Subject Re: Node.js support

Oh, I see! I was confused. I now recall seeing that you were working on
getting FlexJS into NPM.

I thought you meant that you were working on the compiler to add support
for Node.js modules. Getting the compiler to output good code for running
on Node.js is something that I hope to work on soon.

For those not familiar, Node.js modules are referenced with calls to
require(), like this:

var fs = require("fs");

It's almost like an import in ActionScript. I'm hoping to get the emitter
to output the right require() calls for any classes that are from CommonJS
modules used by Node.js. That's why I mentioned metadata.

As far as NPM goes, let me share something that I learned while working on
my dts2as utility. If you want someone to be able to use commands like
asjsc directly from the command line, they need to install the package
globally. It won't work for packages installed locally.

npm install -g flexjs
asjsc src/HelloWorld.as

Okay, technically, you can run commands from local packages. It's just a
little messy, so I think people avoid it:

npm install -g flexjs
./node_modules/.bin/asjsc src/HelloWorld.as

To get asjsc and other commands to work, you should be able to add them to
package.json. Here's how I did it in dts2as:

"bin": {
  "dts2as": "./bin/dts2as"
}

For FlexJS, I think something like this should work:

"bin": {
  "asjsc": "./js/bin/asjsc",
  "asjscompc": "./js/bin/asjscompc"
}
