## What it is
URI.js is a JavaScript library for parsing, manipulating, and normalizing URLs with a fluent, jQuery-style chaining API. It supports query string handling, relative/absolute path conversion, URI normalization, and RFC 6570 URI Templates.

## Use cases
- parse and mutate URLs in JavaScript
- add or remove query string parameters from a URL
- convert relative paths to absolute URLs and vice versa
- expand URI templates with variables
- normalize messy URLs and query strings
- change hostname, TLD, directory, or file suffix of a URL

## When to choose
- you need rich URL mutation beyond what the native URL API offers
- you must support older browsers lacking URL/URLSearchParams
- you need RFC 6570 URI Template expansion
- you want second-level domain (TLD/S LD) aware URL handling

## When to avoid
- you only target modern browsers with native URL and URLSearchParams support
- you only need simple query string parsing
- you need an actively developed library with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, serialization, developer-tools
- domain: web-development, developer-tools, apis
- platform: browser, cross-platform
- tags: url-manipulation, uri-templates, query-strings, fluent-api, rfc-3986, rfc-6570, javascript, nodejs
