What’s New in ViteLand: July 2025 Recap

Welcome to another edition of What’s new in ViteLand! Every month, we recap the project updates for Vite, Vitest, Oxc, Rolldown and what’s happening in our community.

What’s Vite+? ​

The Vite Ecosystem will gather in Amsterdam on October 9-10 for the first-ever in-person ViteConf. We had 3 incredible ViteConf online editions, and we can’t wait to meet in real life.

It’s also where we’ll be dropping all the details about Vite+. Be the first to discover what it is and how it can improve your team’s DX.

There’s a packed lineup of speakers, including Eric Simons, CEO of Bolt.new/StackBlitz, and Mathias Biilmann, CEO of Netlify. We’ll be discussing the future of web development through topics like next-generation tooling, agent experience, and more.

Not to mention the world premiere of CultRepo’s Vite Documentary. The never-before-told backstory of Vite. Featuring the Vite Team and authors of Svelte, Solid, Astro, and more. If you want a sneak peek, check out the trailer that just got released.

Stay tuned.

Project Updates ​

Vite ​

• Vite 7 is out with continued Environment API developments, including the new buildApp hook to let plugins coordinate the building of environments. Vite also bumps up their required Node version, as Node.js 18 has reached EOL. This also means that Vite is now shipped as ESM-only package. So, no excuse not to do the same for your own libraries!
• Are you on the Vite Land Discord already? If not, you should join now and get your official Vite Discord server tag and mingle with like-minded devs.
• For the first time in history, Vite's weekly downloads surpassed the one's of Webpack. Who would've expected that 5 years ago when Vite started as a side project?

Rolldown ​

• Rolldown-Vite supports tsconfig path resolution out of the box. Use the path resolutions defined in your tsconfig by setting resolve.tsconfigPaths. No extra plugin needed anymore!
• Using Yarn Plug-and-Play? Then you'll be happy to hear that Rolldown supports it out of the box now! No need to use nodeLinker: node-modules anymore.
• vite-plugin-node-polyfills got an update which ensures that it will use Rolldown's built-in features if it runs via rolldown-vite, yielding better performance while not compromising on compatibility.
• Rolldown now allows you to transform your top level variables to var. Sounds like legacy code? Not really. This can lead to better performance if you have a lot of top-level variables that are not used until later in the code. The downside: It doesn't work well with circular references, which is why it is opt-in.
• Can't get enough of the speed improvements? Thanks to some in-depth JavaScript engine optimization trickery, Rolldown's startup time decreased by 2.1x. This leads to a faster Time to Interactive, better cold-starts for serverless and also benefits your dev server startup speed.

Oxc ​

• Type-aware linting comes to Oxlint! The result of collaboration between the Oxc team and @auvred from the typescript-eslint team. Type-aware rules, such as no-floating-promise can be fully covered and integrated like other Oxlint rules for a great DX. The upcoming first version will include two rules to start with. The following next version will then include all type-aware rules from typescript-eslint. The best news: No slowdown was experienced when it was tested within large repositories such as the VS Code repo.
• JS custom rules, with an API that aims to be ESLint compatible. We invested heavily into the underlying implementation to make it fast without the typical data-passing drawback of JS-in-native plugins. The first prototype looks promising, but more testing is needed before we can release it.
• Multiple minor versions of Oxlint were released. These include newly ported rules, additional auto-fixers, dozens of bug fixes and the ground work for custom JS plugins as mentioned above.

Vitest ​

• Visual Regression Testing is now available in the latest Vitest beta! This means you can now write tests that compare screenshots of your components, ensuring that visual changes are intentional and not accidental without any extra tools! This wouldn't be possible without Vitest's browser mode.
• Talking about @vitest/browser: The experimental feature reached the milestone of 1 million weekly NPM downloads, while simplifying developer setups around the world. Time to make it stable? Soon™

From the Community ​

• We’re excited to officially welcome Brooklyn, the creator of napi-rs, onboard the VoidZero team. Big things to come. Did we mention Vite+?
• Speaking of which, NAPI-RS releases v3 with a safer API design and new cross-compilation features. A major improvement for the underlying bridge between Rust and JavaScript.
• Linear has been migrating to rolldown-vite over the last few months with production builds taking only 13 seconds to bundle >10K modules.
• The Linear team followed up a few weeks later saying their production build times further decreased to 7 seconds thanks to Oxc supporting styled components.
• The Endform team wrote about JavaScript tools are being rewritten in Rust. Like how Endform uses Oxc for dependency analysis in their CLI.
• Jökull Sólberg compares the differing approaches for type-aware lint rules between Biome and Oxlint.
• Node.js started using Rolldown to generate API docs. In their own words, “I mean, it’s blazingly fast, we just couldn’t not use it 😃”.
• Outline switched from vite to rolldown-vite and build times got 22.3x faster. One of the largest build performance improvements we’ve seen so far.
• Posthog migrated from ESLint to Oxlint and the PR title says it all. While the linting is now 33x faster linting, type-aware linting was not available back then in Oxlint. Without the overhead, the gains are still 5-7x.
• Vercube switched from ESLint to Oxlint for 10x linting speed boost, but this is without type-aware linting as well. Luckily, it comes to Oxlint soon.
• Run-async replaces JSHint with Oxlint after 11 years. Just skipping over ESLint entirely is something you don’t see every day.
• The Angular team is switching to Rolldown for their experimental chunk optimization feature, which allows better control of the emitted JavaScript files than their esbuild-based setup. Maybe it is just a matter of time that this will be replaced by Rolldown too?
• Vue Router will use tsdown as build tool for its next version. This unlocks fast builds and shorter CI times!
• Better T Stack adds Oxlint as an option! Now you can choose fast linting when scaffolding your next project with it.
