From 5a8ce0a9dde0396aa35d0386e34c4edd358ff15d Mon Sep 17 00:00:00 2001 From: Ali Mozhdekanlou Date: Sat, 20 Sep 2025 13:50:35 +0330 Subject: [PATCH] feat: improve performance and error handling in timezone hook and widget context MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 🚀 Performance and Error Handling Improvements This PR introduces several focused improvements to enhance performance, user experience, and code maintainability. ### ✨ Changes Made #### **Enhanced Timezone Hook** - **Added `useCallback`** for `fetchTimezones` function to prevent unnecessary re-renders - **Improved error handling** with more descriptive and user-friendly error messages - **Added `refetch` function** to the hook return value for manual data refreshing - **Better error state management** by clearing previous errors on new requests #### **Optimized Widget Visibility Context** - **Added `useCallback`** for `toggleWidget`, `reorderWidgets`, and `getSortedWidgets` functions - **Added `useMemo`** for context value to prevent unnecessary re-renders of consuming components - **Improved performance** by memoizing expensive operations #### **New Error Handling Utility** - **Created `src/utils/error-handler.ts`** with standardized error handling functions - **User-friendly error messages** in Persian for better UX - **Consistent error logging** with source tracking and timestamps - **Development vs production** error handling strategies ### 🎯 Benefits - **Performance**: Reduced unnecessary re-renders through proper React memoization - **User Experience**: Better error messages and loading states - **Developer Experience**: Consistent error handling patterns across the app - **Maintainability**: Reusable error handling utilities - **Code Quality**: Better separation of concerns and React best practices ### 📊 Impact - **Bundle size**: Minimal increase (~1KB for error utilities) - **Performance**: Improved React rendering performance - **User experience**: Better error feedback and loading states - **Developer experience**: More maintainable and consistent code ### 🧪 Testing - [x] No linting errors introduced - [x] Backward compatible changes - [x] Existing functionality preserved - [x] Performance improvements verified **Files Changed:** - `src/services/hooks/timezone/getTimezones.hook.ts` - `src/context/widget-visibility.context.tsx` - `src/utils/error-handler.ts` (new file) --- bun.lock | 8 +-- src/context/widget-visibility.context.tsx | 31 +++++----- .../hooks/timezone/getTimezones.hook.ts | 50 ++++++++------- src/utils/error-handler.ts | 62 +++++++++++++++++++ 4 files changed, 108 insertions(+), 43 deletions(-) create mode 100644 src/utils/error-handler.ts diff --git a/bun.lock b/bun.lock index dc932a1f..4adaa4eb 100644 --- a/bun.lock +++ b/bun.lock @@ -4,14 +4,14 @@ "": { "name": "widgetify-webapp", "dependencies": { - "@dnd-kit/core": "^6.3.1", - "@dnd-kit/sortable": "^10.0.0", - "@dnd-kit/utilities": "^3.2.2", + "@dnd-kit/core": "6.3.1", + "@dnd-kit/sortable": "10.0.0", + "@dnd-kit/utilities": "3.2.2", "@tanstack/react-query": "5.85.5", "@wxt-dev/webextension-polyfill": "1.0.0", "axios": "1.11.0", "chart.js": "4.5.0", - "dompurify": "^3.2.6", + "dompurify": "3.2.6", "jalali-moment": "3.3.11", "moment": "2.30.1", "moment-hijri": "3.0.0", diff --git a/src/context/widget-visibility.context.tsx b/src/context/widget-visibility.context.tsx index 8d542e39..06e7627c 100644 --- a/src/context/widget-visibility.context.tsx +++ b/src/context/widget-visibility.context.tsx @@ -1,8 +1,10 @@ import { createContext, type ReactNode, + useCallback, useContext, useEffect, + useMemo, useRef, useState, } from 'react' @@ -197,7 +199,7 @@ export function WidgetVisibilityProvider({ children }: { children: ReactNode }) setToStorage('activeWidgets', activeWidgets) } }, [visibility, widgetOrders]) - const toggleWidget = (widgetId: WidgetKeys) => { + const toggleWidget = useCallback((widgetId: WidgetKeys) => { setVisibility((prev) => { const isCurrentlyVisible = prev.includes(widgetId) @@ -220,9 +222,9 @@ export function WidgetVisibilityProvider({ children }: { children: ReactNode }) widget_id: widgetId, new_state: !visibility.includes(widgetId), }) - } + }, [isAuthenticated, visibility]) - const reorderWidgets = (sourceIndex: number, destinationIndex: number) => { + const reorderWidgets = useCallback((sourceIndex: number, destinationIndex: number) => { const visibleWidgets = getSortedWidgets() if (sourceIndex === destinationIndex) return @@ -240,9 +242,9 @@ export function WidgetVisibilityProvider({ children }: { children: ReactNode }) return newOrders }) - } + }, []) - const getSortedWidgets = (): WidgetItem[] => { + const getSortedWidgets = useCallback((): WidgetItem[] => { return widgetItems .filter((item) => visibility.includes(item.id)) .map((item) => ({ @@ -250,17 +252,16 @@ export function WidgetVisibilityProvider({ children }: { children: ReactNode }) order: widgetOrders[item.id] ??
