  • Making my TypeScript types 15.7 faster
    I used to use ts-expect for this, but I migrated to Vitest's type-testing utils (expectTypeOf, above) to drop a dependency. Either way, I already had the tests, and I'll admit they really earned their keep. A type optimization can quietly turn { a: string } into { a?: string } and nothing throws. The tests are what catch that. - Source: dev.to / 19 days ago
  • 7 Free Tools for Testing AI-Generated Code Before It Ships
    Vitest is a newer testing framework designed specifically for projects using Vite as a build tool. If your project already uses Vite, Vitest is worth knowing about because its test runner is significantly faster than Jest's in that context. - Source: dev.to / 2 months ago
  • Three Ways to Convert JSON to TypeScript. Only One Is Deterministic.

  • oxlint-tailwindcss: the linting plugin Tailwind v4 needed
    The project runs entirely on the VoidZero tool ecosystem. Tsdown for the build, oxfmt for formatting, vitest for testing, tsgo (native TypeScript 7 in Go) for type checking, and of course oxlint for linting the plugin itself. Every tool in the chain is built on Rust or optimized for speed. - Source: dev.to / 3 months ago
  • VoidZero is driving the unification of the Javascript ecosystem
    VoidZero launch week is drawing to a close, and the world of Javascript development has just been given a significant boost. If you follow developments in build tools, youโ€™ll know that fragmentation is rife, and that itโ€™s difficult to stay at the cutting edge without using the best tool for each task.
