One important usage of middleware is to control the application’s flow and logic. Let’s consider a sample user login flow:
- Send
POSTrequest to the server to log in - Save access token in store
- Fetch current user’s profile information

{
type: 'LOGIN',
payload: {
email: 'info@redux-book.com',
password: 'will-never-tell'
