As a developer using the NDS Labs platform, I should be able to easily edit and debug JavaScript code written using Node.js.

This encompasses both server-side and client-side JavaScript. Either case may have special concerns, for example, how to expose a port to allow external systems to access the running code (i.e. the developer's browser needs to hit the developer's http-server, a running UI needs to hit the developer's API server, etc)

Some useful features might include:

1. Linting
2. Running node / npm / bower / grunt / gulp / etc from command-line
3. Serving content via Node's http-server

Cloud9 seemed to be a good jumping-off point, offering #1 out-of-the-box.
Given the built-in terminal, #2 and therefore #3 should be fairly easy

This ticket can be closed when a suitable Node.js development environment has been packaged as an NDS Labs service spec pointing to a tagged Docker image (i.e. not "latest")
