ApiMethod with async

[mmaquevice]

Congrats for RPC ! :)

Are you planning to support async api method ?

e.g. :

@ApiMethod(path: 'myPath')
MyResponse get(String id) async {
...
}

@mmaquevice your MyRespose type is really a Future<SomeClass> since you are creating an async function. RPC already support returning futures and since in Dart you can't distinguish a sync function that returns a Future<A>, from an async function that "returns" an A, then you already have this functionality.

My bad, I thought it didn't work but you're right!

The problem with this is that you can't use the await keyword. I have an api method that does a request to a separate back-end server (i.e. elastic search) and would like to wait for the response before returning. Is there a work around for this?

[Kleak]

you can use await just add async on the function declaration

class TestResponse {
  int result;
}

@ApiMethod(name: 'test upload', path: 'test', method: 'GET')
Future<TestResponse> test() async {
  int number = await new Future.value(12);
  return new TestResponse()..result = number;
}

How does this work from the client? You can't really have a Future of a Future.. can you?

[Kleak]

on the client side there is no difference.

[jkriesel]

Within the client api, the client api returns a future already. You'd end up with Future of a Future

[Kleak]

No just a future
