What is this?

This package is a unified (remark) plugin to configure remark (specifically, how remark-stringify formats markdown) from YAML frontmatter.

When should I use this?

This project is useful when you want to change how markdown is formatted from within a file. You can use this when you trust authors and want to give them control.
This plugin is very similar to the alternative remark-comment-configremark-comment-config. The difference is that that plugin uses comments, which can come anywhere in the document, whereas this plugin uses YAML frontmatter, which comes at the start of documents.

Install

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

npm install remark-yaml-config

In Deno with esm.shesmsh:

import remarkYamlConfig from 'https://esm.sh/remark-yaml-config@7'

In browsers with esm.shesmsh:

<script type="module">
  import remarkYamlConfig from 'https://esm.sh/remark-yaml-config@7?bundle'
</script>

Use

Say we have the following file example.md:

```markdown

remark: bullet: "+" ---

• Triton

…and a module `example.js`:

```js
import {remark} from 'remark'
import remarkFrontmatter from 'remark-frontmatter'
import remarkYamlConfig from 'remark-yaml-config'
import {read} from 'to-vfile'

const file = await remark()
  .use(remarkFrontmatter)
  .use(remarkYamlConfig)
  .process(await read('example.md'))

console.log(String(file))

⚠️ Important: remark-frontmatterremark-frontmatter is needed to support YAML frontmatter in markdown.

…then running node example.js yields:

```markdown

remark: bullet: "+" ---

• Triton

```

API

This package exports no identifiers. The default export is remarkYamlConfigapi-remark-yaml-config.

unified().use(remarkYamlConfig)

Configure remark with YAML frontmatter.
Parses YAML frontmatter and takes the value of the remark field as settings. The settings are passed to remark-stringifyremark-stringify-options.

Parameters

There are no parameters.

Returns

Nothing (undefined).

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-yaml-config@^7, compatible with Node.js 16.
This plugin works with remark version 13+. Version 5 (and lower) worked with older versions of remark.

Security

Use of remark-yaml-config can change how markdown is parsed or compiled. If the markdown is user provided, this may open you up to a cross-site scripting (XSS)wiki-xss attack.
