redux-promise with Axios, and how do deal with errors?

Question

So, I see on an error, redux-promise hands me back error: true, along with the payload, but that is once it hits the reducer... to me, decoupling the request AND error condi

Answer 1

The accepted answer doesn't make use of redux-promise. Since the question is actually about handling errors using redux-promise I provide another answer.

In the reducer you should inspect the existence of the error attribute on the action object:

// This is the reducer
export default function(previousState = null, action) {
  if (action.error) {
    action.type = 'HANDLE_XHR_ERROR'; // change the type
  }  
  switch(action.type) {
    ...

And change the type of the action, triggering a state change for an error handling component that you have set up for this.
