Q: How do I install drizzle-orm-patterns?

Run npx skills add https://github.com/giuseppe-trisciuoglio/developer-kit --skill drizzle-orm-patterns in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/drizzle-orm-patterns/ (personal) or .claude/skills/drizzle-orm-patterns/ (project).

Drizzle ORM Patterns

Overview

Expert guide for building type-safe database applications with Drizzle ORM. Covers schema definition, relations, queries, transactions, and migrations for all supported databases.

When to Use

Defining database schemas with tables, columns, and constraints
Creating relations between tables (one-to-one, one-to-many, many-to-many)
Writing type-safe CRUD queries
Implementing complex joins and aggregations
Managing database transactions with rollback
Setting up migrations with Drizzle Kit
Working with PostgreSQL, MySQL, SQLite, MSSQL, or CockroachDB

Quick Reference

Database	Table Function	Import
PostgreSQL	`pgTable()`	`drizzle-orm/pg-core`
MySQL	`mysqlTable()`	`drizzle-orm/mysql-core`
SQLite	`sqliteTable()`	`drizzle-orm/sqlite-core`
MSSQL	`mssqlTable()`	`drizzle-orm/mssql-core`

Operation	Method	Example
Insert	`db.insert()`	`db.insert(users).values({...})`
Select	`db.select()`	`db.select().from(users).where(eq(...))`
Update	`db.update()`	`db.update(users).set({...}).where(...)`
Delete	`db.delete()`	`db.delete(users).where(...)`
Transaction	`db.transaction()`	`db.transaction(async (tx) => {...})`

Instructions

Identify your database dialect - Choose PostgreSQL, MySQL, SQLite, MSSQL, or CockroachDB
Define your schema - Use the appropriate table function (pgTable, mysqlTable, etc.)
Set up relations - Define relations using relations() or defineRelations()
Initialize the database client - Create your Drizzle client with proper credentials
Write queries - Use the query builder for type-safe CRUD operations
Handle transactions - Wrap multi-step operations in transactions when needed
Set up migrations - Configure Drizzle Kit for schema management

Examples

Example 1: Basic Schema and Query

import { pgTable, serial, text } from 'drizzle-orm/pg-core';
import { drizzle } from 'drizzle-orm/node-postgres';
import { eq } from 'drizzle-orm';

export const users = pgTable('users', {
  id: serial('id').primaryKey(),
  name: text('name').notNull(),
  email: text('email').notNull().unique(),
});

const db = drizzle(process.env.DATABASE_URL);

const [user] = await db.select().from(users).where(eq(users.id, 1));

Example 2: CRUD Operations

import { eq } from 'drizzle-orm';

// Insert
const [newUser] = await db.insert(users).values({
  name: 'John',
  email: 'john@example.com',
}).returning();

// Update
await db.update(users)
  .set({ name: 'John Updated' })
  .where(eq(users.id, 1));

// Delete
await db.delete(users).where(eq(users.id, 1));

Example 3: Transaction with Rollback

await db.transaction(async (tx) => {
  const [from] = await tx.select().from(accounts)
    .where(eq(accounts.userId, fromId));

  if (from.balance < amount) {
    tx.rollback();
  }

  await tx.update(accounts)
    .set({ balance: sql`${accounts.balance} - ${amount}` })
    .where(eq(accounts.userId, fromId));
});

See references/transactions.md for advanced transaction patterns.

Best Practices

Type Safety: Always use TypeScript and leverage $inferInsert / $inferSelect
Relations: Define relations using the relations() API for nested queries
Transactions: Use transactions for multi-step operations that must succeed together
Migrations: Use generate + migrate in production, push for development
Indexes: Add indexes on frequently queried columns and foreign keys
Soft Deletes: Use deletedAt timestamp instead of hard deletes when possible
Pagination: Use cursor-based pagination for large datasets
Query Optimization: Use .limit() and .where() to fetch only needed data

Constraints and Warnings

Foreign Key Constraints: Always define references using arrow functions () => table.column to avoid circular dependency issues
Transaction Rollback: Calling tx.rollback() throws an exception - use try/catch if needed
Returning Clauses: Not all databases support .returning() - check your dialect compatibility
Batch Operations: Large batch inserts may hit database limits - chunk into smaller batches
Migrations in Production: Always test migrations in staging before applying to production
