Easily wrap your WebApp into a frameless macOS Application.
To hide the app call "window.macOS.hide()" from JavaScript. For example:
<button onclick="window.macOS.hide()">CLOSE</button>
To move the window include the "macOS.moveWindow.js" file in the "web" directory. This small piece of JavaScript attaches an event handler to ".window-drag-handle" Elements and communicates its position to the Mac-Host-Window via "window.macOS.moveBy". You can also call this command directly if you so prefer:
window.macOS.moveBy(10,10);
