🎉 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 👀

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...

Are we getting PHP in JS? And how is this related to @vite.dev and SSR?

I've taken a look at Rendu, the hypertext preprocessor also used by the upcoming @nitro.build v3

I am looking for a full-time job.

Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me.

If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

We raised a $12.5M Series A round, led by Accel.

In this next stage, VoidZero is accelerating development on both our open-source projects and Vite+, the unified JavaScript toolchain.

This is only the beginning!

In the latest version of @rolldown.rs, JSON imports are tree-shaken!

No more superfluous JSON values in your bundle, only these that you actually access. Without any change of code or config ✨

Interested in the code? Then check out the PR! github.com/rolldown/rol...
First column - title "input". A config.json file with content: { "apiUrl": "https://api.example.com/", "timeout": 5000, "retries": 3, "debug": false } Then an index.js file with the content: import config from './config.json'; console.log(config.apiUrl); Under it the text "Import JSON as usual". Second column - "before". An index.js file that is bundled, with content: //#region config.json var apiUrl = "https://api.example.com/"; var timeout = 5e3; var retries = 3; var debug = false; var config_default = { apiUrl, timeout, retries, debug }; //#endregion //#region index.js console.log(config_default.apiUrl); //#endregion Under it the text "The whole JSON is bundled". Third column - title "after". An index.js file (output) that is bundled, with the following content: //#region config.json var apiUrl = "https://api.example.com/"; //#endregion //#region index.js console.log(apiUrl); //#endregion Under it the text "Only necessary JSON values are included".
