Recent entries

1.1.0

2026-03-19

Lite mode local-only workflow for event setup and dispatch, including browser-local persistence without Firebase sync.

Added

  • • Lite mode local-only workflow for event setup and dispatch, including browser-local persistence without Firebase sync.
  • • Lite dispatch navbar controls for Posting Schedule, Clear Event, and Export Summary actions.

Changed

  • • Unified Lite and Cloud dispatch onto a shared dispatch UI flow to reduce duplication and keep feature parity.
  • • Lite dispatch navbar behavior now mirrors main app navbar behavior (clock placement, auth controls, desktop/mobile parity).
  • • Lite dispatch route now uses a lightweight wrapper that delegates to the shared dispatch page.

Fixed

  • • Resolved Next.js route export/type issues on dispatch pages that could fail production builds.
  • • Cleared lint/type build blockers across dispatch, venue management, profile, and modal components.
  • • Updated venue map icon rendering to satisfy Next.js image lint requirements.
  • • Suppressed non-actionable React hydration mismatch warnings in development when browser extensions inject attributes on root HTML/body before client hydration.

1.0.0

2026-02-28

Initial public release of CrowdCAD — an open-source, browser-based Computer-Aided Dispatch system for volunteer EMS and event medical teams.

Notes

  • • Next.js 15 App Router frontend with TypeScript, TailwindCSS, and HeroUI component library.
  • • Firebase backend: Email/password authentication, Firestore real-time database, Firebase Hosting deployment pipeline.
  • • Firebase Data Connect schema (Cloud SQL / PostgreSQL) for structured event, unit, and incident data.
  • • Dark-mode design system with a custom token palette (surface, accent, status.) applied globally via Tailwind.
  • • Create and configure events with name, date, venue, and posting schedule.
  • • Per-event posting schedules: define time slots, assign teams to posts, and edit times inline.
  • • Scheduled auto-post sync: at each posting-time boundary the system automatically prepares teams to be moved to their assigned posts.
  • • Event summary page with activity charts (SummaryCharts).
  • • Share modal to grant other authenticated users access to an event.
  • • End-event modal with summary navigation.
  • • Create and edit venues with metadata (equipment capacity, medical post definitions).
  • • Image-based interactive venue maps with named layers; markers for teams and equipment are customizable.
  • • Equipment staging locations attached to posts.
  • • Call tracking table — live call log with columns for call number, chief complaint, age/sex, location, status, and assigned teams.
  • • Clinic tracking — separate table for walk-up patients with walkup-entry modal.
  • • Quick-call entry form for rapid incident creation.
  • • Priority call flagging (visual highlight and sort).
  • • Duplicate call detection and resolution workflow.
  • • Cell-level inline editing for call fields with click-to-edit UX.
  • • Per-call team assignment with status tracking and log entries.
  • • Resolved-call archive toggle (show/hide resolved rows).
  • • Add, edit, and delete field teams with named members and certification levels (CPR, EMT-B, EMT-A, EMT-P, RN, MD/DO); lead designation per member.
  • • Add, edit, and delete supervisors with call sign and certification.
  • • Team status and location controls; per-team status timer derived from activity log.
  • • Sort teams by availability, name (A→Z / Z→A).
  • • Condensed team card view mode for high team-count events.
  • • Equipment cards with status (Available / Deployed / In Use / Maintenance), current location, and staging location.
  • • Add venue-defined equipment to the dispatch board.
  • • Inline location editing with commit-on-blur.
  • • Equipment reset-to-staging-location bulk action.
  • • Soft-delete equipment from active board.
  • • .env.example with all required Firebase and SMTP environment variables documented.
  • • firebase.json.template for self-hosted Firebase Hosting setup.
  • • firestore.rules with baseline security rules.
  • • scripts/backfillOrgIds.js migration helper.
  • • Full documentation suite: ARCHITECTURE.md, COMPONENTS.md, DEPLOYMENT.md, FIREBASESETUP.md, USERGUIDE.md.
  • • CONTRIBUTING.md, CODEOFCONDUCT.md, SECURITY.md, LICENSE.md (AGPL-3.0).

Unreleased

Foundation refactor: extracted core utilities to src/lib/ for reuse across features:

Added

  • • Foundation refactor: extracted core utilities to src/lib/ for reuse across features:
  • • uploadUtils.ts — file upload with exponential backoff retry logic (transient error detection, original error preservation).
  • • zoomPanUtils.ts — viewport math utilities (clampScale, clampPanPosition) for consistent zoom/pan behavior.
  • • markerUtils.ts — marker detection and placement helpers.
  • • Shared React hooks extracted to src/hooks/ for reuse:
  • • useZoomPan — manages zoom/pan state and mouse/wheel event handlers for map-based interfaces.
  • • useScheduleGeneration — generates shift schedules from event duration and team coverage.
  • • useTeamForm — team/supervisor form submission and validation.
  • • Shared UI primitives added to src/components/ui/:
  • • map-zoom-controls.tsx — zoom in/out/reset button cluster with accessibility labels (reused across event create and venue management).
  • • map-pan-surface.tsx — reusable pan/wheel interaction surface for canvas-based viewers.
  • • Event creation flow decomposed into focused section components under src/components/event-create/:
  • • MetadataSection.tsx — event name, date, and venue selection.
  • • TeamStaffingSection.tsx — team roster assignment.
  • • SupervisorStaffingSection.tsx — supervisor roster assignment.
  • • PostingScheduleSection.tsx — shift schedule generation and management.
  • • PostsEquipmentSection.tsx — posts and equipment selection with multi-select state.
  • • Venue management flow decomposed into focused section components under src/components/venue-management/:
  • • EquipmentManagementSection.tsx — add/edit/delete equipment with stable React keys.
  • • LayerControlBar.tsx — layer navigation (previous/next/add/delete) with accessibility labels.
  • • MarkerModeToggleButton.tsx — toggle marker placement mode.
  • • PendingMarkerDialog.tsx — marker naming dialog.
  • • MarkerPlacementInstruction.tsx — on-screen guidance during marker placement.
  • • Lite event drafts now persist a postingScheduleEnabled flag to keep posting schedule behavior consistent between setup and dispatch.

Changed

  • • Event creation page (src/app/(main)/events/[eventId]/create/page.tsx) now uses decomposed section components instead of a monolithic page layout, improving maintainability and testability.
  • • Venue management page (src/app/(main)/venues/management/page.client.tsx) now uses decomposed section components and shared map controls instead of page-local implementations.
  • • Dispatch call tracking page now threads styling through rowClassName prop to restore per-status visual differentiation.
  • • Pan math in zoomPanUtils.clampPanPosition corrected to properly clamp against scaled image overflow (fixes off-by-factor error at different zoom levels).
  • • Lite setup Locations/Equipment add row now uses an attached input + action button style with aligned corner radii and consistent spacing.
  • • Teams and Supervisors panel actions in Lite setup now use explicit Add Team and Add Supervisor buttons.
  • • Lite dispatch navbar now hides Posting Schedule when posting schedule is disabled in event setup.
  • • Lite navbar primary links were simplified to focus on Lite routes (Lite Home, Create).
  • • Landing page copy and CTA text were refined (CrowdCAD Lite footer label and Lite subtitle wording), and Lite CTA iconography was simplified.
  • • Updated public/logo.svg artwork/viewBox for refined logo rendering.

Fixed

  • • Upload retry logic now only retries on transient Firebase Storage errors (storage/retry-limit-exceeded, storage/unknown) to avoid masking real failures, and preserves original error for diagnostics.
  • • Removed initial navbar mount flicker/layout shift on page reload by rendering the main app navbar in the initial render path instead of client-only lazy loading.
  • • Equipment list now uses stable React keys (item.id) instead of array indices to prevent component state loss on edit/delete operations.
