Lodash _.fromQuery() Method

Lodash _.fromQuery() method is used to convert the given URL Query String into an equivalent JavaScript object.

Syntax:

_.fromQuery( URL_Query);

Parameters:

This method accepts a single parameter as mentioned above and described below:

• URL_Query: This method takes a URL Query String to convert into a JavaScript object.

Return Value:

This method returns the equivalent JavaScript Object.

Note: This will not work in normal JavaScript because it requires the lodash.js contrib library to be installed. Lodash.js contrib library can be installed using npm install lodash-contrib –save.

Example 1: In this example, the lodash-contrib library is used to convert a URL query string into a JavaScript object, extracting parameters like “name” with the value “ferret” and “color” with the value “purple” from the provided URL.

Javascript

// Defining lodash contrib variable
let _ = require('lodash-contrib');

let s  = _.fromQuery(
"https://geeksforgeeks.org/path/to/page?name=ferret&color=purple");

console.log("The generated JavaScript Object is : ", s);

Output:

The generated JavaScript Object is :
Object {
color: "purple" ,
https://geeksforgeeks.org/path/to/page?name: "ferret"
}

Example 2: In this example, the lodash-contrib library is employed to convert a URL query string into a JavaScript object, parsing parameters from the given URL, such as “ref” with the value “gfg_header.”

Javascript

// Defining lodash contrib variable
let _ = require('lodash-contrib');

let s  = _.fromQuery(
"https://practice.geeksforgeeks.org/courses/?ref=gfg_header");

console.log("The generated JavaScript Object is : ", s);

Output:

The generated JavaScript Object is :
Object {https://practice.geeksforgeeks.org/courses/?ref: "gfg_header"}
