React XBlock Demo

Developing with Tutor

The recommended way to test and develop this XBlock is to install it into a Tutor devstack:

tutor mounts add .
tutor images build openedx-dev

Then you can go to http://studio.local.openedx.io:8001/ , add react_xblock_6 to a course's "Advanced module list", then add this block to a course and test it there. When you make changes to the code, Studio will automatically reload.

If the XBlock is not appearing, you may need to run this command and then restart the CMS+LMS containers. At the moment, it's unclear why this is necessary, but it seems that the install that happens during the image build is not properly creating the egg info and entry point.

tutor dev exec cms pip install -e /mnt/xblock-react-5/

Editing the React frontend code

The main file for the XBlock's user interface is react_xblock_2/frontend/src/react_xblock_2.tsx. But in order to edit this file, you will first have to install the required Node packages and start the frontend compiler:

cd react_xblock_2/frontend/
npm install
npm run watch

Translating

Internationalization (i18n) is when a program is made aware of multiple languages. Localization (l10n) is adapting a program to local language and cultural habits.

This XBlock is set up to use react-intl for internationalization and localization. It assumes that you will keep all translatable strings in the React frontend code, marked with <FormattedMessage> and the other components provided by react-intl. The ability to localize strings in the python code is not included, so put all your user-visible strings in the frontend. If you do turn out to need localization in the python backend, there are examples available separately for how to do this. See edx-developer-guide for more information.
