How to use axios / AJAX with redux-thunk
I guess you shouldn't (or at least not supposed to) put the promise directly at the store:
export function FetchWeather(city) { let url = `${API_URL}&q=${city},in`; let promise = axios.get(url); return { type: types.FETCH_WEATHER, payload: promise };}This way you are not even using redux-thunk, because it's returning a plain object. Actually, redux-thunk, enables you to return a function that will be evaluated later, for example, something like this:
export function FetchWeather(city) { let url = `${API_URL}&q=${city},in`; return function (dispatch) { axios.get(url) .then((response) => dispatch({ type: types.FETCH_WEATHER_SUCCESS, data: response.data })).catch((response) => dispatch({ type: types.FETCH_WEATHER_FAILURE, error: response.error })) }}Be sure to properly setup the redux-thunk middleware. I really recommend reading redux-thunk documentation and this amazing article to have a deeper understanding.
