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

$ npm install pdftk-simple

Usage

(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.
