⏭️ Phase 7 Next Steps

Updated: November 7, 2025 3:00 PM
Priority: Start with Backend Foundation

🔥 Immediate Actions (Start Now)

1. Create Backend Data Controller 🔴 CRITICAL

File: apis/backend-api/src/app/data/data.controller.ts
Time: 2 hours
Priority: CRITICAL

Why Critical: Without backend APIs, none of the frontend services can function

Steps:

1. Create data/ folder in backend-api/src/app
2. Create data.controller.ts with NestJS controller
3. Implement POST /query endpoint first
4. Test with Postman or Thunder Client
5. Verify returns data from MongoDB

Success: Can query universe collections via API

2. Implement Data Service 🔴 CRITICAL

File: apis/backend-api/src/app/data/data.service.ts
Time: 1 hour
Priority: CRITICAL

Steps:

1. Create data.service.ts
2. Inject Connection from @nestjs/mongoose
3. Implement query business logic
4. Add validation
5. Add logging

Success: Service handles all data operations safely

3. Create Data Module 🟡 HIGH

File: apis/backend-api/src/app/data/data.module.ts
Time: 30 minutes
Priority: HIGH

Steps:

1. Create data.module.ts
2. Import SpacesModule (for SpaceDatabaseService)
3. Provide UniverseDataController
4. Provide UniverseDataService
5. Export service

Success: Module configured correctly

4. Integrate Data Module 🟡 HIGH

File: apis/backend-api/src/app/app.module.ts
Time: 15 minutes
Priority: HIGH

Steps:

1. Import DataModule
2. Add to imports array
3. Restart backend server
4. Test /api/spaces/.../data/collections endpoint

Success: Backend starts without errors, endpoints accessible

5. Test Backend APIs 🟡 HIGH

Tool: Postman or Thunder Client
Time: 1 hour
Priority: HIGH

Test Cases:

1. GET /api/spaces/{spaceId}/universes/{universeId}/collections

   • Should return empty array (no collections yet)

2. POST /api/spaces/{spaceId}/universes/{universeId}/data/users/query

   • Should return empty or error (collection might not exist)

3. POST /api/spaces/{spaceId}/universes/{universeId}/data/users/insert

   • Should insert record
   • Verify in MongoDB Compass

4. Test update, delete, export endpoints

Success: All endpoints respond correctly

📅 This Week's Goals

Monday-Tuesday (Day 1-2)

Focus: Backend Data APIs

Deliverables:

• UniverseDataController complete
• UniverseDataService complete
• DataModule configured
• All CRUD endpoints working
• Tested with Postman

Hours: 8 hours

Wednesday (Day 3)

Focus: Universe Collection Triggers

Deliverables:

• Hook added to universe creation
• SpaceDatabaseService.createUniverseCollections() called
• Tested universe creation
• Verified collections in MongoDB

Hours: 4 hours

Thursday-Friday (Day 4-5)

Focus: Database Management Blocks

Deliverables:

• database-management-blocks.ts created
• All 5 block templates defined
• Execution handlers implemented
• Blocks appear in Singularity library
• Each block tested individually

Hours: 8 hours

🎯 Week 1 End State

By end of Week 1, we should have:

• ✅ Complete backend API for data operations
• ✅ Universe collections auto-create on creation
• ✅ Database blocks functional in Singularity
• ✅ All pieces tested individually

Result: Foundation complete for Week 2 integration work

📋 Quick Start Checklist

Before You Start:

• Backend running: cd apis/backend-api && npm run start:dev
• MongoDB accessible
• Postman/Thunder Client ready
• Have test space ID and universe ID

Create Files In Order:

1. apis/backend-api/src/app/data/data.controller.ts
2. apis/backend-api/src/app/data/data.service.ts
3. apis/backend-api/src/app/data/data.module.ts
4. Update apis/backend-api/src/app/app.module.ts
5. Test endpoints
6. Update apis/backend-api/src/app/spaces/spaces.service.ts (universe trigger)
7. Create libs/singularity-lib/src/lib/templates/database-management-blocks.ts
8. Add execution handlers to logic-execution-engine.service.ts

Test Each Step:

• Controller compiles
• Endpoints respond
• Data persists to MongoDB
• Blocks appear in library
• Blocks execute correctly

💡 Pro Tips

For Backend Development:

1. Start simple - Get one endpoint working first
2. Test immediately - Don't write all endpoints before testing
3. Use MongoDB Compass - Verify data is actually in database
4. Log everything - Use NestJS Logger for debugging
5. Handle errors - Wrap in try/catch, return meaningful errors

For Database Blocks:

1. Copy existing blocks - Use HTTP or Auth blocks as templates
2. Test in isolation - Create flow with just the database block
3. Check console - Verify execution logs
4. Inspect variables - Use Variables tab to see results
5. Iterate quickly - Fix, test, repeat

For Integration:

1. One feature at a time - Don't integrate everything at once
2. Verify each connection - Backend → Frontend → UI
3. Real data always - No mocks in integration testing
4. Perfect isolation - Verify space A can't see space B data

🚨 Critical Success Factors

Must Get Right:

1. Universe Scoping - Every query must filter by universeId
2. Authentication - All endpoints must verify ownership
3. Data Isolation - Perfect multi-tenancy
4. Error Handling - Graceful failures
5. Performance - Fast queries with proper indexes

Can Iterate Later:

1. Advanced analytics
2. Real-time updates
3. Bulk operations UI
4. Query builder complexity
5. Export formats
