nestjs-cacheable

A NestJS module for DNS caching with cacheable-lookup. It provides an injectable service exposing a cached DNS lookup function for HTTP clients.

Compatibility

Supports NestJS 11 and 12 in CommonJS and ESM applications. Published JavaScript is CommonJS with TypeScript declarations; ESM applications can use named imports. NestJS 12 requires Node.js 20.19+ (22.12+ on Node 22); Node.js 24 is recommended.
