rollup-cache

Caching utilities for Rollup build plugins. Current version 2.0.0 requires Rollup v3 (breaking change from v1.x which targeted Rollup v2). Provides cacheConfig() and Cache class to persist and reuse expensive computation results across builds, improving incremental build performance. Key differentiator: designed specifically for Rollup plugin ecosystem with cache key generation and invalidation similar to Rollup's own caching. Releases are infrequent; maintenance seems low. Ships TypeScript types. ESM and CommonJS builds available.
