Redux Documentation

Middleware -

Provides a third party extension point between dispatching an action and the moment it reaches the reducer.

In Primero V2, we have used the following Middlewares:

1. Thunk Middleware -

Thunk middleware allows you to write action creators that return a function instead of an action. The thunk can be used to delay the dispatch of an action, or to dispatch only if a certain condition is met.

2. Router Middleware

Keeps the location of router in sync with redux

3. Redux Devtools

Developer Tools to power-up Redux development workflow or any other architecture which handles the state change

4. Logger

Logs the previous state, action and the new state in the app whenever a new action is fired

We also have Three Custom middleware

Redux provides with API called applyMiddleware which allows us to use custom middleware

1. restMiddleware

  • Rest Middleware decides if Data fetched from API has been cached or not.

2. offlineMiddleware

  • Offline caching of redux store

3. authMiddleware

  • Ensures user is authenticated before accessing the app

Reducers

Reducers specify how the application's state changes in response to actions sent to the store.
