linter biome type-checking plugins monorepo

Biome 2.0 beta adds plugins, multi-file linting

GritQL plugins, domain-based rule grouping, and cross-file analysis replace ESLint + typescript-eslint setup, but project scanning adds latency.

Summary

Multi-file linting and type-aware rules (noFloatingPromises) eliminate typescript-eslint overhead; automatic domain detection cuts configuration friction for React/Next projects.

Why it matters

Multi-file linting and type-aware rules (noFloatingPromises) eliminate typescript-eslint overhead; automatic domain detection cuts configuration friction for React/Next projects.

Implementation verdict

Replaces ESLint + typescript-eslint for JS/TS projects. Requires npm install --save-exact @biomejs/biome@beta and pre-release IDE extensions. Worth testing now on non-critical projects; performance regression likely in large repos until scanner optimization lands.
