System Designer uses UML, a standard, to define your model. So you probably already know how to design in System Designer even if you have never run it.
The definition of the model is stored 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.
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 through components to create your system.
function fullName() {
let result = '';
// for each property a method
// is created to set / get its value
result = this.firstName() + ' ' +
this.lastName();
// a dynamic type check is done
// to validate that inputs and ouput
// are compliant with the model
return result;
}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 system directly from System Designer and then export it to JavaScript, HTML, JSON, a Node.js module or a Graphviz file (* Windows, macOS, Linux and PWA versions only).
Because you have defined a model for your system, a Dynamic Type Check is done on every action of your system. All warnings are send and shown in System Designer.
System Designer can load the model of any system that runs on the browser or on Node.js (* Windows, macOS, Linux and PWA versions only). You can see the schemas, models, components and methods of the running system and you can edit them.
All modifications to the model done inside System Designer will be send to the running system. There is no need to reload to see your modifications.
System Designer can be used on Windows, macOS, Linux, iPad, iPhone, Android or any browsers. You can also install it in your project: System Designer requires no backend to work, it is a full web application.
System Designer has a GitHub module to synchronize your work between all these apps. You can begin your design on your Mac and then continue it on your iPad.
