Nodetuts in CoffeeScript (jaigouk.com)

For those who wondered what nodetuts is: http://nodetuts.com/

It is a Node.js Free screencast tutorials tool

in 1:

  'Content-Type': 'text/pain'

Should read 'text/plain'

in 2:

  spawn('tail' , ['-f', '/var/log/system.log']) 

I prefer to write

  spawn 'tail', ['-f', '/var/log/system.log']

---

  res.write(data)

Why not:

  res.write data

Applies to all calls.

---

  spawn= require('child_process').spawn

This is better written as:

  {spawn} = require 'child_process'

In 5:

  conn.end() if line == 'quit' 

Better (or more idiomatic):

  conn.end() if line is 'quit'

In 7:

  if !username

Perhaps more idiomatic:

  if not username

In 9:

  app.set 'view options', {layout: true}

I think this is cleaner, but it is mostly a preference:

  app.set 'view options', layout: true

Especially because in 10 you do:

  res.render 'products/show', locals: product: product

Where it WOULD make sense to use curly braces, for the sake of clarity:

  res.render 'products/show', locals: { product : product }

In 13:

  photos.list (err, photo_list) -> 

Just to be consistent I would use CamelCase for arguments as well.

In 14:

  console.log('%s %s', req.method, req.url)

What's up with this? Why not:

  console.log "#{req.method} #{req.url}"

In 15:

  module.exports.generate

You're fine using here:

  exports.generate

---------------------------------

Normally I consider it a dickmove to correct people in public, but in this case it's the right thing to do because a lot of folks inexperienced with CoffeeScript will read your examples.

lovely work!
