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:

constnjb=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.
