@revealui/db

Database schemas and Drizzle ORM integration for RevealUI.

Test Coverage: ~60% (best coverage in project, but still needs improvement)

Features

• Drizzle ORM: Type-safe database queries with Drizzle
• Schema Management: Database schema definitions for all RevealUI tables
• Multiple Providers: Works with Neon, Supabase, and Vercel Postgres
• Type Generation: Auto-generate TypeScript types from database schema
• Migrations: Database migration management with Drizzle Kit
• Type-safe: Full TypeScript support with inferred types

Installation

pnpm add @revealui/db

Usage

Import Database Client

import { createClient } from '@revealui/db/client'

const db = createClient({
  connectionString: process.env.POSTGRES_URL!
})

Import Schemas

// Import all schemas
import * as schema from '@revealui/db/schema'

// Import specific schemas
import { users } from '@revealui/db/schema/users'
import { posts } from '@revealui/db/schema/cms'
import { agentContexts } from '@revealui/db/schema/agents'
import { vectorMemory } from '@revealui/db/schema/vector'

Query Database

import { createClient } from '@revealui/db/client'
import { users } from '@revealui/db/schema/users'
import { eq } from 'drizzle-orm'

const db = createClient({ connectionString: process.env.POSTGRES_URL! })

// Query users
const allUsers = await db.select().from(users)

// Query with filter
const user = await db.select().from(users).where(eq(users.email, 'user@example.com'))

// Insert user
await db.insert(users).values({
  email: 'newuser@example.com',
  name: 'New User'
})

Database Management

# Generate types from schema
pnpm --filter @revealui/db generate:types

# Generate migration files
pnpm --filter @revealui/db db:generate

# Run migrations
pnpm --filter @revealui/db db:migrate

# Push schema changes (development only)
pnpm --filter @revealui/db db:push

# Open Drizzle Studio (database GUI)
pnpm --filter @revealui/db db:studio

Type Safety

All database operations are fully type-safe:

import { createClient } from '@revealui/db/client'
import { users } from '@revealui/db/schema/users'

const db = createClient({ connectionString: process.env.POSTGRES_URL! })

// TypeScript knows the shape of user rows
const allUsers = await db.select().from(users)
// allUsers: { id: string, email: string, name: string | null, ... }[]

// Insert is type-checked
await db.insert(users).values({
  email: 'test@example.com',
  name: 'Test User'
  // TypeScript error if you add invalid fields
})
