pdc

A pandoc wrapper for Node.js

Installation

npm install -s pdc
or
yarn add pdc

This package requires pandoc to be installed. By default, the wrapper assumes pandoc to be in PATH. You can set your own, customized path to the executable by assigning an absolute path to pdc.path.

Usage

Markdown to HTML

pandoc outputs all to stdout by default (except: docx, pdf, and some documented formats)

const promisify = require('util').promisify
const pdc = promisify(require('@rogov.tech/pdc'))

try {
  const result = await pdc('# Heading', 'markdown', 'html') //Buffer
  console.log(result.toString()) //String
} catch (error) {
  console.error(error)
}

This will print:

<h1 id="heading">Heading</h1>

HTML to DOCX

make pandoc write docx buffer to stdout use this flag --output=-

const promisify = require('util').promisify
const pdc = promisify(require('@rogov.tech/pdc'))

try {
  const result = await pdc('<p>Hello docx</p>', 'html', 'docx', '--output=-') //Buffer
  //..some operations with file buffer
} catch (error) {
  console.error(error)
}

API

pdc(src, from, to, [args,] [opts,] callback);

• src is a string containing the entire source text, that shall be converted.
• from is a string containing the type of the source text (e.g. 'markdown').
• to is a string containing the type of the destination text (e.g. 'html').
• args [optional] is an array with additional command line flags (e.g. [ '-v' ] for pandoc's version).
• opts [optional] is an object with additional options for the process. See the Node.js docs.
• callback is a function that is called after parsing. It takes two arguments (err, result), where err is an error or null and result is a string containing the converted text.

pdc.path = 'pandoc';

• pdc.path is a string containing the name or absolute path to the executable. Defaults to 'pandoc'.

pdc.stream(from, to, [args,] [opts])

This is an alternative way to run pandoc. If you need a way to manipulate the streams, that's the way to go.

• from is a string containing the type of the source text (e.g. 'markdown').
• to is a string containing the type of the destination text (e.g. 'html').
• args [optional] is an array with additional command line flags (e.g. [ '-v' ] for pandoc's version).
• opts [optional] is an object with additional options for the process. See the Node.js docs.
• Returns a ChildProcess, which allows you to use pandoc's stdin, stdout and stderr.

Credits

I’d like to thank John MacFarlane for creating such a great tool -- It adds so many possibilities to Markdown -- and of course John Gruber for creating Markdown itself.
