Install

Install using npm or yarn:

npm i ufo
# or
yarn add ufo

Import:

// CommonJS
const { normalizeURL, joinURL } = require('ufo')

// ESM
import { normalizeURL, joinURL } from 'ufo'

Notice: You may need to transpile package and add URL polyfill for legacy environments

Usage

normalizeURL

• Ensures URL is properly encoded
• Ensures pathname starts with slash
• Preserves protocol/host if provided

// Result: test?query=123%20123#hash,%20test
normalizeURL('test?query=123 123#hash, test')

// Result: http://localhost:3000/
normalizeURL('http://localhost:3000')

joinURL

// Result: a/b/c
joinURL('a', '/b', '/c')

resolveURL

// Result: http://foo.com/foo/bar/baz?test=123#token
joinURL('http://foo.com/foo?test=123#token', 'bar', 'baz')

withQuery

// Result: /foo?page=a&token=secret
withQuery('/foo?page=a', { token: 'secret' })

getQuery

// Result: { test: '123', unicode: '好' }
getQuery('http://foo.com/foo?test=123&unicode=%E5%A5%BD')

$URL

Implementing URL interface with some improvements:

• Supporting schemeless and hostless URLs
• Supporting relative URLs
• Preserving trailing-slash status
• Decoded and mutable classs properties (protocol, host, auth, pathname, query, hash)
• Consistent URL parser independent of environment
• Consistent encoding independent of environment
• Punycode support for host encoding

withTrailingSlash

Ensures url ends with a trailing slash

// Result: /foo/
withTrailingSlash('/foo')

withoutTrailingSlash

Ensures url does not ends with a trailing slash

// Result: /foo
withoutTrailingSlash('/foo/')

cleanDoubleSlashes

Ensures url does not have double slash (except for protocol)

// Result: /foo/bar/
cleanDoubleSlashes('//foo//bar//')
// Result: http://example.com/analyze/http://localhost:3000/
cleanDoubleSlashes('http://example.com/analyze//http://localhost:3000//')
