Prisma Connection Pool Exhausted - Cannot Connect to Database
API requests start failing with 'too many connections' or 'connect ECONNREFUSED' errors. The database was working fine but suddenly stops accepting connections.
This typically happens under load or after the app has been running for a while, and restarting the app temporarily fixes it.
Error Messages You Might See
PrismaClientInitializationError: Can't reach database server at `localhost`
Error: too many connections for role
Error: connect ECONNREFUSED 127.0.0.1:5432
Common Causes
- Prisma Client not being reused across requests - creating new instances continuously
- Database connection pool size too small for concurrent requests
- Connections not being closed properly after queries
- Long-running queries holding connections idle
- Pool timeout set too low, causing connection exhaustion
How to Fix It
Create a singleton Prisma Client instance: export const prisma = new PrismaClient(); // import in routes
Configure connection pool in DATABASE_URL: postgresql://user:pass@host/db?schema=public&connection_limit=5
Add proper error handling and disconnect: process.on('SIGINT', async () => { await prisma.$disconnect(); })
Real developers can help you.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

What's the best way to use Prisma in serverless?
Create a singleton pattern with module-level instantiation to reuse connections across cold starts
What's a safe connection pool size?
For WebContainer: 2-3. For production: 10-20. Adjust based on concurrent users and query patterns
How do I debug connection issues?
Enable Prisma debug logging: DEBUG=prisma:* npm run dev
