remark-stringify

Compiler for unified. Serializes mdast syntax trees to Markdown. Used in the remark processor but can be used on its own as well. Can be extended to change how Markdown is serialized.

Install

npm:

npm install remark-stringify

Use

var unified = require('unified')
var createStream = require('unified-stream')
var html = require('rehype-parse')
var rehype2remark = require('rehype-remark')
var stringify = require('remark-stringify')

var processor = unified().use(html).use(rehype2remark).use(stringify, {
  bullet: '*',
  fence: '~',
  fences: true,
  incrementListMarker: false
})

process.stdin.pipe(createStream(processor)).pipe(process.stdout)

See unified for more examples »

API

See unified for API docs »

`processor().use(stringify[, options])`

Configure the processor to serialize mdast syntax trees to Markdown.

`options`

Options can be passed directly, or passed later through processor.data().

All the formatting options of mdast-util-to-markdown are supported and will be passed through.

Extending the compiler

See mdast-util-to-markdown. Then create a wrapper plugin such as remark-gfm.

Security

remark-stringify will do its best to serialize markdown to match the syntax tree, but there are several cases where that is impossible. It’ll do its best, but complete roundtripping is impossible given that any value could be injected into the tree.

As Markdown is sometimes used for HTML, and improper use of HTML can open you up to a cross-site scripting (XSS) attack, use of remark-stringify and parsing it again later can potentially be unsafe. When parsing Markdown afterwards, use remark in combination with the rehype ecosystem, and use rehype-sanitize to make the tree safe.

Use of remark plugins could also open you up to other attacks. Carefully assess each plugin and the risks involved in using them.
