Description
Astro DB — defineDb, defineTable, column types, CRUD with db.select/insert/update/delete, db/config.ts, db/seed.ts, Turso for production, type-safety, integration with Astro Actions. Use for any database operation in an Astro project.

Astro DB

Type-safe SQL database built into Astro, powered by libSQL/Turso. Use for structured data without external backend services.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

  1. fuse-ai-pilot:explore-codebase - Check existing db/config.ts, tables, and Actions
  2. fuse-ai-pilot:research-expert - Verify Astro DB API via Context7/Exa
  3. mcp__context7__query-docs - Check Astro 6 DB docs for column types and CRUD

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

When to Use

  • Storing structured data (comments, users, posts, forms)
  • Building full-stack Astro apps without external DB setup
  • Combining with Astro Actions for type-safe form handling
  • Deploying to production with Turso (libSQL cloud)
  • Seeding development data for local testing

Architecture

db/
├── config.ts   # Schema definition (defineDb, defineTable)
└── seed.ts     # Development data seeding

Core Concepts

Schema Definition

Define tables in db/config.ts using defineDb and defineTable. Export tables for use in pages and actions. Column types: column.text(), column.number(), column.boolean(), column.date(), column.json().

CRUD Operations

Import db and table from astro:db. All operations are async and type-safe based on your schema definition.

Turso for Production

Set ASTRO_DB_REMOTE_URL and ASTRO_DB_APP_TOKEN environment variables. Run astro db push to sync schema to Turso. Use astro db execute to run seed scripts against remote DB.

Actions Integration

Combine with astro:actions for end-to-end type safety: Zod input validation → DB operation → typed response.

Reference Guide

Concepts

| Topic | Reference | When to Consult | |-------|-----------|-----------------| | Schema Definition | schema-definition.md | Table structure, column types | | CRUD Operations | crud-operations.md | select, insert, update, delete | | Seed Data | seed-data.md | db/seed.ts, remote seeding | | Turso Production | turso-production.md | Deployment, env vars, push | | Actions Integration | actions-integration.md | Type-safe form → DB flow |

Templates

| Template | When to Use | |----------|-------------| | db-config.md | Complete db/config.ts + seed.ts | | crud-example.md | Full CRUD with Actions |

Best Practices

  1. Export tables from config.ts - Import in pages and actions
  2. Use Actions for mutations - Type-safe with Zod validation
  3. .returning() after insert - Get back inserted rows
  4. Push before deploy - Run astro db push in CI/CD
  5. Turso free tier - 500 databases, generous for production
