Last active December 14, 2015 01:58
Monkey patch express to support multiple view directories
View = require 'express/lib/view'
View::lookup = do ({ lookup } = View) -> (path) ->
return lookup.call this, path unless Array.isArray @root
return abs for root in @root when (abs = lookup.call { root }, path)?
###
Usage:
require 'express-multi-view-directories'
app.set 'views', ['...', '...', '...']

Require a file, and mock the modules returned to it from require()
Module = require 'module'
# native_module isn't public, mock the needed functionality
NativeModule = do (natives = Object.keys process.binding 'natives') ->
exists: (name) -> name in natives
require: require
mock = (request, parent, modules) ->
return modules[request] if request of modules
return NativeModule.require request if NativeModule.exists request

Decorate constructor functions, and have them return a callable object that delegates to a `callable()` method when invoked.

Inline client-side JavaScript with browserify and express
browserify = require 'browserify'
client = (mount, fn) -> (browserify { mount }).addEntry 'main.js', body: '(' + fn + ')()'
# Usage:
app = express()
app.use client '/client.js', ->
foo = require './foo'
bar = require 'bar'
foo 123, bar, 456

Last active December 10, 2015 23:30
possible implementations for partial application with pre-evaluated bound arguments and function target in CoffeeScript. See https://github.com/jashkenas/coffee-script/pull/2597
# With an helper function:
partial = (fn, a...) -> (b...) -> fn a..., b...
add_3 = partial add, 3
# With an IIFE:
add_3 = do (fn=add, a=3) -> (b...) -> fn a, b...
# note: because we know the number of bound arguments at compile-time, the do() IIFE could be
# compiled with the exact number of arguments, rather than with a splat.
# the do thingy is the same as `add_3 = ( (fn, a) -> (b...) -> fn a, b... ) add, 3`
