make a module to require() in components

[forresto]

I want to make a constants.coffee module to require() in several components and tests. We need UI to do this, as well as the reworked build process to make it work in the browser.

Trying to work around it, made a fake Constants component, but it errors when I try to require('./Constants') it from another component:

Error: Failed to require "./Constants" from "noflo-noflo/src/lib/ComponentLoader.js"

because it is evaling the source from within ComponentLoader.

... I think we need a comprehensive solution to using CommonJS/Browserify/npm dependencies.

exports =
  Library:
    ROUTE: 'lib_actions'
    NEW_LIBRARY: 'new library'
    CHANGE_LIBRARY: 'change library'
  Graph:
    ROUTE: 'graph_actions'
    NEW_GRAPH: 'new graph'
    CHANGE_GRAPH: 'change graph'
    ADD_NODE: 'addNode'
  Error:
    NEED_NOFLO_GRAPH: 'IP should be a valid NoFlo Graph'

noflo = require 'noflo'
exports.getComponent = -> new noflo.Component

For current feature parity, we need to:

• compile coffeescript
• make modules so that they can be loaded by the ComponentLoader

We want to:

• require('cool-npm-module') see RequireBin and browserify-cdn
• require('./local-module-built-in-this-flowhub-project') browserify-browserify?
• compile so that Component.getSource can return original coffeescript (+ sourcemaps for errors)

Current workaround: Send an object with the constants as an IIP.
