Lumo Unbundled

This is a proposal for creating a new package along with lumo-cljs containing all the un-bundled JavaScript files needed for the current lumo to work, like:

• target/bundle.min.js
• target/main.js
• target/main.js.map
• all the cljs deps files + source maps in target

The goal would be to obtain a TypeScript-like experience when developing ClojureScript projects, where lumo would JIT transpile and evaluate on the installed node runtime instead of using its own binary.

Advantages

• no compilation/bundle fiddling, meaning one can potentially use node bundle.js, basically getting lumo on Raspberry would be straightforward (see anmonteiro/lumo#374)

• we could embed lumo in existing node applications (see anmonteiro/lumo#306)

• existing tooling that allows transpilers to hook against them would work OOTB, one existing example is mocha - this could be achieved:

  mocha --compilers lumo-cljs/register --recursive ./test
  

• one could also use node --inspect against their (JS transpiled) app. I know this is uncommon for Clojure devs but very node-ish

• less friction when a JavaScript develop starts working in ClojureScript, basically what only lumo can do is to become JS-friendly "for real", this has already started with the deployment of packages on npm, but it can be further expanded.

Disadvantages

• a couple of weeks of work

• two modules to deploy

• ?

What are the two modules to deploy?
