From 14c5c148b93944a5ff9e5460939470faa6241e76 Mon Sep 17 00:00:00 2001 From: chamikaJ Date: Mon, 30 Jun 2025 11:02:41 +0530 Subject: [PATCH] refactor(task-management): optimize task management components with performance enhancements - Updated import statements for consistency and clarity. - Refined task sorting and update logic to improve responsiveness. - Enhanced error logging for better debugging during task sort order changes. - Increased overscan count in virtualized task lists for smoother scrolling experience. - Introduced lazy loading for heavy components to reduce initial load times. - Improved CSS styles for better responsiveness and user interaction across task management components. --- .../commands/on-task-sort-order-change.ts | 14 +- worklenz-backend/src/socket.io/index.ts | 2 +- .../enhanced-kanban/VirtualizedTaskList.tsx | 6 +- .../task-management/asana-style-lazy-demo.tsx | 265 +++++++++ .../assignee-dropdown-content.tsx | 270 +++++++++ .../task-management/improved-task-filters.tsx | 43 +- .../lazy-assignee-selector.tsx | 81 +++ .../task-management/lazy-date-picker.tsx | 101 ++++ .../components/task-management/task-group.tsx | 27 + .../task-management/task-list-board.tsx | 524 ++++++++++++------ .../task-management/task-row-utils.ts | 2 +- .../components/task-management/task-row.tsx | 511 ++++++++++++++--- .../virtualized-task-group.tsx | 2 +- .../task-management/virtualized-task-list.tsx | 131 +++-- .../projects/projectView/project-view.css | 22 +- .../src/styles/task-management.css | 10 +- 16 files changed, 1685 insertions(+), 326 deletions(-) create mode 100644 worklenz-frontend/src/components/task-management/asana-style-lazy-demo.tsx create mode 100644 worklenz-frontend/src/components/task-management/assignee-dropdown-content.tsx create mode 100644 worklenz-frontend/src/components/task-management/lazy-assignee-selector.tsx create mode 100644 worklenz-frontend/src/components/task-management/lazy-date-picker.tsx diff --git a/worklenz-backend/src/socket.io/commands/on-task-sort-order-change.ts b/worklenz-backend/src/socket.io/commands/on-task-sort-order-change.ts index 94b327c3..450551fb 100644 --- a/worklenz-backend/src/socket.io/commands/on-task-sort-order-change.ts +++ b/worklenz-backend/src/socket.io/commands/on-task-sort-order-change.ts @@ -118,7 +118,7 @@ const onTaskSortOrderChange = async (io: Server, socket: Socket, data: ChangeReq project_id, team_id, user_id: userId, - update_type: 'task_sort_order_change', + update_type: "task_sort_order_change", task_id: task.id, from_group, to_group, @@ -126,7 +126,7 @@ const onTaskSortOrderChange = async (io: Server, socket: Socket, data: ChangeReq };

+ Performance Benefits: +
    +
  • ✅ Faster Initial Load: Only lightweight placeholders load initially
    • +
  • ✅ Reduced Bundle Size: Heavy components split into separate chunks
    • +
  • ✅ Better UX: Instant visual feedback, components load on demand
    • +
  • ✅ Memory Efficient: Components only consume memory when needed
    • +
  • ✅ Network Optimized: Parallel loading of components as user interacts
    • +

}> + + + )} + + {showComponents.labels && ( + Loading labels selector...}> + + + )} + + + + + +
+ How it works: +
    +
  1. 1. Page loads instantly with lightweight placeholder buttons
    2. +
  2. 2. User clicks a button to interact with a feature
    3. +
  3. 3. Heavy component starts loading in the background
    4. +
  4. 4. Loading state shows immediate feedback
    5. +
  5. 5. Full component renders when ready
    6. +
  6. 6. Subsequent interactions are instant (component cached)
