Reading Query Parameters in Node.js
The query parameter is the variable whose value is passed in the URL in the form of key-value pair at the end of the URL after a question mark (?). For example, www.geeksforgeeks.org?name=abc where, ‘name’ is the key of query parameter whose value is ‘abc’.
We just create a folder and add a file as index.js. To run this file you need to run the following command.
Steps to run the program:
- The project structure will look like this:
- Make sure you have installed ‘view engine’ like I have used ‘ejs’ and install express module using the following commands:
npm install express npm install ejs
- Run index.js file using below command:
- Open browser and type this URL “http://localhost:3000/user?name=raj&age=20” as shown below:
- Go back to console and you can see the Query parameters key, value as shown below:
So this is how you can read Query parameters in Node.js.
