Node.js URLSearchParams.getAll()

Last Updated : 10 Aug, 2026

The URLSearchParams.getAll() method in Node.js is used to get all values associated with a specific key in a URL’s query string. It is helpful when the same parameter appears more than once.

  • It is useful for repeated query parameters.
  • It keeps the values in the same order as they appear.

Syntax:

urlSearchParams.getAll(name)

Where

  • urlSearchParams: An instance of the URLSearchParams class that stores query parameters.
  • getAll(name): A method that returns all values linked to the given parameter name.

Return Value: An array containing all values for the specified key. If the key is not found, it returns an empty array.

Example 1:

javascript 
let url = new URL('https://example.com/?par=5&bar=2'); 
let params = new URLSearchParams(url.search.slice(1)); 

//Add a second par parameter. 
params.append('par', 4);

console.log(params.getAll('par'))'

Output:

['5', '4']

Example 2:

javascript 
let url = new URL('https://example.com/?par=5&bar=2&bar=7&par=4&bar=9'); 
let params = new URLSearchParams(url.search.slice(1)); 

console.log(params.getAll('bar'));

Output:

['2','7','9']

Use Cases of Node.js URLSearchParams.getAll():

  • Retrieving multiple values for the same query parameter.
