Summary

Implements tier-based vehicle limits to prevent users from exceeding their subscription allowance:

  • Free tier: 2 vehicles maximum
  • Pro tier: 5 vehicles maximum
  • Enterprise tier: Unlimited vehicles

Fixes #23

Implementation Details

Backend Changes

  • Added VEHICLE_LIMITS configuration to feature-tiers.ts with per-tier limits
  • Implemented getVehicleLimit() and canAddVehicle() helper functions
  • Added transaction-based limit enforcement with FOR UPDATE locking to prevent race conditions
  • Created VehicleLimitExceededError class for limit violations
  • Added countByUserId() method to VehiclesRepository
  • Returns 403 with TIER_REQUIRED error format (consistent with existing tier gating)
  • Comprehensive test coverage for all limit logic

Frontend Changes

  • Extended useTierAccess hook with getResourceLimit() and isAtResourceLimit() methods
  • Created VehicleLimitDialog component with mobile/desktop responsive modes
  • Added useVehicleLimitCheck shared hook for managing limit state
  • Updated VehiclesPage (desktop) with limit checks and lock icon when at limit
  • Updated VehiclesMobileScreen with same limit behavior
  • Both mobile and desktop show dialog instead of form when limit reached

Race Condition Prevention

The implementation uses PostgreSQL transactions with FOR UPDATE locking:

BEGIN;
SELECT COUNT(*) FROM vehicles WHERE user_id = $1 FOR UPDATE;
-- Check limit
INSERT INTO vehicles (...);
COMMIT;

This ensures concurrent requests cannot bypass the limit.

Test Plan

  • Unit tests pass for feature-tiers helpers
  • Unit tests pass for VehiclesRepository.countByUserId
  • Integration tests for all tier limits (free, pro, enterprise)
  • TypeScript compilation clean
  • VehicleLimitDialog tests pass
  • Manual testing on desktop (1920px)
  • Manual testing on tablet (768px)
  • Manual testing on mobile (320px)

Screenshots

Manual testing screenshots to be added

Notes

  • Integration tests require user_profiles table which may not exist in all test databases
  • Dialog uses "Upgrade (Coming Soon)" button - Stripe integration to be added later
  • Error format aligned with existing TIER_REQUIRED pattern for consistency

PostgreSQL error 0A000 (feature_not_supported) occurs when using
FOR UPDATE with aggregate functions like COUNT(*). Row-level locking
requires actual rows to lock.

Changes:
- Select id column instead of COUNT(*) aggregate
- Count rows in application using .length
- Maintains transaction isolation and race condition prevention
