Quick Reference

Common Tasks

When to Use This Skill

• Setting up Drizzle ORM in a TypeScript project
• Defining database schemas with type safety
• Connecting to PostgreSQL, MySQL, or SQLite databases
• Working with serverless/edge databases (Neon, Supabase, D1, Turso)
• Writing type-safe queries
• Managing database migrations
• Adding validation with Zod/Valibot
• Questions about Drizzle ORM patterns and best practices

How to Navigate

1. Start with references/get-started/ for installation and basics
2. For database setup: Find relevant connect-*.mdx file
3. For schema design: Check references/column-types/ and references/relations/
4. For queries: Use query-specific files (select, insert, update, delete, joins)
5. For migrations: See references/migrate/
6. For validation: Check references/zod.mdx or other validator files
7. For best practices: Browse references/guides/

All files are .mdx (Markdown + JSX) but readable as plain markdown.
