About this app

This small app was built as a learning exercise for a grandson who was studing CS at UGA. That's why all code in the /src/ folder is heavily commented!

No Jank!

The interesting bits of this exercise was the use of a resource-pool to improve performance and reduce V8-GC.

• See: /src/dotPool.ts

Unique partical effect

Below the clock are four slider controls. Try moving each slider to change the animation.
The partical-trails slider is most interesting. It controls the RGBA alpha channel to gradually fade out trails. The higher the slider value, the less trail fade.

HOT

This simple app demonstrates running my Hot-dev-server directly from JSR.
This app was built using my Hot dev server.
The contents in the /src/ folder have been bundled into the ./dist/bundle.js file.

Copy this Repo to use/learn about the Hot dev server

• Download and load a local copy in vsCode.
• To run Hot, press ctrl+shift+b (the vscode build shortcut)
• This will start the Hot-dev-server from JSR
• To see how this is configured, open the ./.vscode/tasks.json file and see HOT

This app is configured to code and build all front-end javascript from typescript files located in the /src/ folder.
These ts files are auto-transpiled and bundled on-change to a single ./dist/bundle.js file.
The index.html file in the root folder loads this javascript bundle.js and a css file from the /dist/ folder:

   <link rel="stylesheet" href="./dist/styles.css" />
   <script type="module" src="./dist/bundle.js"></script>

Note: keeping index.html in the root, allows us to run this from Github-Pages

Any changes to any ts file in the /src/ folder will cause a build/bundle/refresh of the browser.
Any changes to any css file in the /dist/ folder will cause a refresh of just the styles in the browser.

Unlike Vite or Deno serve, This simple dev-server requires:

• no deno.json
• no package.json
• no /node_modules/
• no frameworks

HOT is a tool to support the developement of pure HTML, CSS, vanilla javascript apps. It assumes no framework is required, while allowing client-side code to take enjoy the advantages of Typescript.

The unique thing about HOT is, like with Vite, you code directly in Typescript, but without all the node overhead of Vite.
