Building interactive sites can involve sending JavaScript to your users. Often, too much of it. Have you been on a mobile page that looked like it had loaded only to tap on a link or tried to scroll…
The goal of bringing basic, decentralised payments to the masses remains outstanding due to Hard scaling problems. These problems are rooted in the mechanics of consensus algorithms and fundamental limits in our ability to shuttle data around a global network.
Preload is a new web standard aimed at improving performance and providing more granular loading control to web developers. It gives developers the ability to **define custom loading** logic without suffering the performance penalty that script-based resource loaders incur. A few weeks ago, I shipped preload support in Chrome Canary, and barring unexpected bugs it will hit Chrome stable in mid-April. But what is that preload thing? What does it do? And how can it help you?
gpu.js is a single-file JavaScript library for GPGPU in the browser. gpu.js will automatically compile specially written JavaScript functions into shader language and run them on the GPU using the WebGL API. In the case where WebGL is not available, the functions will still run in regular JavaScript.
Once we were over the infamous Haskell learning-curve, we began looking for functional programming, immutability, and types everywhere! Given that one-third of our code runs in the browser (via Angular v1 — for now!), it is only a matter of time before we make the switch to typed-FP for front-end development as well.
React is slow - just like other frontend frameworks. But if you care about performance, it's fairly easy to make any React application super fast. Here is how.
React is usually pretty fast, but it’s easy to make small mistakes that lead to performance issues. Slow component mounts, deep component trees, and unnecessary render cycles can quickly add up to an…
Writing inefficient React components can cause them to rerender too often. Peter Bengtsson looks at ways of creating and optimizing stateless components.
Rendering a list of some elements in a page is a common task for almost any web-app. In this post I would like to show how to improve performance for that case. For a test example we will create app…
Service workers are at the core of Progressive Web Apps. They allow caching of resources and push notifications, which are two of the main distinguishing features that have set native apps apart up…
gpu.js is a GPGPU(General purpose Programming on Graphical Processing Units) library that lets you hand over hefty calculations to the GPU for super fast operation and output. It currently runs on the browser and node.js, wherein it is using WebGl API’s in the browser, and a single threaded operation on node.js. OpenCL is on the roadmap.
Lately I’ve been asked a lot about how I would implement a debounce function as an exercise, and I wondered why this question has become prevalent in the front-end engineering world. The more I was…
It’s quite common to divide our program into chunks using functions which we can call later to perform some useful action. Sometimes, a function can become expensive to call multiple times (say, a…
Thanks to mobile device and network proliferation, more people are using the web than ever before. As this user base grows, performance is more important than ever. In this article, find out why performance matters, and learn what you can do to make the web faster for everyone.
