How to Fix Conditional Rendering Issues in React with Firebase Authentication

Conditional rendering is a powerful feature in React, but it can sometimes lead to confusion, especially when dealing with real-time data from services like Firebase. If you're encountering issues with conditional rendering in your code, particularly in verifying a user's mobile number, you’re not alone! Let’s delve into this common problem and uncover an effective solution.

Understanding the Problem

You’re building a simple mobile number verification feature in your React application using Firebase. The goal is to check if a user's phone number matches a specific number—if it does, you want to display "Verified"; if not, "Not Verified." However, despite your best efforts, the conditional rendering you've implemented doesn’t seem to work as expected.

Here's a snippet of what you initially tried:

While this logic seems sound, it may not operate correctly due to timing issues with the user object, which is fetched asynchronously. Let's explore an organized solution to this issue.

Solution Overview

To make conditional rendering work correctly with Firebase Authentication, follow these steps:

Set Up State for Verification:

Use the React state to manage the verification status.

Use useEffect for Side Effects:

This hook will allow us to react to changes in the user object and execute the verification logic.

Step 1: Initialize Verification State

First, create a state variable to hold the verification status.

Step 2: Implement the useEffect Hook

Next, use the useEffect hook to check the user's phone number each time the user state changes. Here’s how you can do it:

Step 3: Update Your Return Statement

Now, you need to display the value of the verified state instead of the static conditional operator. Update the JSX as follows:

Conclusion

By following these organized steps, you can effectively manage conditional rendering in your React app using Firebase Authentication. Keep in mind that the asynchronous nature of authentication services means you often need to manage state carefully to ensure your UI reflects the accurate verification status.

Now that you have a clearer approach, we hope this guide will help you solve your conditional rendering issues efficiently. Happy coding!
