Crafting SEO-Friendly Websites: A Developer’s Roadmap to Visibility

In today’s digital ecosystem, a website’s success hinges not just on sleek design or functionality, but on its ability to be found. For developers, weaving SEO into the fabric of your build process isn’t optional—it’s critical. At CodingNectar.com, we’ve seen how SEO-savvy development drives traffic and growth. Let’s break down how to engineer websites that both users and search engines love.

1. Architect with SEO in Mind

A website’s structure is its backbone. Imagine constructing a skyscraper: without a blueprint, chaos ensues.

Flat Architecture Wins:

Keep pages within 3–4 clicks from the homepage for easy crawling.

Avoid orphan pages—every page should link back to your main navigation.

URLs That Speak Clearly:

Ditch cryptic strings like /page123. Opt for descriptive paths (e.g., /guides/seo-for-devs).

Use hyphens (-) to separate words—search engines read them as spaces.

Pro Tip: Tools like Screaming Frog act as X-ray goggles, uncovering broken links or duplicate content.

2. Nail Technical SEO Foundations

Think of technical SEO as the plumbing—it’s invisible but essential.

Mobile-First Isn’t a Trend, It’s a Rule:

Use responsive frameworks (e.g., Bootstrap) and test with Google’s Mobile-Friendly Tool.

Speed Is Non-Negotiable:

Compress images to WebP format (tools: ImageOptim).

Minify CSS/JS files and leverage browser caching.

Guide Search Engines:

Generate an XML sitemap.

Block irrelevant pages (e.g., test environments) via robots.txt.

3. Semantic HTML: SEO’s Best Friend

Clean code isn’t just for developers—it’s a love letter to search engines.

HTML5 Tags Are Your Allies:

Use <header>, <nav>, and <article> to add context.

Headings Hierarchy Matters:

One <h1> per page (your title), followed by logical <h2>-<h6>.

Alt Text: Describe, Don’t Keyword-Stuff:

alt="developer optimizing website speed" beats alt="SEO tips".

4. Ace Core Web Vitals

Google’s user experience metrics can make or break your rankings.

Largest Contentful Paint (LCP):

Target <2.5 seconds. Optimize hero images and lazy-load offscreen content.

First Input Delay (FID):

Defer non-critical JavaScript.

Cumulative Layout Shift (CLS):

Reserve image/video space with width and height attributes.

Test Tools: Google PageSpeed Insights and Lighthouse are your go-to auditors.

5. Content: Where Code Meets Strategy

Developers wear many hats—content strategist included.

Keyword Research:

Tools like Ahrefs uncover gems (e.g., “optimize Angular SEO” vs. generic terms).

SPA Challenges:

Use server-side rendering (Next.js/Nuxt.js) for React/Angular apps.

Canonical Tags:

Fix duplicate content with <link rel="canonical" href="https://your-primary-url">.

6. Security & Accessibility: SEO’s Silent Allies

HTTPS is Mandatory:

Free SSL via Let’s Encrypt boosts trust and rankings.

Accessibility Enhances SEO:

ARIA labels (e.g., aria-label="Contact form") aid screen readers and search bots.

7. Structured Data: Speak Google’s Language

Schema markup helps search engines “get” your content.

JSON-LD Example:

html

Copy<script type="application/ld+json"> { "@context": "https://schema.org", "@type": "Guide", "name": "SEO for Developers", "author": "CodingNectar.com" } </script> Run HTML

Validate with Google’s Structured Data Tool.

8. Monitor, Tweak, Repeat

SEO is a marathon, not a sprint.

Track Progress:

Google Search Console reveals crawl errors and keyword performance.

Moz or Ahrefs monitor rankings.

Fix Issues Promptly:

Redirect broken links (301s) and refresh stale content.

Avoid These SEO Blunders

Neglecting Mobile: Most searches happen on phones.

JavaScript Overload: Heavy scripts slow crawlers.

Duplicate Content: Canonical tags are your safety net.

Cheap Hosting: Slow servers = lost rankings.

Final Take: SEO is Part of Your Code

Building SEO-friendly sites isn’t about gaming algorithms—it’s about creating fast, accessible, and intuitive experiences. By embedding SEO into your development DNA, you’ll future-proof your work and unlock organic growth. At CodingNectar.com, we’ve turbocharged rankings for everyone from startups to Fortune 500s by merging technical rigor with SEO strategy.

How I Launched SpellZen for Just $12

Launching a startup can feel daunting and expensive. But when I set out to build SpellZen.com, my goal was to create a simple, user-friendly spelling tool without breaking the bank. In the end, I spent just $12—all for the domain name. Here’s how I did it.

From Idea to Launch in Under a Month

I started working on SpellZen on December 16, 2023, and launched on January 12, 2025. In less than a month, I went from concept to a working site. During that time, I explored local LLMs like Ollama and OpenWebUI, and even dabbled with AI integrations in Minecraft—just to see what AI could really do.

I treated AI like a junior developer, clearly defining tasks, giving examples, and providing detailed guidelines. This approach allowed me to leverage AI effectively to produce reliable and adaptable code that met my goals.

What began as a desire for a quick, focused spelling and definition tool evolved into a more robust platform with scalability in mind. Despite the short timeline, SpellZen quickly became something I’m proud to call a startup.

Keeping Costs Low

1. Buying the Domain

I found SpellZen.com for $12 at a budget-friendly registrar—no fancy add-ons needed.

2. Building It Myself

I coded the site using .NET 9 and Blazor for a responsive, modern interface that prioritized speed and simplicity. AI played a major role in refining spell-check features, especially when it came to turning my prototypes into production-ready code. I approached AI like a collaborator, iteratively testing and improving its output until it aligned with my vision.

3. Hosting on Azure Free Tiers

I used Microsoft Azure—specifically a free-tier VM, CosmosDB, and Azure Active Directory B2C—to keep hosting costs at zero. SSL certificates came via Let’s Encrypt and win-acme, also free.

4. Caching and Rate Limiting

To keep performance strong and expenses low, I implemented caching and rate-limiting, which helped balance resource use without upgrading to pricier database tiers.

5. Core Features First

Instead of piling on features, I launched with spell-check, definitions, and usage examples. This “keep-it-simple” approach led to a solid MVP that I can expand on later.

6. Time Over Money

The real expense was my time—working late nights and early mornings to get SpellZen ready for launch. Even so, it was worth every minute to see the vision come to life in under a month.

Running Costs

While the initial launch cost was minimal, there are some ongoing expenses to keep SpellZen running smoothly:

AI API Usage: I opted for a low-token application setup to minimize costs associated with the AI API. This ensures that SpellZen remains efficient without incurring hefty fees.

VM IP Address Fee: There is a small fee for the IP address that the Azure Virtual Machine uses. However, with the $200 Azure credit you receive upon opening an account, this cost is significantly offset, allowing the credit to go a long way in covering these minor expenses.

These running costs are kept to a minimum, ensuring that SpellZen remains affordable while providing a reliable service to its users.

The Hiccups (and How I Fixed Them)

Of course, it wasn’t all smooth sailing. I ran into a few bumps:

CosmosDB Free-Tier Limitations: I initially expected multiple free containers but discovered I only got one. A quick fix (with AI’s coding help) got the database structure updated fast.

Azure AD B2C Challenges: The documentation for Azure Active Directory B2C lacked clarity. Trying out different configurations tested my patience, but ultimately, it worked—and saved me from picking a costlier solution like Auth0.

AI Output Issues: Sometimes, the AI-generated code didn’t align with my expectations. At times, it added or removed code in unexpected ways, requiring extra review and debugging. While frustrating, these instances reminded me to double-check everything and to treat AI output as a starting point, not a final solution.

SSL Setup: I was used to paying more than $60 for an SSL. Let’s Encrypt and win-acme made things free and simple to set up on a VM. Though I initially dreaded using Let’s Encrypt, win-acme made the process surprisingly easy.

These hiccups were frustrating at times, but they taught me how to be resourceful and confirmed that sticking to free or low-cost solutions can still yield professional results.

Why I Believe It’s Worth It

By starting small, I gave myself the space to learn, adapt, and grow. SpellZen is now more than just a website—it’s a foundation that can evolve alongside its users. It’s also a demonstration of how AI can be harnessed for good: to help us communicate more effectively without overwhelming complexity.

AI for Good

I believe AI should make life better. SpellZen is a small example of how AI can help people sharpen their skills and write with confidence. Hopefully, it encourages others to use AI in ways that build us up, spark creativity, and simplify everyday tasks.

My Takeaway

You don’t need a huge budget to make something meaningful. If you have a clear vision and you’re willing to put in the work, you can build and launch your idea—even for the price of a few snacks. So, if you’ve been sitting on a project, start small, stay focused, and bring it to life. You never know where it might lead.

Ready to see it for yourself? Check out SpellZen.com. And remember—don’t Google it… SpellZen it!

FAQs

Why is clearing cache on Windows 10 important? Clearing cache helps in enhancing the speed and performance of your system. Over time, accumulated cache can slow down your computer and hinder its functionality. How often should I clear my browser cache? While there's no strict rule, it's generally recommended to clear browser cache every 4-6 weeks. This ensures you're viewing the most updated versions of webpages and prevents websites from loading slowly. Does the "wsreset" command clear cache for all Windows apps? The "wsreset" command is specifically designed to reset the Microsoft Store. It clears the cache of the Microsoft Store app, which can solve certain functionality issues. Are there any risks associated with clearing Windows Update Cache? While clearing the Windows Update Cache can solve update-related issues, there is a slight risk. Deleting the wrong files can cause further update complications. Always ensure you're following the steps correctly and only deleting contents inside the specified folder. What does the "ipconfig /flushdns" command do? This command is used to clear the DNS (Domain Name System) cache. DNS cache stores the IP addresses of web servers that contain recently viewed websites. By clearing it, you're removing all the old and possibly incorrect entries, which can resolve some connectivity issues. After clearing cache, will my computer instantly speed up? In many cases, clearing cache can lead to noticeable improvements in speed. However, the first time you revisit certain applications or websites, they might load slightly slower as they rebuild their cache. Do I need third-party software to clear cache? While the methods mentioned in the article utilize built-in Windows features, there are third-party software options that can automate and provide deeper cleaning. However, always download such software from reputable sources to avoid malware. Why do thumbnails need cache? Thumbnails use cache to quickly display previews of content, such as pictures or videos, without needing to fully load the file. Clearing the thumbnail cache can help when these previews aren't displaying correctly. Is clearing cache the same as deleting my saved files and data? No, clearing cache will not delete personal files or essential data. Cache consists of temporary files meant to speed up tasks. When cleared, some tasks might take slightly longer the first time as the cache rebuilds. Can I selectively choose what cache to clear? Yes, tools like "Disk Cleanup" provide options on which types of cache and temporary files you wish to clear, offering users flexibility in their cleaning process. Read the full article

A new report on the industry discovered that companies are moving to headless CMS over traditional ones to distribute content to their intended audience because of their versatility.

10. Static Web Hosting

2021 isn't going to remain an unexceptional year. Netlify and JAMstack are two manners of hosting service which has gained a lot of attention in web development over the past few years. Netlify offers advanced web hosting features that are integrated with automation, while JAMstack improves the performance of websites principally regarding speed.

The development of websites has completely changed throughout the decades. Nowadays, websites are developed and designed with the latest standards in mind and the most recent technology. This is why web developers have to always keep up with the newest developments and constantly improve their ability to develop amazing websites.

Primary Dns Server Address

Scroll up the information in the window to the 'DNS Servers' item on the left side. To the right you will see your computer's primary DNS server address as well as its secondary one (if your.

Optimum DNS Servers. Primary DNS: 167.206.112.138. Secondary DNS: 167.206.7.4.

According to this link and the Windows Server 2008 R2 Best Practices Analyzer, the loopback address should be in the list, but never as the primary DNS server. In certain situations like a topology change, this could break replication and cause a server to be 'on an island' as far as replication is concerned.

Primary And Secondary Dns Server Address

What Is My Dns Server

You may see a DNS server referred to by other names, such as a name server or nameserver, and a domain name system server. The Purpose of DNS Servers It's easier to remember a domain or hostname like lifewire.com than it is to remember the site's IP address numbers 151.101.2.114.

Nslookup (name server lookup) is a command-line tool that is used to diagnose and validate DNS servers and records, and to find name resolution problems in the DNS subsystem. The nslookup tool was originally developed as a part of the BIND package and ported to Windows by Microsoft. Nslookup is currently a built-in tool in all supported versions of Windows.

How to Use Nslookup to Check DNS Records?

Using the nslookup utility, you can determine the IP address of any server by its DNS name, perform the reverse DNS lookup, and get information about the various DNS records for a specific domain name.

When running, Nslookup sends queries to the DNS server that is specified in your network connection settings. This address is considered the default (preferred) DNS server. My phone ip. The user can specify the address of any other available DNS server. As a result, all subsequent DNS requests will be sent to it.

You can view or change your preferred and alternative DNS server IP addresses in the network connection properties.

Or you can get your DNS server setting from the CLI prompt using the ipconfig command:

You can use the nslookup tool in interactive or non-interactive mode.

To run a DNS query using nslookup tool in non-interactive mode, open a Command prompt, and run the command:

In this example, we requested the IP address of theitbros.com domain. The nslookup utility queries the DNS server (it is specified in the Server line) and it returned that this name matches the IP address 37.1.214.145 (A and AAAA records are shown by default).

This response indicates that your DNS server is available, works properly, and processes requests for resolving DNS names.

If you received such an answer:

Server: dns1.contoso.com

Address: хх.хх.хх.хх

*** dns1.contoso.com can’t find theitbros.com: Non-existent domain

This means that no entries were found for this domain name on the DNS server.

If your DNS server is unavailable or not responding, you will receive a DNS request timed out error.

In this case, check if you have specified the correct DNS server address and whether there is a problem with the network connection from the IS provider.

It includes Auto Mode, for real-time correction and effects, Graph Mode, for detailed pitch and time editing, and the Auto-Key plug.

READ ALSOFixing DNS Server Not Responding Error on Windows 10

The Non-authoritative answer means that the DNS server that executed the request is not the owner of the theitbros.com zone (there are no records about this domain in its database) and to perform name resolution a recursive query to another DNS server was used.

You can enable and disable the recursive nslookup mode using the commands (by default, recursive DNS queries are enabled):

You can access an authoritative DNS server by specifying its address directly in the parameters of the nslookup utility. For example, to resolve a name on the authoritative DNS server (that contains this domain) use the command:

When you run nslookup without parameters, the utility switches to the interactive mode. In this mode, you can execute various commands. A complete list of available internal commands of the nslookup utility can be displayed by typing a question.

Tip. Note that nslookup commands are case sensitive.

To close the interactive nslookup session, type exit and press Enter.

To find the DNS servers that are responsible for a specific domain (Name Server authoritative servers), run the following commands:

You can perform reverse lookups (get DNS name by IP address). Just type the IP address in the nslookup interactive prompt and press Enter.

Using Nslookup to Get Different DNS Record Types

The default nslookup resource records type is A and AAAA, but you can use different types of resource records:

A

ANY

CNAME

GID

HINFO:

MB

MG

MINF

MR

MX

NS

PTR

SOA

TXT

UID

UINFO

WKS

You can set specific record types to lookup using the nslookup parameter:

For example, to list all mail servers configured for a specific domain (MX, Mail eXchange records), run the command:

Non-authoritative answer:

theitbros.com MX preference = 10, mail exchanger = mail.theitbros.com

theitbros.com MX preference = 20, mail exchanger = mail.theitbros.com

mail.theitbros.com internet address = 37.1.214.145

mail.theitbros.com internet address = 37.1.214.145

As you can see, this domain has 2 MX records with priorities 10 and 20 (the lower the number, the higher the priority of the MX address). If you don’t see MX records, they probably just aren’t configured for that domain.

To list all DNS records in the domain zone, run the command:

Non-authoritative answer:

theitbros.com internet address = 37.1.214.145

theitbros.com nameserver = ns2.theitbros.com

theitbros.com nameserver = ns1.theitbros.com

theitbros.com MX preference = 10, mail exchanger = mail.theitbros.com

theitbros.com MX preference = 20, mail exchanger = mail.theitbros.com

ns2.theitbros.com internet address = 74.80.224.189

ns1.theitbros.com internet address = 37.1.214.145

mail.theitbros.com internet address = 37.1.214.145

mail.theitbros.com internet address = 37.1.214.145

To get the SOA record (Start of Authority – start DNS zone record, which contains information about the domain zone, its administrator’s address, serial number, etc.), use the option -type=soa:

theitbros.com

primary name server = pdns1.registrar-servers.com

responsible mail addr = hostmaster.registrar-servers.com

serial = 1601449549

refresh = 43200 (12 hours)

retry = 3600 (1 hour)

expire = 604800 (7 days)

default TTL = 3601 (1 hour 1 sec)

pdns1.registrar-servers.com internet address = 156.154.130.200

pdns1.registrar-servers.com AAAA IPv6 address = 2610:a1:1022::200

primary name server;

responsible mail addr — domain administrator email address (hostmaster@registrar-servers.com). Since the @ symbol in the zone description has its own meaning, it is replaced by a dot in this field);

serial — the serial number of the zone file, used to record changes. The following format is usually used: YYYYMMDDHH;

refresh — the period of time (in seconds) after which the secondary DNS server will send a request to the primary one to check if the serial number has changed;

retry — specifies the interval for reconnecting to the primary DNS server if for some reason it was unable to respond to the request;

expire — specifies how long the DNS cache is kept by the secondary DNS server, after which it will be considered expired;

default TTL — “Time to Live” seconds. Refers to how long your DNS settings must be cached before they are automatically refreshed.

If you want to list the TXT records of a domain (for example, when viewing SPF settings), run the command:

The debug option allows you to get additional information contained in the headers of client DNS requests and server responses (lifetime, flags, record types, etc.):

You can view the current values for all specified nslookup options with the command:

By default, DNS servers listen on UDP port 53, but you can specify a different port number if necessary using the -port option:

or interactively:

You can change the interval to wait for a response from the DNS server. This is usually necessary on slow or unstable network links. By default, if no response comes within 5 seconds, the request is repeated, increasing the waiting time by two times. But you can manually set this value in seconds using the -timeout option:

So, in this article, we covered the basics of working with the nslookup command on Windows.

If the directory is removed from IIS, but remains in AD, you must first remove the directory from AD using the Remove-XXXVirtualDirectory cmdlet (where XXX is the name of the directory: ECP, OWA, etc.).

If the directory is still in IIS but is not present in the Active Directory configuration, you must remove it from the IIS configuration. To do this, we need the Metabase Explorer tool from the IIS 6 Resource Kit (requires Net Framework 3.5 Feature).

Launch IIS Metabase Explorer, go to Exchange > LM > W3SVC > 1 > ROOT. Delete the directory you want by right-clicking on it and choosing Delete.

Restart IIS:

Now attempt to create the virtual directory again using the New-EcpVirtualDirectory, New-OwaVirtualDirectory, or New-WebApplication cmdlets

Progressive Web Apps

Everything You Should Know About Progressive Web App

Progressive net Apps may be a net application that takes advantage of contemporary browser options and might be additional to your home screen, behaving rather like a native application. In this tutorial we're aiming to show you everything you wish to understand regarding PWAs, step by step, with sensible examples and a demo app. To not begin from scratch, we have a tendency to square measure aiming to use the selfie app we have a tendency to created recently, and build it progressive. What is a Progressive Web App

In its core a progressive net app is not any totally different from a traditional web site - it's made from HTML, CSS and JavaScript, and lives within the browser. What separates PWAs from regular websites may be a list of ten key ideas that require to be consummated. Here there, taken directly from the Google Developers web site. 1.

Safe

- Served via HTTPS to prevent snooping and ensure content hasn’t been tampered    with.2.

Progressive

- Work for every user, regardless of browser choice because they’re built with    progressive enhancement as a core tenet.3.

Responsive

- Fit any form factor: desktop, mobile, tablet, or whatever is next.4.

Connectivity-independent

- Enhanced with service workers to work offline or on low    quality networks.5.

App-like

- Feel like an app to the user with app-style interactions and navigation because    they’re built on the app shell model.6.

Fresh

- Always up-to-date thanks to the service worker update process.7.

Discoverable

- Are identifiable as “applications” thanks to W3C manifests and service worker registration scope allowing search engines to find them.8.

Re-engageable

- Make re-engagement easy through features like push notifications.9.

Installable

- Allow users to “keep” apps they find most useful on their home screen without the hassle of an app store.10.

Linkable

- Easily share via URL and not require complex installation. Following these guidelines will ensure that your app works well not only when viewed in the browser, but also when started separately via a home screen shortcut. You may find the wording Google has chosen rather confusing, but don't worry, we will explain the rules one by one later in the tutorial.

What a Progressive Web App is NOT

The concept of PWAs shouldn't be confused with:

·

Cordova

based hybrid apps·

React Native

·

NativeScript

·

Electron

and

NW.js

 All of the said technologies wrap markup language apps and package them into workable files, be it an .apk, .exe or the rest, that then have to be compelled to be downloaded from the various app store and put in on the user's device. PWAs do not need installation and are not obtainable (yet) in Google Play or the iTunes App store. To transfer a PWA you would like to easily visit it's web site so put it aside to the house screen as a cutoff. Developing and maintaining separate iOS and automaton versions is not any longer a problem, however browser support has to be taken into thought.

1. Safe

Most progressive internet apps work with native genus Apis and repair employees, technologies that manage sensitive information and wish to be handled with caution. That is why each PWA has got to be served through a HTTPS affiliation. If you do not have access to a server with a SSL certificate, the best method run comes in a very secure surroundings is via GitHub Pages or the same service. Any GitHub repository are often hosted directly over HTTPS, and each GitHub and GitHub Pages area unit free for public repos. For simple testing on a neighborhood server, you'll additionally attempt Ngrok. It’s a small tool that permits you to tunnel any presently running local host to a secure public uniform resource locator. Ngrok is free and obtainable for Windows, Mac, and Linux.

2. Progressive

Essentially, what this suggests is that PWAs ought to use internet technologies that square measure wide supported and work equally well on as several browsers as potential. As we tend to all recognize, within the world of internet development this is often about to not possible, however still there square measure things we will do to hide a bigger user base. For example, in our PhotoBooth app we tend to use the getUserMedia() API for accessing the hardware camera on a tool. Its support in several browsers is sort of inconsistent - hunting expedition does not support it in the slightest degree, the browsers that do support it would like prefixes and take issue in usage. To ensure additional individuals will really use our app, we tend to cowl all the prefixes:

navigator.getMedia = (  navigator.getUserMedia ||  navigator.webkitGetUserMedia ||  navigator.mozGetUserMedia ||  navigator.msGetUserMedia );

We also show an error if none of the prefixes work:

if (!navigator.getMedia) { displayErrorMessage("Your browser doesn't have support for the navigator.getUserMedia interface."); } else { // Use Camera API }

Fallbacks and polyfills should be provided where possible. The same principles go for the CSS and HTML code.

3. Responsive

The app ought to look nice on all devices, notwithstanding their screen size. Our app encompasses a fairly straightforward UI therefore we've used solely one or two of media queries to regulate font-size, paddings, margins, etc. Don't be afraid to use CSS libraries and frameworks like Bootstrap, as they create it very easy to make grids, and influence typography and general responsiveness.

4. Connectivity independent

This is a vital one. victimization service staff permits your app to figure even once there's no net affiliation on the market. Some apps may be cached solely partially: UI is cached and on the market offline, dynamic content still wants access to a server. Others, like our PhotoBooth demo, may be cached in their totality. All of the ASCII text file and resources are going to be saved regionally and also the app can work offline and on-line precisely the same means. Here is that the code that creates the magic happen:

This is an oversimplified usage of Service Workers, use with caution in commercial projects.

First we need to make a service worker JavaScript file, and define the logic behind it.

sw.js

// Install the service worker. this.addEventListener('install', function(event) { event.waitUntil( caches.open('v1').then(function(cache) { // The cache will fail if any of these resources can't be saved. return cache.addAll([ // Path is relative to the origin, not the app directory.  '/pwa-photobooth/', '/pwa-photobooth/index.html', '/pwa-photobooth/assets/css/styles.css', '/pwa-photobooth/assets/fonts/MaterialIcons-Regular.woff2', '/pwa-photobooth/assets/js/script.js', '/pwa-photobooth/assets/icons/ic-face.png', '/pwa-photobooth/assets/icons/ic-face-large.png', '/pwa-photobooth/manifest.json' ]) .then(function() { console.log('Success! App is available offline!'); }) }) ); }); // Define what happens when a resource is requested. // For our app we do a Cache-first approach. self.addEventListener('fetch', function(event) { event.respondWith( // Try the cache. caches.match(event.request) .then(function(response) { // Fallback to network if resource not stored in cache. return response || fetch(event.request); }) ); });

Then we need to link that service worker to our HTML.

index.html

<script> // Register Service Worker. if ('serviceWorker' in navigator) { // Path is relative to the origin, not project root. navigator.serviceWorker.register('/pwa-photobooth/sw.js') .then(function(reg) { console.log('Registration succeeded. Scope is ' + reg.scope); }) .catch(function(error) { console.error('Registration failed with ' + error); }); } </script>

Now all of the files in our project will be saved in the user's browser. Any JavaScript variables and object should also be saved in the localStorage or IndexDB where possible. Right now Service Workers are supported in Chrome, Firefox and Opera. Safari and Edge are also working towards adopting them, and we hope that in the future they will be available in every browser.

5. App-like

When building PWAs, it's counseled to follow a style idea referred to as app-shell design. It sounds terribly sophisticated however basically boils all the way down to this: the app is separated into 2 major components: the shell and also the content. The shell contains all the static UI components like a header, menus, drawers, etc. once we cache associate degree app, the shell should be saved on the device, as a result of we wish it to be on the market in the slightest degree times. That method once a user with no web association opens the app, they will not see associate degree empty screen or a running archosaur - they'll see the cached app interface associate degreed an applicable error message.

The content resides within the shell. It can also be cached but it isn't necessary to do so as content is usually dynamic, changes frequently and can be different on every single page load.

6. Fresh

Once cached, our PWA will always load from the local storage. However, if we change the service worker sw.js in any way, on the next page load the new version will be downloaded and installed.

this.addEventListener('install', function(event) { event.waitUntil( caches.open('v1.0.1').then(function(cache) { // ... }) ); });

Using service worker updates we can re-download resources, delete old cache, or completely change the service worker logic. You can learn more about the SW Update process from the Google Developers article.

7. Discoverable

By adding an online Manifest to our app we are able to give varied info regarding it and alter the manner it's displayed on people's devices. It permits apps to be saved to the house screen with a custom icon, to be started during a separate browser window, and a great deal of different cool stuff.

The Web Manifest takes the form of a simple JSON file:

manifest.json

{ "name": "Progressive Web App: PhotoBooth", "short_name": "PhotoBooth", "description": "Simple Progressive Web App for taking selfies.", "icons": [{ "src": "assets/icons/ic-face.png", "type": "image/png", "sizes": "72x72" }, { "src": "assets/icons/ic-face-large.png", "type": "image/png", "sizes": "144x144 256x256" }], "start_url": "index.html", "display": "standalone", "background_color": "#fff", "theme_color": "#fff", "orientation": "portrait" }

Most of the properties are self explanatory so we will cover only the more important ones. See the full Web manifest format and all the available fields.

· Shortname - This is the name our app will have when saved to the home screen.· Icons - Array of icons with different resolutions.· Display - Defines how the app will be opened. We've chosen standalone so when started our photo booth will appear in a full-screen window without any browser navigation or menus. It will also be seen as a separate app in multitasking.

To register the manifest we have to link it to our HTML:

<!-- Web Manifest --> <link rel="manifest" href="manifest.json">

Safari doesn't support the Web Manifest standard yet but we can define app-like behavior with this Apple-specific meta tag:

<!-- Meta tag for app-like behaviour in iOS --> <meta name=”apple-mobile-web-app-capable” content=”yes”>

8. Re-engageable

Push notifications are not restricted to native apps to any extent further. because of service employees and also the Push API, internet applications also can send messages to the humanoid notification bar. Not all apps can enjoy having this feature, however once used properly notifications will extremely facilitate interact users. This topic goes on the far side the scope of our tutorial, as Push Notifications area unit quite difficult and merit a full lesson on their own. If you continue to need to implement notifications to your internet app, here area unit a number of the simplest learning resources available: · Google Developers, Push Notifications: Timely, Relevant, and Precise -

here

.· Google Developers, Push Notifications on the Open Web -

here

.· MDN, Using the Push API -

here

.· Push.js, Library that provides a cleaner API for handling push notifications -

here

.

9. Installable

By default any web site may be manually saved to the house screen victimization the increase Home Screen button from the Chrome browser menu. However, it'd be rather tough to create users "install" our app this fashion, since the majority do not know this feature in the slightest degree. Thankfully, there's how for your app to prompt users to save lots of it with a straightforward installation pop-up. To stop developers from abusing these pop ups, there's not any thanks to programmatically show them. Instead, they'll seem on their own once Associate in Nursing app fulfills a series of requirements:

1. There is a valid Web Manifest.2. There is a valid Service Worker installed.3. The app is served over HTTPS.

We have all of the above covered, so when a user visits our app's website a couple of times, they will get this prompt:

The entire installation process of our app is in this simple prompt. The install happens instantly, and once saved the PhotoBooth will be available to launch from a home screen icon, behaving exactly like a native app.

11. Linkable

Anyone with an internet browser has access to PWA apps and that they is shared merely via their universal resource locator. No third party tools area unit needed for locating or putting in them.

If associate app runs in standalone mode, it is also suggested to feature in-app share buttons, since the browser address bar and menus are not visible.

Conclusion

Our PWA is now complete. We can test how well it follows the PWA rules with an official Google-made tool called

Lighthouse

. It recreates possible scenarios and tests the app thoroughly. Here is what it tells us about the PhotoBooth:

We passed!

App is available offline!'); }) }) ); }); // Define what happens when a resource is requested. // For our app we do a Cache-first approach. self.addEventListener('fetch', function(event) { event.respondWith( // Try the cache. caches.match(event.request) .then(function(response) { // Fallback to network if resource not stored in cache. return response || fetch(event.request); }) ); });Then we need to link that service worker to our HTML.index.html<script> // Register Service Worker. if ('serviceWorker' in navigator) { // Path is relative to the origin, not project root. navigator.serviceWorker.register('/pwa-photobooth/sw.js') .then(function(reg) { console.log('Registration succeeded. Scope is ' + reg.scope); }) .catch(function(error) { console.error('Registration failed with ' + error); }); } </script>Now all of the files in our project will be saved in the user's browser. Any JavaScript variables and object should also be saved in the localStorage or IndexDB where possible. Right now Service Workers are supported in Chrome, Firefox and Opera. Safari and Edge are also working towards adopting them, and we hope that in the future they will be available in every browser.5. App-likeWhen building PWAs, it's counseled to follow a style idea referred to as app-shell design. It sounds terribly sophisticated however basically boils all the way down to this: the app is separated into 2 major components: the shell and also the content. The shell contains all the static UI components like a header, menus, drawers, etc. once we cache associate degree app, the shell should be saved on the device, as a result of we wish it to be on the market in the slightest degree times. That method once a user with no web association opens the app, they will not see associate degree empty screen or a running archosaur - they'll see the cached app interface associate degreed an applicable error message.The content resides within the shell. It can also be cached but it isn't necessary to do so as content is usually dynamic, changes frequently and can be different on every single page load. 6. FreshOnce cached, our PWA will always load from the local storage. However, if we change the service worker sw.js in any way, on the next page load the new version will be downloaded and installed.this.addEventListener('install', function(event) { event.waitUntil( caches.open('v1.0.1').then(function(cache) { // ... }) ); });Using service worker updates we can re-download resources, delete old cache, or completely change the service worker logic. You can learn more about the SW Update process from the Google Developers article. 7. DiscoverableBy adding an online Manifest to our app we are able to give varied info regarding it and alter the manner it's displayed on people's devices. It permits apps to be saved to the house screen with a custom icon, to be started during a separate browser window, and a great deal of different cool stuff.The Web Manifest takes the form of a simple JSON file:manifest.json{ "name": "Progressive Web App: PhotoBooth", "short_name": "PhotoBooth", "description": "Simple Progressive Web App for taking selfies.", "icons": [{ "src": "assets/icons/ic-face.png", "type": "image/png", "sizes": "72x72" }, { "src": "assets/icons/ic-face-large.png", "type": "image/png", "sizes": "144x144 256x256" }], "start_url": "index.html", "display": "standalone", "background_color": "#fff", "theme_color": "#fff", "orientation": "portrait" }Most of the properties are self explanatory so we will cover only the more important ones. See the full Web manifest format and all the available fields.· Shortname - This is the name our app will have when saved to the home screen.· Icons - Array of icons with different resolutions.· Display - Defines how the app will be opened. We've chosen standalone so when started our photo booth will appear in a full-screen window without any browser navigation or menus. It will also be seen as a separate app in multitasking.To register the manifest we have to link it to our HTML:<!-- Web Manifest --> <link rel="manifest" href="manifest.json">Safari doesn't support the Web Manifest standard yet but we can define app-like behavior with this Apple-specific meta tag:<!-- Meta tag for app-like behaviour in iOS --> <meta name=”apple-mobile-web-app-capable” content=”yes”>8. Re-engageablePush notifications are not restricted to native apps to any extent further. because of service employees and also the Push API, internet applications also can send messages to the humanoid notification bar. Not all apps can enjoy having this feature, however once used properly notifications will extremely facilitate interact users. This topic goes on the far side the scope of our tutorial, as Push Notifications area unit quite difficult and merit a full lesson on their own. If you continue to need to implement notifications to your internet app, here area unit a number of the simplest learning resources available: · Google Developers, Push Notifications: Timely, Relevant, and Precise - here.· Google Developers, Push Notifications on the Open Web - here.· MDN, Using the Push API - here.· Push.js, Library that provides a cleaner API for handling push notifications - here.9. InstallableBy default any web site may be manually saved to the house screen victimization the increase Home Screen button from the Chrome browser menu. However, it'd be rather tough to create users "install" our app this fashion, since the majority do not know this feature in the slightest degree. Thankfully, there's how for your app to prompt users to save lots of it with a straightforward installation pop-up. To stop developers from abusing these pop ups, there's not any thanks to programmatically show them. Instead, they'll seem on their own once Associate in Nursing app fulfills a series of requirements:1. There is a valid Web Manifest.2. There is a valid Service Worker installed.3. The app is served over HTTPS.We have all of the above covered, so when a user visits our app's website a couple of times, they will get this prompt:The entire installation process of our app is in this simple prompt. The install happens instantly, and once saved the PhotoBooth will be available to launch from a home screen icon, behaving exactly like a native app.11. LinkableAnyone with an internet browser has access to PWA apps and that they is shared merely via their universal resource locator. No third party tools area unit needed for locating or putting in them.If associate app runs in standalone mode, it is also suggested to feature in-app share buttons, since the browser address bar and menus are not visible.ConclusionOur PWA is now complete. We can test how well it follows the PWA rules with an official Google-made tool called Lighthouse. It recreates possible scenarios and tests the app thoroughly. Here is what it tells us about the PhotoBooth:We passed!If you want to find more PWAs to play with, go to pwa.rocks.
