System Designer

System Designer uses UML, a standard, to define your model. So you probably already know how to create a model in System Designer even if you have never run it.

The definition of the model is stored on a JSON format called MSON. With MSON you can define types, classes, one to one / one to many relationships and multi inheritance between classes.

Once you have created your model, System Designer generates the skeletons of all your methods. You only have then to add your code to implement them.

System Designer provides you helpers to manage your components. You can easily navigate threw components to create your application.

There is no need to code to instantiate a component. Create a component in System Designer is like creating a document in a NoSQL Database.

In fact, System Designer acts as an ODM (Object-Document Mapper) to manage your components as NoSQL Documents.

You can run your application directly from System Designer and then export it to HTML, JSON or a Node.js module (* macOS and Chrome Web App version only).

Because you have defined a model for your application, a Dynamic Type Check is done on every action of your application. All warnings are send and shown in System Designer.
