poc: custom slint ts/js runtime

[FloVanGH]

Idea is to check if it is possible and is it worth to create a custom runtime tool for Slint apps build with TypeScript and JavaScript. Plan is to use the deno runtime as base for this concept evaluation.

To make it easier to work on this and to check if the proof of concept is a success it's need to define a goal, a story that is split in a list of todo items.

Story / Goal

The goal is to develop an example Slint app with JavaScript that fulfill the following requirements:

• Create and show a Slint component (e.g. export component MyWindow form Window {}) from JavaScript code
• Execute an async function that is defined in JavaScript from the Slint component
• Display the result of the function in the Slint component
• Embedded resource in the Slint component like an image
• Deploy a standalone executable on Linux (format: AppImage)
