+This is the Learning MFE (micro-frontend application), which renders all
+learner-facing course pages (like the course outline, the progress page,
+actual course content, etc).

+Development
+-----------
+
+Start Devstack
+^^^^^^^^^^^^^^
+
+To use this application, `devstack <https://github.com/edx/devstack>`__ must be running and you must be logged into it.
+
+- Run ``make dev.up.lms``
+- Visit http://localhost:2000/course/course-v1:edX+DemoX+Demo_Course to view the demo course.  You can replace ``course-v1:edX+DemoX+Demo_Course`` with a different course key.
+
+Local module development
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+To develop locally on modules that are installed into this app, you'll need to create a ``module.config.js``
+file (which is git-ignored) that defines where to find your local modules, for instance::
+
+   module.exports = {
+     /*
+     Modules you want to use from local source code.  Adding a module here means that when this app
+     runs its build, it'll resolve the source from peer directories of this app.
+
+     moduleName: the name you use to import code from the module.
+     dir: The relative path to the module's source code.
+     dist: The sub-directory of the source code where it puts its build artifact.  Often "dist", though you
+       may want to use "src" if the module installs React as a peer/dev dependency.
+     */
+     localModules: [
+        { moduleName: '@edx/paragon/scss', dir: '../paragon', dist: 'scss' },
+        { moduleName: '@edx/paragon', dir: '../paragon', dist: 'dist' },
+        { moduleName: '@edx/frontend-enterprise', dir: '../frontend-enterprise', dist: 'src' },
+        { moduleName: '@edx/frontend-platform', dir: '../frontend-platform', dist: 'dist' },
+     ],
+   };
+
+See https://github.com/edx/frontend-build#local-module-configuration-for-webpack for more details.
+
+Deployment
+----------
+
+The Learning MFE is similar to all the other Open edX MFEs. Read the Open
+edX Developer Guide's section on
+`MFE applications <https://edx.readthedocs.io/projects/edx-developer-docs/en/latest/developers_guide/micro_frontends_in_open_edx.html>`_.
+
+Environment Variables
+^^^^^^^^^^^^^^^^^^^^^
+
+This MFE is configured via environment variables supplied at build time.
+All micro-frontends have a shared set of required environment variables,
+as documented in the Open edX Developer Guide under
+`Required Environment Variables <https://edx.readthedocs.io/projects/edx-developer-docs/en/latest/developers_guide/micro_frontends_in_open_edx.html#required-environment-variables>`_.
+
+The learning micro-frontend also supports the following additional variables:
+
+SOCIAL_UTM_MILESTONE_CAMPAIGN
+  This value is passed as the ``utm_campaign`` parameter for social-share
+  links when celebrating learning milestones in the course. Optional.
+
+  Example: ``milestone``
+
+SUPPORT_URL_CALCULATOR_MATH
+  A link that explains how to use the in-course calculator. You can use the
+  one in the example below, if you don't want to have your own branded version.
+
+  Example: https://support.edx.org/hc/en-us/articles/360000038428-Entering-math-expressions-in-assignments-or-the-calculator
+
+SUPPORT_URL_ID_VERIFICATION
+  A link that explains how to verify your ID. Shown in contexts where you need
+  to verify yourself to earn a certificate. The example link below is probably too
+  edx.org-specific to use for your own site.
+
+  Example: https://support.edx.org/hc/en-us/articles/206503858-How-do-I-verify-my-identity
+
+SUPPORT_URL_VERIFIED_CERTIFICATE
+  A link that explains what a verified certificate is.  You can use the
+  one in the example below, if you don't want to have your own branded version.
+  Optional.
+
+  Example: https://support.edx.org/hc/en-us/articles/206502008-What-is-a-verified-certificate
+
+TWITTER_HASHTAG
+  This value is used in the Twitter social-share link when celebrating learning
+  milestones in the course. Will prefill the suggested post with this hashtag.
+  Optional.
+
+  Example: ``brandedhashtag``
+
+TWITTER_URL
+  A link to your Twitter account. The Twitter social-share link won't appear
+  unless this is set. Optional.
+
+  Example: https://twitter.com/edXOnline
+
+ENABLE_JUMPNAV
+  Enables the new Jump Navigation feature in the course breadcrumbs, defaulted to  the string 'true'.
+  Disable to have simple hyperlinks for breadcrumbs. Setting it to any other value but 'true' ('false','I love flags', 'etc' would disable the Jumpnav).
+  This feature flag is slated to be removed as jumpnav becomes default. Follow the progress of this ticket here:
+  https://openedx.atlassian.net/browse/TNL-8678

 Similarly, if the URL doesn't contain a unit ID, we use the `position` field of the sequence to determine which unit we want to display from that sequence.  If the position isn't specified in the sequence, we choose the first unit of the sequence.  After determining which unit to display, we update the URL to match.  After the URL is updated, the application will attempt to load that unit via an iFrame.

-(As an additional data point, djoy has stored data in this format in multiple projects over the years and found it to be very effective)
+Different modules of the application maintain individual/lists of IDs that reference data stored in the model store.  These are akin to indices in a database, in that they allow you to quickly extract data from the model store without iteration or filtering.  
+
+A common pattern when loading data from an API endpoint is to use the model-store's redux actions (addModel, updateModel, etc.) to load the "models" themselves into the model store by ID, and then dispatch another action to save references elsewhere in the redux store to the data that was just added.  When adding courses, sequences, etc., to model-store, we also save the courseId and sequenceId in the 'courseware' part of redux.  This means the courseware React Components can extract the data from the model-store quickly by using the courseId as a key: `state.models.courses[state.courseware.courseId]`.  For an array, it iterates once over the ID list in order to extract the models from model-store.  This iteration is done when React components' re-render, and can be done less often through memoization as necessary.

+# Naming API functions and redux thunks
+
+Because API functions and redux thunks are two parts of a larger process, we've informally settled on some naming conventions for them to help differentiate the type of code we're looking at.
+
+## API Functions
+
+This micro-frontend follows a pattern of naming API functions with a prefix for their HTTP verb.
+
+Examples:
+
+`getCourseBlocks` - The GET request we make to load course blocks data.
+`postSequencePosition` - The POST request for saving sequence position.
+
+## Redux Thunks
+
+Meanwhile, we use a different set of verbs for redux thunks to differentiate them from the API functions.  For instance, we use the `fetch` prefix for loading data (primarily via GET requests), and `save` for sending data back to the server (primarily via POST or PATCH requests)
+
+Examples:
+
+`fetchCourse` - The thunk for getting course data across several APIs.
+`fetchSequence` - The thunk for the process of retrieving sequence data.
+`saveSequencePosition` - Wraps the POST request for sending sequence position back to the server.
+
+The verb prefixes for thunks aren't perfect - but they're a little more 'friendly' and semantically meaningful than the HTTP verbs used for APIs.  So far we have `fetch`, `save`, `check`, `reset`, etc.

+# Testing
+
+## Status
+Draft
+
+Let's live with this a bit longer before deciding it's a solid approach and marking this Approved.
+
+## Context
+We'd like to all be on the same page about how to approach testing, what is
+worth testing, and how to do it.
+
+## React Testing Library
+We'll use react-testing-library and jest as the main testing tools.
+
+This has some implications about how to test. You can read the React Testing Library's
+[Guiding Principles](https://testing-library.com/docs/guiding-principles), but the main
+takeaway is that you should be interacting with React as closely as possible to the way
+the user will interact with it.
+
+For example, they discourage using class or element name selectors to find components
+during a test. Instead, you should find them by user-oriented attributes like labels,
+text, or roles. As a last resort, by a `data-testid` tag.
+
+## Mocking data
+We'll use [Rosie](https://github.com/rosiejs/rosie) as a tool for building JavaScript objects.
+Our main use case for Rosie is to use factories in order to mock the data we'd like to fetch when rendering components.
+[axios-mock-adapter](https://www.npmjs.com/package/axios-mock-adapter) allows us to mock the response of an HTTP request.
+
+For example, we may use a factory to build a course metadata object:
+
+`const courseMetadata = Factory.build('courseMetadata');`
+
+Then we'd pass that `courseMetadata` object into an axios mock call:
+
+`axiosMock.onGet('example.com').reply(200, courseMetadata);`
+
+This way, when a component sends a GET request to `example.com` within the test's lifecycle, the request will be intercepted
+by the axios-mock-adapter, and the courseMetadata object will be returned.
+
+These factories should live within the data directories they intend to mock
+```
+courseware
+  | data
+      | __factories__
+          | courseMetadata.factory.js /* used to define the Rosie factory */
+      | api.js /* getCourseMetadata() lives here */
+```
+
+## What to Test
+We have not found exhaustive unit testing of frontend code to be worth the trouble.
+Rather, let's focus on testing non-obvious behavior.
+
+In essence: `test behavior that wouldn't present itself to a developer playing around`.
+
+Practically speaking, this means error states, interactive components, corner cases,
+or anything that wouldn't come up in a demo course. Something a developer wouldn't
+notice in the normal course of working in devstack.
+
+## Snapshots
+In practice, we've found snapshots of component trees to be too brittle to be worth it,
+as refactors occur or external libraries change.
+
+They can still be useful for data (like redux tests) or tiny isolated components.
+
+But please avoid for any "interesting" component. Prefer inspecting the explicit behavior
+under test, rather than just snapshotting the entire component tree.

+# Liberal courseware path handling
+
+## Status
+
+Accepted
+
+_This updates some of the content in [ADR #2: Courseware page decisions](./0002-courseware-page-decisions.md)._
+
+## Context
+
+The courseware container currently accepts three path forms:
+
+1. `/course/:courseId`
+2. `/course/:courseId/:sequenceId`
+3. `/course/:courseId/:sequenceId/:unitId`
+
+Forms #1 and #2 are always redirected to Form #3 via simple set of rules:
+
+* If the sequenceId is not specified, choose the first sequence in the course.
+* If the unitId is not specified, choose the active unit in the sequence,
+  or the first unit if none are active.
+
+Thus, Form #3 is effectively the canonoical path;
+all Learning MFE units should be served from it.
+We acknowledge that the best user experience is to link directly to the canonoical
+path when possible, since it skips the redirection steps.
+Still, there are times when it is necessary or prudent to link just to a course or
+a sequence.
+
+Through recent work in the LMS, we are realizing that there are _also_ times where it
+would be simpler or more performant to link a user to an
+_entire section without specifying a squence_ or to a
+_unit without including the sequence_.
+Specifically, this capability would let as avoid further modulestore or
+block transformer queries in order to discern the course structure when trying to
+direct a learner to a section or unit.
+Futhermore, we hypothesize that being able to build a Learning MFE courseware link
+with just a unit ID or a section ID will be a nice simplifying quality for future
+development or debugging.
+
+## Decision
+
+The courseware container will accept five total path forms:
+
+1. `/course/:courseId`
+2. `/course/:courseId/:sectionId`
+3. `/course/:courseId/:sectionId/:unitId`
+4. `/course/:courseId/:sequenceId`
+5. `/course/:courseId/:unitId`
+6. `/course/:courseId/:sequenceId/:unitId`
+
+The redirection rules are as follows:
+
+* Forms #1 redirects to Form #4 by selecting the first sequence in the course.
+* Form #2 redirects to Form #4 by selecting to the first sequence in the section.
+* Form #3 redirects to Form #5 by dropping the section ID.
+* Form #4 redirects to Form #6 by choosing the active unit in the sequence
+  (or the first unit, if none are active).
+* Form #5 redirects to Form #6 by filling in the ID of the sequence that the
+  specified unit belongs to (in the edge case where the unit belongs to multiple
+  sequences, the first sequence is selected).
+
+As before, Form #5 is the canonocial courseware path, which is always redirected to
+by any of the other courseware path forms.
+
+## Consequences
+
+The above decision is implemented.
+
+## Further work
+
+At some point, we may decide to further extend the URL scheme to be
+more human-readable.
+
+We can't make UsageKeys themselves more readable because they're tied to student state,
+but we could introduce a new optional `slug` field on Sequences,
+which would be captured and propagated to the learning_sequences API.
+We could eventually do something similar to Units, since those slugs only have to be sequence-local.
+
+So eventually, URLs could look less like:
+
+```
+
+https://learning.edx.org/course/course-v1:edX+DemoX.1+2T2019/block-v1:edX+DemoX.1+2T2019+type@sequential+block@e0a61b3d5a2046949e76d12cac5df493/block-v1:edX+DemoX.1+2T2019+type@vertical+block@52dbad5a28e140f291a476f92ce11996
+```
+
+And more like:

+# Direction of Courseware APIs
+
+In order to allow for greater flexibility and separation of concerns, we're going to stop using the Course Blocks API for navigational data, and pull that data from the Learning Sequences Outlines API instead. The intention is to give us four distinct layers of courseware that can eventually be composed in different ways:
+
+* Learning Context Metadata
+* Learning Context Navigation
+* Sequence Navigation
+* Unit Rendering
+
+Note that "Learning Context" is a generalization of "Course" that includes other things like Content Libraries, Learning Pathways, and potentially other logical groupings of content.
+
+This is a refinement of [0002-courseware-page-decisions.md](0002-courseware-page-decisions.md). The fundamental layers remain the same, but this document tries to better clarify the boundaries and path forward for these layers. We're not making these layers completely swappable/pluggable now, but we should separate the data access in a way that allows for that in the future.
+
+## Background
+
+We currently make four primary requests to the LMS when rendering courseware instructional content:
+
+1. Course Metadata: `/api/courseware/course/{courseId}` (REST API)
+2. Course Blocks API: `/api/courses/v2/blocks/?course_id={courseId}` (REST API)
+3. Sequence Metadata: `/api/courseware/sequence/{sequenceUsageKey}` (REST API)
+4. Unit: `/xblock/{unitBlockUsageKey}` (rendered in an iframe)
+
+There is a significant amount of overlap between the Course Blocks API and the others at the moment, since Course Blocks takes a static snapshot of the entire tree of course content at once. There are a few problems with the current arrangement:
+
+* It's slow and complex. The Course Blocks API can be difficult to maintain and reason about, and trickier to optimize.
+* Assuming that all course structures are the same makes it difficult to support other content types, like LabXchange Learning Pathways or adaptive content.
+* The overlap between Course Blocks and the other APIs means that there can be conflicts about the state.
+
+## Motivating Vision
+
+We have seen a desire to extend or enhance the courseware experience in various ways:
+
+Learning Context Navigation
+* Allowing for shorter, human-readable URLs in courseware.
+* Smaller courses that do not need the current navigational hierarchy.
+* LabXchange pathways.
+
+Sequence Navigation
+* Adaptive content, where the full list of units is not known up front.
+* More limited navigation, where content is pushed linearly, without the ability to jump ahead.
+* Different layouts for content browsing.
+
+Unit Rendering
+* Use of QTI content (currently serviced by cc2olx conversion).
+* Desire to experiment with a next-gen version of XBlock.
+* Use of entirely LTI units.
+
+The idea would be to insulate each layer from the layers above and below it. Sequence rendering shouldn't be affected by whether or not it's in a two level hierarchy (Course → Section → Sequence), or a flat one (Course → Sequence). Learning Context Navigation should be able to reference Sequences without caring if a Sequence is an adaptive one or not. Sequences should be able to have a common interface to call Unit iframes, whether those Units are rendering XBlocks or QTI content.
+
+Note that supporting these types of course structures would require downstream changes in other systems as well (e.g. analytics).
+
+## Next Step: Removing use of the Course Blocks API.
+
+The next step in this process is to remove the call to the Course Blocks API, and split its responsibilities across just the existing Learning Sequences Outline and Sequence Metadata APIs. This will involve at least a couple of steps.
+
+### Complete rollout of Learning Sequences Outline calls.
+
+We're currently in a transitional state between these APIs where the Learning Sequences Outline calls are only rolled out on a small handful of courses.
+
+### Shift Sequence and Unit metadata to only come from Sequence Metadata API.
+
+We currently pull this information from both Course Blocks and the Sequence Metadata API. We can consolidate on just the Sequence Metadata API. There is also server side optimization that can be done with the Sequence Metadata API calls as part of this work.
