This repository consists of three main components to assist in the creation of new XBlocks:
- a template-based generator for new XBlocks (found in the
prototype
directory) - sample XBlocks that can be the basis for new XBlock work (found in the
sample_xblocks
directory) - Workbench runtime, a simple runtime for viewing and testing XBlocks in a browser (found in the
workbench
directory)
This code runs on Python 3.11 or newer.
# Clone the repository git clone git@github.com:openedx/xblock-sdk.git cd xblock-sdk # Set up a virtualenv with the same name as the repo and activate it # Here's how you might do that if you have virtualenvwrapper setup. mkvirtualenv -p python3.11 xblock-sdk # Install system requirements needed to run this on ubuntu. # Note: Debian 10 needs libjpeg62-turbo-dev instead of libjpeg62-dev. sudo apt-get install python-dev libxml2-dev libxslt-dev lib32z1-dev libjpeg62-dev
Install the requirements and register the XBlock entry points:
$ make install
Run the Django development server:
$ python manage.py runserver
Open a web browser to: http://127.0.0.1:8000
Testing is done via tox to test all supported versions:
Create and activate a virtualenv to work in.
Run just unit tests via tox:
$ tox
For each supported version of Django (currently 1.8 and 1.11) this will run:
- Integration tests of XBlocks running within the workbench.
- Individual tests written for the demo XBlocks
To run the unit tests in your virtualenv you can use:
$ make test
To run all tox unit tests and quality checks:
$ make test-all
To run just the quality checks:
$ make quality
You can test XBlocks through a browser using Selenium. We have included an
example Selenium test for thumbs
that uses Django's LiveServerTestCase.
It runs as part of the test suite as executed by the above command.
To update and view test coverage:
$ make coverage
See the coverage.py docs for more info and options.
This repository is deployed to PyPI. To deploy a new version.
- Bump the version of the package in
workbench/__init__.py
- Make a new release in github or push a new tag up to Github.
The pypi-publish github action should trigger. It will build and deploy the source and wheel package to PyPI.
Start by going through the documentation. If you need more help see below.
If you're having trouble, we have discussion forums at https://discuss.openedx.org where you can connect with others in the community.
Our real-time conversations are on Slack. You can request a Slack invitation, then join our community Slack workspace.
For anything non-trivial, the best path is to open an issue in this repository with as many details about the issue you are facing as you can provide.

When you open the workbench, you'll see a list of sample XBlock configurations (scenarios). Each will display a page showing the XBlocks composited together, along with internal information like the "database" contents.
The workbench database defaults to a sqlite3 database. If you're using devstack,
you may want to set WORKBENCH_DATABASES
to point to your MySQL db.
If you want to experiment with different students, you can use a URL parameter to set the student ID, which defaults to 1:
http://127.0.0.1:8000/?student=17
Different students will see different student state, for example, while seeing the same content. The default student ID contains only digits but it is not necessary to limit student IDs to digits. Student IDs are represented as strings.
Making an XBlock involves creating a Python class that conforms to the XBlock
specification. See the sample_xblocks
directory for examples and
the XBlock tutorial for a full walk-through.
We provide a script to create a new XBlock project to help you get started.
Run bin/workbench-make-xblock
in a directory where you want to create your XBlock
project. The script will prompt you for the name of the XBlock, and will
create a minimal working XBlock, ready for you to begin development.
You can provide scenarios for the workbench to display: see the thumbs.py
sample for an example, or the xblock/problem.py
file. The scenarios are
written in a simple XML language. Note this is not an XML format we are
proposing as a standard.
Once you install your XBlock into your virtualenv, the workbench will automatically display its scenarios for you to experiment with.
If you are interested in making an XBlock to run for your course on edx.org, please get in touch with us as soon as possible -- in the ideation and design phase is ideal. See our XBlock review guidelines for more information (note that this is not needed for XBlocks running on your own instance of Open edX, or released to the wider community).
Included in this repository are some example XBlocks that demonstrate how to use various aspects of the XBlock SDK. You can see a more detailed description of those examples in the README located in that repository:
There is a rich community of XBlock developers that have put together a large number of XBlocks that have been used in various contexts, mostly on the edx-platform. You can see examples of what that community has done in the edx-platform wiki.
