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>
|
||
