This repository is mainly about client-side javascript, the version
of Node.js used for the build scripts doesn't really matter.
One of the dependencies in package.json uses the '^x.x' syntax in
its sub-dependencies and isn't supporteed on Node.js 0.8, which
is why the Travis CI build is currently erroring on the install step.
This library is supposed to be hosted outside WMF gerrit. So adding a
build, test system.
* Add js lint and css lint
* minifier for css and js
* css lint does not pass now.
