The Story Of Twitter Before PWA Integration

In April 2017, Twitter Lite, the new improvement of its site on the mobile browser, was launched after a collaboration with Google. The name came from the fact that it’s built to be lighter, swifter, and more usable. 

Fast forward to this day, Twitter is the 3rd most popular social media site in the US and the 15th most popular worldwide. Although most of their user demographic is in the US, Japan, and India are the two biggest representatives of Twitter users that exceed the number of US users combined. 

The story of Twitter Lite has to be dated back from 2010 to 2017, with Twitter on its way to becoming the world’s top social media site. 

Twitter had a rough start compared to its biggest rival, Facebook, in the early days. However, from 2010 onwards, the bluebird witnessed a wonderful sight on the chart, a consistent growth quarter by quarter. Between 2015, 2016, and 2017, the growth rate slowed down. 

Recognizing the potential outside of the US, Twitter was quickly reaching out to the international market.

As soon as Google introduced PWA, Twitter knew just how it could expand and acquire new users. Twitter Lite was their final answer, dedicated to emerging countries with unreliable network connections. The new Twitter PWA occupies less than a megabyte of storage while performing with the optimized data-saver mode. Images and videos are in a blurred preview until users click on them.

Nicolas Gallagher, the Engineering Lead at Google for Twitter Lite, stated: “Twitter Lite is now the fastest, least expensive, and most reliable way to use Twitter.” The success of Twitter Lite made headlines for many articles regarding PWA. 

The Solution Of The World’s Largest PWA – Twitter PWA

To assist you with the actional knowledge of PWA development, crucial points about the framework of Twitter PWA, Twitter Lite, and innovative methods customized for on-demand requests will be delivered below. 

Notice that the whole goal of Twitter Lite is to ensure users have an excellent on-site experience, regardless of poor Internet connections, leading to subsequent visits and converting visitors into frequent users. Thanks to the ability to foster speed, reliability, and security of PWA, you can experience it at

Architecture Idea

Twitter Lite, at its core, is a simple, humbly sized Node.js server and an app of client-side JavaScript. PWA will enable the build of API for data caching and storing. The server will first take care of the authentication process, assemble the app’s earliest state, and turn the web codes into interactive pages by initial HTML rendering in the application shell.

Once loaded in the background, data will be requested directly from the Twitter API. The simplicity in this architecture helps Twitter PWA bring forth an outstanding and reliable service in efficiency even at a magnitude scale. 

Designing Performance

Easy to use is one of the top priorities for Twitter Lite. Millions, if not hundreds of millions of users, would access this social network every month. So they want to create a user journey that is highly usable under any connectivity circumstances. 

The developers had utilized a series of incremental performance leverage, the PRPL pattern, combined with the latest updates from modern browsers, to build Service Worker, Web Push Notifications, IndexedDB, and Web App Install Banners. They all were a part of the impressive loading speed and independence from the connection.

Use Of Data

Relying on cached resources to serve smaller data upfront, along with the data-save mode, Twitter Lite is inherently set to minimize the use of data, resulting in a 40% deduction on the timeline page. To load the optimized image on demand, a HEAD request is carried out to display its size with a button click. 

Progressive Loading

After pouring the initial HTML response into the browser, instructions are sent to preload crucial resources for the server to assemble the interactive state. Scripts are shattered into fine pieces using a web pack to load only when asked. 

In other words, the initial load from Twitter Lite is exceptionally fast because only the necessity for the visible view is conducted, while a service worker will precache additional resources to enable the almost instant appearance and smooth transition in future interactions. 

Offline Availablity

Just like its native app, a service worker makes temporary offline usage possible. All the previously loaded pages are re-opened instantly through the caching in the HTML app shell, static assets, and some most common emojis. 

The “Retry” button is provided when there’s a failure in the data or scripts loading to ensure the issue will be taken care of. Simply enabling the offline browsing, the loading speed in the starting up and subsequent visits are much enhanced. 


Forget the expensive rendering work; Twitter Lite was optimized for component rendering. However, the bigger issue lies in the complexity of Tweets with the infinite lists of requirements for additional performance. 

Then they thought of a virtualized list component that only rendered content visible for the view presented above and preserved for scrolling across screens. Another update was through deferring the non-crucial rendering to inactive mode and saving data consumption by the requestIdleCallback API.

Systems And Duplicated Speed

Twitter Lite is a responsive design system built based on component details for the app to conform to any shape requests. Working with UI components cleared space for quick iteration and the reuse of established building blocks. It’s also worth mentioning that the flexbox is heavily relied upon for the design of the layout, limited numbers fixed on colors, font sizes, and lengths.

The Mobile And Desktop Site

Twitter PWA is claimed to get interactive for as soon as 5 seconds and under across most devices with a 3G network. The Lite version loads 30% faster and saves up to 70% of data usage while reducing the time-to-interactive delay by more than 25%.

Compared to the old native app, Twitter PWA only takes up a maximum of 3% of the size, a fraction of space in the device’s storage. Yet it functions profoundly and powerfully. Timelines, one of the most complex features, can be constructed from a limited 30 code configuring lines while attaching a Redux module to a React component, mixed content. 

The PWA works closely resembling the native app, with standard features such as a regular feed, push notification popups, direct messaging, and search tabs. The transition is responsive across pages and elements, although touch response is noticeably reported to be slower than its native apps. The developers are still working on enhancing usability and responsibility in future releases. 

Everything is quite favorable with the desktop version, working well in narrow windows, compared to the old neglected Twitter official apps in both Mac and Windows. The whole experience feels relatively lightweight and relaxed to use. 

Twitter Lite currently supports up to 42 languages, and the Globalize feature was created to emerge the numbers, dates, and messages that fit with the locals.

The Results In Numbers 

  • 65% increase in pages per session
  • 75% increase in the number of Tweets sent
  • 20% decrease in bounce rate

How Did Twitter PWA Become One Of The Fastest PWA?

With the functional tweak in the existing knowledge of service workers, along with the optimization for less data consumption, PWA is hardwired to handle faster-loading speed, and near-instant show-up on subsequent visits, both starting off and during the journey. 

Optimizing for speed isn’t going to be in a day or two, but a repetitive process of testing, tracking, measuring, trying to understand why it’s happening, and applying possible solutions. Work on performance is a vicious cycle of watching, measuring, and improving here and there. 

With that said, Twitter Lite is an accumulation of small improvements and updates over the first-page load, the rendering of React components, preventing re-rendering, and so on. Each catering to the enhancement in performance as a whole, and all the little effort making up to what we see now, one of the world’s largest and fastest PWA adoptions. 

Of course, to maintain that title, developers have to constantly work to ensure everything is in control and evolve the process to something even better if there’s a chance.
