API

See unified for API docs Β»

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

Configure the processor to stringify mdast syntax trees to Markdown.

options

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

options.gfm

Stringify with the required escapes for GFM compatible Markdown (boolean, default: true).

options.commonmark

Stringify for CommonMark compatible Markdown (boolean, default: false).

options.pedantic

Stringify for pedantic compatible markdown (boolean, default: false).

options.entities

How to stringify entities (string or boolean, default: false):

options.setext

Compile headings, when possible, in Setext-style (boolean, default: false). Uses = for level one headings and - for level two headings. Other heading levels are compiled as ATX (respecting closeAtx).

options.closeAtx

Compile ATX headings with the same amount of closing hashes as opening hashes (boolean, default: false).

options.looseTable

Create tables without fences: initial and final pipes (boolean, default: false).

options.spacedTable

Create tables with a space between a pipe and content (boolean, default: true).

options.paddedTable

Create tables with more spaces so that all cells in a column align (boolean, default: true).

options.stringLength

Function passed to markdown-table to detect the length of a table cell (Function, default: s => s.length). Used to pad tables.

options.fence

Marker to use for fenced code blocks ('~' or '`', default: '`').

options.fences

Create code blocks with a fence instead of indentation if they have no info string (boolean, default: false).

When false, code blocks are indented. Code blocks with an info string are always fenced.

options.bullet

Marker to use for the bullet of unordered list items ('-', '*', or '+', default: '-').

options.listItemIndent

Style of indentation for list items ('tab', 'mixed' or '1', default: 'tab').

options.incrementListMarker

Increment ordered list item numbers (boolean, default: true).

When false, all list item numbers will be the same.

options.rule

Marker to use for thematic breaks / horizontal rules ('-', '*', or '_', default: '*').

options.ruleRepetition

Number of markers to use for thematic breaks / horizontal rules (number, default: 3). Musts be 3 or more.

options.ruleSpaces

Place a space between thematic break (horizontal rule) markers (boolean, default true).

options.strong

Marker to use for importance ('_' or '*', default '*').

options.emphasis

Marker to use for emphasis ('_' or '*', default '_').

stringify.Compiler

Access to the compiler, if you need it.

Extending the Compiler

If the remark-stringify plugin is used, it adds a Compiler constructor function to the processor. Other plugins can add visitors to its prototype to change how Markdown is compiled.

The below plugin modifies a visitor to add an extra blank line before headings with a rank of 2.

module.exports = gap

function gap() {
  var Compiler = this.Compiler
  var visitors = Compiler.prototype.visitors
  var original = visitors.heading

  visitors.heading = heading

  function heading(node) {
    return (node.depth === 2 ? '\n' : '') + original.apply(this, arguments)
  }
}

Compiler#visitors

Map of types to visitors (Object.<Function>).

function visitor(node[, parent])

Stringify node.

Parameters
Returns

string β€” Compiled given node.

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.
