What is this?

This package exposes an algorithm to decode numeric character references.

When should I use this?

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

Install

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

``sh
npm install micromark-util-decode-numeric-character-reference
`

In Deno with [esm.sh][esmsh]:

`js
import {decodeNumericCharacterReference} from 'https://esm.sh/micromark-util-decode-numeric-character-reference@1'
`

In browsers with [esm.sh][esmsh]:

`html

`

Use

`js
import {decodeNumericCharacterReference} from 'micromark-util-decode-numeric-character-reference'

decodeNumericCharacterReference('41', 16) // 'A'
decodeNumericCharacterReference('65', 10) // 'A'
decodeNumericCharacterReference('A', 16) // '\n'
decodeNumericCharacterReference('7F', 16) // '�' - Control
decodeNumericCharacterReference('110000', 16) // '�' - Out of range
`

API

This module exports the identifier:
[decodeNumericCharacterReference][api-decode-numeric-character-reference].
There is no default export.

$3

Turn the number (in string form as either hexa- or plain decimal) coming from
a numeric character reference into a character.

Sort of like String.fromCodePoint(Number.parseInt(value, base)), but makes
non-characters and control characters safe.

###### Parameters

* value (string)
— value to decode
* base (number, probably 10 or 16)
— numeric base

###### Returns

Character (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-decode-numeric-character-reference@2, compatible with
Node.js 16.
This package works with micromark@3.

Security

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