## What it is
ufo is a lightweight TypeScript library providing human-friendly URL utilities for parsing, joining, normalizing, and encoding URLs. It is part of the UnJS ecosystem and works in Node.js, Deno, Bun, and browsers.

## Use cases
- parse urls into path, query, and hash parts
- join and normalize url paths safely
- encode and decode url path and query components
- extract hostname and port from a url string
- get the filename from a url path
- handle punycode encoding for hostnames

## When to choose
- you need reliable URL manipulation in JavaScript or TypeScript across runtimes
- you want a tiny dependency-free utility instead of the full WHATWG URL API
- you are building frameworks or tools that need consistent URL normalization and joining

## When to avoid
- you only need the native URL and URLSearchParams APIs available in your runtime
- you need full RFC-compliant URL validation or IDNA processing beyond basic punycode

## Facets
- artifact type: library
- maturity: active
- function: parser, serialization, developer-tools
- domain: web-development, developer-tools, apis
- platform: bun, cross-platform
- tags: url-parsing, url-manipulation, typescript, esm, unjs, nodejs, deno
