Local development (Docker):

API

Environment Variables

The API requires the following environment variables:

Redis Configuration

# Local development (Docker):
REDIS_URL=redis://localhost:6379
REDIS_QUEUE_URL=redis://localhost:6379

# Production:
# REDIS_URL=rediss://:[email protected]:6379 (Upstash - multi-region cache)
# REDIS_QUEUE_URL=redis://...railway.internal:6379 (Railway Redis - queue)

Local Development Setup

1. Start Redis with Docker:

   bashCopy

   docker run -d --name redis -p 6379:6379 redis:alpine
   

2. Set environment variable:

   bashCopy

   export REDIS_URL=redis://localhost:6379
   

Database Configuration

DATABASE_PRIMARY_URL=postgresql://...
DATABASE_FRA_URL=postgresql://...  # EU replica
DATABASE_IAD_URL=postgresql://...  # US East replica
DATABASE_SJC_URL=postgresql://...  # US West replica

Development

bun dev

Production

bun start

Cache Implementation

The API uses Redis for distributed caching across multiple server instances:

• apiKeyCache: Caches API key lookups (30 min TTL)
• userCache: Caches user data (30 min TTL)
• teamCache: Caches team access permissions (30 min TTL)
• teamPermissionsCache: Caches team permission lookups (30 min TTL)
• replicationCache: Tracks recent mutations for read-after-write consistency (10 sec TTL)

Environment-Specific Configuration

The Redis client automatically configures itself based on the environment:

Production (Railway):

• Standard IPv4 connections
• Longer connection timeouts (10s)
• TLS support for Upstash Redis (cache)
• Railway internal networking for queue Redis

Development (Local):

• IPv4 connections
• Shorter timeouts (5s)
• No TLS

This ensures cache consistency across multiple stateful servers and eliminates the "No procedure found" TRPC errors caused by cache misses.
