This is a simple html based console that uses the bitmask.js library, which uses the REST api exposed by the HTTPRequestDispatcher. This html should be served when leap.bitmask_js package is not found on the import path from where bitmask.core is executed. The development of bitmask_js is in the ui/ folder in this bitmask-dev repo. A pre-compiled version of the whole html+js ui can be found in the leap.bitmask_js package. To have it served from the same endpoint than the REST api, just install leap.bitmask_js in your environment. This 'web console' remains here to be able to develop against the REST api without the need of installing the full-fledged bitmask_js package. However, it's only going to work when running from the git repository.
