cloudflare-d1

What problem does it solve?

This Skill simplifies building and managing relational databases for Cloudflare Workers, enabling developers to leverage a serverless SQLite database at the edge. It addresses common challenges like SQL injection, performance bottlenecks, and complex migration workflows, allowing you to focus on application logic rather than database infrastructure.

Core Features & Use Cases

• Seamless D1 Integration: Guides you through creating D1 databases, configuring bindings in wrangler.jsonc, and writing type-safe queries from your Workers.
• Robust Migration System: Automates SQL schema changes with wrangler d1 migrations, ensuring consistent database versions across local and production environments.
• Performance & Security Best Practices: Emphasizes prepared statements to prevent SQL injection, batch queries for reduced latency, and indexing for faster data retrieval.
• Use Case: Build a high-performance e-commerce backend where user data and product catalogs are stored in D1. Use batch queries to update inventory efficiently and migrations to safely evolve your database schema as your application grows, all running directly on Cloudflare's global network.

Quick Start

Create a new Cloudflare D1 database named 'my-app-db' and then create a migration file to add a 'products' table.
