Summary

This diff handles creating the screen that will display all roles in a given community, alongside a count of how many members are assigned each role. There is also a button that will allow admins to create a new role - the functionality of the button will be implemented in the next diff. The designs for this screen can be found on the Figma.

Note: For now, I pull the threadInfo directly from the navigation params, but in a later diff I plan to pull the updated threadInfo from the redux store (a solution discussed in my 1:1 with Ashoat) in order to make sure the roles list is always kept up to date as new roles are added and users are navigated back to this screen. This will need to be done after the screen for creating a custom role is complete, so that's why it's going to be implemented later.

Depends on D8358

ENG-4168.

Test Plan

Confirm that for communities, the correct roles and role counts show up in the new screen. Also verified that for communities with several custom roles, the scroll container looks fine.

Couple of suggestions inline. Only one that's blocking this diff from being accepted is the use of \n\n for layout, let's break that text apart and use eg padding/margin/etc to lay things out properly.

I wonder if getRoleMemberCounts or getRoleMemberCountsForThread would be a more precise name?

1597–1613 ↗(On Diff #28214)

Not a huge deal, but could we include mapping roleIDs to roleNames within this loop to simplify things?

1601 ↗(On Diff #28214)

Should we annotate type here to improve readability a bit?

1603–1613 ↗(On Diff #28214)

Could this loop be simplified to something like:

threadInfo.members.forEach(({ role: roleID }) => {
  invariant(roleID, 'Community member should have a role');
  const roleName = roleIDsToNames[roleID];

  roleNamesToMemberCount[roleName] =
    (roleNamesToMemberCount[roleName] ?? 0) + 1;
});

39–45 ↗(On Diff #28214)

When I see a big clump of JSX being pushed to a list like this, I wonder if that clump of JSX should be a separate component?

Whatever you think is best, clearest, easiest to maintain, etc

65 ↗(On Diff #28214)

Using multiple newline characters (or <br />s) for layout is a red flag.

Would be better to separate these chunks of text into separate <Text> components and use margin/padding/etc to space things out properly.

This text will be placed on a purple background (the create role button), so this should be portable on both light/dark mode

Ah, my bad – looks like this is fine. Are the others still concerning, or are those cases similar?

Let's fix the rolePanelNameEntry color and the rolePanelCountEntry. Sorry should have caught this in my first round of review

The others should be fixed, requesting changes for this rn

whiteText --> panelForegroundLabel (sorry should've caught this earlier myself)

Reduce rolePanelList max height

Can we remove the Type suffix from this type name?

native/roles/community-roles-screen.react.js
135 ↗(On Diff #28560)

Is this whiteText fine in both light and dark mode?

native/roles/role-panel-entry.react.js
20 ↗(On Diff #28560)

Given that we're in the role-panel-entry component, we could probably just name this something like name and styles.rolePanelCountEntry something like count?

Whatever naming convention you prefer, doesn't really matter

Yeah, we're ok here since it's always on a purple button (the createRoleButton style right above this)
