The current boundary between sync and async lands is at Route#dispatch
(in the route-component branch). Routes use this method to update their state when the URL changes. It's nice to keep this boundary at a low level so it doesn't permeate the rest of the API. For example, the URLStore
would need to know about promises in order to make Router.transitionTo
return a promise.
Anyway, the best we could do would be to return a promise that resolves immediately after the call to route.setState
, which doesn't necessarily mean that changes have been made to the DOM.
Would it be too much hassle to ask people to use componentDidMount
and/or componentDidUpdate
in their tests? If people absolutely need to know when a transition
is completed, maybe we could provide a didTransitionTo
transition hook?
from react-router.
When integration testing you'll need to know exactly when you can start asserting the screen has the data you expect.
from react-router.
Right. Seems like that's exactly what componentDidUpdate
is for.
from react-router.
depending on the app's architecture, couldn't componentDidUpdate fire multiple times before a single 'transition' is over?
from react-router.
For integration tests we will need some sort of hooks to know that transitions and when data from #57 have landed before making assertions.
We should have some test helpers for this.
from react-router.
The hook you're looking for is Route#dispatch
. That method returns a promise that resolves when the transition is complete and the ActiveStore
has been updated.
from react-router.
closing for a different converstaion
