node-java-connector

This package helps with running JAR-Files from JavaScript. If no Java is installed on the system, a openJDK version will be installed temporarily.

An example can be found at https://github.com/NLueg/node-java-connector-example.

Getting Started

1. Install the package:

npm install node-java-connector

2. Define a file like install.js where you deal with installing the JRE with the following content:

const njb = require("node-java-connector");

njb
  .install()
  .then((dir) => {
    // do something with the directory
  })
  .catch((err) => {
    console.log(err);
  });

3. Add the script to your package.json that the JRE gets installed everytime when your package gets installed:

{
 ...
 "scripts": {
 "install": "node install.js",
 }
 ...
}

4. Use the executeJar method with the path to your JAR-file and optional arguments or executeClassWithCP for non-executable JARs.
