Run your own code on the server. Here we create a file at a position that will be displayed on the page, set its type to [app-1], create a file named [.Inline] inside it, set its type to [sjs-4] and make it print hello world.
In Object Oriented Programming (OOP), there are some kind of types and instances. In Boomla, there are apps and instances. A file's type can be a path.
Set it to an app's path and it becomes an instance of that app.
To directly serve a request, implement the [.Request] method.
Make content areas on a page editable by simply adding HTML markup.
Modularize your code with CommonJS style modules.
Create the file [APP/.Contextmenu/ENTRY] to add an ENTRY to the contextmenu of an APP and all its instances.
