Rust and the Future of Systems Programming
There’s been a lot of excitement and news recently about Project Quantum and Mozilla’s efforts to build the next generation of web browser technology. One of the major components of Project Quantum is leveraging the innovations of the Servo web engine and the Rust programming language, both run by vibrant open source communities and sponsored by Mozilla. At Mozilla, we expect Rust to play a huge r
Sign-in on the Web — Credential Management API and Best Practices
This is a recollection of my part of the talk at Chrome Dev Summit 2016 titled “Sign-in on the Web — Credential Management and Best Practices”. Check the video for my colleague Sabine Borsay taking the first half of the talk describing the unique challenges we face on the web when personalizing user’s experience through sign-ins. Unlike native apps, the web needs considerations for different attac
Using Electrode to Improve React Server Side Render Performance By Up To 70%
We built Electrode, the react/node.js application platform that powers walmart.com with several goals in mind, including ease of use, re-usability of components across applications and, most importantly, performance. We use server side rendering for almost all of our applications for two reasons: Improved performance for the customerBetter for SEOIn our tests, however, we found that React’s render
Choosing GraphQL to build Drift’s messaging platform
Drift is building the customer messaging platform for businesses to communicate with prospects and customers from their own website or application. Like most internet companies today, we built our platform starting from a RESTful JSON API. But even with a clean slate, we still ran into familiar challenges that all API developers face: schema definition and introspection, versioning, paging, data a
Progressive Web Apps with React.js: Part 2 — Page Load Performance
Ensure Page load performance is fastMobile web speeds matter. On average, faster experiences lead to 70% longer sessions and 2 x more mobile ad revenue. Investments in web perf saw the React-based, Flipkart Lite triple time-on-site, GQ get an 80% increase in traffic, Trainline make an additional 11M in yearly revenue and Instagram increase impressions by 33%.

Progressive Web Apps with React.js: Part I — Introduction
There’s much new in the world of Progressive Web Apps (PWAs) and you might be wondering how compatible they are with existing architectures using libraries like React and JS module bundlers like Webpack. Does a PWA require a wholesale rewrite? What web performance metrics do you need to keep an eye on? In this series of posts I’ll share my experience turning React-based web apps into PWAs. We’ll a
Vue 2.0 is Here!
Today I am thrilled to announce the official release of Vue.js 2.0: Ghost in the Shell. After 8 alphas, 8 betas and 8 rcs (a total coincidence!), Vue.js 2.0 is ready for production! The official guide has been fully updated and is available at vuejs.org/guide. Ever since the work on 2.0 started back in April, the core team has made significant contributions to API design, bug fixes, documentation
How to safely use React context
Context is a very powerful feature in React, with lots of disclaimers around it. A bit like the forbidden fruit in paradise. That should be enough to keep you far away from context right? Well of course not, it is a (unsupported) React feature, and forbidden features will be used for the mere fact that they exist! Context makes it possible to pass data to components deep in the component tree with

Where do I put my business logic in a React-Redux application?
This is a question that we have all struggled with in building applications. It is an important question because it influences the architecture of our code and how well our app will absorb new features and complexity as it naturally grows during its lifetime. TL;DR (Summary)There are many approaches that will work but it is important to understand the tradeoffs to pick the best solution. I discuss
You Might Not Need Redux
People often choose Redux before they need it. “What if our app doesn’t scale without it?” Later, developers frown at the indirection Redux introduced to their code. “Why do I have to touch three files to get a simple feature working?” Why indeed! People blame Redux, React, functional programming, immutability, and many other things for their woes, and I understand them. It is natural to compare R
Generators and Channels in JavaScript
IntroductionThe following should be an introduction into generators and channels. If you know about promises, generators, coroutines and channels jump to the Using Generators and Channels with React section. While the examples might not be suited for the real world, it should be seen as a starting point, to experiment with the possibilities that might arise by taking this approach. Just think abou
Webpack 2 Tree Shaking Configuration
Tree Shaking, a modern dead code elimination algorithm for ECMAScript 2015+ is one of the most anticipated features in Webpack 2. By eliminating unused ES6 exports, Webpack can further help the minification process to get your bundle much smaller than ever before. Update 11/14/2016: Webpack 2 sample application code has been updated to match the most recent updates in Webpack (v2.2), React (v15.4)
