From 21206e8267b07b3bdaba0a3300edfdcaa252a697 Mon Sep 17 00:00:00 2001 From: Timothy2025-20 Date: Wed, 19 Aug 2026 22:10:18 +0100 Subject: [PATCH] perf: split useProofSubmit into usePendingProofs and useProofSubmit - Create usePendingProofs for HomeScreen (lightweight, only queue count and sync) - Keep useProofSubmit for SubmitProofScreen (full submission flow) - Both hooks share the same proofQueue module - No behavioral change - proof submission, queuing, and sync work identically - Add tests for both hooks independently - HomeScreen renders fewer state updates when proof state changes Closes #56 --- src/__tests__/hooks/usePendingProofs.test.ts | 80 ++++ src/__tests__/hooks/useProofSubmit.test.ts | 115 +++++ src/hooks/proofQueue.ts | 120 ++++++ src/hooks/usePendingProofs.ts | 79 ++++ src/hooks/useProofSubmit.ts | 243 ++++------- src/screens/HomeScreen.tsx | 360 +++------------- src/screens/SubmitProofScreen.tsx | 425 ++++--------------- 7 files changed, 601 insertions(+), 821 deletions(-) create mode 100644 src/__tests__/hooks/usePendingProofs.test.ts create mode 100644 src/__tests__/hooks/useProofSubmit.test.ts create mode 100644 src/hooks/proofQueue.ts create mode 100644 src/hooks/usePendingProofs.ts diff --git a/src/__tests__/hooks/usePendingProofs.test.ts b/src/__tests__/hooks/usePendingProofs.test.ts new file mode 100644 index 0000000..0fc23ed --- /dev/null +++ b/src/__tests__/hooks/usePendingProofs.test.ts @@ -0,0 +1,80 @@ +import { renderHook, act } from '@testing-library/react-hooks';
