HRIStudio Implementation - Work in Progress

Current Status: Type Safety Issues Blocking Build

Date: December 2024
Task: Complete HRIStudio backend API implementation
Blocker: TypeScript compilation errors preventing production build

🚨 Immediate Issue

Build fails due to type safety violations in API routers:

Failed to compile.
./src/server/api/routers/admin.ts:29:9
Type error: No overload matches this call.

📊 Error Analysis Summary

From bun lint analysis:

• 54 unsafe any calls - Database operations not properly typed
• 48 unsafe error assignments - Missing proper error handling types
• 31 unsafe any assignments - Database queries returning any
• 25 explicit any types - Function parameters using any

🔍 Root Cause

Primary Issue: Using any type for database context instead of proper Drizzle types

// Current problematic pattern:
async function checkTrialAccess(
  db: any, // ← This should be properly typed
  userId: string,
  trialId: string
) { ... }

Secondary Issues:

1. Enum value mismatches (e.g., "admin" vs "administrator")
2. Schema field name mismatches (e.g., startTime vs startedAt)
3. Missing proper imports for database types

🎯 Current Task: Full Type Fixes

Approach: Fix types properly rather than workarounds

1. ✅ Fixed enum mismatches in admin router ("admin" → "administrator")
2. ✅ Fixed trial status enum ("running" → "in_progress")
3. ✅ Fixed audit logs field names ("details" → "changes")
4. 🚧 IN PROGRESS: Replace all db: any with proper Drizzle types
5. ⏳ NEXT: Fix schema field mismatches across all routers
6. ⏳ NEXT: Add proper error handling types

📝 Implementation Progress

✅ Completed (95% Backend)

• Database Schema: 31 tables, all relationships configured
• API Routers: 11 routers implemented (auth, users, studies, experiments, participants, trials, robots, media, analytics, collaboration, admin)
• Project Infrastructure: T3 stack properly configured

🚧 Current Work: Type Safety

Files being fixed:

• src/server/api/routers/admin.ts ✅ Enum fixes applied
• src/server/api/routers/trials.ts ⏳ Needs schema field alignment
• src/server/api/routers/robots.ts ⏳ Needs schema field alignment
• src/server/api/routers/analytics.ts ⏳ Needs type fixes
• src/server/api/routers/collaboration.ts ⏳ Needs type fixes
• src/server/api/routers/media.ts ⏳ Needs type fixes

❌ Removed from Scope (Per User Request)

• Unit testing setup - removed to focus on type fixes
• Vitest configuration - removed
• Test files - removed

🔧 Type Fix Strategy

Step 1: Database Context Typing

Replace all instances of:

// From:
async function helper(db: any, ...)

// To:
import { db as dbType } from "~/server/db"
async function helper(db: typeof dbType, ...)

Step 2: Schema Field Alignment

Known Mismatches to Fix:

• Trials: startTime/endTime → startedAt/completedAt
• Participants: identifier → participantCode
• Robots: Missing fields in schema vs router expectations
• Audit Logs: details → changes ✅ Fixed

Step 3: Enum Type Safety

Fixed:

• System roles: "admin" → "administrator" ✅
• Trial status: "running" → "in_progress" ✅

Still to verify:

• Study member roles enum usage
• Communication protocol enums
• Trust level enums

🎯 Success Criteria

• Build completes without type errors
• All API endpoints properly typed
• Database operations type-safe
• No any types in production code

📋 Next Actions

1. Systematically fix each router file
2. Import proper database types
3. Align schema field references
4. Test build after each file
5. Document any schema changes needed

⚠️ Notes

• No unit tests for now - focus on type safety first
• No workarounds - proper type fixes only
• Schema alignment may require database migrations
• Production build must pass before moving to frontend
