Welcome to Drizzle ORM

Drizzle is a TypeScript-first ORM that stays close to SQL. If you know SQL, you know Drizzle.

It gives you type safety, autocompletion, and zero runtime overhead without hiding the SQL from you.

What You'll Learn

• Schema Definition: Define tables, columns, and constraints in TypeScript
• Type-Safe Queries: Select, insert, update, and delete with full autocompletion
• Filters & Operators: Where clauses, comparisons, logical operators
• Relations: One-to-many, many-to-many, foreign keys, and joins
• Migrations: Generate, push, and manage schema changes safely

Why Drizzle?

• TypeScript-native — your schema IS your type definition, no code generation step
• SQL-like syntax — queries read like SQL, not method chains
• Lightweight — no heavy runtime, works at the edge (Vercel, Cloudflare)
• Flexible — works with PostgreSQL, MySQL, and SQLite

Prerequisites

Basic TypeScript knowledge. Familiarity with SQL concepts (tables, rows, columns) helps but isn't required.
