form-urlencoded

What is form-urlencoded?

The form-urlencoded npm package is used to encode and decode URL-encoded form data. It is particularly useful for working with HTTP requests and responses where data needs to be sent or received in the application/x-www-form-urlencoded format.

What are form-urlencoded's main functionalities?

Encoding an Object to URL-encoded String

This feature allows you to convert a JavaScript object into a URL-encoded string, which is useful for sending data in HTTP POST requests.

const formurlencoded = require('form-urlencoded');
const data = { name: 'John Doe', age: 30, city: 'New York' };
const encoded = formurlencoded(data);
console.log(encoded); // Output: 'name=John%20Doe&age=30&city=New%20York'

Decoding a URL-encoded String to an Object

This feature allows you to convert a URL-encoded string back into a JavaScript object, which is useful for processing data received in HTTP POST requests.

const formurlencoded = require('form-urlencoded');
const encoded = 'name=John%20Doe&age=30&city=New%20York';
const decoded = formurlencoded.parse(encoded);
console.log(decoded); // Output: { name: 'John Doe', age: '30', city: 'New York' }

Returns 'x-www-form-urlencoded' string data, an encoding often used when an HTML form is submitted. Form data is serialised in this format and sent to a server.

var formurlencoded = require('form-urlencoded');
var obj = {
  str : 'val',
  num : 0,
  arr : [3, {prop : false}, 1, null, 6],
  obj : {prop1 : null, prop2 : ['elem']}
};

console.log(formurlencoded(obj));
// str=val&num=0&arr%5B0%5D=3&arr%5B1%5D%5Bprop%5D=false
// &arr%5B2%5D=1&arr%5B3%5D=null&arr%5B4%5D=6&obj%5Bprop
// 1%5D=null&obj%5Bprop2%5D%5B0%5D=elem

console.log(formurlencoded(obj, {
  ignorenull : true,
  skipIndex : true,
  sorted : true
}));
// arr%5B%5D=3&arr%5B%5D%5Bprop%5D=false&arr%5B%5D=1&arr
// %5B%5D=6&num=0&obj%5Bprop2%5D%5B%5D=elem&str=val
