Caching

If you want the implementation flow instead of the reference view, start with Caching Workflow.

Feature activation

nestforge = { version = "1", features = ["cache", "redis"] }

Cache model

Cache support is built around:

• CacheStore
• CachePolicy
• CacheInterceptor

That design makes caching part of the request pipeline instead of a hidden controller behavior.

Define a policy

#[derive(Default, Clone)]
struct UsersCachePolicy;

impl nestforge::CachePolicy for UsersCachePolicy {
    type Store = nestforge::InMemoryRedisStore;
}

Register the interceptor

NestForgeFactory::<AppModule>::create()?
    .use_interceptor::<nestforge::CacheInterceptor<UsersCachePolicy>>();

Default behavior

The built-in defaults are conservative:

• only GET requests are cached
• request URI is used as the cache key
• only successful 200 OK responses are stored

Override policy methods when your application needs custom cache keys, TTL behavior, or cacheability rules.
