POC: ES2015 Modules Codegen (WIP)

[gasi]

Proof-of-concept for generating ES2015 modules for easier tree shaking / static analysis by external tools such as Webpack, Rollbar, etc.

Tasks

• Replace CommonJS module.exports with ES2015 export declarations in code-gen.
  • Handle invalid JavaScript identifiers such as fold', etc.
• Replace CommonJS require(…) with ES2015 import declarations for PureScript imports in code-gen.
• Allow FFI code with ES2015 modules by minimally supporting export (later import). For a smoother transition, we could require .mjs file extension for ES2015 modules, similar to how Node.js does it: https://medium.com/@giltayar/native-es-modules-in-nodejs-status-and-future-directions-part-i-ee5ea3001f71
  • export support in language-js: ES2015: Modules: export declarations (partial) erikd/language-javascript#80
