Framer needed better chunking to speed up their customers' large websites. They partnered with us to integrate @rolldown.rs and fine-tune its `advancedChunks` feature

The Result: @framer.com reduced the LCP by a massive 41% for bigger websites!

If you write JS or TS, many tools you use are being rewritten in Rust. While Rust offers speed, it might limit our control over tools. In this talk, I’ll explore how Oxc (#Vite compiler) balances #Rust #performance with #javascript plugin customization

First of these optimizations rolled out in v1.15.0 with a reduced scope. Next version of oxlint will be even faster: github.com/oxc-project/...

On my laptop: ~15% faster on `oven-sh/bun`, ~9% faster on `microsoft/vscode`, ~11% faster on `posthog/posthog`, and ~8% faster on `elastic/kibana`

Vitest 4 runs simple test files faster! You can already check it out by installing Vitest 4 beta. On average, Vitest now takes 25% less time to start the test. Due to parallelisation, the overall time difference can vary.

We are focusing our efforts on improving the time even more in the next beta!

A benchmark showing that vitest-beta is 1.17 ± 0.01 times faster than Vitest 3. On average, the beta version takes 710ms and Vitest 3 takes 833ms.

Trying some new oxlint optimizations. This PR has gone over several iterations in the last few months and the core idea is simple: don't run rules for files if they don't apply (using an AST node bitset lookup).

The result: linting is around 15% faster in practice.

Oxlint linter CodSpeed benchmark showing 65-84% performance improvements

A hyperfine CLI benchmark showing that linting the vscode repository is around 17% faster.

Type-aware linting is a fast-moving space with multiple experimental approaches, several recent changes, and potentially confusing names.

This is a well-written article that describes Oxc's approach and helps clarify the overall landscape 👍

we're making typescript-go faster for tsgolint!

optimizing the tsconfig file registry has yielded a 52x perf improvement when benchmarking against affine and we've got more on the way:

`oxlint --type-aware`. Mic drop.

It's incomplete and have numerous problems, including a noticeable performance issue.

BUT, you can finally see your floating promises quickly!

I agree that the direction to bet on ts-go seems better. In any case, I'm excited for fast type-aware linting:

Faster Type-Aware Lint Rules: Biome vs. Oxlint

ESLint and TypeScript-ESLint are indispensable. Their type-aware rules—no-floating-promises, the entire no-unsafe-* family, and dozens more—have become the back
