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
