Application
< / h1 >
< p >
IWM Browser Applications follow a common three phase pattern, shared by many programming environments as diverse as Processing, Arduino, Intern, etc.
< ul >
< li > Instantiate: Initialize the application, in this case a singleton and it's instance variables< / li >
< li > Setup: Build more complex parts of the application, by loading data, creating the UI...< / li >
< li > Run: Enter and run the main loop of the application.< / li >
< / ul >
This pattern is reflected by the IApp Interface:
< / p >

< pre > < code class = "js" >
class IApp extends Interface {
setup() { return this }
run() { return this }
}
< / code > < / pre >

< p > In practice the pattern may be more complex, because the setup phase can only be entered after loading things, a main loop cannot be entered because requirements are not met, etc. But the basic structure is always the same:
< / p >
< script type = "module" class = "doctest" >
console.log("Innerhalb script type=module")
import App from "./app.js"
const app = new App()
app.setup()
app.run()
window.app = app
< / script >
< p > The setup and run methods can also be chained:
< / p >
< script type = "module" class = "doctest" >
app.setup().run()
< / script >
