ServiceWorker: Revolution of the Web Platform

While not the most amusingly named feature of the web platform, everything seems to point at ServiceWorker being the most significant addition to the web platform since the introduction of AJAX – over 10 years ago. Not to be confused with WebWorker (used to offload intense compute operations onto another execution thread), ServiceWorker allows you to intercept (and hijack) network requests originating from your site before they’re even dispatched. This article explores how it works, what it means and what it enables, and how you can implement it by following a case study.

Parallaxin' - HTML5 Rocks

by 1 other
Whether or not you like parallaxing sites is one thing, but what you can say pretty confidently is that they’re a black hole of performance. The reason for this is that browsers tend to be optimized for the case where new content appears at the top or bottom of the screen when you scroll (depending on your scroll direction) and, in general terms, the browsers work best when very little changes visually during a scroll. For a parallax site that’s rarely the case since many times large visual elements all over the page change, causing the browser to do a repaint of the whole page.

Using web workers - Document Object Model (DOM) | MDN

Dedicated Web Workers provide a simple means for web content to run scripts in background threads.  Once created, a worker can send messages to the spawning task by posting messages to an event handler specified by the creator. The worker thread can perform tasks without interfering with the user interface.  In addition, they can perform I/O using XMLHttpRequest (although the responseXML  and channel attributes are always null).

Lazy Load Plugin for jQuery

by 10 others
Lazy Load is a jQuery plugin written in JavaScript. It delays loading of images in long web pages. Images outside of viewport (visible part of web page) wont be loaded before user scrolls to them. This is opposite of image preloading. Using Lazy Load on long web pages containing many large images makes the page load faster. Browser will be in ready state after loading visible images. In some cases it can also help to reduce server load.

Mozilla : du Webkit et de l'accélération graphique dans Firefox - PC INpact


Au premier plan de la concurrence entre les navigateurs, on trouve le chapitre des performances. Devenues un passage obligé dans tous les tests de ce type de produits, elles sont un élément comparatif crucial pour séparer le bon grain de l’ivraie. Dans ce domaine, certaines brillent davantage que d’autres et Firefox, que ses extensions ont rendu célèbre, doit être bousculé pour s’adapter. Mozilla prépare donc notamment une nouvelle machine JavaScript et va chercher son inspiration ailleurs.
