node-java-connector

!npm bundle size

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:

``sh
npm install node-java-connector
`

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

`js
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:

`json
{
...
"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.
