library0.8.0jsnpmunverified

Vite plugin that allows ESLint to run in the browser by bundling ESLint with browser-compatible polyfills. v0.8.0 supports ESLint 8-10 and Vite >=4, Node >=20. Differentiates from other ESLint plugins by targeting browser environments for linting, not build-time checks. Ships ESM-only, uses rolldown as bundler. Notable for breaking changes: dropped Node 19 support in v0.8.0 and switched to rolldown in v0.6.0. Community-maintained by ota-meshi.

fix
Ensure compatibility with rolldown; report issues if unexpected behavior occurs

breakingv0.5.0 changed cwd path to '/' which may break ESLint rules relying on working directory
fix
Adapt rules to use absolute paths or handle '/' cwd
affects: >=0.5.0
gotchaThis plugin does NOT run ESLint during build; it allows ESLint imports in browser runtime
fix
Use for browser-based linting, not build-time checks
