Overview

Implement a consistent toast notification system using sonner to provide immediate feedback for user actions across the application.

Context

MSP engineers need immediate confirmation that actions succeeded to reduce cognitive load and prevent errors. Currently, the app has inconsistent feedback patterns (button state changes, modal errors, page-level banners).

Design Document

See: docs/plans/2026-02-07-notification-system-design.md

Implementation Tasks

Phase 1: Core Infrastructure

  • Install sonner package
  • Create toast utility wrapper (lib/toast.ts)
  • Add Toaster provider to main.tsx
  • Sync theme store with Toaster component

Phase 2: Add Success Notifications

  • Tree operations (save, delete, publish)
  • Folder operations (create, edit, delete, add/remove trees)
  • Session export and clipboard copy
  • Settings and account updates

Phase 3: Error Standardization

  • Add global API error interceptor
  • Remove redundant error handling
  • Keep inline validation errors, replace page-level banners

Phase 4: Refinement

  • Verify consistent vocabulary
  • Test dark mode appearance
  • Run accessibility checks
  • Performance verification

Acceptance Criteria

  • All user-initiated actions show appropriate success/error toasts
  • Toast theme syncs with app theme (dark/light mode)
  • Screen readers announce toast messages
  • No accessibility violations in Lighthouse
  • Bundle size increase <15KB gzipped

Estimated Effort

1-2 days

Priority

Critical - Foundational infrastructure that improves UX across entire app
