Async Redux Action

Overview

We have known how the Redux works with Action creators:

  • A Component calls an Action creator.
  • That creator returns an Object with type field.
  • The Component dispatches the Object.
  • Redux store changes.

With Async Redux Action:

  • A Component calls an Action creator.
  • That creator returns a Function instead of an Action object.
  • The Component dispatches the Function.
  • The Function runs. It can have side effects with asynchronous API calls or dispatch Actions.

This Function will get executed by the Redux Thunk middleware from package called redux-thunk.

Redux Thunk

Redux Thunk middleware allows us to write Action creators that return a function instead of an action.
So we can:

  • perform asynchronous dispatch:
    
    const _increment = () => ({
    type: 'INCREMENT'
    });

const increment = () => {
return (dispatch) => {
setTimeout(() => {
dispatch(_increment());
}, 1000);
};
}
