/**
|
|
* Compiler frontend for node.js
|
|
*
|
|
* Uses the low-level API exported from src/index.ts so it works with the compiler compiled to
|
|
* JavaScript as well as the compiler compiled to WebAssembly (eventually). Runs the sources
|
|
* directly through ts-node if distribution files are not present (indicated by a `-dev` version).
|
|
*
|
|
* Can also be packaged as a bundle suitable for in-browser use with the standard library injected
|
|
* in the build step. See dist/asc.js for the bundle and webpack.config.js for building details.
|
|
*
|
|
* @module asc
