A JavaScript library for parsing and stringifying URL query strings, with support for arrays, nested objects, and various encoding formats. It is a zero-dependency npm package by sindresorhus targeting modern browsers and Node.js.

Use cases

• parse url query strings into javascript objects
• stringify an object into a url query string
• parse arrays in query parameters with bracket or comma format
• extract query parameters from location.search or location.hash
• encode and decode url parameters safely
• build query strings for api requests

When to choose

• you need robust query string parsing with array and object support beyond native URLSearchParams
• you want a small, zero-dependency, well-tested utility
• you need consistent handling of encoding, decoding, and custom array formats

When to avoid

• you only need basic query string operations - the native URLSearchParams API may suffice
• you need legacy browser support, as it targets only modern Chrome, Firefox, and Safari
