Standard patterns to follow for creating custom middleware
When creating custom middleware for Redux, there are several standard patterns you can follow. These patterns allow you to create side effects for actions, modify or cancel actions, or modify the input accepted by dispatch. Here are some standard patterns for middleware:
- Creating Side Effects: Middleware can create side effects for actions by intercepting them before they reach reducers, allowing for tasks like logging, dispatching additional actions, or handling asynchronous operations.
- Modifying or Canceling Actions: Middleware can modify actions before they reach reducers, such as adding metadata or modifying payload data. It can also cancel actions altogether based on certain conditions.
- Modifying Input Accepted by Dispatch: Middleware can modify the input accepted by dispatch, enabling tasks like throttling or debouncing actions, or transforming data before it’s dispatched.
Writing Custom middlewares in React Redux
Custom middleware in React Redux is like having a helper that can do things with actions before they’re handled by our app. It allows us to intercept actions and apply custom logic before they reach the reducers. In this article, we are going to discuss how it is done.
