This is Parametric RC Parts. Install by running npm install and bower install, this will install dependencies in folders node_module and bower_components. Use npm start to run using package.json start property, which is set to use the package always to run app.js, it restarts the process automatically and listens for file changes.
Docco is used for generating documentation, it simply uses the comments in the code. It can be installed using npm install -g docco and used like docco file.js.
JSlint can be used to regularly check code quality, either on www.jslint.com or by npm install -g jslint and subsequently jslint file.js, though I'm not sure how useful this is.
When installing on Ubuntu, two things need to be installed: Node.js and MongoDB. Install Node.js (and implicitly npm) using these instructions (official). Then install MongoDB using these (official) installation instructions.
For making backups, it might be useful to use LVM (mongodb instructions) to make a snapshot and then download that using FTP. For FTP on Ubuntu, vsftpd can be used.
Fancy term, but it works great. If you first specify behaviour and then implement it, it's much easier to see what you've done and to fix stuff. I use Jasmine for this. The tests can be found in the folder /spec. I use dummy data objects to test the database. Frontend testing can be done with Casper, but I think that just browser-testing the front-end will work just fine. For the backend however, it's damn handy.
I started using Stylus as CSS preprocessor. Its syntax is similar to Jade, and those are both similar to Python. It is integrated into the Node app and re-compiles the .styl file on each first request, or on each request (using the forced option).
The 'CADview' class in CADview.js contains all functionality for retrieving and rendering a part from part/PARTID/threejson. It uses Three.js to do this. Packaging this functionality in a module enables easy re-use and eventually open-sourcing. Future features can include: toggling wireframe view, a model composition tree with checkboxes to turn parts of the model on/off, reflective shading, and other stuff. Maybe the best philosophy is to try and come close to a CAD view. That means enabling the user to have the most accurate interpretation of the object's geometry and size.
