eslint-monorepo-performance

To optimize ESLint performance in a large TypeScript monorepo, enable caching, adjust concurrency levels, and scope type-aware rules to necessary files. This reduces lint duration bottlenecks and accelerates CI feedback cycles.

ESLint runs slowly in multi-package workloads due to resource-heavy type-aware linting across many packages. Profiling expensive rules, narrowing typed linting scope, and applying content-based cache strategies resolve these performance regressions.

The best cache strategy for monorepo linting involves choosing between content-based or mtime-based caching. Enabling ESLint caching with a suitable concurrency level provides immediate speed improvements for local development and CI jobs.

Yes, explicit tsconfig references are required for typescript-eslint performance tuning. Scoping type-aware rules and ensuring accurate TypeScript configurations prevent expensive rule regressions across multiple packages.

You should narrow the scope of typed linting when lint duration becomes a development bottleneck. Profiling expensive rules allows you to limit type-aware checks to necessary TS files, maintaining lint quality while improving speed.
