Node.js URLSearchParams.sort()

The sort() method in URLSearchParams is a built-in method in Node.js that sorts the parameters of a URL according to their keys. This method can be very useful in situations where you need to compare or filter URLs, as it makes it easier to look for specific parameters and their values.

Syntax

The syntax for using the sort() method is as follows:

searchParams.sort();

This method sorts the parameters of the searchParams object according to their keys.

Example

The following example shows how to use the sort() method with URLSearchParams:

const url = new URL('http://www.example.com/?c=3&a=1&b=2');
const searchParams = url.searchParams;

searchParams.sort();

console.log(url.toString()); 
// output: 'http://www.example.com/?a=1&b=2&c=3'

In this example, we create a new URL object that contains three parameters: c=3, a=1, and b=2. We then use the sort() method to sort the parameters according to their keys. Finally, we print out the sorted URL using the toString() method.

Notes

• The sort() method does not modify the original searchParams object. Instead, it creates a new instance of URLSearchParams with the sorted parameters.
• The sort() method sorts the keys in ascending order by default. To sort in descending order, you can pass a callback function as an argument.

Conclusion

The sort() method in URLSearchParams is a useful tool for manipulating and filtering URLs in Node.js applications. Its ability to sort parameters according to their keys can help make your code more efficient and easier to read.
