Top 23 JavaScript Performance Projects
-
For example, Fastify removed the instanceof operatorfrom its codebase because it was causing problems for those developers that rely on jest as a testing framework.
-

I've been looking at using japa or ava for web server testing but was curious what others were using and why.
-
lazysizes
High performance and SEO friendly lazy loader for images (responsive and normal), iframes and more, that detects any visibility changes triggered through user interaction, CSS or JavaScript without configuration.
Normally I would write some client-side JS to do this but as this project is solely server-rendered I opted to use a simple tried-and-true library for this: lazysizes.

Project mention: Tips For Building Faster Websites with Efficient CSS Optimisation | dev.to | 2023-08-14
Developers also employ alternative methods for lazy loadings, such as the scroll event listener, besides the Intersection Observer API and the loading property. Unlike the Intersection Observer API, which only monitors the elements targeted for lazy loading, developers attach a scroll event listener to every element on the page. Once the element marked for lazy loading is within the visibility range of the user, a function is invoked to switch the image or video URL with the attribute previously holding it, just like with the Intersection Observer API. This approach is costly for a web project. As the developer seeks to optimise page load by integrating lazy loading to some elements on the webpage, the developer slows down the page's performance due to multiple firing of an event as the function meets each element. Moreover, packages for JavaScript that deal with lazy loading exist. For instance, the LazyLoad library uses the Intersection Observer API, a lightweight JavaScript library. It supports many lazy loading features, such as preloading, responsive image loading, and custom loading animations. Additional lazyloading libraries include Yall.js, Lozad.js, LazyLoad XT for jQuery, and many more.

I actually tried using treesitter and bundlephobia in my first approach before defaulting to the npm module.

three-gpu-pathtracer
Path tracing renderer and utilities for three.js built on top of three-mesh-bvh.
Yeah this is neat but it is 90% not done and that is being generous.
For a open source path tracer with a full glTF compatible material model and lighting and runs in the browser check out:
