Simple test case:

1. In your jArchi script folder create a file test_module.ajs containing this:

const speaker = require("helloworld");
speaker.sayHelloWorld();

2. In your jArchi script folder create a sub-folder named node_modules
3. In the node_modules folder create a sub-folder named helloworld
4. In the helloworld folder create a file index.js containing this:

exports.sayHelloWorld = function() {
    window.alert("Hello World!");
}

5. Run the test_module.ajs script
