Function CachePut

CachePut<T extends Function = Function>(
options?: CachePutOptions,
): MethodDecorator
Method decorator: always run the method, then write its result to the cache.

Unlike @Cacheable (which short-circuits on a hit), @CachePut executes every time and refreshes the cached value, keeping the cache warm and consistent after a write. If the cache module is not enabled, the method runs normally (graceful no-op).
Type Parameters
- T extends Function = Function
Parameters
- options: CachePutOptions = {}
  key / ttl / tags / store options.
Returns MethodDecorator
A method decorator.
Example
```
class UserService {
  @CachePut({ key: (id) => `user:${id}`, ttl: 600 })
  async update (id: string, data: object) { return await this.save(id, data) }
}
```
