How to Handle Routing in React After Axios Response: A Step-by-Step Guide

When working with React applications, one common challenge developers face is appropriately managing page routing, especially after fetching data from an API with libraries like Axios. A frequent scenario is trying to navigate to a different page after receiving a successful response from an Axios request. In this guide, we'll walk you through how to achieve this seamlessly while implementing best practices for routing with react-router-dom.

The Problem at Hand

You may have encountered a situation where your Axios request returns a boolean value indicating success, but you are unsure how to navigate the user to a new page based on that response. Here’s a quick overview of a common use case:

You have a sign-in form that sends credentials to a backend using Axios.

Upon receiving a true response (indicating successful authentication), you want to redirect the user to the Home page of your application.

However, due to the structure of your React component, directly returning a component isn't effective for navigation.

Example Scenario

Here's an excerpt from a sample sign-in component:

As you can see, the method is meant to handle form submission, but we need to add logic to handle page redirection based on the response.

The Solution: Using history.push()

Instead of trying to return a new component directly from the handleSubmit function, you can utilize the useHistory hook from react-router-dom. This allows for programmatically navigating to different routes in your application.

Step-by-Step Implementation

Import useHistory: First, ensure you import the useHistory hook from react-router-dom at the top of your component.

Initialize history: Next, invoke useHistory within your component to access the history object.

Modify handleSubmit Function: Now, update the handleSubmit function to use history.push('/') when the response indicates a successful login:

Handling the Response: In this updated function, if demo is true, it logs a success message and invokes history.push('/') to redirect the user to the home page. If the authentication fails, you handle that gracefully, perhaps notifying the user of incorrect credentials.

Additional Considerations

User Feedback: Consider providing user feedback when login fails, same as how you're handling successful responses. This could enhance the user experience significantly.

Security Practices: Ensure your Axios requests handle sensitive data appropriately, especially when dealing with authentication and user sessions.

Conclusion

Managing routing in a React application based on Axios responses can be efficiently handled with react-router-dom. By using the history.push() method, you can redirect users to new pages without attempting to return components directly from your asynchronous functions. This approach streamlines user navigation and helps maintain a smooth user experience.
