## Analysis
- Current setup: [status]
- Performance issues: [findings]
## Implementation
1. [Specific code changes]
2. [Migration strategy]
3. [Performance optimizations]
## Verification
- [ ] Schema validation
- [ ] Connection test
- [ ] Query performanceTechnical Standards
Connection Management
- Use environment variables for DATABASE_URL
- Implement proper lifecycle in serverless functions
- Handle connection errors with retry logic
Schema Design
- Design normalized, efficient schemas
- Use appropriate Postgres types (JSONB, arrays, enums)
- Implement proper constraints and indexes
Query Optimization
- Use prepared statements for repeated queries
- Implement batch operations efficiently
- Optimize for Neon's serverless characteristics
Always provide working code examples with clear explanations and verification steps.
Neon Serverless Guidelines
Installation
bash
npm install @neondatabase/serverless drizzle-orm
npm install -D drizzle-kitConnection Setup
typescript
// src/db.ts
import { drizzle } from "drizzle-orm/neon-http";
import { neon } from "@neondatabase/serverless";
const sql = neon(process.env.DATABASE_URL!);
export const db = drizzle({ client: sql });Schema Design
typescript
import { pgTable, serial, text, timestamp, jsonb } from "drizzle-orm/pg-core";
export const usersTable = pgTable("users", {
id: serial("id").primaryKey(),
name: text("name").notNull(),
email: text("email").notNull().unique(),
metadata: jsonb("metadata"),
createdAt: timestamp("created_at").defaultNow(),
});Query Optimization
typescript
// Efficient batch operations
export async function batchInsertUsers(users: NewUser[]) {
return db.insert(usersTable).values(users).returning();
}
// Prepared statements for repeated queries
export const getUserByEmail = db
.select()
.from(usersTable)
.where(eq(usersTable.email, placeholder("email")))
.prepare();Transaction Handling
typescript
export async function createUserWithProfile(user: NewUser, profile: NewProfile) {
return await db.transaction(async (tx) => {
const [newUser] = await tx.insert(usersTable).values(user).returning();
await tx.insert(profilesTable).values({
...profile,
userId: newUser.id,
});
return newUser;
});
}Error Handling
typescript
export async function safeQuery<T>(operation: () => Promise<T>): Promise<T> {
try {
return await operation();
} catch (error: any) {
if (error.message?.includes("connection pool timeout")) {
console.error("Neon connection timeout");
}
throw error;
}
}
