It was early days, yeah. The other part of the project that's been depreciated now was running node 0.4, if I am not mistaken. The watermap was part of a bigger asset tracking system, node + jade templating (before jade became pug, even). The watermap was actually embedded in a jade template, but when I depreciated the other system, I ended up just copy and pasting the output from the jade file into an index.html, and everything just kept working :D
