What is Redux Saga?

Redux Saga is a wise and powerful wizard for managing complex tasks in your React and Redux app. It specializes in handling asynchronous operations, like fetching data or dealing with side effects, making your code more organized and your app’s behavior smoother. Think of it as a magical assistant that takes care of tricky tasks in the background, ensuring everything runs harmoniously.

We will discuss about the following parameters of Redux Saga in React:

Real-Life Example:

Suppose you are building an ecommerce website with React and Redux. When users visit your website, add products to their cart, and proceed to checkout, you might want to apply a coupon code. In this scenario, React Saga would come into play to handle the asynchronous operation of applying the coupon code, coordinating the process seamlessly with the Redux state management.

Key Features Of Redux Saga:

• Sagas: These are the function that manage the flow of async operation. They listen certain action and perfrom those action based on those action or task.
• Middleware: Redux Saga works as middleware in your Redux store, intercepting the action before they react hte reducers.
• Generators: Redux Saga utilise the javascript generators, making it easy to handle asynchronous operation in a synchronous looking way.

Advantages of Redux Saga:

• Async Operation: Redux Saga makes your code well organised. It handle the async operation in a synchronous-looking way.
• Easy Testing: Writing test for your async code make difficulties or cmplexity in your code, but Redux Saga makes it easy to test the code. You can test each step in your Sagas seperately.
• Concurrency: Handling multple async opertaions is concurrently is simplified. Saga allow you to handle async operations more precisely.
• Error Handling: Error handling is straightforward with Redux Saga. You can catch errors at each step, preventing your app from crashing.

Disadvantages of Redux Saga:

• Learning Curve: For Beginers, Redux Saga might be a bit complex. It introduce new concept, and understand how generators work can take time.
• Complexity for Simple Cases: If your app doesn’t have many complex async operations, using Redux Saga might be overkill. It could add unnecessary complexity to your code.
