Make your own sayhello example

1. Write a file lib/sayhello.js

// lib/sayhello.js
function say() {
    console.log("hello");
}

exports.say = say;

exports.VERSIONINFO = "SayHello Library (sayhello.js) version 0.1";
exports.AUTHOR = "[email protected]";   // e.g. YOUR EMAIL ADDRESS
exports.global = global;
exports.require = global.require;

2. Write a file sayhello.js

// sayhello.js
var SayHello = require("lib/sayhello");

function main() {
    console.log("calling say()");
    SayHello.say();
    console.log("ended say()");
}

exports.main = main;

3. Execute file on the command prompt

C:\Users\knh94\Documents\GitHub\welsonjs> cscript app.js sayhello
calling say()
hello
ended say()

How to release my application?

The WelsonJS framework suggests the following application release methods:

  • Compress to Zip, and use the launcher: Compress the files and directories necessary for running the project into a Zip file, and distribute it along with the WelsonJS.Launcher.
  • Build a setup file: Use Inno Setup. Information needed to create the setup file (the setup.iss file) is already included.
  • Copy all directories and files: This is the simplest and most straightforward method.
