What is this?

This package is a unified (remark) plugin to turn gemoji shortcodes into emoji.

When should I use this?

You can use this plugin to match how GitHub turns gemoji (GitHub Emoji) shortcodes into emoji. This plugin does not support other platforms such as Slack and what labels they support.

A different plugin, remark-gfm, adds support for GFM (GitHub Flavored Markdown). GFM is a set of extensions (autolink literals, footnotes, strikethrough, tables, and tasklists) to markdown that are supported everywhere on GitHub.

Another plugin, remark-frontmatter, adds support for YAML frontmatter. GitHub supports frontmatter for files in Gists and repos.

Install

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

npm install remark-gemoji

In Deno with esm.sh:

import remarkGemoji from 'https://esm.sh/remark-gemoji@8'

In browsers with esm.sh:

<script type="module">
  import remarkGemoji from 'https://esm.sh/remark-gemoji@8?bundle'
</script>

Use

Say we have the following file example.md:

Look, the moon :new_moon_with_face:

Here’s a family :family_man_man_boy_boy:

Слава Україні!  :ukraine:

…and a module example.js:

import remarkGemoji from 'remark-gemoji'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'

const file = await unified()
  .use(remarkParse)
  .use(remarkGemoji)
  .use(remarkStringify)
  .process(await read('example.md'))

console.log(String(file))

…then running node example.js yields:

Look, the moon 🌚

Here’s a family 👨‍👨‍👦‍👦

Слава Україні!  🇺🇦

API

This package exports no identifiers. The default export is remarkGemoji.

unified().use(remarkGemoji)

Turn gemoji shortcodes (:+1:) into emoji (👍).

Parameters

There are no parameters.

Returns

Transform (Transformer).

Syntax

This plugin looks for the regular expression /:(\+1|[-\w]+):/g in text in markdown (excluding code and such). If the value between the two colons matches a know gemoji shortcode, then its replaced by the corresponding emoji.

In EBNF, the grammar looks as follows:

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, remark-gemoji@^8, compatible with Node.js 16.

This plugin works with unified version 3+ and remark version 4+.

Security

Use of remark-gemoji does not involve rehype (hast) or user content so there are no openings for cross-site scripting (XSS) attacks.
