#react js web application development services

Vanilla JS is great until you have to start using it in real life world. Here are some examples of what's really important when working on highly scalable web applications

Maintainbility

Debuggability

A/B testing

Understnding customer needs

Issue investigations and gradual rollouts

Design decisions - cost vs revenue analysis

Monetization

and many many others

As you can see I have barely touched the actual JS framework to be used. While technical decisions do matter, pushing Vanilla JS because you are unable to fathom the breath of challenges faced by services like Twitter, just speaks about your shortcomings.

There is a reason Node.js has become popular for backend development instead of devs whipping out their own V8 based JS runtimes. There are more important shit to be dealth with. React will work just fine and spending inordinate amount of time deciding which frontend JS framework to use ends up becoming nothing more than bikeshedding.

How we wrote our own Service Worker

As we continue the process of reinvigorating Tumblr's frontend web development, we're always on the lookout for modern web technologies, especially ones that make our mobile site feel faster and more native. You could have guessed that we are making the mobile dashboard into a progressive app when we open-sourced our webpack plugin to make web app manifests back in August. And you would've been right. But to make a high quality progressive web app, you need more than just a web app manifest—you also need a service worker.

What is a service worker?

A service worker is a helper script that a page registers with the browser. After it is registered (some people like to also call it "installed"), the browser periodically checks the script for changes. If any part of the script contents changes, the browser reinstalls the updated script.

Service workers are most commonly used to intercept browser fetches and do various things with them. https://serviceworke.rs has a lot of great ideas about what you can do with service workers, with code examples. We decided to use our service worker to cache some JS, CSS, and font assets when it is installed, and to respond with those assets when the browser fetches any of them.

Using a service worker to precache assets

You might be wondering "why would you want to pre-cache assets when the service worker is installed? Isn't that the same thing that the browser cache does?" While the browser cache does cache assets after they're requested, our service worker can cache assets before they're requested. This greatly speeds up parts of the page that we load in asynchronously, like the notes popover, or blogs that you tap into from the mobile dashboard.

While there are open-source projects that generate service workers to pre-cache your assets (like, for example, sw-precache), we chose to build our own service worker. When I started this project, I didn't have any idea what service workers were, and I wanted to learn all about them. And what better way to learn about service workers than building one?

How our service worker is built

Because the service worker needs to know about all of the JS, CSS, and font assets in order to pre-cache them, we build a piece of the service worker during our build phase. This part of the service worker changes whenever our assets are updated. During the build step, we take a list of all of the assets that are output, filter them down into just the ones we want to pre-cache, and write them out to an array in a JS file that we call sw.js.

That service worker file importScripts()'s a separate file that contains all of our service worker functionality. All of the service worker functionality is built separately and written in TypeScript, but the file that contains all of our assets is plain JavaScript.

We decided to serve our service worker directly from our node.js app. Our other assets are served using CDNs. Because our CDN servers are often geographically closer to our users, our assets load faster from there than they do from our app. Using CDNs also keeps simple, asset-transfer traffic away from our app, which gives us space us to do more complicated things (like rendering your dashboard with React).

To keep asset traffic that reaches our app to a minimum, we tell our CDNs not to check back for updates to our assets for a long time. This is sometimes referred to as caching with a long TTL (time to live). As we know, cache-invalidation is a tough computer science problem, so we generate unique filenames based on the asset contents each time we build our assets. That way, when we request the new asset, we know that we're going to get it because we use the new file name.

Because the browser wants to check back in with the service worker script to see if there are any changes, caching it in our CDNs is not a good fit. We would have to figure out how to do cache invalidation for that file, but none of the other assets. By serving that file directly from our node.js application, we get some additional asset-transfer traffic to our application but we think it's worth it because it avoids all of the issues with caching.

How does it pre-cache assets?

When the service worker is installed, it compares the asset list in sw.js to the list of assets that it has in its cache. If an asset is in the cache, but not listed in sw.js, the asset gets deleted from the cache. If an asset is in sw.js, but not in the service worker cache, we download and cache it. If an asset is in sw.js and in the cache, it hasn't changed, so we don't need to do anything.

// in sw.js

self.ASSETS = [

  'main.js',

  'notes-popover.js',

  'favorit.woff'

];

// in service-worker.ts

self.addEventListener('install', install);

const install = event => event.waitUntil(

  caches.open('tumblr-service-worker-cache')

    .then(cache => {

      const currentAssetList = self.ASSETS;

      const oldAssets = /* Instead of writing our own array diffing, we use lodash's */;

      const newAssets = /* differenceBy() to figure out which assets are old and new */;

      return Promise.all([ ...oldAssets.map(oldAsset => cache.delete(oldAsset)), cache.addAll(newAssets)]);

  });

);

We launched 🚀

Earlier this month, we launched the service worker to all users of our mobile web dashboard. Our performance instrumentation initially found a small performance regression, but we fixed it. Now our mobile web dashboard load time is about the same as before, but asynchronous bundles on the page load much faster.

We fixed the performance regression by improving performance of the service worker cache. Initially, we naively opened the service worker cache for every request. But now we only open the cache once, when the service worker starts running. Once the cache is opened, we attach listeners for fetch requests, and those closures capture the open cache in their scope.

// before

self.addEventListener('fetch', handleFetch);

const handleFetch = event =>

  event.respondWith(

    caches.open('tumblr-service-worker-cache')

      .then(cache => cache.match(request)

      .then(cacheMatch => cacheMatch

        ? Promise.resolve(cacheMatch)

        : fetch(event.request)

      )

    )

  );

// now

caches.open('tumblr-service-worker-cache')

  .then(cache =>

    self.addEventListener('fetch', handleFetch(cache));

const handleFetch = openCache => event =>

  event.respondWith(

    openCache.match(request)

      .then(cacheMatch => cacheMatch

        ? Promise.resolve(cacheMatch)

        : fetch(event.request)

      )

  );

Future plans

We have lots of future plans to make the service worker even better than it is now. In addition to pre-emptive caching, we would also like to do reactive caching, like the browser cache does. Every time an asset is requested that we do not already have in our cache, we could cache it. That will help keep the service worker cache fresh between installations.

We would also like to try building an API cache in our service worker, so that users can view some stale content while they're waiting for new content to load. We could also leverage this cache if we built a service-worker-based offline mode. If you have any interest in service workers or ideas about how Tumblr could use them in the future, we would love to have you on our team.

Why Ionic Hybrid network becoming more popular day by day

Introduction of Ionic Framework

Ionic is a complete open-source SDK for hybrid mobile app development created by Max Lynch, Ben Sperry and Adam Bradley of Drifty Co. in 2013. Ionic is world’s most popular cross platform mobile development technology. Basically it’s hybrid mobile app development framework. Using Apache Cordova, it can be easily run on mobiles. A big advantage of using Ionic is that the code base remains the same for all mobile platforms and the UI/UX looks like a native mobile platform. The good news is: if you can manage to create websites, you already know how to build mobile apps. Ionic Framework offers the best web and native app components for building highly interactive native and progressive web apps. It is the only mobile app stack which allows developers to design apps for all app stores and the mobile web, using an unique code base. Moreover, Ionic’s Platform Continuity guarantees your app will look superb on every single device. Ionic provides tools and services for developing hybrid mobile apps using Web technologies like CSS, HTML5, and Sass. Apps can be built with these Web technologies and then distributed through native app stores to be installed on devices by leveraging Cordova.

Benefits of Ionic Framework

Platform Independent Framework- Ionic can recognize the platform specific advanced CSS proportional to the native look and feel on different mobile operating systems. It reduces the requirement for code changing as it gives the codes of mobile-optimized HTML, JS, and CSS components. Apart from this, ionic integrates into Angular JS which becomes a robust structure making code excellent as well as more manageable. This empowers the Start-up entrepreneurs to come out with newer concepts at reduced budget.

Cross-Platform Mobile App Development with Ionic- Building an application without a moment's delay is essential, and it should be compatible with all mobile devices. However, it needs extremely limited use of time, assets and efforts, and helps in giving a unified look and feel. Besides, Ionic helps with building applications quickly and with expertise, and deploys standard tools with a solitary code base.

Default User Interface- Ionic has many default CSS and JS parts that cover the vast majority of the basic things you need to make a mobile application. . Apart from regular ones like buttons and navigation it also includes form inputs, lists, cards, sliding boxes and many more. These can be easily customized by adding CSS classes to the element. The default styles are basic, smooth, and you can without a doubt redo them by adding pre-defined CSS classes to the component.

Based on AngularJS- If you’ve worked upon Ionic, and then you would likely realize that it is developed on top of the Angular JS framework. The extensions to HTML's sentence structure offered by AngularJS are extremely useful for mobile app designers. The Ionic structure utilizes AngularJS to offer a bunch of center functionalities to the designer with the goal that they can incorporate alluring components into the application.  AngularJS is an ideal approach to make program based applications, while with the assistance of the Ionic structure, versatile designers can make hybrid applications and web applications.

Utilizes Cordova Plugins- Plugins play an essential part in Ionic application development. Modules are coded in JavaScript and come appended to the application. Ionic framework application development utilizes Cordova plugins to help designers in accessing different components of the versatile framework- for example, camera, GPS, and so on. According to your business and offered administrations, mobile app developers can utilize any of these modules to build their ideal mobile application.

There are a few good reasons to go with Ionic, depending on what you would be using it for:

1. Ionic use Angular’s MV* paradigm: If you are a web developer and want to be able to compete in the mobile space Ionic is great for you. Ionic uses HTML and CSS to lay out its views, so not only will you have all of the power of CSS transitions and canvas drawing, but you will also feel at home with the DOM. If you’ve ever used Angular in production, this will be doubly true for you, because the logic layers of Ionic use Angular’s MV* paradigm.

2.Desktop support: Ionic has added a flexible grid, and split-pane type features, allowing you to build mobile-first apps with responsive desktop layouts.

3.Open Web Standards: To paraphrase one of their founders, you’re betting on the open web, rather than getting stuck learning single-platform technologies that don’t carry over. (e.g. Learning CSS and DOM layouts versus Xcode’s autolayout)

4.Progressive Web Apps: This is a big trend on Google and Ionic’s radar, and it seems like Ionic is uniquely positioned to let you build app-class web experiences that can also be published in the App Store.

5.If you are bootstrapping a start-up and want to cut development time and cost by leveraging existing skill sets, Ionic is one of the best choices. Ionic creates apps for iOS, Android and Windows. It has default CSS that changes between versions for a Native experience. And all this can be done in JavaScript which is one of the most common programming languages known by developers now because of its ubiquity on the web. There are other frameworks around now that can achieve this in different languages, but most of them are not as popular or have as much support. So unless you have a specific reason you need to use python, Ruby, C++, Java etc. stick with Ionic or React Native in JavaScript or Xamarin in C#. Those are the most mature communities for cross-platform apps.

6. If you are new to web/mobile development the skills you will learn making things with Ionic will take you a lot further than what you will get with native. JavaScript is everywhere. It is more popular than Swift, and more importantly, it can be used for a lot more things. Java is really popular as well, but in my opinion, JavaScript seems to be slowly taking over Java’s position in the web development world. Companies that were built on java will stick around for a long time, but many new ones are being built on stuff like JavaScript, Ruby, Go and the like. And yes that list will be different in a few years, but Java will not be making it back on, and JavaScript will be the longest lasting one that is around for now.

7.Ionic Community: There’s a community of over 30,000 members on the Ionic forum, an active Slack Channel, and Ionic is the 45th or so most popular/starred repo on Github.

How to Install Ionic Framework

Make sure you have an up-to-date version of Node.js installed on your machine. If you don't have Node.js installed.

Open the command prompt and verify the Node.js version by using the command node -v.

To install Cordova and Ionic, use - npm install -g cordova ionic.

Make sure to install the latest version of JDK and Android Studio IDE for Android development.

To create a new project, use - ionic start projectname template.

Inside the project folder, you can add Android/iOS platform based on your development using the command - ionic cordova platform add android.

After these code changes are done, you can generate the required .apk file with the command - ionic cordova build android.

Once the .apk file is generated successfully, you deploy the file on a real device and do the testing, or you can test it as a web application using a browser.

To run it in a browser, use - ionic serve.

To run it on a device, use - ionic Cordova run android -device.

Finally, play with Ionic!
