Currently bundling is being done with help of the builtin Deno bundling, so this is not a perfect solution or one that is meant to work on every browser out there

To start the server with all the correct permissions you need to run

deno run --allow-read=public --allow-net=0.0.0.0:3000 mod.ts

To bundle your project (the webserver expects an app.js file to exist at all times in the public folder) you need to run the following command

deno bundle client/App.tsx public/app.js
