Function idempotency

idempotency(options?: ServerIdempotencyOptions): Middleware
Server-side idempotency middleware.

Reads the x-idempotency-key header from mutating requests. If a response has already been stored for that key, it is returned immediately — the handler is never called. Otherwise the handler executes and its response is stored for future replays.

GET, HEAD, and OPTIONS requests pass through without checking.
Parameters
- options: ServerIdempotencyOptions = {}
  Configuration.
Returns Middleware
A server-side Middleware.
Example
```
server.handle(CreateTodo, createHandler, {
    middlewares: [idempotency({ ttl: 86_400_000 })]
});
```
