This package is a unified (remark) plugin to link references to commits,
issues, and users: @wooorm
-> [**@wooorm**](https://github.com/wooorm)
.
This project is useful if you want to emulate how markdown would work in GitHub comments, issues, PRs, or releases, but it’s actually displayed somewhere else (on a website, or in other places on GitHub which don’t link references, such as markdown in a repo or Gist). This plugin does not support other platforms such as GitLab or Bitbucket and their custom features.
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-breaks
, turns soft line endings
(enters) into hard breaks (<br>
s).
GitHub does this in a few places (comments, issues, PRs, and releases), but it’s
not semantic according to HTML and not compliant to markdown.
Yet another plugin, remark-frontmatter
, adds support
for YAML frontmatter.
GitHub supports frontmatter for files in Gists and repos.
This package is ESM only. In Node.js (version 16+), install with npm:
npm install remark-github
In Deno with esm.sh
:
import remarkGithub, {defaultBuildUrl} from 'https://esm.sh/remark-github@12'
In browsers with esm.sh
:
<script type="module">
import remarkGithub, {defaultBuildUrl} from 'https://esm.sh/remark-github@12?bundle'
</script>
Say we have the following file example.md
:

…and a module example.js
:
import {remark} from 'remark'
import remarkGfm from 'remark-gfm'
import remarkGithub from 'remark-github'
import {read} from 'to-vfile'
const file = await remark()
.use(remarkGfm)
.use(remarkGithub)
.process(await read('example.md'))
console.log(String(file))
…then running node example.js
yields:

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-github@^12
,
compatible with Node.js 16.
This plugin works with unified
version 6+ and remark
version 7+.
Use of remark-github
does not involve rehype (hast).
It does inject links based on user content, but those links only go to GitHub.
There are no openings for cross-site scripting (XSS) attacks.
remark-gfm
— support GFM (autolink literals, footnotes, strikethrough, tables, tasklists)remark-breaks
— support breaks without needing spaces or escapes (enters to<br>
)remark-frontmatter
— support frontmatter (YAML, TOML, and more)
