Commands

pnpm nx run infra-db:db:generate   # Generate migration
pnpm nx run infra-db:db:migrate    # Run migrations
pnpm nx run infra-db:db:studio     # Drizzle Studio
pnpm nx run infra-db:db:push       # Push schema (dev)
pnpm nx run infra-db:db:seed       # Seed data
pnpm nx run infra-db:db:drop       # Drop tables (DANGER)

Schema Change Workflow

# 1. Modify schema in libs/infra/db/src/schema/
# 2. Generate migration
pnpm nx run infra-db:db:generate
# 3. Review migration in libs/infra/db/src/migrations/
# 4. Apply migration
pnpm nx run infra-db:db:migrate

Schema Conventions

import { pgTable, text, bigint, uuid, jsonb } from 'drizzle-orm/pg-core';
import { uuidv7 } from 'uuidv7';

export const users = pgTable('users', {
  // UUIDv7 primary key
  id: uuid('id')
    .primaryKey()
    .$defaultFn(() => uuidv7()),

  // BIGINT epoch timestamps
  createdAt: bigint('created_at', { mode: 'number' })
    .notNull()
    .$defaultFn(() => Date.now()),

  // JSONB for metadata
  metadata: jsonb('metadata').$type<Record<string, unknown>>(),

  // Realm for multi-tenancy
  realmId: uuid('realm_id').references(() => realms.id),
});

Key Patterns

• UUIDv7: Time-ordered primary keys
• BIGINT epoch: Timestamps as milliseconds
• JSONB: Flexible metadata
• Realm-based: Multi-tenancy support
