Adding support for timeout would be nice, or a function you could dispatch exported by redux-catch.

Fetching some data with xhr here

This looks like a really useful tool for catching and logging errors inside reducers.

I'm just wondering if it breaks convention massively if the errorHandler function were able to dispatch an action that the app could pick up - like displaying a warning, or so on?

Something along the lines of this:

import reduxCatch from 'redux-catch';
const errorHandler = (error, getState, dispatch, lastAction) => {
    console.error(error);
    dispatch({
        type: APP_UNKNOWN_ERROR,
        payload: {
            lastAction
        }
    });
};
const middleware = [reduxCatch(errorHandler)];
return createStore(
    rootReducer,
    initialState,
    compose(
        applyMiddleware(...middleware),
    )
); 

Thanks for writing this middleware!

Is it possible to catch the error which is thrown by an Async API? If so, Please provide an example.
