When you code, you do not create an application, you create in fact a system. System Runtime gives you the APIs to create the model, components and behaviors of your system.

A system:

• is defined by a model,
• is composed by components and
• reacts to events with actions that we call behaviors.

Use System Runtime APIs to create your system:

// create a system
const system = runtime.system('system');

// add some business logic in the start method
system.on('start', () => console.log('Hello world !'));

// run the system
system.start();

Now you can bundle your system into a JSON object:

// create a bundle
runtime.bundle();

It will return this JSON:

{
  "_id": "154cd18d0210516",
  "name": "system",
  "description": "",
  "version": "0.0.1",
  "schemas": {},
  "models": {},
  "types": {},
  "behaviors": {
    "1ea9c1d5f811ae1": {
      "_id": "1ea9c1d5f811ae1",
      "component": "154cd18d0210516",
      "state": "start",
      "action": "() => console.log('Hello world !')",
      "useCoreAPI": false,
      "core": false
    }
  },
  "components": {}
}

Just add a link tag in your HTML to install and start your bundle:

<!-- install your bundle -->
<link rel="system" type="application/json" href="system.json">

Just call install API to install and start your bundle:

// require System Runtime
const runtime = require('system-runtime');

// install your bundle 
runtime.install('system.json');

Creating a system in System Runtime is very simple, you do not have to code but just to define its model in a human readable format called MSON.

With MSON you can define types, classes, one to one / one to many relationships and multi inheritance between classes.

const metamodel = runtime.require('metamodel');

// create the Jedi schema
metamodel.schema('Jedi', {
  'firstName': 'property',
  'lastName': 'property',
  'nickname': 'property',
  'father': 'link',
  'shout': 'method'
});

metamodel.create();

Once your model is created, you will be able to get the classes of your model and create components based on your model.

Because you have defined a model for your system, a Dynamic Type Check is done on every action of your system.

// get your component class
const Jedi = runtime.require('Jedi');

// create components
const luke = new Jedi({
  'firstName': 'Luke',
  'lastName': 'Skywalker'
});

const anakin = new Jedi({
  'firstName': 'Anakin',
  'lastName': 'Skywalker'
});

// add a link
luke.father(anakin);

// get the first name of luke father
luke.father().firstName();

All your components are stored in System Runtime NoSQL Database. In fact, System Runtime acts as an ODM (Object-Document Mapper) to manage your components as NoSQL Documents.

You can find, create, update, delete components like you do in a NoSQL Database.

// get a collection
const Jedi = runtime.require('db').collections().Jedi;

// find components
Jedi.find({
  'firstName': 'Luke'
});

// update components
Jedi.update({
  'firstName': 'Anakin'
},{
  'nickname': 'Darth Vader'
});

// remove components
Jedi.remove({
  'firstName': 'Anakin'
});;

System Runtime contains a metamodel to help you to design your model. The definition of the model is made on a JSON format called MSON, no code is needed.

With MSON you can define types, classes, one to one / one to many relationships and multi inheritance between classes.

MSON is based on UML, so learning it is very easy.

System Runtime uses the Model-Driven Architecture approach to create classes based on your design. Use them to instantiate your components.

System Runtime acts as an ODM (Object-Document Mapper) to manage your components as NoSQL Documents.

System Runtime has a micro NoSQL Database that stores your components and you can export/import them into another System Runtime NoSQL Database.

Thanks to System Runtime NoSQL Database, you can compose your system with an another system.

System Runtime checks at runtime if the signatures of invoked methods are compliant with your model.

With System Runtime your components really behave the way you designed them.

Clone the repository:

git clone https://github.com/design-first/system-runtime.git

Once you have cloned the repository, install the dependencies:

npm i

Then build System Runtime:

npm run build

It will:

• build System Runtime core module for the server library and
• build System Runtime client library on /dist directory

To start System Runtime in development mode:

npm run dev

All the modifications to the source code of System Runtime will rebuild the project.
