URL Query Params in React.js and Next.js 13: A Comprehensive Tutorial

URL query parameters provide a powerful way to pass and retrieve data within a URL. In web development, they are commonly used to transmit information between different pages or components. React.js and Next.js are popular JavaScript frameworks for building user interfaces and server-side rendering, respectively. In this tutorial, we will explore how to work with URL query parameters in both React.js and Next.js applications.

Prerequisites
To follow along with this tutorial, you should have a basic understanding of React.js and Next.js, as well as a development environment set up for either framework.
React.js Solution

In React.js, we can access URL query parameters using the URLSearchParams API, which allows us to retrieve and manipulate the query string portion of a URL.

Here's an example of how to use URL query parameters in a React.js component:

import React from 'react';

const Component = () => {
    const searchParams = new URLSearchParams(document.location.search);

    return (
        <div>
            Tutorial: {searchParams.get('tutorial')}
        </div>
    );
};

export default Component;

In the code above, we create a new instance of URLSearchParams with document.location.search, which represents the query string portion of the current URL. We can then use the get method of URLSearchParams to retrieve the value of a specific query parameter, in this case, 'tutorial'. The component renders the retrieved value within a div element.

Next.js 13 Solution

Next.js is a framework that simplifies server-side rendering and provides an integrated routing system. To work with URL query parameters in Next.js, we can utilize the built-in URL and URLSearchParams APIs.

Consider the following code snippet to access URL query parameters in a Next.js application:

const url = new URL(request.url);
const searchParams = new URLSearchParams(url.search);
const skip = searchParams.get("skip"); // Retrieves the value of the 'skip' parameter
const limit = searchParams.get("limit"); // Retrieves the value of the 'limit' parameter

console.log(skip);
console.log(limit);

It uses the URL and URLSearchParams APIs to parse the query string portion of the URL and retrieve the values of the 'skip' and 'limit' parameters.
You can use this solution inside your server components.
