Refactor conversation list components to use granular data fetching hooks and add skeleton loading states for security line performance

The conversation list system has been refactored to use more granular data fetching hooks instead of loading complete conversation objects, reducing unnecessary API calls and improving performance. Key changes include:

📍Where to Start

Start with the conversation list screen components in features/conversation/conversation-list/conversation-list.screen.tsx to see how the new useConversationType hook and skeleton loading states are implemented.

Poem

Hopping through code with nimble delight,
Groups and DMs now shine so bright.
Skeletons shimmer while data loads in,
Consent and members fetched with a grin.
Refactored, renamed, and now so spry—
This rabbit’s code leaps ever high!

features/conversation/conversation-list/conversation-list-item/conversation-list-item-skeleton.tsx (2)

6-8: Consider adding proper TypeScript typing.

The component lacks explicit return type annotation which could improve code documentation and IDE support.

-export const ConversationListItemSkeleton = memo(function ConversationListItemSkeleton() {
+export const ConversationListItemSkeleton = memo(function ConversationListItemSkeleton(): JSX.Element {

10-55: Extract inline styles for better maintainability.

The component uses extensive inline styles which makes it harder to maintain and reuse. Consider extracting styles to a separate style object or using a styling solution.

Here's how you could refactor to use extracted styles:

+const useSkeletonStyles = () => {
+  const { theme } = useAppTheme()
+  const { listItemHeight } = useConversationListItemStyle()
+  
+  return {
+    container: {
+      flexDirection: "row" as const,
+      alignItems: "center" as const,
+      padding: theme.spacing.md,
+      height: listItemHeight,
+    },
+    avatar: {
+      width: theme.avatarSize.lg,
+      height: theme.avatarSize.lg,
+      borderRadius: theme.avatarSize.lg / 2,
+      backgroundColor: theme.colors.fill.secondary,
+      marginRight: theme.spacing.md,
+    },
+    textContainer: { flex: 1 },
+    titleLine: {
+      width: "70%",
+      height: 16,
+      backgroundColor: theme.colors.fill.secondary,
+      borderRadius: 4,
+      marginBottom: theme.spacing.xs,
+    },
+    subtitleLine: {
+      width: "50%",
+      height: 14,
+      backgroundColor: theme.colors.fill.tertiary,
+      borderRadius: 4,
+    },
+  }
+}

 export const ConversationListItemSkeleton = memo(function ConversationListItemSkeleton() {
-  const { theme } = useAppTheme()
-  const { listItemHeight } = useConversationListItemStyle()
+  const styles = useSkeletonStyles()

   return (
-    <View
-      style={{
-        flexDirection: "row",
-        alignItems: "center",
-        padding: theme.spacing.md,
-        height: listItemHeight,
-      }}
-    >
+    <View style={styles.container}>
       {/* Avatar skeleton */}
-      <View
-        style={{
-          width: theme.avatarSize.lg,
-          height: theme.avatarSize.lg,
-          borderRadius: theme.avatarSize.lg / 2,
-          backgroundColor: theme.colors.fill.secondary,
-          marginRight: theme.spacing.md,
-        }}
-      />
+      <View style={styles.avatar} />

       {/* Text content skeleton */}
-      <View style={{ flex: 1 }}>
+      <View style={styles.textContainer}>
         {/* Title line */}
-        <View
-          style={{
-            width: "70%",
-            height: 16,
-            backgroundColor: theme.colors.fill.secondary,
-            borderRadius: 4,
-            marginBottom: theme.spacing.xs,
-          }}
-        />
+        <View style={styles.titleLine} />

         {/* Subtitle line */}
-        <View

-            height: 14,
-            backgroundColor: theme.colors.fill.tertiary,
-            borderRadius: 4,
-          }}
-        />
+        <View style={styles.subtitleLine} />
       </View>
     </View>
   )
 })
features/conversation/conversation-requests-list/conversation-requests-list.screen-header.tsx (2)

11-14: Document the reason for disabling delete functionality.

The deletion feature appears to be temporarily disabled, but there's no explanation why. Consider adding a comment explaining the reasoning and timeline.

- // const { mutateAsync: deleteConversationsAsync, isPending } = useDeleteConversationsMutation()
+ // TODO: Delete functionality temporarily disabled for security line performance improvements
+ // const { mutateAsync: deleteConversationsAsync, isPending } = useDeleteConversationsMutation()

- // const { likelyNotSpamConversationIds, likelySpamConversationIds } =
- //   useConversationRequestsListItem()
+ // const { likelyNotSpamConversationIds, likelySpamConversationIds } =
+ //   useConversationRequestsListItem()

16-54: Consider feature flag instead of commenting out code.

The extensive commented code for the delete handler suggests this might be a longer-term change. Consider using a feature flag to cleanly disable the functionality while keeping the code maintainable.

+ const ENABLE_DELETE_FUNCTIONALITY = false // Feature flag
+
- // const handleDeleteAll = useCallback(
+ const handleDeleteAll = useCallback(
-   // () => {
+   () => {
+     if (!ENABLE_DELETE_FUNCTIONALITY) return
+     
-   //   Alert.alert(
+     Alert.alert(
       // ... rest of the function
-   // },
+   },
-   // [
+   [
-   //   // deleteConversationsAsync, likelyNotSpamConversationIds, likelySpamConversationIds
+     deleteConversationsAsync, likelyNotSpamConversationIds, likelySpamConversationIds
-   // ],
+   ],
- // )
+ )
features/xmtp/xmtp-conversations/xmtp-conversations-list.ts (1)

122-124: Remove redundant commented code.

The commented lines are now redundant since the same fields are enabled above. Clean up these comments to improve code readability.

-            // isActive: true,
-            // consentState: true, // We already get it when we convert to convos conversations
features/xmtp/xmtp-conversations/xmtp-conversations-dm.ts (1)

59-81: Good implementation with a type safety concern.

The function follows established patterns and has proper error handling. However, the type casting on line 74 could be unsafe.

Consider improving type safety:

-    return inboxId as unknown as IXmtpInboxId
+    return inboxId as IXmtpInboxId

The double casting through unknown suggests the types might not be compatible. Verify that dmPeerInboxId returns a type that's compatible with IXmtpInboxId.

components/group-avatar.tsx (1)

98-113: Refactoring improves modularity but consider performance implications.

The separation into three distinct hooks (useGroupMembers, useGroupName, useGroupImageUrl) improves code organization and reusability. However, this replaces a single query with multiple queries.

Consider whether these hooks implement proper caching and deduplication to avoid performance regressions. If the underlying queries aren't efficiently batched, this could result in multiple network requests where one was sufficient before.

features/groups/hooks/use-group-members.ts (1)

40-86: Consider simplifying the fallback logic.

The current implementation has complex interdependencies between queries and cache updates. Consider using React Query's dependent queries pattern or a single query with conditional data fetching.

Alternative approach using dependent queries:

export function useGroupMembers(args: {
  xmtpConversationId: IXmtpConversationId
  clientInboxId: IXmtpInboxId
  caller: string
  useFallback?: boolean
}) {
  const { xmtpConversationId, clientInboxId, caller, useFallback = true } = args

  return useQuery({
    queryKey: getReactQueryKey({
      baseStr: "groupMembersWithFallback",
      clientInboxId,
      xmtpConversationId,
    }),
    queryFn: async () => {
      // Try primary source first, then fallback
      const group = await getGroup({ clientInboxId, xmtpConversationId })
      if (group?.members) {
        return group.members
      }
      
      if (useFallback) {
        const xmtpMembers = await getXmtpGroupMembers({
          clientInboxId,
          xmtpConversationId,
        })
        return entify(
          xmtpMembers.map(convertXmtpGroupMemberToConvosMember),
          (member) => member.inboxId
        )
      }
      
      return undefined
    },
    meta: { caller },
  })
}

features/conversation/conversation-list/conversation-list-awaiting-requests.tsx (2)

12-12: LGTM: Performance optimization with better hook abstraction.

The switch from useConversationRequestsListItem to useConversationRequestsCount is a good performance optimization that fetches only the count when that's all that's needed.


19-23: LGTM: Simplified data destructuring aligns with the new hook.

The change from destructuring separate arrays to a single count value makes the code cleaner and more efficient.

features/conversation/conversation-requests-list/use-conversation-requests-count.ts (1)

1-25: LGTM: Well-designed hook with efficient data transformation.

This hook provides a clean abstraction for fetching conversation request counts. The use of the select function to transform the array to its length at the query level is efficient and prevents unnecessary re-renders.

The implementation correctly:

  • Uses useSafeCurrentSender() for proper error handling
  • Provides sensible defaults (count = 0)
  • Exposes appropriate loading states
  • Uses proper caller identification for debugging
features/conversation/conversation-requests-list/conversation-uncleared-requests.screen.tsx (2)

42-42: LGTM: Improved component naming for clarity.

The rename from ConversationRequestsListItem to ConversationListItemUncleared makes the component's purpose more explicit and specific.


51-73: LGTM: Consistent naming and caller string update.

The component definition and caller string are properly updated to match the new naming convention, maintaining consistency for debugging and logging purposes.

features/conversation/conversation-requests-list/use-conversation-requests-list-items.tsx (2)

5-8: LGTM: Added import for the new dedicated hook.

The import update correctly includes the new useUnknownConsentConversationsQuery hook alongside the existing options function.


22-25: LGTM: Simplified query usage with dedicated hook.

Replacing the manual useQuery call with the dedicated useUnknownConsentConversationsQuery hook improves code maintainability and reduces boilerplate while maintaining the same functionality and parameters.

features/conversation/conversation-list/conversation-list-item/conversation-list-item.tsx (2)

1-1: Good addition of useMemo import for performance optimization.

The import supports the style memoization being added in this component.


42-55: Excellent performance optimization with proper memoization.

The style memoizations are correctly implemented with appropriate dependencies:

  • Each memoized style includes the right dependencies (themed, screenHorizontalPadding, previewContainerStyle)
  • Prevents unnecessary style recalculations on every render
  • Maintains the same functionality while improving performance

This aligns well with the PR objective of "Security line performance" optimization.

features/conversation/conversation-list/conversation-list.component.tsx (5)

2-2: Good addition of useMemo import for performance optimization.


7-7: Good addition of style hook import for consistent sizing.

Using the centralized style hook ensures consistent list item height across the application.


20-20: Good use of centralized style hook.

Using listItemHeight from the style hook ensures consistency across components.


26-31: Excellent dynamic sizing optimization.

The memoized estimatedItemListSize calculation:

  • Dynamically adapts to screen dimensions and header height
  • Properly memoized with correct dependencies
  • Improves FlashList performance by providing accurate size estimates

This is a significant improvement over static sizing.


38-40: Good optimization of FlashList props.

Using the memoized values for estimatedItemSize and estimatedListSize will improve FlashList performance. The direct use of renderConversation also simplifies the component structure.

features/conversation/conversation-list/conversation-list.screen.tsx (4)

14-14: Good addition of skeleton component import.

The ConversationListItemSkeleton will provide better loading UX.


24-24: Good addition of optimized hook import.

The useConversationType hook is more efficient than fetching full conversation data.


101-109: Excellent performance optimization with improved UX.

The changes provide significant benefits:

  • useConversationType fetches only the conversation type instead of full conversation data
  • Reduces network overhead and improves performance
  • ConversationListItemSkeleton provides better loading experience instead of showing nothing
  • Aligns with the PR objective of performance optimization

This is a much more efficient data fetching strategy.


111-116: Simplified and cleaner conditional rendering logic.

The direct comparison with conversationType === "group" is more straightforward than the previous implementation and maintains the same functionality while being more readable.

features/blocked-conversations/blocked-conversations.screen.tsx (3)

34-34: Good component renaming for clarity.

The new name ConversationListItemBlocked is more descriptive and specific to its purpose.


47-47: Consistent component renaming.

The function name now matches the usage and provides better clarity about its purpose for blocked conversations.


57-57: Good update of caller string for debugging.

Updating the caller string to match the new component name maintains proper tracking and debugging capabilities.

Verify the timing of useEffectAfterInteractions.

The switch from useEffectOnce to useEffectAfterInteractions might affect when the query invalidation occurs. Ensure this timing change doesn't impact the user experience.


🏁 Script executed:

#!/bin/bash
# Description: Check if useEffectAfterInteractions is properly implemented and understand its timing
# Expected: Find the hook definition and usage patterns

Confirm delayed invalidation timing

The change from useEffectOnce (which runs immediately on mount) to useEffectAfterInteractions (which waits until after UI interactions/animations) may postpone when the cache is invalidated. Please verify that this delay won’t cause stale data or visible UI flicker. If you need the query invalidated as soon as the screen mounts, consider reverting to useEffectOnce or triggering the invalidation earlier.

✅ Verification successful

Well-structured function with proper error handling, but verify type casting safety.

The function follows the established patterns in this file with proper error handling and performance monitoring. However, the type casting on line 178 should be verified for safety.

The as unknown as IXmtpInboxId casting could potentially hide type mismatches. Can you verify that the creatorInboxId function actually returns a compatible type?


🌐 Web query:

What is the return type of the creatorInboxId function from @xmtp/react-native-sdk?

💡 Result:

The return type of the creatorInboxId function from @xmtp/react-native-sdk is Promise<InboxId>. This function is asynchronous and returns a promise that resolves to an InboxId, which is the unique identifier associated with the creator of a group within the XMTP messaging platform[1].

Approve casting: creatorInboxId returns compatible type

  • The creatorInboxId function from @xmtp/react-native-sdk returns a Promise<InboxId>, matching the base type of our IXmtpInboxId.
  • Applying as unknown as IXmtpInboxId merely adds the required brand symbol to the returned InboxId.

No changes required here.

features/groups/hooks/use-group-image-url.ts (1)

1-18: Well-implemented React hook following best practices.

The hook properly uses useQuery with the select option to extract only the needed property, includes appropriate null fallback handling, and follows React Query conventions.

features/groups/group.types.ts (1)

37-38: Good optimization making expensive properties optional for lighter conversation objects.

Making creatorInboxId and members optional allows for lazy loading of these potentially expensive properties, supporting the performance optimization goals mentioned in the PR. The explanatory comment for creatorInboxId is helpful.

features/xmtp/xmtp-consent/xmtp-consent.ts (1)

122-144: Well-implemented consent state retrieval function.

The function follows the established patterns in the file with proper error handling, duration wrapping, and consistent naming conventions. The implementation correctly uses the XMTP client's installation ID and handles errors appropriately.

features/xmtp/xmtp-conversations/xmtp-conversations-group.ts (3)

10-11: LGTM! Clean import additions.

The new imports for isGroupActive and listConversationMembers are properly added and support the new functionality.


180-200: LGTM! Well-implemented group members retrieval.

The function follows the established patterns in this file:

  • Consistent parameter structure with typed interfaces
  • Proper client retrieval and error handling
  • Performance monitoring with wrapXmtpCallWithDuration
  • Clear error messaging

This addition enhances the group management capabilities while maintaining code consistency.


362-384: LGTM! Consistent implementation for group active state.

The function maintains the same high-quality patterns as other functions in this file:

  • Proper typing and parameter destructuring
  • Consistent error handling with descriptive messages
  • Performance measurement wrapper
  • Clear return value handling

Great addition for checking group active status.

features/conversation/utils/convert-xmtp-conversation-to-convos-conversation.ts (6)

7-16: LGTM! Well-organized import additions.

The new imports properly support the enhanced functionality:

  • Consent state helper functions
  • Group and DM specific utilities
  • New group management functions

The imports are logically grouped and support the performance optimizations implemented below.


33-33: Good extraction for better readability.

Extracting the conversationClientInboxId improves code readability and reduces repetition in the subsequent Promise.all calls.


37-66: Excellent performance optimization with conditional fetching.

This refactoring introduces smart conditional fetching that only performs expensive operations (members, creator) when the conversation state is "allowed". This directly addresses the performance objectives mentioned in the PR title.

Key improvements:

  • Avoids heavy member and creator fetching for non-allowed conversations
  • Maintains fallback logic for consent and active states
  • Uses centralized last message retrieval

This is a well-thought-out optimization that balances functionality with performance.


82-84: Smart conditional members handling.

The conditional transformation of members only when present aligns well with the conditional fetching logic above. This prevents unnecessary processing and maintains type safety.


91-105: Consistent refactoring for DM conversations.

The DM conversation handling follows the same pattern improvements:

  • Centralized last message retrieval
  • Fallback logic for consent state
  • Clean Promise.all structure

Great consistency with the group conversation refactoring.


121-142: Well-designed helper function with smart fallback logic.

The getLastMessageForConversation function excellently centralizes the last message retrieval logic:

  • Prioritizes lastMessage from conversation object when available
  • Only performs expensive fallback message fetching for "allowed" conversations
  • Clear conditional flow that avoids unnecessary operations
  • Proper error boundaries with graceful fallback

This helper function embodies the performance optimization theme of this PR while maintaining robust functionality.

⚠️ Potential issue

Avoid side effects in render cycle - move cache update to useEffect.

The cache update is happening directly in the render cycle, which can cause performance issues and potential infinite re-renders. This violates React's principle of keeping renders pure.

Move the cache update to a useEffect:

+  React.useEffect(() => {
+    if (group && fallbackMembers && !group.members) {
+      setGroupQueryData({
+        clientInboxId,
+        xmtpConversationId,
+        group: {
+          ...group,
+          members: fallbackMembers,
+        },
+      })
+    }
+  }, [group, fallbackMembers, clientInboxId, xmtpConversationId])
+
-  // Update the group in cache when fallback members are fetched
-  if (group && fallbackMembers && !group.members) {
-    setGroupQueryData({
-      clientInboxId,
-      xmtpConversationId,
-      group: {
-        ...group,
-        members: fallbackMembers,
-      },
-    })
-  }
🤖 Prompt for AI Agents
In features/groups/hooks/use-group-members.ts around lines 68 to 77, the cache
update via setGroupQueryData is currently done directly in the render cycle,
causing side effects and potential infinite re-renders. To fix this, move the
cache update logic inside a useEffect hook that depends on group,
fallbackMembers, clientInboxId, and xmtpConversationId. This ensures the update
runs only when these dependencies change, keeping the render pure and avoiding
performance issues.

Optimize conversation list performance by splitting group data queries into granular hooks and reducing unnecessary data fetching

📍Where to Start

Start with the GroupAvatar component in components/group-avatar.tsx to see how the single group query has been split into three granular hooks, then review the conversation conversion utility in features/conversation/utils/convert-xmtp-conversation-to-convos-conversation.ts to understand the conditional data fetching optimization.

60-64: ⚠️ Potential issue

Fix inconsistent optional chaining usage.

Line 60 directly accesses updatedGroup.members.byId[inboxId] without optional chaining, which is inconsistent with the defensive patterns used elsewhere in this function and could cause runtime errors if members is undefined.

Apply this fix for consistency:

-        updatedGroup.members.byId[inboxId] = {
+        updatedGroup.members!.byId[inboxId] = {

Or alternatively, add a null check:

+        if (updatedGroup.members?.byId) {
          updatedGroup.members.byId[inboxId] = {
            inboxId,
            permission: "member",
            consentState: "unknown",
          }
+        }
🧹 Nitpick comments (1)
features/conversation/utils/find-conversations-by-inbox-ids.ts (1)

34-35: Remove redundant check after nullish coalescing.

Since group.members?.ids ?? [] guarantees groupMembersInboxIds will always be an array, the subsequent falsy check is redundant and can be removed.

  const groupMembersInboxIds = group.members?.ids ?? []
-  if (!groupMembersInboxIds) return false

44-48: Excellent defensive coding implementation!

The optional chaining and ternary operator correctly handle cases where group.members or group.members.byId might be undefined, preventing runtime errors while maintaining the original filtering logic.

features/conversation/conversation-requests-list/conversation-spam.query.ts (1)

37-42: Good defensive coding pattern!

The optional chaining and fallback to false when members.byId is undefined correctly handles missing member data while preserving the original spam detection logic.

features/groups/queries/group.query.ts (2)

97-105: Excellent comprehensive defensive coding in member addition logic!

The extensive use of optional chaining and nullish coalescing properly handles all potential undefined scenarios while maintaining the correct data structure updates.


123-133: Solid defensive coding in member removal logic!

The safe destructuring and array operations correctly handle cases where member data might be incomplete, ensuring robust group updates.

features/groups/mutations/remove-group-members-from-group.mutation.ts (2)

3-3: LGTM: Import added for explicit typing.

The IGroup import supports the explicit typing added below for better type safety.


47-59: Excellent defensive programming patterns.

The implementation correctly handles the optional members property with:

  • Explicit IGroup typing for updatedGroup
  • Nullish coalescing (??) to provide safe fallbacks for undefined members
  • Optional chaining (?.) for safe property access during deletion

These patterns align well with the updated IGroup interface making members optional.

features/groups/mutations/promote-group-member-to-super-admin.mutation.ts (3)

3-4: LGTM: Improved import organization.

Adding the IGroup import and organizing the invalidateGroupPermissionsQuery import enhances code clarity.


46-58: Consistent defensive programming implementation.

The mutation properly handles optional members property with:

  • Explicit IGroup typing
  • Comprehensive nullish coalescing for all nested property access
  • Safe fallback to empty objects/arrays

This maintains consistency with other group mutations in the PR.
