Support boilerplate for TypeScript projects

I would like to support boilerplate code for ReasonML, TypeScript,
ClojureScript, and Elm projects before I specialize in any of these
frameworks. All of my projects should use TailwindCSS.

All of this boilerplate should offer:
- Same command to start developing
- Same API to build and deploy
- TailwindCSS support
- Basic boilerplate for components, state, and routes

This TypeScript boilerplate is not complete, but I would like to commit the
progress in case I do not return to this for awhile.
