Services API

Import path: @sdcorejs/nestjs/services

This entrypoint provides two infrastructure services:

• Cache — memory/Redis backends, resilient cache-aside service and scoped handler caching.
• HTTP client — Axios methods with exact-origin context-header propagation and redirect revalidation.

import {
  CacheService,
  HttpService,
  type CacheConfig,
  type HttpClientConfig,
} from '@sdcorejs/nestjs/services';

Both modules are global after forRoot, including when composed by SdCoreModule. Caching is fail-soft at the backend boundary. Identity propagation is fail-closed: no origin is trusted by default, configured identity headers are stripped from untrusted destinations, and every redirect is evaluated again.

Cache interceptor registration

@Cached() requires CacheInterceptor on the handler/controller or an APP_INTERCEPTOR registration. Providing CacheModule alone does not execute decorator behavior.
