Coffee-Streamline

Helper for efficiently require()'ing CoffeeScript and/or Streamline files. The key word is "efficiently": compiled code is cached to prevent recompilation on subsequent runs.

Note that Streamline does natively support caching compiled code, but it only caches the Streamline compilation; CoffeeScript is compiled every time there. This module caches both types of compilation.

This module is also robust to version changes (upgrades) to both CoffeeScript and Streamline; files will be properly recompiled in those cases.

Installation

npm install coffee-streamline

Note that CoffeeScript and Streamline should also be installed like normal, e.g. your package.json should specify the desired versions of those.

Usage

You can simply require() this module in place of both CoffeeScript and Streamline; all proper require() handlers will be registered:

require('coffee-streamline');

You can then require() CoffeeScript and/or Streamline files like normal, and they'll be compiled and cached automatically:

require('./foo');   // e.g. foo.coffee
require('./bar');   // e.g. bar._js
require('./baz');   // e.g. baz._coffee

Details

Cached files are stored in a .cache directory under the current working directory at runtime (process.cwd()). This is to support deploying the compiled files alongside the source ones, e.g. via rsync.

Currently, Streamline compilation happens under "callback" mode.

TODO

Support configuration/options, e.g. cache directory location and Streamline compilation mode (callbacks or fibers).

Can/should some of this be integrated into Streamline directly?
