How to Create Two Versions of the Same Component in React JS

As a newcomer to React, you might find yourself in a situation where you need to create a component with distinct versions based on user interaction. For instance, you may want to design a user profile card that behaves differently depending on whether the user has validated their profile or not. This post will guide you through the process of creating two versions of a component efficiently, using state management to toggle between the two states.

The Problem

You are tasked with creating a card component that includes an input field, which should be disabled until the user validates their profile. After validation, the same input field should become enabled. Initially, you might think about creating two separate versions of this input field, but there is a more efficient solution that lets you maintain a single component while still achieving your goals.

The Solution: Using State Management

Instead of setting up two entirely separate components (which can get cumbersome and harder to maintain), you can utilize React's useState hook to manage the state of the input field. This way, you can easily toggle between the enabled and disabled states without duplicating code.

Step-by-Step Implementation

Here’s how to implement this solution:

Set Up State: First, you need a state variable to keep track of whether the profile is validated or not.

Create the Input Field: In your component's return statement, include your input field. Use the disabled attribute, passing the state variable to it. This allows the input field to be dynamically enabled or disabled based on the isValidated state.

Toggle the State: To change the state when the user validates their profile, you can implement a function that updates the isValidated state variable. You might call this function upon a button click or another user event.

Integrate with your component: You can create a button that calls this validateProfile function when clicked.

Customizing CSS and HTML

Now that you have a simple mechanism for toggling the input field's state, you might be wondering how to differentiate the styles for both states. Here’s how you could handle it:

CSS Styling: You can create separate classes for the input field depending on the isValidated state.

CSS Classes: Then in your CSS file, you would have different styles for .enabled-input and .disabled-input.

Conclusion

By managing a single component state using React's useState, you can effectively toggle between different versions of a component without redundancy. This not only makes your code more maintainable but also enhances your application’s performance.
