Jupyter-server-proxy config for running OpenRefine.

Open to Notebook homepage: Binder

Open to OpenRefine: Binder

Open to Jupyterlab: Binder

Early original work on getting OpenRefine running in MyBinder was done by @betatim (betatim/openrefineder) and @yuvipanda helped me get my head round various bits of jupyterhub/jupyter-server-proxy/ which is key to proxying web services via Jupyter. @manics PR for handling predefined, rather than allocated, port mappings also made life much easier...

This master branch demonstrates:

  • using serverproxy (traitlet definition) to add an OpenRefine menu option to the notebook start menu. The configuration uses a fixed port assigment so that we can work with the client package.
  • a button is also enabled and added to the JupyterLab launcher.

OpenRefine can now be started and launched from the notebook homepage New menu or from the JupyterLab launcher.

The OpenRefine client can be found on the openrefine path or on a path explictly via the predefined port (proxy/3333/).

Calling the path directly (eg starting MyBinder with the path openrefine, or adding ?urlpath=openrefine to the Bunder URL) will launch the Binder container directly into the OpenRefine GUI application.

Note that OpenRefine needs to be launched or otherwise started in order for it to be availagle to the Python Openrefine client.

There are several other branches in this repo that demonstrate other ways of working with OpenRefine in MyBinder/using repo2docker.

  • start: a simple setup that installs OpenRefine and autostarts it. This OpenRefine server can be accessed by the Python OpenRefine client (eg via the demo Jupyter notebook(s)) but the UI is not available;
  • simpleproxy: a container that installs and autoruns the OpenRefine server, and also makes it available as a proxied URL against known port (the port the OpenRefine server is explicitly started on);
  • setup: a script that uses the Python package method of installing the serverproxy extension, preconfigured for proxying OpenRefine.
  • traitlet-nolab: a simple traitlet definition that does not install an OpenRefine icon into the JupyterLab launcher.
You can’t perform that action at this time.
