Use with Redux Promise Actions

Last updated 3 months ago

To use this middleware with redux-promise-middleware-actions, invoke createAsyncAction and return a promise from the payload creator.

import { createAsyncAction } from 'redux-promise-middleware-actions';
// Create an async action
const fooAction = createAsyncAction('FOO', async (url) => {
const response = await fetch(url);
return response.json();
});
// Use async action
dispatch(fooAction('https://some.url'));

This would dispatch FOO_PENDING and FOO_FULFILLED with the data as the payload. fooAction has a reference to these action creators on the object itself, e.g. fooAction.pending(). You can listen for these in the reducer like this:

const reducer = (state, action) => {
switch (action.type) {
case String(fooAction.pending):
return {
...state,
pending: true,
};
case String(fooAction.fulfilled):
return {
...state,
data: action.payload,
error: undefined,
pending: false,
};
case String(fooAction.rejected):
return {
...state,
error: action.payload,
pending: false,
};
default:
return state;
}
};
