Vite 8.0 is out!
Vite 8.0 is out! March 12, 2026 We're thrilled to announce the stable release of Vite 8! When Vite first launched, we made a pragmatic bet on two bundlers: esbuild for speed during development, and Rollup for optimized production builds. That bet served us well for years. We're very grateful to the Rollup and esbuild maintainers. Vite wouldn't have succeeded without them. Today, it resolves into
Inside Turbopack: Building Faster by Building Less
Back to BlogTuesday, January 20th 2026 Inside Turbopack: Building Faster by Building LessPosted by Edit. Save. Refresh. Wait… Wait… Wait… Compiling code usually means waiting, but Turbopack makes iteration loops fast with caching and incremental computation. Not every modern bundler uses an incremental approach, and that’s with good reason. Incremental computation can introduce significant complex
Announcing Rolldown 1.0 RC
Today we are thrilled to announce the Release Candidate for Rolldown 1.0. TL;DR: Rolldown is a JavaScript/TypeScript bundler written in Rust. It is 10-30x faster than Rollup while maintaining compatibility with Rollup's plugin API. This RC marks API stability. No breaking changes are planned before 1.0. We encourage you to test it on your projects and report any issues. Using Vite? Try Rolldown to
JavaScript scope hoisting is broken
7/6/2025 Most modern JavaScript bundlers implement an optimization called "scope hoisting". The idea is that rather than wrapping each bundled module in a function, a compiler concatenates the modules into a single scope. Say you have a program like this: // index.js import {add} from './math'; console.log(add(2, 3)); // math.js export function add(a, b) { return a + b; } When scope hoisted, the o
How We Reduced CKEditor’s Bundle Size by 40% | CKEditor
In this article, we’ll show how we cut CKEditor 5’s bundle size by 40% through tree-shaking and bundle size optimization techniques and share tricks you can use to slim down your own JavaScript libraries. We’ll also walk through the tools and processes we used to achieve this, measure improvements, and catch regressions. As any software library author will tell you, building and maintaining is har
Rolldown | Rust bundler for JavaScript
Why do we still need bundlers? Skipping the build step is impractical With the general availability of native ES modules and HTTP/2 in modern browsers, some developers are advocating for an unbundled approach for shipping web applications, even in production. While this approach works for smaller applications, in our opinion bundling is still very much necessary if you are shipping anything non-

Release v0.21.0 · evanw/esbuild
This release doesn't contain any deliberately-breaking changes. However, it contains a very complex new feature and while all of esbuild's tests pass, I would not be surprised if an important edge case turns out to be broken. So I'm releasing this as a breaking change release to avoid causing any trouble. As usual, make sure to test your code when you upgrade. Implement the JavaScript decorators p
