Multi-Tenant (Prisma)

Database-per-tenant multi-tenancy with Prisma ORM. Each tenant gets a separate PrismaClient with its own datasourceUrl.

Features

• TenantAdapter with subdomain resolution
• TenantConnectionManager<PrismaClient> — typed connection cache
• TenantDbService — injectable wrapper using getCurrentTenant()
• AuthAdapter with JWT authentication
• Provider/tenant pattern with fallback to default database
• Each getDb() call returns a fully typed PrismaClient
