# react-hooks ESLint plugin rules are extremely slow, dominating lint time - React version: `react@19.2.3` - `eslint-plugin-react-hooks` version: `eslint-plugin-react-hooks@7.0.1` - `eslint` version: `eslint@9.39.1` ## Steps To Reproduce 1. Install `eslint-plugin-react-hooks` (the React Compiler ESLint plugin) 2. Enable the recommended plugin rules: e.g. `reactHooksPlugin.configs.flat.recommended, jstsFiles` 3. Run ESLint with `TIMING=50` on a large codebase (~15k+ files) 4. Observe that `react-hooks/static-components` takes 42-56% of total lint time ## Link to code example Unfortunately, we cannot share a minimal reproduction as this occurs on a large proprietary codebase. However, the performance data should be reproducible on any sufficiently large React codebase. ## The current behavior When running ESLint with the `TIMING` flag on our codebase, the `react-hooks` plugin rules dominate lint time: ``` Rule | Time (ms) | Relative :------------------------------------------|-----------:|--------: react-hooks/static-components | 393394.236 | 56.2% unused-imports/no-unused-imports | 62579.162 | 8.9% redos-detector/no-unsafe-regex | 35114.790 | 5.0% import/named | 24641.617 | 3.5% react-hooks/rules-of-hooks | 16596.903 | 2.4% ... ``` **Key findings:** - `react-hooks/static-components` takes **~393 seconds** (6.5 minutes) — more than **5x longer** than the next slowest rule - The react-hooks plugin nearly **doubles total lint time**: ~3 minutes without the plugin vs ~6 minutes with it enabled - With 4x parallelism (`--concurrency=4`), total ESLint time goes from ~190 seconds to ~370 seconds when the plugin is enabled - Even if we disable `react-hooks/static-components`, another rule jumps up to take the top spot. It seems to trigger from the plugin itself, not any particular rule. ## The expected behavior The `react-hooks` rules …
