How to ignore global cache on some routes in NestJs

Question

I activate the global cache by APP_INTERCEPTOR in my NestJS app. But now, I need to ignore it on some routes. How can I do that?

A different take on what Sadra suggested, instead of the trackBy() method you can override the isRequestCacheable() method on the CacheInterceptor class. It is a little easier.

@Injectable()
export class CustomCacheInterceptor extends CacheInterceptor {

  excludePaths = ["/my/custom/route"];

  isRequestCacheable(context: ExecutionContext): boolean {
    const req = context.switchToHttp().getRequest();
    return (
      this.allowedMethods.includes(req.method) &&
      !this.excludePaths.includes(req.url)
    );
  }
}
