Redirecting Users After Login in React JS

As a beginner in React JS, you might find yourself facing challenges when trying to implement features commonly found in web applications, such as redirecting users after they log in. One common issue is figuring out how to navigate users to a new page (like /users) when their login is successful and error-free. Fear not! In this guide, we will walk you through the solution step by step.

Understanding the Problem

When users fill in their login credentials and submit the form, your app needs to determine if the credentials are valid. If they are, you should successfully redirect the user to a different route in your application—say, the /users path. The issue arises when you are unsure how to handle the redirection in React properly.

Typical Approach

Many beginners try to use the <Redirect /> component immediately inside the onSubmit function like this:

However, this does not work as expected because <Redirect> is a JSX construct and doesn’t trigger a re-render outside the normal component render flow.

The Solution: Using useHistory Hook

To resolve this issue, we can use the useHistory hook from react-router-dom. This hook allows us to programmatically navigate users to a different URL in a clean and effective manner.

Steps to Implement the Solution

Import useHistory: Begin by importing the useHistory hook in your ValidationLog.js file.

Initialize history: Call useHistory() inside your ValidationLog component to gain access to the history instance.

Update the onSubmit Handler: Modify your onSubmit function to use the history.push() method to redirect to the desired path after login.

Conclusion

Redirecting users effectively in a React application can seem challenging at first, but with the help of the useHistory hook from the react-router-dom, the process becomes intuitive and straightforward. Implementing this feature allows you to enhance your application's user experience significantly.

By following the structured steps outlined in this post, you're now equipped to handle user redirection successfully after login. Happy coding!
