We will mainantain homogenaity in our development environment by using a linter that will automaticly conform code to a pre-defined style, and by using gulp (a JavScript compiler), which will combine different modules and files into the distrobution file. Our code will be kept in sync using git.
We will use a vagrant box to develop the server. Even though node and npm already do a lot to manage versions of dependencies, this will allow us to manage the version of node itself. This will also allow us to set up a local Mongo database instance easily.
