If you ever need to put HTML/CSS/JS or Web server inside native window

That is, webview; but the performance varies. Also, executable sizes.

Performant WebView alternatives to Electron

I know there is Neutralino.js, but some options are not customizable to my liking. Also, I need a complex backend solution anyway, so I created k-neu.

patarapolw / k-neu

Kotlin version of Neutralino.js

Now, putting in a native window is very simple,

Get JAR files here, https://github.com/patarapolw/k-neu/releases

Create config.json and put in alongside the JAR file of your OS.

{
  "title": "app1",
  "url": "index.html",
  "maximized": true
}

Or,

{
  "title": "app2",
  "server": ["java", "-jar", "server.jar"],
  "url": "http://localhost:${PORT}",
  "maximized": true
}

Of course, you can just edit App.kt directly. So that you can run server without multiple JAR files.

Now, you still have to ask the client to install Java Runtime Environment (JRE).
