Local setup and development

You need to have TypeScript installed. In the project root, run tsc. This should run without errors and create the file app.js.

You need a webserver that locally serves the files from the project directory. If you have python installed, you can call python3 -m http.server. It will tell you the port, for example 8000, and you can visit http://localhost:8000 in your browser. Alternatively, you can install http-server, which will also create a server in port 8000.

If you work on the code, run tsc --watch, which will recompile everytime you change a source file.
