When starting with a new node/express project there is a variety of tools available that help your development effort. I have started a new project and want to write down my recommendations for the tools to use.
TL;TR; You can clone a github repo here and start right away.And see the build status on travis
NPM and package.json
Since you will have to manage dependencies in your node project, i advise you to start up with a package.json. This file contains the node modules you are using in your application. You might wanna exclude node_modules via the .gitignore file to avoid external node modules beeing checkied into git. You should now have a basic package.json file and a .gitignore file. Both need to be pushed to master right now.

After you installed express.js via npm and your package JSON you simply generate a Application Skeleton via the express command line tool. Now you have the skeleton application and push this to git. You might wanna add jade to your dependencies.

Mocha is a nice Unit Test framework. You want to use it for your TDD efforts. You can integrate this nicely into your grunt.js file to combine linting of js files and unit tests. Mocha and its commandos need a little tuning in the grunt.js template in order to make it stop complaining about unknown globals

Supertest Github repo
In order to let all your tests run as soon as you have pushed to your git you might wanna setup a travis ci build. Just connect travis to your repo and add .travis.yml file.
This is a superfast development chain that will help you to get superfast at implementing features into your app. The Setup time of ca. 20 Minutes will help a lot of time.
