Fixing match.params.id with the useEffect Hook in React Router v6

When working with React Router v6, developers often encounter issues, especially when trying to extract route parameters. A common problem arises when trying to access match.params.id, resulting in blank pages or unexpected behaviors in React applications. If you’ve faced this dilemma, you’re not alone. In this post, we’ll explore how to effectively fix this issue using the useEffect hook and the useParams function for a smoother experience in your React projects.

The Problem

Imagine you've written some code in your React application that attempts to access the id from the route parameters. This is commonly done using a prop called match, but in React Router v6, this method has changed. The absence of the match prop can lead to confusion and, situations where your application renders a blank page instead of the expected profile data.

Here’s a snippet of the original code that leads to the issue:

With this implementation, the match prop is not available in React Router v6, causing the application to malfunction.

The Solution: Using useParams Hook

To rectify this situation, you should utilize the useParams hook provided by react-router-dom. This hook allows you to easily access the route parameters, thus resolving the issue effectively. Below are the steps to implement this solution.

Step-by-Step Guide

Import the useParams Hook: The first step is to import the useParams hook from react-router-dom. This is crucial for accessing the route parameters directly.
