How to Handle Routing in React Class Components with Button Clicks

Routing in React allows you to move between different views in your application seamlessly. If you're using class components in your React application, you might be wondering how to implement routing via button clicks. In this guide, we will explore a straightforward solution to this common challenge.

The Problem: Need for Routing on Button Click

In many React applications, it’s typical to have buttons that navigate users to different views or components. The question arises: How can we achieve this using a button in a class component? The user wants to make a transition to a component named <Display /> when clicking on a button within a class component.

Here’s a typical button setup in React:

While function components have useHistory to manage routing, class components require a different approach.

The Solution: Using withRouter to Inject Routing Props

The good news is that we can use the withRouter higher-order component from React Router to achieve the desired functionality. This method allows us to gain access to the history object as a prop, which we can then use to navigate programmatically.

Step-By-Step Implementation

Here’s how to implement it in your class component:

Import withRouter: First, ensure you import withRouter from the react-router package.

Create the Component: Define your class component and the method that handles the button click.

Use history.push(): Inside the click event handler, use history.push() to navigate to the desired component.

Example Code

Here’s a complete example of how the implementation would look in practice:

Explanation of the Code

Import Statements: We import both React and withRouter at the beginning.

nextBtn Method: This method retrieves the history from props and utilizes history.push() to navigate to the /display route when the button is clicked.

Rendering Button: Instead of wrapping the button in a <Link>, we directly set the onClick handler to handle the routing when clicked. This is efficient and clean.

Conclusion

By following the steps outlined in this guide, you can easily implement routing in your React class components when a button is clicked. The key takeaway is using withRouter to inject the history prop, allowing you to navigate output effortlessly.
