Redux middleware to perform api calls reducing action creators boilerplate
This is a slight modification of the example found in Redux docs.
Install
$ npm install @georapbox/redux-call-api-middleware
Usage
After passing it once to applyMiddleware(...middlewares), you can write all your API-calling action creators the following way:
export function loadPosts(userId) {
return {
// Types of actions to emit before and after (required)
types: {
requestType: 'LOAD_POSTS_REQUEST',
successType: 'LOAD_POSTS_SUCCESS',
failureType: 'LOAD_POSTS_FAILURE'
},
// Check the cache (optional); defaults to `() => true`
shouldCallAPI: state => !state.posts[userId],
// Perform the fetching (required)
callAPI: (dispatch, state) => fetch(`http://myapi.com/users/${userId}/posts`),
// Arguments to inject in begin/end actions (optional); defaults to `{}`
payload: { userId },
// Callback function to be executed after `requestType` is dispatched (optional); defaults to `() => {}`
onRequestDispatched: (payload, dispatch, state) => {
// Do something when `requestType` is dispatched
},
// Callback function to be executed after `successType` is dispatched (optional); defaults to `() => {}`
onSuccessDispatched: (response, payload, dispatch, state) => {
// Do something when `successType` is dispatched
},
// Callback function to be executed after `failureType` is dispatched (optional); defaults to `() => {}`
onFailureDispatched: (error, payload, dispatch, state) => {
// Do something when `failureType` is dispatched
}
}
}
