🎉 Excited to announce that I'm joining VoidZero as DevRel!

As I was following the project from early on, I couldn't say no to the chance when @evanyou.me reached out.

I can't wait to share all the incredible things lined up for @rolldown.rs, OXC, @vite.dev, and @vitest.dev 👀

Ever since we announced Vite+, the excitement, and the questions, have been rolling in.
We took some time to answer the most common ones and also added them at the end of the Vite+ announcement post.

Instead of providing your tsconfig manually in @rolldown.rs, you can now enable @vite.dev like automatic resolution.

◇ Finds the nearest tsconfig.json
◇ Respected by both, resolver and transformer
◇ tsconfig references will be searched as well (given certain criteria are fulfilled)

Want to speed up subsequent @vitest.dev runs?
Then try out the new experimental file-system based cache ✨

⋄ Caches transformed modules
⋄ Does *not* work with browser mode yet
⋄ Can be manually cleared via `vitest --clearCache`

More in the docs
vitest.dev/config/exper...
Vitest’s Experimental FS Cache Enable via CLI or config: `pnpm vitest --experimental.fsModuleCache` First run does not change timings. There is no cache yet! An image with statistics about the test run with 3088 tests passed and 6.17s testing duration, transform taking 5.32s, setup 461ms and collect 18.50s. Subsequent runs use the file system cache, reducing transform times Another statistics image. The subsequent run now takes only 5.14s, with transform time down to 673ms, setup to 341ms and collection time down to 13.20s

Improved require(esm) interop in @rolldown.rs.

Since the last beta, the bundler supports the special `as "module.exports"` keyword and aligns with the @nodejs.org behavior.

Another step towards better interoperability between CJS and ESM, now with bundler support!
Title: Improved require(esm) support Subtext: chunk.mjs defines the return value when used via require by setting it via export `as “module.exports"` Image showing that index.js requires chunk.mjs and logs result: const User = require('./chunk.mjs'); console.log('User:', User); The chunk exports a user class by default, but also via "export { User as 'module.exports' }". --- Screenshot of the a previous Rolldown version showing the console.log that does not log the class but an object with default and 'mode.exports' key. Subtitle: OLD: Use literal exports, no transformation Screenshot of the latest Rolldown version correctly logging that User is a class. Subtitle: NEW: Detection & correct runtime result Three bullet points at the end: * More predictable behavior * Aligns with Node.js * Only relevant for require(esm)

Having a hard time to get a URL for your (relative) assets after bundling?
Then you will enjoy the experimental `resolveNewUrlToAsset` option that is available in @rolldown.rs.

All you need to do is to activate it, and all `new URL('./path/to/file', import.meta.url)` calls will be updated.
Three column layout. First column: "Input" shows an index.ts with the following content ```js const url = new URL('./styles.css', import.meta.url) console.log(url) ``` It also shows a styles.css but its content is not important. Subtitle: Code to get a reliable URL to a local asset Runs everywhere, right? Second column: "Before" index.js: ```js //#region index.ts const url = new URL("./styles.css", import.meta.url); console.log(url); //#endregion ``` Shows a mismatch between the "./styles.css" url and the bundled "./styles-DvhEFzjT.css" tab that is also included in the column. Subtitle: MISMATCH - After bundling, URL does not contain the updated asset name with the file hash. Last column: After Shows a rolldown.config.ts that enables `experimental.resolveNewUrlToAsset`. Then, shows an index.js that now has the right reference to the bundled css file, "assets/styles-CjdrdY7X.css": ```js const url = new URL("assets/styles-CjdrdY7X.css", import.meta.url); console.log(url); ``` Subtitle: With the experimental option, relative assets are now referred to correctly ✅

Oxlint enabling type checking straight out of tsgo!

This should speed up the slow `tsc --noEmit` step in large repos.

Vitest 4.0.11 adds an experimental `fsModuleCache` flag to cache module transforms between reruns. Learn more: vitest.dev/config/exper...

This is an opt-in feature, please let us know how it works for you!

And example of a single test file that imports a lot of files (~1500). Almost a 50% boost!

Did you know that you can match against Standard Schemas in @vitest.dev?

With the release of Vitest 4, this is possible now. No matter if you want to match your whole data or only partials against a schema and no matter which validation library is used as long as they support Standard Schema
Title: Match against Standard Schema in Vitest Code ```js import { it, expect } from "vitest"; import * as v from "valibot"; import * as z from "zod"; const schema = v.object({ name: v.string(), age: v.number(), email: v.pipe(v.string(), v.email()), }); it("should match the schema", () => { const user = { name: "Jane Doe", age: 42, email: "youshoulduse@vitest.dev", }; // Validate the entire object expect(user).toEqual(expect.schemaMatching(schema)); // Also works for validating partial data expect(user).toEqual({ name: 'Jane Doe', age: 42, email: expect.schemaMatching(z.string()), }); }); ``` Result when running Vitest: Test passing.

🚀 @rolldown.rs now enables `output.minifyInternalExports` by default.

This feature shortens internal export names by using the `as` keyword.
At first glance your bundle may look bigger...
…but the additional `as` unlocks improved minification.
Input: index.js with "import ./constants.js", constants.js with "import('./dynamic.js'); export const theAnswer = 42;", dynamic.js with "import { theAnswer } from './constants.js'; console.log(theAnswer);". Subtitle: Exported variable used by a dynamic chunk "internally". Before: Bundled code, as well as bundled & minified code. After minifcation you see that "theAnswer" is preserved in the bundle. Subtitle: When minified, exported variable names are persisted as-is, leading to bigger bundles. After: "as" naming for export and import ("export { theAnswer as t }", "import { t as theAnswer }". When minified, the names are minified too. Subtitle: Added named exports lead to better minification and smaller bundles.

SvelteKit 3 / Vite 8 will be built on rolldown. You can use it now if you're adventurous!

If you're not using the new remote functions, it largely works without issue and is much faster.

We'd love help in discovering any bugs that haven't been unearthed yet! Post them at github.com/vitejs/rolld...
