Common example

This example lints Markdown and turns it into HTML.

var remark = require('remark')
var recommended = require('remark-preset-lint-recommended')
var html = require('remark-html')
var report = require('vfile-reporter')

remark()
  .use(recommended)
  .use(html)
  .process('## Hello world!', function(err, file) {
    console.error(report(err || file))
    console.log(String(file))
  })

Yields:

1:1  warning  Missing newline character at end of file  final-newline  remark-lint

⚠ 1 warning
<h2>Hello world!</h2>
Settings through data

This example prettifies Markdown and configures remark-parse and remark-stringify through data.

var remark = require('remark')

remark()
  .data('settings', {commonmark: true, emphasis: '*', strong: '*'})
  .process('_Emphasis_ and __importance__', function(err, file) {
    if (err) throw err
    console.log(String(file))
  })

Yields:

*Emphasis* and **importance**
Settings through a preset

This example prettifies Markdown and configures remark-parse and remark-stringify through a preset.

var remark = require('remark')

remark()
  .use({
    settings: {commonmark: true, emphasis: '*', strong: '*'}
  })
  .process('_Emphasis_ and __importance__', function(err, file) {
    if (err) throw err
    console.log(String(file))
  })

Yields:

*Emphasis* and **importance**

API

Security

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 can also be unsafe. When going to HTML, 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.
