Critical security vulnerabilities and missing production safeguards detected. SQL injection risk, exposed secrets, and no rate limiting make this unsafe for production deployment.
Summary
Significant performance bottlenecks detected. Missing database connection pooling will cause crashes under moderate load. N+1 queries in user dashboard will make page loads slow as the user base grows.
Issues Found (2)
No Database Connection Pooling
CRITICALlib/db/connection.ts:15
Description
The application creates a new database connection for every request without connection pooling. Under moderate load (100+ concurrent users), this will exhaust available connections and crash the application.
Business Impact
CRITICAL: App will crash during traffic spikes. Recovery requires manual restart, leading to downtime and lost revenue.
Recommendation
Implement connection pooling using Prisma with pool size 10-20 or pg-pool. Configure connection limits based on your database plan.
Safe Fix Guidelines
Update Prisma client instantiation to include connection_limit parameter. Test under load with artillery or k6.
N+1 Query Problem in Dashboard
HIGHapi/dashboard/projects.ts:28
Description
The user dashboard fetches a list of projects, then makes a separate database query for each project to get its stats. For a user with 50 projects, this results in 51 database queries.
Business Impact
HIGH: Dashboard page load times increase linearly with number of projects. Users with many projects will experience 5-10 second load times.
Recommendation
Use Prisma `include` or raw SQL with JOINs to fetch projects and their stats in a single query.
Safe Fix Guidelines
Replace the loop with a single query using Prisma.project.findMany({ include: { stats: true } })
