Prerequisites

Required

• Cloudflare account -- a free tier account works. You'll need access to Workers, D1, R2, Vectorize, Workers AI, and Browser Rendering.
• Node.js 18+ -- required to run the build and deployment tools.
• npm -- comes with Node.js.
• Wrangler CLI -- Cloudflare's command-line tool for managing Workers projects.

Install Wrangler:

npm install -g wrangler

Authenticate with your Cloudflare account:

wrangler login

Optional

• GitHub OAuth app credentials -- for GitHub social login. Create an OAuth app in your GitHub Developer Settings. Set the callback URL to https://your-domain/api/auth/callback/github.
• Google OAuth app credentials -- for Google social login. Create credentials in the Google Cloud Console. Set the redirect URI to https://your-domain/api/auth/callback/google.

If you skip the OAuth setup, users can still sign up with email/password.
