What are @smithy/querystring-parser's main functionalities?
Parse Query String
This feature allows you to parse a query string into a JavaScript object. The `parse` function takes a query string as input and returns an object with key-value pairs.
const { parse } = require('@smithy/querystring-parser');
const queryString = 'name=John&age=30&city=New%20York';
const parsed = parse(queryString);
console.log(parsed); // { name: 'John', age: '30', city: 'New York' }
Stringify Object to Query String
This feature allows you to convert a JavaScript object into a query string. The `stringify` function takes an object as input and returns a URL-encoded query string.
const { stringify } = require('@smithy/querystring-parser');
const obj = { name: 'John', age: '30', city: 'New York' };
const queryString = stringify(obj);
console.log(queryString); // 'name=John&age=30&city=New%20York'
