Asciidoctor.js: AsciiDoc in JavaScript powered by Asciidoctor

GitHub Actions Status npm version npm stats JSDoc project chat

Asciidoctor.js brings AsciiDoc to the JavaScript world!

This project uses Opal to transpile Asciidoctor, a modern implementation of AsciiDoc, from Ruby to JavaScript to produce asciidoctor.js. The asciidoctor.js script can be run on any JavaScript platform, including Node.js, GraalVM and, of course, a web browser.


$ npm i asciidoctor --save

Here is a simple example that converts AsciiDoc to HTML5:

const asciidoctor = require('asciidoctor')() // (1)
const content = '[*Asciidoctor*] ' +
  'running on[_Opal_] ' +
  'brings AsciiDoc to Node.js!'
const html = asciidoctor.convert(content) // (2)
console.log(html) // (3)
  1. Instantiate the Asciidoctor.js library

  2. Convert AsciiDoc content to HTML5 using Asciidoctor.js

  3. Print the HTML5 output to the console

Save the file as sample.js and run it using the node command:

$ node sample.js

You should see the following output in your terminal:

<div class="paragraph">
<p><a href=""><strong>Asciidoctor</strong></a> running on <a href=""><em>Opal</em></a> brings AsciiDoc to Node.js!</p>

It’s also possible to use the following script tag directly into your HTML page:

<script src="node_modules/@asciidoctor/core/dist/browser/asciidoctor.js"></script>
