Silent Error Swallowing 
Tell me more
What is the issue?
Empty catch block silently swallows errors from AsyncStorage.getItem() without logging or providing context about the failure.
Why this matters
Silent error handling makes it difficult to diagnose issues when AsyncStorage operations fail unexpectedly in production.
Suggested change ∙ Feature Preview
Add error logging to provide context:
try {
const stored = await AsyncStorage.getItem(LAST_FETCH_PREFIX + queryKey);
return stored ? parseInt(stored, 10) : 0;
} catch (error) {
console.error(`Failed to get last fetch time for ${queryKey}:`, error);
return 0;

Unsafe Async Event Processing 
Tell me more
What is the issue?
The setTimeout with 0ms delay is used to process and update event data, which could lead to race conditions and inconsistent state updates.
Why this matters
Processing events asynchronously without proper coordination can result in missed updates or inconsistent data state when multiple events are being processed simultaneously.
Suggested change ∙ Feature Preview
Replace the setTimeout with a more reliable synchronous processing approach:
const processEvents = () => {
const kind1: string[] = [];
const kind6: string[] = [];
const kind7: string[] = [];
const kind16: string[] = [];
const kind9735: string[] = [];
socialEvents.forEach((event) => {
queryClient.setQueryData(nostrQueryKeys.event(event.id), event);
switch (event.kind) {
case 1: kind1.push(event.id); break;
case 6: kind6.push(event.id); break;
case 7: kind7.push(event.id); break;
case 16: kind16.push(event.id); break;
case 9735: kind9735.push(event.id); break;
}
});
// Batch update queries
queryClient.setQueriesData({
queries: [
{ queryKey: nostrQueryKeys.comments(pubkey), updater: (old: string[] = []) => [...kind1, ...old] },
{ queryKey: nostrQueryKeys.reposts(pubkey), updater: (old: string[] = []) => [...kind6, ...old] },
{ queryKey: nostrQueryKeys.reactions(pubkey), updater: (old: string[] = []) => [...kind7, ...old] },
{ queryKey: nostrQueryKeys.genericReposts(pubkey), updater: (old: string[] = []) => [...kind16, ...old] },
{ queryKey: nostrQueryKeys.zapReceipts(pubkey), updater: (old: string[] = []) => [...kind9735, ...old] }
]
});
};

Inflexible Timestamp Setting
Tell me more
What is the issue?
The setLastFetchTime function is called with just a queryKey parameter but doesn't allow setting a custom timestamp, which could lead to race conditions in certain scenarios.
Why this matters
If multiple operations need to be synchronized or if we need to record a specific event's timestamp, the current implementation forces the use of the current time, potentially creating inconsistencies in the event timeline.
Suggested change ∙ Feature Preview
Modify the function to accept an optional timestamp parameter:
export const setLastFetchTime = async (
queryKey: string,
timestamp?: number
): Promise<void> => {
const now = timestamp ?? Math.floor(Date.now() / 1000);
await AsyncStorage.setItem(LAST_FETCH_PREFIX + queryKey, now.toString());

Silent JSON Parse Error in Profile Metadata
Tell me more
What is the issue?
The decodeProfileMetadata function catches JSON parse errors silently without logging or providing context about the failure.
Why this matters
Silently returning null on parse errors makes debugging profile metadata issues difficult and could mask underlying data corruption problems.
Suggested change ∙ Feature Preview
Add error logging and context to the catch block:
catch (error) {
console.error(`Failed to parse profile metadata: ${error.message}`, { eventId: event.id });
return null;

Description by Korbit AI
What change is being made?
Add a
NostrEventProviderto the application to manage Nostr events globally, refactor components to utilize the new provider for event data, and update caching strategies for improved performance and integration.Why are these changes being made?
This change improves the scalability and maintainability of the codebase by centralizing Nostr event logic, reducing redundant API calls through caching, and streamlining the integration process of Nostr events across the application. By leveraging context and the
NostrEventProvider, various components can now seamlessly access event data, leading to better data consistency and performance optimization. Furthermore, this refactor supports future expansions in functionality and provides a clearer structure for managing event types within the app.
