Want to know the big picture about what is going on inside Galaxy? This workshop will give participants a practical introduction to the Galaxy code base with a focus on changing those parts of Galaxy most often modified by local deployers and new contributors. 

The workshop will include the following specific content:

  • A description of the various file and top-level directories in the Galaxy code base.
  • An overview of important Python modules - including models, tools, jobs, workflows, visualizations, and API controllers.
  • An overview of important Python objects and concepts in the Galaxy codebase - including the Galaxy transaction object ("trans"), the application object ("app") , and the configuration object ("config").
  • An overview of various plugin extension points.
  • An overview of important JavaScript modules that power the front-end.
  • An overview of important JavaScript concepts used by Galaxy - in particular RequireJS, Backbone MVC, and grunt.
  • An overview of the client build system used to generate compressed JavaScript, cascading stylesheets, and other static web assets.
  • A demonstration of a complete start-to-finish modification of Galaxy - including forking the project on Github, modifying files, running the tests, checking style guidelines, committing the change, pushing it back to your local Github fork, and opening a pull request.
  • A brief description of other projects in the Galaxy ecosystem (CloudMan, the Tool Shed, bioblend, docker-galaxy-stable, Pulsar, and Planemo).


  • A general knowledge of Galaxy (for example, you should be familiar with the material in Galaxy 101 or have attended Introduction to Galaxy).
  • Comfort with scripting programming languages (Python and JavaScript will be the most helpful).
