Node.js URL.toJSON() Method

Last Updated : 11 Apr, 2023

The url.toJSON() method in the node.js URL module is used to return the serialized URL of the URL object. The return value of this method is equivalent to the URL.href and url.toString() methods. If an URL object is serialized using JSON.stringify() method then it is called automatically.

Syntax:

url.toJSON()

Parameters: This method does not accept any parameters.

Return Value: This method returns the serialized URL of the URL object.

Example 1: The below examples illustrate the url.toJSON() method in Node.js:

javascript

// node program to demonstrate the
// url.toJSON() method in node.js
 
// Require an URL module
const url = require('url');
 
// Creating and initializing myURL variable
let urls = [
    new URL('https://www.geeksforgeeks.com'),
    new URL('https://www.google.com'),
    new URL('https://www.mygeeks.com')
];
 
// Display result
console.log(JSON.stringify(urls));

Output:

[
    "https://www.geeksforgeeks.org/",
    "https://www.google.com/",
    "https://www.mygeeks.com/"
]

Example 2: The below examples illustrate the url.toJSON() method in Node.js:

javascript

// node program to demonstrate the
// url.toJSON() method in node.js
 
// Require an URL module
const url = require('url');
 
// Creating and initializing myURL variable
let myurl = [
    new URL('https://www.geeksforgeeks.org'),
    new URL('https://write.geeksforgeeks.org'),
    new URL('https://www.practice.geeksforgeeks.org'),
    new URL('https://www.demo.geeksforgeeks.org'),
    new URL('https://write.geeksforgeeks.org'),
];
 
// Display result
console.log(JSON.stringify(myurl));

Output:

[
    "https://www.geeksforgeeks.org/",
    "https://write.geeksforgeeks.org/",
    "https://www.practice.geeksforgeeks.org/",
    "https://www.demo.geeksforgeeks.org/",
    "https://write.geeksforgeeks.org/"
]

Note: The above program will compile and run by using the node index.js command.
