Walkthrough

This pull request adds a new resolver method, communityInvitationsCount, which validates the requesting user's agent info and retrieves the count of community invitations via a service call. In addition, the existing spaceMembershipsHierarchical method is updated to accept an optional limit argument, limiting the number of spaces returned. On the service side, a new getCommunityInvitationsCountForUser method is introduced, and the handling of level zero spaces in getCommunityMembershipsHierarchical is adjusted accordingly.

Changes

File(s) Summary of Changes
src/services/api/me/me.resolver.fields.ts - Added new method communityInvitationsCount with validation and GraphQL guards.
- Modified spaceMembershipsHierarchical to accept an optional limit parameter and pass it to the service layer.
src/services/api/me/me.service.ts - Introduced new method getCommunityInvitationsCountForUser to obtain invitation counts.
- Updated getCommunityMembershipsHierarchical to support an optional limit for filtering level zero spaces.
- Adjusted variable naming for filtered spaces (using levelZeroSpacesRaw).

  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

58-83: Add input validation for states array.

While the userID validation is good, consider adding validation for the states array to ensure it contains valid state values.

 public async communityInvitationsCount(
   @CurrentUser() agentInfo: AgentInfo,
   @Args({
     name: 'states',
     nullable: true,
     type: () => [String],
     description: 'The state names you want to filter on',
   })
   states: string[]
 ): Promise<number> {
   if (agentInfo.userID === '') {
     throw new ValidationException(
       'Unable to retrieve invitations as no userID provided.',
       LogContext.COMMUNITY
     );
   }
+  if (states?.length > 0) {
+    const validStates = ['pending', 'accepted', 'rejected']; // Add your valid states here
+    const invalidStates = states.filter(state => !validStates.includes(state));
+    if (invalidStates.length > 0) {
+      throw new ValidationException(
+        `Invalid states provided: ${invalidStates.join(', ')}`,
+        LogContext.COMMUNITY
+      );
+    }
+  }
   return this.meService.getCommunityInvitationsCountForUser(
     agentInfo.userID,
     states
   );
 }

185-198: Use immutable array operations for limiting spaces.

The current implementation modifies the original array using splice. Consider using slice instead to avoid potential side effects.

   const levelZeroSpacesRaw = this.filterSpacesByLevel(
     sortedFlatListSpacesWithMembership,
     SpaceLevel.L0
   );
+  const limitedLevelZeroSpaces = limit
+    ? levelZeroSpacesRaw.slice(0, limit)
+    : levelZeroSpacesRaw;
-  if (limit) {
-    levelZeroSpacesRaw.splice(limit);
-  }

🛠️ Refactor suggestion

Optimize count retrieval for better performance.

The current implementation fetches all invitations just to get the count. Consider adding a dedicated count method in rolesService to avoid fetching unnecessary data.

 public async getCommunityInvitationsCountForUser(
   userId: string,
   states?: string[]
 ): Promise<number> {
-  const invitations = await this.rolesService.getCommunityInvitationsForUser(
+  return this.rolesService.getCommunityInvitationsCountForUser(
     userId,
     states
   );
-  return invitations.length;
 }
