# Supabase + Node.js Skill


Express/Hono patterns with Supabase Auth and Drizzle ORM.

**Sources:** [Supabase JS Client](https://supabase.com/docs/reference/javascript/introduction) | [Drizzle ORM](https://orm.drizzle.team/)

---

## Core Principle

**Drizzle for queries, Supabase for auth/storage, middleware for validation.**

Use Drizzle ORM for type-safe database access. Use Supabase client for auth verification, storage, and realtime. Express or Hono for the API layer.

# Database
DATABASE_URL=postgresql://postgres:postgres@localhost:54322/postgres
```

---

## Configuration

### src/lib/config.ts
```typescript
import { z } from 'zod';
import dotenv from 'dotenv';

dotenv.config();

const envSchema = z.object({
  PORT: z.string().default('3000'),
  NODE_ENV: z.enum(['development', 'production', 'test']).default('development'),
  SUPABASE_URL: z.string().url(),
  SUPABASE_ANON_KEY: z.string(),
  SUPABASE_SERVICE_ROLE_KEY: z.string(),
  DATABASE_URL: z.string(),
});

export const config = envSchema.parse(process.env);
```

---

## Database Setup

### drizzle.config.ts
```typescript
import { defineConfig } from 'drizzle-kit';
import { config } from './src/lib/config';

export default defineConfig({
  schema: './src/db/schema.ts',
  out: './supabase/migrations',
  dialect: 'postgresql',
  dbCredentials: {
    url: config.DATABASE_URL,
  },
  schemaFilter: ['public'],
});
```

### src/db/index.ts
```typescript
import { drizzle } from 'drizzle-orm/postgres-js';
import postgres from 'postgres';
import * as schema from './schema';
import { config } from '../lib/config';

const client = postgres(config.DATABASE_URL, {
  prepare: false, // Required for Supabase pooling
});

export const db = drizzle(client, { schema });
```

### src/db/schema.ts
```typescript
import {
  pgTable,
  uuid,
  text,
  timestamp,
  boolean,
} from 'drizzle-orm/pg-core';

export const profiles = pgTable('profiles', {
  id: uuid('id').primaryKey(),
  email: text('email').notNull(),
  name: text('name'),
  avatarUrl: text('avatar_url'),
  createdAt: timestamp('created_at').defaultNow().notNull(),
  updatedAt: timestamp('updated_at').defaultNow().notNull(),
});

export const posts = pgTable('posts', {
  id: uuid('id').primaryKey().defaultRandom(),
  authorId: uuid('author_id').references(() => profiles.id).notNull(),
  title: text('title').notNull(),
  content: text('content'),
  published: boolean('published').default(false),
  createdAt: timestamp('created_at').defaultNow().notNull(),
});

// Type exports
export type Profile = typeof profiles.$inferSelect;
export type NewProfile = typeof profiles.$inferInsert;
export type Post = typeof posts.$inferSelect;
export type NewPost = typeof posts.$inferInsert;
```

---

## Supabase Client

### src/lib/supabase.ts
```typescript
import { createClient, SupabaseClient, User } from '@supabase/supabase-js';
import { config } from './config';

// Client with anon key (respects RLS)
export const supabase = createClient(
  config.SUPABASE_URL,
  config.SUPABASE_ANON_KEY
);

// Admin client (bypasses RLS)
export const supabaseAdmin = createClient(
  config.SUPABASE_URL,
  config.SUPABASE_SERVICE_ROLE_KEY,
  {
    auth: {
      autoRefreshToken: false,
      persistSession: false,
    },
  }
);

// Verify JWT and get user
export async function verifyToken(token: string): Promise<User | null> {
  const { data: { user }, error } = await supabase.auth.getUser(token);

  if (error || !user) {
    return null;
  }

  return user;
}
```

---

## Type Extensions

### src/types/express.d.ts
```typescript
import { User } from '@supabase/supabase-js';

declare global {
  namespace Express {
    interface Request {
      user?: User;
    }
  }
}

export {};
```

---

## Middleware

### src/middleware/auth.ts
```typescript
import { Request, Response, NextFunction } from 'express';
import { verifyToken } from '../lib/supabase';

export async function requireAuth(
  req: Request,
  res: Response,
  next: NextFunction
) {
  const authHeader = req.headers.authorization;

  if (!authHeader?.startsWith('Bearer ')) {
    return res.status(401).json({ error: 'Missing authorization header' });
  }

  const token = authHe
