Implementation Checklist - Simplified Architecture

✅ Completed

Phase 1: Foundation Setup

  • Redis account created (Upstash)
  • Environment variables configured
  • Created Redis client (client.ts)
  • Created RateLimiter (rateLimiter.ts)
  • Created IdempotencyGuard (idempotency.ts)
  • Created NonceStore (nonces.ts)
  • Created middleware (rateLimit.ts, validation.ts)
  • Created validation schemas (event, task, user)
  • Updated shared types (removed event_type, added reward_types)

📋 Next Steps

Step 1: Install Dependencies & Test (5 minutes)

npm install @upstash/redis zod
npm run dev

Test Redis connection in browser console or add to hooks.server.ts:

import { testRedisConnection } from '$lib/infrastructure/redis/client';
await testRedisConnection(); // Should log "✅ Redis connected"

Step 2: Update First Endpoint - Predictions (20 minutes)

File: src/routes/api/predictions/+server.ts

Apply the pattern:

  1. Add rate limiting
  2. Add validation
  3. Clean up logic

Status: Ready to implement ⬇️

Step 3: Update Verification Endpoints (2-3 hours)

  • src/routes/api/tasks/verify-twitter/+server.ts

    • Add rate limiting
    • Add idempotency guard
    • Add validation

  • src/routes/api/tasks/verify-discord/+server.ts

    • Same pattern

  • src/routes/api/tasks/verify-telegram/+server.ts

    • Same pattern

Step 4: Update Task Submissions (1 hour)

  • src/routes/api/tasks/submit/+server.ts (if exists)
    • Add idempotency
    • Add validation

Step 5: Update Wallet Auth (1 hour)

  • Create src/routes/api/auth/wallet/nonce/+server.ts

    • Use NonceStore

  • Create src/routes/api/auth/wallet/verify/+server.ts

    • Use NonceStore
    • Verify signature
    • Rate limit

Step 6: Update Event Creation (30 minutes)

  • src/routes/api/events/+server.ts
    • Add rate limiting (5/hour)
    • Add validation with new schema
    • Update to use reward_types instead of rewards

Step 7: Critical Bug Fix (30 minutes)

  • Fix duplicate task registry
    • Consolidate src/lib/tasks/index.ts and src/lib/tasks/taskRegistry.ts
    • Update all imports

🎯 Success Criteria

After completion:

  • All endpoints have rate limiting
  • All inputs validated with Zod
  • Can't submit invalid data (get 422 error)
  • Can't spam requests (get 429 error)
  • Can't submit duplicates (get 409 error)
  • Wallet auth uses Redis nonces
  • No TypeScript errors
  • Application works as before (no regressions)

📊 Progress Tracking

Week 1 Goals:

  • Setup (Day 1)
  • First endpoint (Day 1-2)
  • Verification endpoints (Day 3-4)
  • Test everything (Day 5)

Week 2 Goals:

  • Task submissions
  • Wallet auth
  • Event creation
  • Final testing

🔍 Testing Checklist

For each updated endpoint, test:

  1. Valid request → Should work ✓
  2. Invalid data → Should get validation error (422)
  3. Rapid requests → Should get rate limited (429)
  4. Duplicate submission → Should get conflict (409)
  5. No auth → Should get unauthorized (401)

📝 Notes

Remember:

  • Redis is for DEFENSE, not caching (yet)
  • Supabase is your source of truth
  • Add caching only in Phase 4+ if needed
  • Test after each endpoint update

If stuck:

  • Check EXAMPLES_BEFORE_AFTER.md
  • Check SIMPLIFIED_ARCHITECTURE.md
  • Existing lints in Svelte files are pre-existing (not urgent)

Current Status: Foundation complete, ready for endpoint migration 🚀
