Asciidoctor.js: AsciiDoc in JavaScript powered by Asciidoctor

This package is a convenience wrapper that bundles @asciidoctor/core and the Asciidoctor CLI. It provides a native JavaScript implementation of Asciidoctor with no compilation step.

The API is asynchronous: all parsing and conversion operations return a Promise.

Requirements

Node.js >= 24

Install

$ npm i asciidoctor --save

Usage

Convert a string

sample.js

import asciidoctor from 'asciidoctor'

const content = 'https://asciidoctor.org[*Asciidoctor*] running on Node.js!'
const html = await asciidoctor.convert(content) // ①
console.log(html) // ②

1. Convert AsciiDoc content to HTML5 — the call returns a Promise and must be awaited
2. 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="https://asciidoctor.org"><strong>Asciidoctor</strong></a> running on Node.js!</p>
</div>

Convert a file

convert-file.js

import { convertFile } from 'asciidoctor'

await convertFile('document.adoc', { safe: 'safe' })

Load without converting

Use load when you need to inspect the parsed document model before (or instead of) converting:

load.js

import { load } from 'asciidoctor'

const doc = await load('== Hello, World!\n\nThis is Asciidoctor.')
console.log(doc.getTitle())    // Hello, World!
console.log(doc.getBlocks())   // array of top-level blocks
const html = await doc.convert()
console.log(html)

CLI

The asciidoctor command is available after installation:

$ asciidoctor document.adoc

Common options:

$ asciidoctor -b html5 -a toc document.adoc
$ asciidoctor -o - document.adoc          # output to stdout
$ asciidoctor --help                       # show all options
$ asciidoctor --help syntax                # show AsciiDoc syntax reference
