Preview site not in MFE · Issue #1455 · openedx/frontend-app-learning

This is the only thing blocking the removal of legacy Courseware Sequence view. But to remove this, we would need to one of several things, none of which would be trivial:

Deprecate the Preview feature
- (improve Studio enough so that it is a sufficient preview?)
- what features would we lose here?
  - testing masquerading
  - testing nav as a student
Change the read-optimized LMS data (block structure, learning_sequences, edx-when, course overviews) so that they expose Draft data for the Learning MFE to consume.
Migrate courses over to Learning Core, which provides a better view of Draft content which the Learning MFE could consume.

This is low hanging fruit! We just need to make a course home tab view that iframes in the CustomTabBlock, which is just an HtmlBlock subclass!

This is the endpoint that renders a “chromeless” (nav-free) xblock.

This will never be removed entirely but, eventually, we can seriously simplify it to the point where it’s just a thin wrapper around the next item (built-in XBlock views).

Reference: What MFEs are there?

The full list of Open edX MFEs, including ones that are experimental or under development, can be found by searching “frontend-app-” in the openedx GitHub org: https://github.com/orgs/openedx/repositories?q=frontend-app-

The list of Open edX MFEs that run out-of-the-box in Tutor can be found by looking at the CORE_MFE_APPS variable in the tutor-mfe plugin’s plugin.py file:

[upcoming release / tutor nightly] https://github.com/overhangio/tutor-mfe/blob/nightly/tutormfe/plugin.py#L33
[latest release / tutor master] https://github.com/overhangio/tutor-mfe/blob/master/tutormfe/plugin.py#L33

Reference: MFE Base URLs

MFEs follow a simple naming pattern. Given some lowercase hyphen based name{APPNAME} (for example, learning)….

The repo is https://github.com/openedx/frontend-app-{APPNAME}
- Example: https://github.com/openedx/frontend-app-learning
The base URL in Tutor is https://apps.{LMS}/{APPNAME}
- Example: https://apps.myopenedx.site/learning
The base URL on edX is https://{APPNAME}.edx.org
- Example: https://learning.edx.org
- EXCEPTION: For learner-dashboard, the URL is not https://learner-dashboard.edx.org. Instead, it’s https://home.edx.org.
