { "blockName": "core/column", "attrs": [], "innerHTML": "\n<div class=\"wp-block-column\"></div>\n", "innerContent": [ "\n<div class=\"wp-block-column\">", null, "</div>\n" ] }, { "blockName": "core/paragraph", "attrs": [], "innerHTML": "\n<p>This is how I wake up every morning</p>\n", "innerContent": [ "\n<p>This is how I wake up every morning</p>\n" ] }, { "blockName": "core/group", "attrs": [], "innerHTML": "\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container\">\n\n</div></div>\n", "innerContent": [ "\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container\">", null, "\n\n", null, "</div></div>\n" ] }, { "blockName": "core/image", "attrs": { "id": 71, "sizeSlug": "large" }, "innerHTML": "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/coffee-1024x614.jpg\" alt=\"\" class=\"wp-image-71\"/><figcaption>First element of the group</figcaption></figure>\n", "innerContent": [ "\n<figure class=\"wp-block-image size-large\"><img src=\"http://localhost/wp-content/uploads/2017/12/coffee-1024x614.jpg\" alt=\"\" class=\"wp-image-71\"/><figcaption>First element of the group</figcaption></figure>\n" ] }, { "blockName": "core/paragraph", "attrs": [], "innerHTML": "\n<p>Second element of the group</p>\n", "innerContent": [ "\n<p>Second element of the group</p>\n" ] } ]

Even though not strictly necessary, it is very helpful to create a REST API endpoint to output the result of our new function get_block_data($content), which will allow us to easily understand what blocks are contained in a specific post, and how they are structured. The code below adds such endpoint under /wp-json/block-metadata/v1/data/{POST_ID}:

/** * Define REST endpoint to visualize a post’s block data */ add_action('rest_api_init', function () { register_rest_route('block-metadata/v1', 'data/(?P\d+)', [ 'methods' => 'GET', 'callback' => 'get_post_blocks' ]); }); function get_post_blocks($request) { $post = get_post($request['post_id']); if (!$post) { return new WP_Error('empty_post', 'There is no post with this ID', array('status' => 404)); } $block_data = get_block_data($post->post_content); $response = new WP_REST_Response($block_data); $response->set_status(200); return $response; }

To see it in action, check out this link which exports the data for this post.

2. Extracting All Block Metadata Into A Medium-Agnostic Format

At this stage, we have block data containing HTML code which is not appropriate for COPE. Hence, we must strip the non-semantic HTML tags for each block as to convert it into a medium-agnostic format.

We can decide which are the attributes that must be extracted on a block type by block type basis (for instance, extract the text alignment property for "paragraph" blocks, the video URL property for the "youtube embed" block, and so on).

As we saw earlier on, not all attributes are actually saved as block attributes but within the block’s inner content, hence, for these situations, we will need to parse the HTML content using regular expressions in order to extract those pieces of metadata.

After inspecting all blocks shipped through WordPress core, I decided not to extract metadata for the following ones:

"core/columns" "core/column" "core/cover" These apply only to screen-based mediums and (being nested blocks) are difficult to deal with. "core/html" This one only makes sense for web. "core/table" "core/button" "core/media-text" I had no clue how to represent their data on a medium-agnostic fashion or if it even makes sense.

This leaves me with the following blocks, for which I’ll proceed to extract their metadata:

'core/paragraph'

'core/image'

'core-embed/youtube' (as a representative of all the 'core-embed' blocks)

'core/heading'

'core/gallery'

'core/list'

'core/audio'

'core/file'

'core/video'

'core/code'

'core/preformatted'

'core/quote' & 'core/pullquote'

'core/verse'

To extract the metadata, we create function get_block_metadata($block_data) which receives an array with the block data for each block (i.e. the output from our previously-implemented function get_block_data) and, depending on the block type (provided under property "blockName"), decides what attributes are required and how to extract them:

/** * Process all (Gutenberg) blocks' metadata into a medium-agnostic format from a WordPress post */ function get_block_metadata($block_data) { $ret = []; foreach ($block_data as $block) { $blockMeta = null; switch ($block['blockName']) { case ...: $blockMeta = ... break; case ...: $blockMeta = ... break; ... } if ($blockMeta) { $ret[] = [ 'blockName' => $block['blockName'], 'meta' => $blockMeta, ]; } } return $ret; }

Let’s proceed to extract the metadata for each block type, one by one:

"core/paragraph"

Simply remove the HTML tags from the content, and remove the trailing breaklines.

case 'core/paragraph': $blockMeta = [ 'content' => trim(strip_html_tags($block['innerHTML'])), ]; break;

'core/image'

The block either has an ID referring to an uploaded media file or, if not, the image source must be extracted from under <img src="...">. Several attributes (caption, linkDestination, link, alignment) are optional.

case 'core/image': $blockMeta = []; // If inserting the image from the Media Manager, it has an ID if ($block['attrs']['id'] && $img = wp_get_attachment_image_src($block['attrs']['id'], $block['attrs']['sizeSlug'])) { $blockMeta['img'] = [ 'src' => $img[0], 'width' => $img[1], 'height' => $img[2], ]; } elseif ($src = extract_image_src($block['innerHTML'])) { $blockMeta['src'] = $src; } if ($caption = extract_caption($block['innerHTML'])) { $blockMeta['caption'] = $caption; } if ($linkDestination = $block['attrs']['linkDestination']) { $blockMeta['linkDestination'] = $linkDestination; if ($link = extract_link($block['innerHTML'])) { $blockMeta['link'] = $link; } } if ($align = $block['attrs']['align']) { $blockMeta['align'] = $align; } break;

It makes sense to create functions extract_image_src, extract_caption and extract_link since their regular expressions will be used time and again for several blocks. Please notice that a caption in Gutenberg can contain links (<a href="...">), however, when calling strip_html_tags, these are removed from the caption.

Even though regrettable, I find this practice unavoidable, since we can’t guarantee a link to work in non-web platforms. Hence, even though the content is gaining universality since it can be used for different mediums, it is also losing specificity, so its quality is poorer compared to content that was created and customized for the particular platform.

'core-embed/youtube'

Simply retrieve the video URL from the block attributes, and extract its caption from the HTML content, if it exists.

case 'core-embed/youtube': $blockMeta = [ 'url' => $block['attrs']['url'], ]; if ($caption = extract_caption($block['innerHTML'])) { $blockMeta['caption'] = $caption; } break;

'core/heading'

Both the header size (h1, h2, …, h6) and the heading text are not attributes, so these must be obtained from the HTML content. Please notice that, instead of returning the HTML tag for the header, the size attribute is simply an equivalent representation, which is more agnostic and makes better sense for non-web platforms.

case 'core/heading': $matches = []; preg_match('/<h[1-6])>(.*?)<\/h([1-6])>/', $block['innerHTML'], $matches); $sizes = [ null, 'xxl', 'xl', 'l', 'm', 'sm', 'xs', ]; $blockMeta = [ 'size' => $sizes[$matches[1]], 'heading' => $matches[2], ]; break;

'core/gallery'

Unfortunately, for the image gallery I have been unable to extract the captions from each image, since these are not attributes, and extracting them through a simple regular expression can fail: If there is a caption for the first and third elements, but none for the second one, then I wouldn’t know which caption corresponds to which image (and I haven’t devoted the time to create a complex regex). Likewise, in the logic below I’m always retrieving the "full" image size, however, this doesn’t have to be the case, and I’m unaware of how the more appropriate size can be inferred.

case 'core/gallery': $imgs = []; foreach ($block['attrs']['ids'] as $img_id) { $img = wp_get_attachment_image_src($img_id, 'full'); $imgs[] = [ 'src' => $img[0], 'width' => $img[1], 'height' => $img[2], ]; } $blockMeta = [ 'imgs' => $imgs, ]; break;

'core/list'

Simply transform the <li> elements into an array of items.

case 'core/list': $matches = []; preg_match_all('/<li>(.*?)<\/li>/', $block['innerHTML'], $matches); if ($items = $matches[1]) { $blockMeta = [ 'items' => array_map('strip_html_tags', $items), ]; } break;

'core/audio'

Obtain the URL of the corresponding uploaded media file.

case 'core/audio': $blockMeta = [ 'src' => wp_get_attachment_url($block['attrs']['id']), ]; break;

'core/file'

Whereas the URL of the file is an attribute, its text must be extracted from the inner content.

case 'core/file': $href = $block['attrs']['href']; $matches = []; preg_match('/<a href="'.str_replace('/', '\/', $href).'">(.*?)<\/a>/', $block['innerHTML'], $matches); $blockMeta = [ 'href' => $href, 'text' => strip_html_tags($matches[1]), ]; break;

'core/video'

Obtain the video URL and all properties to configure how the video is played through a regular expression. If Gutenberg ever changes the order in which these properties are printed in the code, then this regex will stop working, evidencing one of the problems of not adding metadata directly through the block attributes.

case 'core/video': $matches = []; preg_match('/

<\/video>>', $block['innerHTML'], $matches); $blockMeta = [ 'src' => $matches[7], ]; if ($poster = $matches[6]) { $blockMeta['poster'] = $poster; } // Video settings $settings = []; if ($matches[1]) { $settings[] = 'autoplay'; } if ($matches[2]) { $settings[] = 'controls'; } if ($matches[3]) { $settings[] = 'loop'; } if ($matches[4]) { $settings[] = 'muted'; } if ($matches[8]) { $settings[] = 'playsinline'; } if ($settings) { $blockMeta['settings'] = $settings; } if ($caption = extract_caption($block['innerHTML'])) { $blockMeta['caption'] = $caption; } break;

'core/code'

Simply extract the code from within <code />.

case 'core/code': $matches = []; preg_match('/<code>(.*?)<\/code>/is', $block['innerHTML'], $matches); $blockMeta = [ 'code' => $matches[1], ]; break;

'core/preformatted'

Similar to <code />, but we must watch out that Gutenberg hardcodes a class too.

case 'core/preformatted': $matches = []; preg_match('/<pre class="wp-block-preformatted">(.*?)<\/pre>/is', $block['innerHTML'], $matches); $blockMeta = [ 'text' => strip_html_tags($matches[1]), ]; break;

'core/quote' and 'core/pullquote'

We must convert all inner <p /> tags to their equivalent generic "\n" character.

case 'core/quote': case 'core/pullquote': $matches = []; $regexes = [ 'core/quote' => '/<blockquote class=\"wp-block-quote\">(.*?)<\/blockquote>/', 'core/pullquote' => '/<figure class=\"wp-block-pullquote\"><blockquote>(.*?)<\/blockquote><\/figure>/', ]; preg_match($regexes[$block['blockName']], $block['innerHTML'], $matches); if ($quoteHTML = $matches[1]) { preg_match_all('/<p>(.*?)<\/p>/', $quoteHTML, $matches); $blockMeta = [ 'quote' => strip_html_tags(implode('\n', $matches[1])), ]; preg_match('/<cite>(.*?)<\/cite>/', $quoteHTML, $matches); if ($cite = $matches[1]) { $blockMeta['cite'] = strip_html_tags($cite); } } break;

'core/verse'

Similar situation to <pre />.

case 'core/verse': $matches = []; preg_match('/<pre class="wp-block-verse">(.*?)<\/pre>/is', $block['innerHTML'], $matches); $blockMeta = [ 'text' => strip_html_tags($matches[1]), ]; break;

3. Exporting Data Through An API

Now that we have extracted all block metadata, we need to make it available to our different mediums, through an API. WordPress has access to the following APIs:

REST, through the WP REST API (integrated in WordPress core)

GraphQL, through WPGraphQL

PoP, through its implementation for WordPress

Let’s see how to export the data through each of them.

REST

The following code creates endpoint /wp-json/block-metadata/v1/metadata/{POST_ID} which exports all block metadata for a specific post:

/** * Define REST endpoints to export the blocks' metadata for a specific post */ add_action('rest_api_init', function () { register_rest_route('block-metadata/v1', 'metadata/(?P\d+)', [ 'methods' => 'GET', 'callback' => 'get_post_block_meta' ]); }); function get_post_block_meta($request) { $post = get_post($request['post_id']); if (!$post) { return new WP_Error('empty_post', 'There is no post with this ID', array('status' => 404)); } $block_data = get_block_data($post->post_content); $block_metadata = get_block_metadata($block_data); $response = new WP_REST_Response($block_metadata); $response->set_status(200); return $response; }

To see it working, this link (corresponding to this blog post) displays the metadata for blocks of all the types analyzed earlier on.

GraphQL (Through WPGraphQL)

GraphQL works by setting-up schemas and types which define the structure of the content, from which arises this API’s power to fetch exactly the required data and nothing else. Setting-up schemas works very well when the structure of the object has a unique representation.

In our case, however, the metadata returned by a new field "block_metadata" (which calls our newly-created function get_block_metadata) depends on the specific block type, so the structure of the response can vary wildly; GraphQL provides a solution to this issue through a Union type, allowing to return one among a set of different types. However, its implementation for all different variations of the metadata structure has proved to be a lot of work, and I quit along the way 😢.

As an alternative (not ideal) solution, I decided to provide the response by simply encoding the JSON object through a new field "jsonencoded_block_metadata":

/** * Define WPGraphQL field "jsonencoded_block_metadata" */ add_action('graphql_register_types', function() { register_graphql_field( 'Post', 'jsonencoded_block_metadata', [ 'type' => 'String', 'description' => __('Post blocks encoded as JSON', 'wp-graphql'), 'resolve' => function($post) { $post = get_post($post->ID); $block_data = get_block_data($post->post_content); $block_metadata = get_block_metadata($block_data); return json_encode($block_metadata); } ] ); });

PoP

Note: This functionality is available on its own GitHub repo.

The final API is called PoP, which is a little-known project I’ve been working on for several years now. I have recently converted it into a full-fledged API, with the capacity to produce a response compatible with both REST and GraphQL, and which even benefits from the advantages from these 2 APIs, at the same time: no under/over-fetching of data, like in GraphQL, while being cacheable on the server-side and not susceptible to DoS attacks, like REST. It offers a mix between the two of them: REST-like endpoints with GraphQL-like queries.

The block metadata is made available through the API through the following code:

class PostFieldValueResolver extends AbstractDBDataFieldValueResolver { public static function getClassesToAttachTo(): array { return array(\PoP\Posts\FieldResolver::class); } public function resolveValue(FieldResolverInterface $fieldResolver, $resultItem, string $fieldName, array $fieldArgs = []) { $post = $resultItem; switch ($fieldName) { case 'block-metadata': $block_data = \Leoloso\BlockMetadata\Data::get_block_data($post->post_content); $block_metadata = \Leoloso\BlockMetadata\Metadata::get_block_metadata($block_data); // Filter by blockName if ($blockName = $fieldArgs['blockname']) { $block_metadata = array_filter( $block_metadata, function($block) use($blockName) { return $block['blockName'] == $blockName; } ); } return $block_metadata; } return parent::resolveValue($fieldResolver, $resultItem, $fieldName, $fieldArgs); } }

To see it in action, this link displays the block metadata (+ ID, title and URL of the post, and the ID and name of its author, à la GraphQL) for a list of posts.

In addition, similar to GraphQL arguments, our query can be customized through field arguments, enabling to obtain only the data that makes sense for a specific platform. For instance, if we desire to extract all Youtube videos added to all posts, we can add modifier (blockname:core-embed/youtube) to field block-metadata in the endpoint URL, like in this link. Or if we want to extract all images from a specific post, we can add modifier (blockname:core/image) like in this other link|id|title).

Conclusion

The COPE (“Create Once, Publish Everywhere”) strategy helps us lower the amount of work needed to create several applications which must run on different mediums (web, email, apps, home assistants, virtual reality, etc) by creating a single source of truth for our content. Concerning WordPress, even though it has always shined as a Content Management System, implementing the COPE strategy has historically proved to be a challenge.

However, a couple of recent developments have made it increasingly feasible to implement this strategy for WordPress. On one side, since the integration into core of the WP REST API, and more markedly since the launch of Gutenberg, most WordPress content is accessible through APIs, making it a genuine headless system. On the other side, Gutenberg (which is the new default content editor) is block-based, making all metadata inside a blog post readily accessible to the APIs.

As a consequence, implementing COPE for WordPress is straightforward. In this article, we have seen how to do it, and all the relevant code has been made available through several repositories. Even though the solution is not optimal (since it involves plenty of parsing HTML code), it still works fairly well, with the consequence that the effort needed to release our applications to multiple platforms can be greatly reduced. Kudos to that!

Latest WordPress trends to follow in 2019

Almost 75 Million websites on the internet work on WordPress. Starting from a simple blog to the largest E-commerce website. WordPress has covered each and everything. The CMS is easy to install and use. Also, there are tons of available plugins and themes that you either download for free or pay a little money to download those. Along with these, if you don’t want to do all the things yourself there are various WordPress Development services available that you can take help of.

Talking about the trends, let’s see what else will be in trend in the upcoming year 2019

1. Chabot’s

Design Systems have become a key part of any company’s everyday work. From discussions to creations, it seems that it has become an integral part of designers’ life. It is believed that in the future, every brand and every product will use a Design System, simple or comprehensive, strict or loose, mono, or cross platforms. Here we are today with our top 10 design system count down. Ready for a fun ride so let the countdown begin.

1.Material Design by Google

Material design system by Google

A modern design language developed by Google in 2014, Material Design aims to create a visual language for users that brings efficiency and modern together created by the innovation of technology. It helps to unify user experiences across all devices and platforms. It is an open-source code, a beautiful collab between designers and developers. It includes many sections including, motion, style, layout, color palette, typography guidelines, icon design, even the ability to create dark material themes, and more.

The first version of Material Design had one drawback that was important for brands that want to adapt it to their style. All Material Design applications were extremely similar. So in 2018 Google launches Material Design 2.0. This version was an answer to the above criticism. With multiple styles, layouts, depth effects, cool animations, they are empowered to make truly unique branding themes.

Users of the system have the tools and resources needed to create a unified UI.

By creating a system that not only acknowledges but also leverages Uber’s evolution into a platform, with a robust, consistent set of basic elements while enabling them to freely explore. This system should be able to welcome incoming innovations without disrupting the existing experiences that feel familiar to so many users.

The ultimate goal of their design platform is to make every designer a little better at thinking of everything in terms of systems — grids, typography, language, motion, accessibility, and so on. This allows everyone to design together, to learn from a common source, and to have a shared understanding of product quality across the company.

Marvel design system by Marvel

Developers don’t want to repeat the same work on different mediums. Companies want to be more efficient. Product designers and owners want the products they work on to be faster, more accessible whilst still looking sharp and consistent. They have also developed a few static sites: A marketing website, a WordPress blog, a bunch of isolated back-end templates.

They have a bunch of design values for colors, typography, layout, and more, structured in a simple JSON format. From there, it is sent to a few places. On one hand, they have a swift style guide generator which generates the design values consumed by iOS and Mac apps. On the other, there is a simple atomic CSS framework, which then gets consumed by anything that uses web technology; be that React, PHP, or old school email table templates.

It not only offers affordable hospitality services around the globe. The company also shares insights about their featuring cutting edge techniques.

In the process of building the system, Airbnb also integrated internal and third-party tools. For example, the React-sketch app which is an open-source library that lets you write React components that render to Sketch documents.

With this design system in place, Airbnb is able to speed up development. Engineers are able to focus on writing the feature logic rather than the view code, and it enables faster prototyping and experimenting at a lower cost.

These were the top 10 must-know design systems. I hope you enjoyed the countdown. Don’t forget to check Iconscout to discover millions of icons, illustrations, and stock photos which you can use in developing your Design system.

What is a progressive web app (PWA)? Why would you want one?

Edwin Toonen

Edwin is a strategic content specialist. Before joining Yoast, he spent years honing his skill at The Netherlands’ leading web design magazine.

It’s been years since the beginning of the age of the smartphone. With it came the era of native apps. Apps continue to play a massive role in our daily life, and many business owners have asked themselves multiple times: should we have an app? Of course, the only answer to that is — it depends. Building and maintaining a native app is cumbersome and often quite expensive. Luckily, there is another option. This option combines the joys of a native app with the technology we use on the web: the progressive web app, a.k.a. PWA.

What is a PWA?

Twitter.com is a PWA

PWA stands for progressive web app. This is an app built from the web technologies we all know and love, like HTML, CSS, and JavaScript, but with a feel and functionality that rivals an actual native app. Thanks to a couple of smart additions, you can turn almost any website into a progressive web app. This means that you can build a PWA rather quickly, in regards to a native app that’s pretty difficult to develop. Plus, you can offer all the features of native apps, like push notifications, offline support, and much more.

Many sites you find online are actually a progressive web app. Take twitter.com, for instance. If you visit that site on your smartphone, you can install it to your home screen. Now, on opening the saved Twitter site, you’ll notice that it looks and performs just like a native app. There’s no browser window or nothing. There’s no difference in running it from an iPhone or an Android smartphone. Simply log in and you’re good to go. That’s a major benefit of building your web app with a PWA in mind.

PWAs are gaining popularity. Many big sites are PWAs, like Starbucks.com, Pinterest.com, Washingtonpost.com and Uber.com are actually installable on your home screen and offer a comparable experience to their native apps.

What’s the difference between a native app and a PWA?

A native app, like the ones you download from Apple’s App Store or Google’s Play Store, is often built in a programming language specific to that platform. So for iOS apps, that would be Swift and for Android apps, Java. If you want to build an app for those platforms, you need to know the technology. Yes, there are shortcuts, but these come with their own limitations. If you want to have an app on all the mobile platforms, you need to know all the different technologies. There’s no easy way to build one and publish it to all the stores out there.

Of course, there are ways to get the best of both worlds. A progressive web app, for instance. This runs in the browser and — once saved to the home screen — functions like a native app. It even gets access to the underlying hardware and software that the browser can’t access for safety reasons. If the PWA performs great, users will never know that they are using a web-based app instead of a native one.

There are some caveats, of course. While browsers have been quick to adopt the technology for this, there are still some limitations. On iOS, the technology needed works spotty in Safari. Apple doesn’t (want to) support everything yet, making it a bit of a chore to get the same exact experience everywhere.

What are the benefits of a PWA?

The main reason why everyone is chasing after apps is because they offer greater engagement. Users who install your app are your biggest fans and they are more likely to turn their usage into sales or signups. Thanks to push notifications it’s much easier to re-engage with users. Apps can offer an excellent experience that can do well for a brand.

We talked about some of the plusses of PWAs in this article, but here’s a short overview:

You don’t have to go through the process to get into different app stores

You can build PWAs with common web technologies

They are often cheaper to build

Since you’re turning your site into an app, you’ll have fewer code-bases to maintain

PWAs are responsive and work with many different screen sizes

PWAs are smooth, fast and lightweight

No need to hand off big chunks of money to Google and Apple

They work offline, unlike your regular site

PWAs are discoverable via search engines (which have a lot larger audience than app stores. Plus, if you want you can still get your PWAs distributed via app stores)

You can use push notifications to re-engage users

Installing a PWA can lead to higher engagement

Still, native apps win out sometimes. PWAs get deeper and deeper access to the operating system of a smartphone, but a native app can go deeper still. Plus, there are limits to what a PWA can do. For instance, PWAs are not the best choice when you want to build high-performance games.

All in all, it makes a lot of sense to think about having a PWA in your mobile strategy. But, the main question you should ask yourself is: does my audience want this?

Who’s this for?

Should everyone simply build a PWA and be done with it? No, consider your business and — more importantly — your target audience. Are they even using apps? Isn’t this an overly complex way of getting to what you want to achieve? Again, like everything, you need to research the needs of your audience. Ask yourself, what do you want this technology to do? Where are your users? Do they have a good data connection and solid hardware? How and where are they using your content? And do you think an app can help them do their job better?

PWAs are awesome and implementing them doesn’t have to be all that hard. But just because it’s easy doesn’t mean you should do it. If your audience has no need for it, why would you build one?

What are the SEO concerns of a PWA?

The PWA is inherently web-centric. It was born from the web and developed with search engines in mind to make discovery easy. Of course, you can make a progressive web app out of any-old site and it doesn’t take much to do so. However, many PWAs use JavaScript to build more complex functionality and while search engines have become apt at rendering JavaScript, it can still be a cause for concern.

When setting up a PWA, you have to make sure your JavaScript is accessible. Don’t block files for bots and make sure that links are available. To improve the rendering process you can make your JavaScript framework use server-side rendering.

Turning your site into a PWA doesn’t mean you directly improve the SEO Company of that site. If it makes sense to turn your site into a PWA, do so, but don’t do it for any perceived SEO Company benefits. If you have a great PWA, you are offering your users a fantastic user experience, which might make you one-up your competition. In this regard, it’s a good idea to take a look at them for your mobile SEO strategy.

What are the three main building blocks?

It doesn’t take much to set up a PWA. There are three things you need to provide before your site turns into a valid PWA.

A secure connection (HTTPS): PWAs only work on trusted connections, you have to serve them over a secure connection. This is not only for security reasons, but it’s also a very important trust factor for users.

A service worker: A service worker is a piece of script that runs in the background. This helps you determine how to handle network requests for your PWA, making it possible to do more complex work.

The manifest file: This JSON file contains information on how your PWA should appear and function. Here, you determine the name, description, icons, colors, et cetera.

Here’s a sample manifest from Google:

{ "short_name": "Weather", "name": "Weather: Do I need an umbrella?", "description": "Weather forecast information", "icons": [ { "src": "/images/icons-192.png", "type": "image/png", "sizes": "192x192" }, { "src": "/images/icons-512.png", "type": "image/png", "sizes": "512x512" } ], "start_url": "/?source=pwa", "background_color": "#3367D6", "display": "standalone", "scope": "/", "theme_color": "#3367D6" }

It doesn’t look too hard, right? A couple of interesting things in this listing:

start-url: this determines where your app should start. It’s better to let users land on a specific page for you PWA.

display: this helps you determine what type of browser UI you want to show. Options are fullscreen, standalone, minimal-ui and the standard browser interface.

These three things listed above are the minimal requirements for running a PWA. You can expand the functionality via JavaScript (frameworks).

How to set up a PWA?

There are plenty of resources to try your hand at building a simple PWA. This allows you to get a feel for the process. Google has an excellent, easy to follow tutorial on PWAS on the web.dev site. Mozilla has lots of documentation on building progressive web apps. Microsoft also has rich developer docs on building PWAs. Microsoft even built a tool called PWABuilder that’ll help you turn your site into a PWA. Of course, there are WordPress plugins that help you make a PWA of your site. In addition, Google is working on bringing base-support for PWAs to WordPress Core.

Engage your users with a progressive web app

Progressive web apps can be a great addition to your mobile toolkit. Done well, they are fast, work offline and perform like a native app. All in all, they can offer your users an awesome user experience. Engaged users are happy users, right?

15 Top Prototyping Tools Go Head-to-Head

As the number and variety of prototyping tools continues to grow, it’s becoming harder and harder to figure out which tools meet what needs, and who they’re suitable for. Since we first wrote this article back in 2015, countless design apps have dominated (and changed) the prototyping space.

Stakeholder feedback and user testing is now taking a far greater role in UI design and this new generation of tools aims to connect these two previously separate stages of the design process. Clients want to be involved, and email isn’t cutting it anymore. Some apps like UXPin are also taking care of the wireframing stages, whereas others like InVision App are bridging the gap between designer and developer by offering design handoff tools.

Plus, there’s now a clear divide between desktop tools with cloud sharing (Adobe XD, Axure, Balsamiq, Sketch+InVision) and collaborative online tools (Figma, UXPin, Fluid UI, Proto.io).

Many of these tools appear to be converging on a feature set that defines the role of the modern user experience designer. TL;DR—here’s a swift comparison of prototyping tools.

Adobe XD

Adobe may have been caught napping during the rise of Sketch, but they’re rapidly making up for it with Adobe XD. Launched in March 2016, and still in beta as of July 2017, it’s the latest addition to Adobe’s Creative Cloud Suite. While you can prototype interactions in Sketch with the help of the Craft Plugin, Adobe XD impressively offers these tools right out of the box, so designers are already comparing Adobe XD to Sketch like longtime rivals.

It’s definitely worth a look if you’re interested in a tool that covers all your bases (low-fidelity prototyping, high-fidelity prototyping, user flows, sharing and feedback) in a single app.

Strengths

Available for macOS and Windows

Everything you need in a single app

Weaknesses

Still in beta (although pleasantly mature as a design app)

Plugin workflow non-existent, you’re locked into the Adobe ecosystem

InVision App (with Sketch and Craft)

InVision App is the largest and most successful design collaboration tool currently on the market, the primary go-to tool for serious designers and enterprise teams alike. With tools like whiteboard collaboration, dynamic prototyping, comments, device preview, video calling, user testing, version control and design handoff, InVision is already a colossal force in the prototyping space, but when you factor in its Sketch and Photoshop integrations, it becomes an all-in-one design suite, especially when you throw in Craft, the Sketch/Photoshop Plugin that brings a lot of that functionality directly into your design app of choice.

Strengths

Powerful, mature platform

Fully-integrated with Sketch for high-fidelity design

Constantly being updated with new features

Weaknesses

Feature-set can be a little overwhelming at first

Sketch is only available for macOS users only (but you can pair InVision with Photoshop on Windows, although Photoshop isn’t strictly a UI design tool)

Marvel App

A very strong favourite for those looking for simpler, friendlier alternatives to InVision App. Marvel App has excelled at creating a prototyping tool that works for both advanced UX designers and those simply looking to communicate high and low fidelity concepts. Plus, while they champion working with Sketch, they also offer component libraries to allow for a complete online workflow in Marvel. Marvel App also recently integrated fan-favourite POP, which allows designers to transform their pen/paper ideas into iPhone and Android apps.

Strengths

Great support for transitions for additional realism

Friendlier for non-designers, especially when giving feedback

Weaknesses

Web based only

No offline designing

UXPin

UXPin is the most complete online solution for UX designers in terms of their offering. While you can import from Sketch and Photoshop, you can also design complex and responsive interfaces with UXPin’s built-in libraries, making UXPin something of a wireframing tool as well. With their design systems features, UXPin becomes one of the most complex tools in terms of automated documentation, designer/developer handoffs and collaborative features.

Strengths

Responsive design with breakpoints

Powerful animations (not just linking screens)

Complete design collaboration and handoff solution

Weaknesses

A little pricey versus the competition at $49/user/month

Additional features increase the complexity of use

Webflow

Webflow is a visual tool for designing responsive websites that also exports clean code—it removes the headache of going from design to published on the web. Competing as much with WordPress as it does with Sketch App, Webflow lets you design fully functional responsive websites incorporating back-end (API) data and can automatically deploy to fully scalable, worry-free hosting with a single click of a button. It’s basically Adobe Dreamweaver for the modern-day designer who cares about clean code and mobile-friendly web design.

Strengths

Real data can be included (from APIs/JSON/etc)

Creates high-quality, reusable code

Responsive websites can be designed and deployed with ease

Weaknesses

Not useful for designing native mobile apps

Requires some knowledge of HTML/CSS to be at its most effective

Figma

A somewhat recent addition to the prototyping space, Figma boasts the most mesmerising real-time design collaboration features of any prototyping tool while modelling its feature-set on many of the intuitive design tools of Sketch and Adobe XD (such as symbols and device preview), along with a bunch of tools usually reserved for the online crowd (such as versioning and design handoff). Version 2.0, launched in July 2017, includes a prototyping mode with hotspots and developer handoffs to further streamline the design workflow. It works in the browser, on macOS, and on WIndows, although it sometimes can be slow.

Strengths

Real-time collaborative design features are second-to-none

Fully-featured, ideal for designers from start to finish

Weaknesses

Figma can can be laggy at time, especially with real-time collaboration

9 More Prototyping Tools Worth Considering

Fluid UI

With a strong focus on simplicity and communication, Fluid UI includes built-in high and low fidelity component libraries, live team collaboration, device previews and video presentations making it a top-notch solution for designers, product managers and founders alike.

Proto.io

Mature and feature-rich, Proto.io is best used by designers looking to create high-fidelity and highly-animated prototypes in the browser.

Axure RP 8

Established way back in 2003, Axure is an excellent choice for UX designers who need to create specifications for designs and animations in supreme detail. Axure’s includes support for conditional flow interactions, dynamic content and adaptive/responsive design, as well as high and low-fidelity prototyping. Axure is a serious tool for serious designers.

What is a progressive web app (PWA)? Why would you want one?

Edwin Toonen

Edwin is a strategic content specialist. Before joining Yoast, he spent years honing his skill at The Netherlands’ leading web design magazine.

What is a PWA?

Twitter.com is a PWA

What’s the difference between a native app and a PWA?

What are the benefits of a PWA?

We talked about some of the plusses of PWAs in this article, but here’s a short overview:

You don’t have to go through the process to get into different app stores

You can build PWAs with common web technologies

They are often cheaper to build

Since you’re turning your site into an app, you’ll have fewer code-bases to maintain

PWAs are responsive and work with many different screen sizes

PWAs are smooth, fast and lightweight

No need to hand off big chunks of money to Google and Apple

They work offline, unlike your regular site

PWAs are discoverable via search engines (which have a lot larger audience than app stores. Plus, if you want you can still get your PWAs distributed via app stores)

You can use push notifications to re-engage users

Installing a PWA can lead to higher engagement

All in all, it makes a lot of sense to think about having a PWA in your mobile strategy. But, the main question you should ask yourself is: does my audience want this?

Who’s this for?

PWAs are awesome and implementing them doesn’t have to be all that hard. But just because it’s easy doesn’t mean you should do it. If your audience has no need for it, why would you build one?

What are the SEO concerns of a PWA?

What are the three main building blocks?

It doesn’t take much to set up a PWA. There are three things you need to provide before your site turns into a valid PWA.

A service worker: A service worker is a piece of script that runs in the background. This helps you determine how to handle network requests for your PWA, making it possible to do more complex work.

The manifest file: This JSON file contains information on how your PWA should appear and function. Here, you determine the name, description, icons, colors, et cetera.

Here’s a sample manifest from Google:

It doesn’t look too hard, right? A couple of interesting things in this listing:

start-url: this determines where your app should start. It’s better to let users land on a specific page for you PWA.

display: this helps you determine what type of browser UI you want to show. Options are fullscreen, standalone, minimal-ui and the standard browser interface.

These three things listed above are the minimal requirements for running a PWA. You can expand the functionality via JavaScript (frameworks).

How to set up a PWA?

Engage your users with a progressive web app

What Students say:

“I appreciate the manner in which each project is presented, an example of an end result to which we need to build the relevant to reach the same output. It is a building block approach that works very well for me to comprehend the compartmentalisation of each component and the visualisation of the complete ‘picture’. Each component is then carefully unpacked through a process of visually understanding each characteristic and applying the ‘code’ to create the same. Marvelous.” Celia M Gaylard
