* Bumping axios-mock-adapter version
Thought there was a feature in 1.18.2 that I needed - turns out the feature hasn’t been released yet. Still fine to bump the dependency, though.
* Hiding some warnings about console logging.
* Fixes bugs in CoursewareContainer
Fixes a few bugs in the courseware container:
- Position was not being saved because we weren’t reading “saveUnitPosition” correctly.
- We weren’t calling checkContentRedirect with the right arguments - it was using a non-existent unitId instead of the routeUnitId, meaning we would redirect to the active unit even if a unit was specified in the URL.
Adds tests in CoursewareContainer for various URL and data states.
Now explicitly tests:
- Exam redirects
- The resume block method when it has, and doesn’t have, a block to resume.
- The content redirect when a unit isn’t present on the URL (uses sequence.position)
- Loading a specific unit (not the first of a sequence!) by URL.
Updated some of the factories to be more flexible/allow multiple units.
Tracking analytics for onClick events in the Course Tool widget.
Extra: Fixed intl error in the Course Dates widget.

* fix: Use reselect’s defaultMemoize instead of lodash.memoize
Lodash memoize doesn’t examine all parameters when deciding to memoize, apparently, meaning it doesn’t re-call the function if any parameter except the first changes.

* Fixing test setup. Improper use of sequenceMetadata factory!
Two problems:
One, we weren’t properly passing the courseId into our sequenceMetadata factories, so it was differing than the one defined in courseMetadata. This didn’t manifest until now because we weren’t using the one from sequenceMetadata until this memoization fix!
Two, I’d updated the options for sequenceMetadata to have a “unitBlocks” option, but didn’t update all the usages of the old “unitBlock” option. This meant it was manually creating its own unit instead of inheriting the one from courseBlocks, resulting in a different ID.
I find it much more legible this way.
Some thoughts… as part of refactoring it, I made some of the redux selectors more formal, and made use of reselect more thoroughly. this resulted in a reduction in re-renders from 16 to 12 on your average page load. It’s also a bit more verbose, accounting for some of the increased line count.
I hadn’t tried it before, but found the memoize method of comparing previous props/state to current props/state to be very, very nice. Much easier than manually comparing props, and much clearer to me than using react hooks’ dependency arrays.
The lack of dependency arrays feels really freeing in general to me. They’ve been such a source of hard-to-track-down bugs, and the hooks linter does not always suggest the right solution for what belongs in and out of the array.
Function names are nice. We had a ton of custom hooks in there so that we could put names to otherwise anonymous bits of functionality.
Also note: this component has a test suite. It passed without any changes. 🥳
