Oxlint and Oxfmt Cut a React Project's Lint Check From One Minute to Two Seconds

The Oxc project's linter Oxlint and formatter Oxfmt claim to run dramatically faster than ESLint and Prettier. To test this, the author timed both setups on Excalidraw, a 710-file open-source React and TypeScript codebase, on an ordinary laptop. The full check dropped from about 60 seconds to roughly 2 seconds, a real but smaller speedup of around 30x rather than the advertised 50 to 100x. Oxlint also reported 435 warnings where ESLint reported none, but most were stricter default rules rather than genuine bugs, though it did surface some useful React issues. The author notes that three custom Excalidraw rules have no direct Oxlint equivalent, and suggests the real work is reviewing which rules to keep.
