Dev Blog #2

Courtesy of Thell --

Last week we talked about user accounts and said that this week we’d talk about the new software stack, so let’s do that. On both new and old Cherp, the core technologies are staying roughly the same - we use PHP as the backend language that handles all the server side logic. This interacts with PostgreSQL as our database engine, and Redis acts as a caching layer between the two for information that takes a little while to get but that’s accessed often; things like your unread count, chat status, etc (Coincidentally, this is also the cause of the ghost unread bug - it caches your unread count for 24 hours unless it changes, but grace period and account deletes don’t decrement the counter. More on that in a minute). On the frontend, we currently use React, an abominable monstrosity that we’re glad to be dropping. Let’s talk about PHP first. Cherubplay was originally written in Python, but nobody really knew enough Python to fix that code up when it started breaking. As such, current Cherp uses PHP 7.4. This is about to leave active support meaning it’ll be receiving security updates only, meaning that for this rewrite, we’re switching to PHP 8. Right now, we’re coding with 8.0 in mind, but by the time we release, we’ll be on 8.1. It’s quite likely that we’ll be able to upgrade through all the 8.x versions after this with little issue. On top of PHP, current Cherp uses a microframework called Slim to provide some API routing stuff. For new Cherp, we’re using Laravel, something most PHP developers reading this will be familiar with. Personally, I prefer the older system (albeit with some major code touch ups needed), but that’s because I find MVC as a paradigm overly convoluted for what it does - but given Laravel is extremely widely used, and will make recruiting new devs easier in future, that’s what we’re going with. It gives us a lot of tools to work with, and so far, is making some things easier and some things harder. React is what you use right now to see the site. It’s awful, and we hate it. It’s a Javascript framework created by Facebook. For the new version, Laravel gives us a set of tools called Blade that lets us write the frontend in PHP. On top of this, there’s also a system called Livewire that we’re adding - this uses Blade as a basis, but adds some fancy dynamism on top so that you can have a similar experience to what you already have with dynamic elements. This way there’s a lot less Javascript involved, which means it’ll be easier on your computer and, if you’re one of those users who use mobile, your battery won’t drain as fast either. PostgreSQL (or Postgres, nobody can apparently decide how to refer to it) is the database we use. SQL is widely understood at this point by most techy people, but for those unaware, it stands for Structured Query Language. Ignore the people who tell you it’s pronounced “sequel”, they’re wrong and should be shunned (EDITOR'S NOTE: This opinion is incorrect). The most popular databases of this type are Postgres and MySQL (or MariaDB, a fork of MySQL that has a nicer license and which you should really be using instead). MySQL/MariaDB is a lot more popular than Postgres, but Postgres has a lot of extra flexibility. Most people don’t need this, but current Cherp uses Array datatypes. Arrays are very powerful, but - whether it’s just because of the way PHP forces you to use them and they’re better in other languages, or because the datatype itself kinda sucks - they’re absolutely awful to work with. For the rewrite, we’re keeping Postgres - even without using any of the advanced features, it’s powerful and fast, and if you give me 10 minutes alone in a room with it, I can make it do some impressive things. What we are doing is getting rid of arrays, and moving the stuff we use them for into a separate table. It’s one of those things that’s paradoxically both messier and cleaner, but it’ll reduce the load on PHP when it has to explode or implode the arrays when pulling/pushing to the database. Redis is also staying, though exactly how much use it’ll get right now is

debatable, and can only be answered once we’ve learned a little more about how Laravel handles things. Right now, we use it for login sessions and, as mentioned, caching. For those who don’t know, caching is where you store something that takes a long time to get to a faster place so it can be called faster. For example, let’s say I log in for the first time in a while. When I log in, the top bar needs to show how many unread chats I have, so it asks the database to count how many chats have me as a participant. Then, it filters these to find ones where my chat_status is marked “unread”. Then it gives the count back. Each step of this is slow, and takes time. It’s also something that’s requested on every page load, so rather than do it every time, we put a step in at the beginning and at the end - check Redis first. Redis stores everything in memory using key-value pairs. Redis has up to 16 “databases” - let’s say the unread_counts is database 2. So, it tells Redis to check database 2 for a value with key [whatever my user ID is]. If it’s there - it just spits the number out. If not, it’ll run through the process of asking the database, and when it’s done, it gives the number to Redis. There’s a few other places where this is done, and a few places where the cached number is ignored and forces another database check to refresh it, but broadly speaking, Redis cuts the performance cost of the site to about 20% of what it’d otherwise be. And there we go - a summary of what we’re using, both for the new site and the old one, as well as a little overview of what it does. If you’re in the Cherp Discord server (TT make this a link) (EDITOR'S NOTE: Ok, done), feel free to hop into the coding channel and I’ll answer any more in depth questions you have.

Thank you!

Top PHP benefits & frameworks 2021 for business enterprises

Introduced two decades ago in 1994, PHP is a general-purpose scripting language highly preferred in web development projects. Statista lists PHP in 8th position among the most used programming languages by developers across the globe.

You may find it surprising, but the scripting language was used for creating Facebook, Wikipedia, Tumblr, and many more. PHP powers a whopping 78.9% of all digital websites having a server-side programming language as per Web Development Stats.

So, are you thinking of using PHP to power your digital project? You have landed on the right page! Here you can explore the following:

Top benefits of using PHP.

What is a PHP framework?

How to choose the best PHP framework?

Top 7 PHP frameworks to go for in 2021.

Without wasting time, let's look at why PHP is a preferred choice for web development projects.

Top reasons/benefits of using PHP to power your web development project

Open-Source: It simply means you need not spend a penny to use the scripting language itself. Massive savings gets owing to the open-source nature of PHP.

done

Scalable: PHP is scalable and thus is suitable for both small-scale, mid-scale, and large-scale enterprises. Compatibility with tons of frameworks only enhances the scalability of the language. So, growing your website with a growing client base is never an issue with PHP development services India on your side.

Cross-platform compatibility: Reach a larger target audience as PHP is compatible with Linux, macOS, Unix, and Windows.

Shorter lines of code: PHP is renowned for working with shorter lines of code, saving time and hard work for the developer's team.

Mature Community Support: Worldwide, 26.2% of developers accept using PHP as a programming language. Hiring PHP developers in India also reduces web development costs by nearly 30%.

Significantly High-Speed: Unlike its immediate competitors, PHP owns its memory space, facilitating quicker code execution and a speedy digital platform.

Cloud Compatibility: PHP web apps are compatible with Cloud services, and the technology can get used with zero hindrance to enhance the accessibility and scalability of the web development project.

Suitable to both relational and non-relational DBMS: PHP is compatible with a range of database solutions irrespective of whether you want to go with a relational model like MySQL or a non-relational model like MongoDB.

Optimum Level of Security: While security issues have always been a concern with PHP, the truth is PHP is as secure as any other programming language. Enhancing the level of security depends actively upon following standard coding practices.

For example, being a trusted PHP development company in India, we follow strict adherence to secure coding practices resolving XSS, CSRF, SQLi, etc., from the project.

Having covered the top benefits of using PHP, let's look at the definition of a framework & guiding factors for choosing the best PHP framework.

What is a PHP framework?

A PHP framework is a platform for developers' teams to create web projects without writing mundane, repetitive codes. It comprises multiple pre-packaged functions & classes that facilitate rapid development of the PHP project in no time.

PHP frameworks eliminate the need for writing code from scratch and promote good coding practices & developing secured web apps for the business enterprise. The demand for advanced PHP frameworks is increasing and can be analyzed by looking at the infographic below: Listing the worldwide popularity of the PHP scripting language.

Source: Statista

Essential things to consider for choosing the best PHP framework

Clear your Goals & Objectives: You need to gain the exact vision of the features you want to integrate into the project. The chosen framework largely depends upon the project size and parts.

For example, an eCommerce website requires plentiful extensions, while a texting platform needs high connectivity.

Find out framework compatibility with the project features: Determine whether the chosen framework facilitates the development of the desired components or it would require tons of third-party integration.

Scalability of the framework: Framework plays a pivotal role in providing you with a scalable solution. Investigate whether the framework allows integration and disintegration of multiple modules.

User-friendly aspect of the framework: Well, this one largely depends upon the experience of the developers' team. We at PixelCrayons, offer PHP programmers India with an average of 5 years of experience facilitating the ideal framework for the web project.

Here are the top 7 PHP frameworks to go for in 2021

Laravel

Released in June 2011, Laravel holds a stunning 25.85% market share of the PHP framework. The open-source framework reduces the web development cost significantly and facilitates a high level of customization of the website. There are tons of reasons that make Laravel an indispensable PHP framework. Let’s have a quick look at them.

Pros of using Laravel as a PHP framework:

Availability of lightweight templates along with dynamic content seeding facilitates creating stunning layouts for the project.

Laravel supports customer-centric customization of the web app.

Multiple views of the web app can be created using the MVC architecture of Laravel. MVC structure also supports rapid & parallel development of the project.

Creating roles and permissions for different users is feasible with Laravel.

SEO-centric URLs get supported on Laravel.

Artisan Console is also available in Laravel. It acts as a command-line interface generating and structuring commands for the developer's team.

Tons of security-based features are available with Laravel, including encryption, authentication, email verification, etc.

Hashed passwords protect the users from credential-based data theft.

Developing a multilingual web app is feasible with Laravel.

Since its introduction, the framework has received more than 13 updates, which ensures users receive the latest and exciting features regularly.

Laravel libraries also offer the programmer's team to integrate password resetting options to the users.

Cons of using Laravel as a framework:

The upgraded versions of Laravel suffer from a lack of a proper continuation approach.

At times the upgrade leads to issues in the developed web app.

Examples of Laravel Projects: Vogue Archive, Rocket Rubbers, Mack Hankins, Orchestra Platform, etc.

Finding bugs and errors in the developed website or web app is much easier with CakePHP as a chosen framework. It effectively reduces the testing time of the web app.

Cons of using CakePHP framework

CakePHP documentation part of the framework needs improvement.

The framework demands one-way routing, which is considered a setback to the programming project.

Examples of CakePHP Projects: Good firms rating agency, Coconala website, Worldfilia advertising platform, etc.

Symfony Framework

Trusted by some of the worldwide renowned brands, including Spotify and Vogue, Symfony is a reliable framework for PHP development projects. The framework is highly preferred in eLearning, logistics, and healthcare-based projects. As per Builtwith Stats, Symfony powers more than 1,10,264 websites across the globe.

Pros of using Symfony as a PHP framework

Symfony promotes high productivity in the developer's team with reduced lines of coding.

The framework promotes writing clean and structured codes, which minimizes the chances of errors in coding.

Symfony gets timely updates, eliminating the risk of developing websites and web apps that get outdated with new technology. In other words, you can easily update the designed website with emerging technologies.

It comes with bundles that can get considered as a plugin. Decoupled features available in the bundles allow the coding team to reconfigure and reuse them in diverse ways.

Symfony can also get used with other popular frameworks like Laravel, Yii, etc., to enhance the functionalities of the web development project.

The framework also offers automated functional testing which reduces the risk of developing incorrect codes.

Cons of using Symfony framework:

The web app sometimes suffers from performance issues when using Symfony.

The designing stage of the web app consumes a significant amount of time.

Examples of Symfony Framework: Pornhub website for surfing porn, Trivago hotel chain, Spotify music streaming platform, etc.

The framework offers a modular structure for web development projects which means the developers team quickly integrates features into the project. The noticeable part of the FuelPHP framework: it supports both MVC and HMVC architecture.

Pros of using the FuelPHP framework:

It supports HMVC, which stands for Hierarchical Model View Architecture. HMVC effectively reduces the interdependency between different modules of the software.

Exceptional security-centric features like XSS filters, SQL injection prevention, CSRF preventions with tokens, etc., are available and can be customized with the FuelPHP framework.

The availability of secured features makes it suitable for developing apps for banks, financial institutions, etc.

The programmer's team can easily integrate multiple modules into the app due to the framework's well-documented features.

FuelPHP is a community-driven framework.So, getting aid from experienced developers is convenient with FuelPHP as your chosen framework.

Cons of using FuelPHP framework:

The new version of the framework requires longer dedicated hours from the team.

The GitHub stars stand at only 281.

Examples of FuelPHP Projects: Inventorybase, Spookies, etc.

Phalcon Framework

Developed by Andres Gutierrez, Phalcon is a web-based PHP framework with an MVC architecture. The framework is a trusted option for developing high-speed web apps as it can handle comparatively higher HTTPs requests per second.

Alpine.js: The JavaScript Framework That’s Used Like jQuery, Written Like Vue, and Inspired by TailwindCSS

We have big JavaScript frameworks that tons of people already use and like, including React, Vue, Angular, and Svelte. Do we need another JavaScript library? Let’s take a look at Alpine.js and you can decide for yourself. Alpine.js is for developers who aren’t looking to build a single page application (SPA). It’s lightweight (~7kB gzipped) and designed to write markup-driven client-side JavaScript.

The syntax is borrowed from Vue and Angular directive. That means it will feel familiar if you’ve worked with those before. But, again, Alpine.js is not designed to build SPAs, but rather enhance your templates with a little bit of JavaScript.

For example, here’s an Alpine.js demo of an interactive “alert” component.

CodePen Embed Fallback

The alert message is two-way bound to the input using x-model="msg". The “level” of the alert message is set using a reactive level property. The alert displays when when both msg and level have a value.

It’s like a replacement for jQuery and JavaScript, but with declarative rendering

Alpine.js is a Vue template-flavored replacement for jQuery and vanilla JavaScript rather than a React/Vue/Svelte/WhateverFramework competitor.

Since Alpine.js is less than a year old, it can make assumptions about DOM APIs that jQuery cannot. Let’s briefly draw a comparison between the two.

Querying vs. binding

The bulk of jQuery’s size and features comes in the shape of a cross-browser compatibility layer over imperative DOM APIs — this is usually referred to as jQuery Core and sports features that can query the DOM and manipulate it.

The Alpine.js answer to jQuery core is a declarative way to bind data to the DOM using the x-bind attribute binding directive. It can be used to bind any attribute to reactive data on the Alpine.js component. Alpine.js, like its declarative view library contemporaries (React, Vue), provides x-ref as an escape hatch to directly access DOM elements from JavaScript component code when binding is not sufficient (eg. when integrating a third-party library that needs to be passed a DOM Node).

Handling events

jQuery also provides a way to handle, create and trigger events. Alpine.js provides the x-on directive and the $event magic value which allows JavaScript functions to handle events. To trigger (custom) events, Alpine.js provides the $dispatch magic property which is a thin wrapper over the browser’s Event and Dispatch Event APIs.

Effects

One of jQuery’s key features is its effects, or rather, it’s ability to write easy animations. Where we might use slideUp, slideDown, fadeIn, fadeOut properties in jQuery to create effects, Alpine.js provides a set of x-transition directives, which add and remove classes throughout the element’s transition. That’s largely inspired by the Vue Transition API.

Also, jQuery’s Ajax client has no prescriptive solution in Alpine.js, thanks to the Fetch API or taking advantage of a third party HTTP library (e.g. axios, ky, superagent).

Plugins

It’s also worth calling out jQuery plugins. There is no comparison to that (yet) in the Alpine.js ecosystem. Sharing Alpine.js components is relatively simple, usually requiring a simple case of copy and paste. The JavaScript in Alpine.js components are “just functions” and tend not to access Alpine.js itself, making them relatively straightforward to share by including them on different pages with a script tag. Any magic properties are added when Alpine initializes or is passed into bindings, like $event in x-on bindings.

There are currently no examples of Alpine.js extensions, although there are a few issues and pull requests to add “core” events that hook into Alpine.js from other libraries. There are also discussions happening about the ability to add custom directives. The stance from Alpine.js creator Caleb Porzio, seems to be basing API decisions on the Vue APIs, so I would expect that any future extension point would be inspired on what Vue.js provides.

Size

Alpine.js is lighter weight than jQuery, coming in at 21.9kB minified — 7.1kB gzipped — compared to jQuery at 87.6kB minified — 30.4kB minified and gzipped. Only 23% the size!

Most of that is likely due to the way Alpine.js focuses on providing a declarative API for the DOM (e.g. attribute binding, event listeners and transitions).

Bundlephobia breaks down the two

For the sake of comparison, Vue comes in at 63.5kB minified (22.8kB gzipped). How can Alpine.js come in lighter despite it’s API being equivalent Vue? Alpine.js does not implement a Virtual DOM. Instead, it directly mutates the DOM while exposing the same declarative API as Vue.

Let’s look at an example

Alpine is compact because since application code is declarative in nature, and is declared via templates. For example, here’s a Pokemon search page using Alpine.js:

This example shows how a component is set up using x-data and a function that returns the initial component data, methods, and x-init to run that function on load.

Bindings and event listeners in Alpine.js with a syntax that’s strikingly similar to Vue templates.

Alpine: x-bind:attribute="express" and x-on:eventName="expression", shorthand is :attribute="expression" and @eventName="expression" respectively

Vue: v-bind:attribute="express" and v-on:eventName="expression", shorthand is :attribute="expression" and @eventName="expression" respectively

Rendering lists is achieved with x-for on a template element and conditional rendering with x-if on a template element.

Notice that Alpine.js doesn’t provide a full templating language, so there’s no interpolation syntax (e.g. in Vue.js, Handlebars and AngularJS). Instead, binding dynamic content is done with the x-text and x-html directives (which map directly to underlying calls to Node.innerText and Node.innerHTML).

An equivalent example using jQuery is an exercise you’re welcome to take on, but the classic style includes several steps:

Imperatively bind to the button click using $('button').click(/* callback */).

Within this “click callback” get the input value from the DOM, then use it to call the API.

Once the call has completed, the DOM is updated with new nodes generated from the API response.

If you’re interested in a side by side comparison of the same code in jQuery and Alpine.js, Alex Justesen created the same character counter in jQuery and in Alpine.js.

Back in vogue: HTML-centric tools

Alpine.js takes inspiration from TailwindCSS. The Alpine.js introduction on the repository is as “Tailwind for JavaScript.”

Why is that important?

One of Tailwind’s selling points is that it “provides low-level utility classes that let you build completely custom designs without ever leaving your HTML.” That’s exactly what Alpine does. It works inside HTML so there is no need to work inside of JavaScript templates the way we would in Vue or React Many of the Alpine examples cited in the community don’t even use script tags at all!

Let’s look at one more example to drive the difference home. Here’s is an accessible navigation menu in Alpine.js that uses no script tags whatsoever.

CodePen Embed Fallback

This example leverages aria-labelledby and aria-controls outside of Alpine.js (with id references). Alpine.js makes sure the “toggle” element (which is a button), has an aria-expanded attribute that’s true when the navigation is expanded, and false when it’s collapsed. This aria-expanded binding is also applied to the menu itself and we show/hide the list of links in it by binding to hidden.

Being markup-centric means that Alpine.js and TailwindCSS examples are easy to share. All it takes is a copy-paste into HTML that is also running Alpine.js/TailwindCSS. No crazy directories full of templates that compile and render into HTML!

Since HTML is a fundamental building block of the web, it means that Alpine.js is ideal for augmenting server-rendered (Laravel, Rails, Django) or static sites (Hugo, Hexo, Jekyll). Integrating data with this sort of tooling can be a simple as outputting some JSON into the x-data="{}" binding. The affordance of passing some JSON from your backend/static site template straight into the Alpine.js component avoids building “yet another API endpoint” that simply serves a snippet of data required by a JavaScript widget.

Client-side without the build step

Alpine.js is designed to be used as a direct script include from a public CDN. Its developer experience is tailored for that. That’s why it makes for a great jQuery comparison and replacement: it’s dropped in and eliminates a build step.

While it’s not traditionally used this way, the bundled version of Vue can be linked up directly. Sarah Drasner has an excellent write-up showing examples of jQuery substituted with Vue. However, if you use Vue without a build step, you’re actively opting out of:

the Vue CLI

single file components

smaller/more optimized bundles

a strict CSP (Content Security Policy) since Vue inline templates evaluate expressions client-side

So, yes, while Vue boasts a buildless implementation, its developer experience is really depedent on the Vue CLI. That could be said about Create React App for React, and the Angular CLI. Going build-less strips those frameworks of their best qualities.

There you have it! Alpine.js is a modern, CDN-first library that brings declarative rendering for a small payload — all without the build step and templates that other frameworks require. The result is an HTML-centric approach that not only resembles a modern-day jQuery but is a great substitute for it as well.

If you’re looking for a jQuery replacement that’s not going to force you into a SPAs architecture, then give Alpine.js a go! Interested? You can find out more on Alpine.js Weekly, a free weekly roundup of Alpine.js news and articles.

Alpine.js: The JavaScript Framework That’s Used Like jQuery, Written Like Vue, and Inspired by TailwindCSS

For example, here’s an Alpine.js demo of an interactive “alert” component.

It’s like a replacement for jQuery and JavaScript, but with declarative rendering

Alpine.js is a Vue template-flavored replacement for jQuery and vanilla JavaScript rather than a React/Vue/Svelte/WhateverFramework competitor.

Since Alpine.js is less than a year old, it can make assumptions about DOM APIs that jQuery cannot. Let’s briefly draw a comparison between the two.

Querying vs. binding

Handling events

Effects

Also, jQuery’s Ajax client has no prescriptive solution in Alpine.js, thanks to the Fetch API or taking advantage of a third party HTTP library (e.g. axios, ky, superagent).
