Building a web-application involves multiple components.

The basic directory layout follows the MVC pattern

  • controllers
  • models
  • views

Static resources are served from the public directory.

  • express as a web development framework
  • mongoDB, a document-oriented database, as persistence layer
  • mongoose as database connector
  • ejs as very simple templating engine
  • expresso unit test


Lesson 01

Install all stuff via

brew install mongodb
brew install node

# or via source
git clone
cd node
make install

git clone
cd npm
sudo make install

npm install express mongoose jade

Run database with

mongod run --config /usr/local/Cellar/mongodb/1.6.5-x86_64/mongod.conf
  • generate a skeleton app in the current dir by typing express
  • run tests with expresso

Lesson 02

  • added logging
  • added CRUD stubs
  • implemented GET messages, POST message (finding, saving with mongodb)
  • hardened test harness

Lesson 03

  • added view to GET messages
  • could not get partials call work with ejs. Switching to jade template engine
  • pushing and putting objects to mongodb via mongoose
  • installed futon4mongo as AdminUI for mongodb
  • its very hard to get things right. the docs and especially the tutorials aren't up to date. Getting the arguments of callback functions right is hard.
