Converting Private Route to an ES6 Class in React-Redux: A Step-by-Step Guide

In the world of React and Redux, routing plays a crucial role in creating seamless user experiences. One common requirement is to restrict access to certain routes based on authentication. In this guide, we'll tackle the conversion of a functional Private Route component into an ES6 class component, allowing easier integration with React-Redux.

The Problem at Hand

You might have encountered a common scenario while coding in React where you want to protect routes from unauthorized access. A guide snippet may have introduced you to a function called PrivateRoute that looks like this:

At first glance, you may find the function declaration perplexing, especially when you aim to integrate React-Redux features using higher-order components (HOC). If you are making the leap from functional components to class-based components, understanding the syntax and structure is key.

The Original Code Breakdown

Let’s take a look at the original code snippet of the PrivateRoute function:

Key Points About the Original Code

Destructuring Props: The component takes in props and uses object destructuring to extract the component prop and the rest of the props.

Auth Check: It checks if authTokens are present via a context hook called useAuth.

Conditional Rendering: Based on the presence of tokens, it either renders the specified component or redirects the user to a login page.

Transitioning to ES6 Class Syntax

To convert the above function into an ES6 class component, we will follow a structured approach.

Step 1: Set Up the Class Component

We begin by defining the PrivateRoute class component and extending from React.Component:

Step 2: Implement Conditional Logic

Inside the render() method, implement the logic to either render the route or redirect based on authentication tokens:

Step 3: Map State to Props

To fetch authTokens from the Redux store, we create a mapStateToProps function and connect it to the component:

Conclusion

Converting a functional PrivateRoute into an ES6 class component not only opens new possibilities for integration with Redux but also allows you to manage state and lifecycle methods more efficiently. By following the steps outlined, you should now have a better understanding of both the syntax and the usage of React-Redux in your routing mechanisms.
