Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, 16.0+, 18.0+), install with npm:

npm install micromark-util-sanitize-uri

In Deno with esm.sh:

import {sanitizeUri} from 'https://esm.sh/micromark-util-sanitize-uri@1'

In browsers with esm.sh:

<script type="module">
  import {sanitizeUri} from 'https://esm.sh/micromark-util-sanitize-uri@1?bundle'
</script>

Use

import {sanitizeUri} from 'micromark-util-sanitize-uri'

sanitizeUri('https://example.com/a&b') // 'https://example.com/a&b'
sanitizeUri('https://example.com/a%b') // 'https://example.com/a%25b'
sanitizeUri('https://example.com/a%20b') // 'https://example.com/a%20b'
sanitizeUri('https://example.com/👍') // 'https://example.com/%F0%9F%91%8D'
sanitizeUri('https://example.com/', /^https?$/i) // 'https://example.com/'
sanitizeUri('javascript:alert(1)', /^https?$/i) // ''
sanitizeUri('./example.jpg', /^https?$/i) // './example.jpg'
sanitizeUri('#a', /^https?$/i) // '#a'

API

This module exports the following identifiers: sanitizeUri. There is no default export.

sanitizeUri(url[, pattern])

Make a value safe for injection as a URL.

This encodes unsafe characters with percent-encoding and skips already encoded sequences (see normalizeUri internally). Further unsafe characters are encoded as character references (see micromark-util-encode).

A regex of allowed protocols can be given, in which case the URL is sanitized. For example, /^(https?|ircs?|mailto|xmpp)$/i can be used for a[href], or /^https?$/i for img[src] (this is what github.com allows). If the URL includes an unknown protocol (one not matched by protocol, such as a dangerous example, javascript:), the value is ignored.

Parameters

• url (string) — URI to sanitize.
• pattern (RegExp, optional) — Allowed protocols.

Returns

string — Sanitized URI.

normalizeUri(url[, pattern])

Normalize a URL (such as used in definitions).

Encode unsafe characters with percent-encoding, skipping already encoded sequences.

Parameters

• url (string) — URI to normalize.

Returns

string — Normalized URI.
