Resource discovery: Implement folder card

[MisRob]

Blocked by

• New component: Initial implementation of KCard component kolibri-design-system#625 (however, since the PR is nearly ready, can be developed in parallel locally via Running Kolibri with local Kolibri Design System)

Summary

In support of coach resource discovery, we need to implement a new folder card. This will be one of the first cards in Kolibri built on top of KCard.

The final card is expected to look like:

It needs to show:

• Folder title
• Folder icon and label
• Folder thumbnail picture
• Folder thumbnail placeholder when a picture is not available

References

• Resource discovery designs (see folder cards)
• Card specs designs
• Coach Resource Discovery #11888
• Sibling cards: Resource discovery: Implement channel card #12317, Resource discovery: Implement resource card #12319

Guidance

• Create a completely new component <AccessibleFolderCard> and use <KCard> as its basis
• Regarding the structure of production data that the card should display, examine existing folder cards in the Library and also see the useSearch composable. In the scope of this issue, assume that data for the new card will have the same structure.
• For the purpose of development and review, display the new card at any place in Kolibri and remove the preview shortly before the final merge. It may be handy to work on the Library page because it has access to all data.
• Even though any of the existing cards shouldn’t be changed, they may contain some useful pieces of code for the new card so it’s recommended to examine them (see ResourceCard.vue when contentNode.is_leaf is false)
• It is possible that KCard will need further updates to support all Kolibri cards. If there’s something that KCard doesn’t support yet, discuss with relevant people and determine next steps.

Out of scope

• Anything grid-related (this includes the card’s min and max width which will be the grid’s responsibility, as well as checkboxes)
• Refactoring existing card components in Kolibri
• Implementing other parts of the coach resource discovery such as the side panel where cards will be displayed

Acceptance criteria

• The card is built on top of the KCard and contains elements listed above
• It follows the designs closely (or discrepancies get discussed)
• It is content tolerant (renders well for short strings, long strings, missing information, missing thumbnail picture, etc.)
• It is responsive
• It supports RTL (note that KCard will be responsible for basic layout RTL support, but some additional tweaks may be needed for content that is provided to it via slots etc.)
• It is ready to receive production data, meaning it doesn’t use hardcoded data inside the card but rather receives data from outside like it would in the final feature, for example in the form of an object passed via prop (or any other relevant manner)
• For the purpose of preview and QA, please include at least a couple of <AccessibleFolderCard>'s in <ul> and feed them with data that have the same structure as production data and enough variance (see content tolerance criteria)
• If some components used in the current cards are re-used in this new card and tweaked for the purpose, there are no regressions in the old cards
