Advanced Redux Patterns

Redux Middleware

Middleware functions are powerful tools for handling side effects in Redux applications. They sit between actions and reducers, allowing you to intercept and modify actions.

Redux Thunk

Redux Thunk is a middleware that allows you to return functions from action creators instead of objects. This is useful for async operations.

const myAction = (param) => (dispatch) => {
  dispatch(actionStart());
  setTimeout(() => {
    dispatch(actionSuccess(param));
  }, 1000);
};

Redux Saga

Redux Saga is an alternative middleware for handling side effects using generator functions. It provides more advanced control over asynchronous operations.

Best Practices

• Keep actions pure and side-effect free
• Use middleware for async operations
• Structure your reducers properly
• Use selector functions to access state
