Package Exports

node-java-connector
node-java-connector/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-java-connector) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

Install the package:

npm install node-java-connector

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);
  });

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

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

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