What is this?

This package exposes an algorithm to make text safe for embedding in HTML.

When should I use this?

This package might be useful when you are making your own micromark extensions.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install micromark-util-encode

In Deno with esm.sh:

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

In browsers with esm.sh:

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

Use

import {encode} from 'micromark-util-encode'

encode('<3') // '&lt;3'

API

This module exports the identifier encode. There is no default export.

encode(value)

Encode only the dangerous HTML characters.

This ensures that certain characters which have special meaning in HTML are dealt with. Technically, we can skip > and " in many cases, but CM includes them.

Parameters

• value (string) — value to encode

Returns

Encoded value (string).

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, micromark-util-encode@2, compatible with Node.js 16. This package works with micromark@3.

Security

This package is safe. See security.md in micromark/.github for how to submit a security report.

he

The 'he' package is a robust HTML entity encoder/decoder written in JavaScript. It supports all named character references defined in HTML, handling encoding and decoding in a comprehensive manner. Compared to micromark-util-encode, 'he' offers a broader set of functionalities for dealing with HTML entities beyond just encoding, including decoding capabilities.

escape-html

The 'escape-html' package is a simple utility for escaping HTML entities in strings. It focuses solely on converting characters like '<', '>', '&', '"', and "'" into their corresponding HTML entities to prevent HTML injection. While it serves a similar purpose to micromark-util-encode in terms of preventing HTML injection, it does not belong to a larger markdown processing ecosystem and is more limited in scope.
