node-ark

A Node application creator about plugin architecture approach.

Quick Example

Create your module with npm

mkdir -p plugins/myMainPackager
cd plugins/myMainPackager
npm init
touch index.js

Create a plugin plugins/myMainPackager/index.js

module.exports = function setup(imports, done) {
    imports.myValueExported = 123;
 
    done(); // call done when finish it
}

Your main.js script:

var ark = require('node-ark');
 
ark.create(["plugins/myMainPackager"], function (imports) {
    console.log("My application is running! All plugins are loaded");
})

Here is your package.json:

{
  "name": "myMainPackager",
  "version": "0.0.1",
  "description": "My Demo Application",
  "main": "index.js",
}

Dependencies

Edit the package.json from plugin that require the dependency.

{
    "name": "myMainPackager",
    "version": "0.0.1",
    "description": "My Demo Application",
    "main": "index.js",
 
    "plugin": {
      "requires": [
          "plugins/myAnotherPlugin"
      ]
    }
}

Create a new plugin

Create a new package.json:

{
    "name": "myAnotherPlugin",
    "version": "0.0.1",
    "description": "My Plugin",
    "main": "myPluginSetup.js"
}

Create the target plugin plugins/myAnotherPlugin/myPluginSetup.js:

module.exports = function setup(imports, done) {
    imports.shareThisObject = {
        name: "Amazing plugin system",
        run: function () {
            return this.name + " is running"
        }
    };
 
    done(); // call done when finish it
}

Then, from myMainPackager.js plugin you can do access the shared object:

module.exports = function setup(imports, done) {
    var sharedObject = imports.shareThisObject;
 
    console.log("Who is?", sharedObject.name);
    console.log("Do what?", sharedObject.run());
 
    done(); // call done when finish it
}
