How to Access URL Parameters in ReactJS
⭕ Overview
In this tutorial, I'm excited to demonstrate how to access URL parameters in a React application, a crucial skill for creating dynamic web pages that respond to user input and navigation changes.
We'll focus on a common scenario where a user might click an "Edit" button on a website, and you need to retrieve a unique identifier (ID) from the URL to fetch and display the correct data. I'll walk you through setting up a React component to handle URL parameters using React Router, explaining how to capture these parameters and use them to perform operations like fetching data from a server or filtering a list.
By implementing this functionality, your React applications will become more interactive and user-friendly, providing a smooth experience as users navigate through different parts of your application and interact with individual elements.
This session is designed to enhance your React development skills by adding practical knowledge that can be applied in various web development projects.

React Router version 6 introduces several powerful new features which include a few breaking changes from version 5. Below are two changes that you will need to adhere to if you're running version 6.
(1) The Switch component has been replaced with a new Routes component. You'll need to convert all your Switch elements to Routes.
(2) A new element property replaces the render property/function. Thus passing URL parameters to class components can still be done using a Wrapper function component. Function components retrieve URL parameters in the usual way using Hooks.
Examples on how to retrieve URL parameters in either stateless or stateful components using React Router 6 can be found on my GitHub Repo below.
