Apollo-client: Response Wrapper

Created on 20 Jun 2016 · 7Comments · Source: apollographql/apollo-client

Is there way to somehow wrap responses from graphql server? I want to know if server returned 401 or refreshed token.

For instance your network interface allows to applyMiddleware to work with request object. It would be nice if I could apply middleware to response, and have something like general error check.

networkInterface.use([{ applyMiddleware(res, next) { if (!res.status===401) { dispatch(logout()); } next(); } }]);

Therefore I wouldn't need to write same code for every query and mutation response.

Can you explain a bit more what you mean by this? For example, a hypothetical code snippet of what you would like to do? I'm not quite sure what wrapping a response would mean.

@pfulop Yes! 🙌 I was just searching the docs for a way to to this. It could be something like an afterware applicable after fetch return the result promise on networkInterface - line 142

Use cases:

logout user
remove expired tokens
handle errors & redirects

networkInterface.use([{
  applyAfterware(result, next) {

    if (result.status === 401) {
      logout()

      // or
      // localStorage.removeItem("token")
      // temporarilyPopupError(result.error.message)
      // redirectToSignInPage()
    }

    next()
  }
}])
