PDFTk-Simple
============

PDFTk for Node.js

About
-----

This is a small JavaScript library for use in Node.js
environments, providing the possibility to run the Java-based
PDFTk tool from within a
JavaScript API.

NOTICE
------

The PDFTk is written in Java
and hence this Node.js modules requires an installed java
executable in the environment.

Installation
------------

``shell
$ npm install pdftk-simple
`

Usage
-----

`js
(async () => {
const PDFTk = require("pdftk")
const pdftk = new PDFTk()
await pdftk.exec("multibackground", "foo.pdf", "bar.pdf")
})().catch((err) => {
console.log(ERROR: ${err})
})
`

Motivation
----------

The major differences of pdftk-simple
to similar NPM modules and the motivation for the existence of
pdftk-simple is that, in contrast to
other approaches, it does not need a pre-installed PDFTk. Instead, it
automatically downloads and locally installs the PDFTk distribution on
npm install and uses the plain java(1) command to execute it.

Latest pre-build PDFTk distributions can always be found under the
PDFTk CI/CD Jobs. You can
download a newer pdftk-all.jar manually and use the pdftk-simpe API
option pdftk` to specify the path to your particular JAR file.
