About Buff Book

Buff Book is a repository for a hypertrophy wiki and custom training plan platform. The wiki covers the biology of muscle growth, exercise selection, periodization, and nutrition. Users can submit requests for personalized training plans through an application flow, and an admin dashboard is used to manage requests and upload completed plans to cloud storage.

The site is built on Cloudflare services, including the D1 database and R2 object storage, with Better Auth handling user accounts. The admin dashboard is designed to sit behind Cloudflare Access in production. Running the project locally requires Node.js v18 or later, npm, and the Wrangler CLI. The README describes the project as open source and licensed under CC BY-NC-SA 4.0, which limits use to noncommercial purposes.

Buff Book FAQ

What license applies to the project?
The project is licensed under the Creative Commons Attribution-NonCommercial-ShareAlike License (CC BY-NC-SA 4.0).
How is the admin account set up?
The ADMIN_EMAIL must be set in environment variables and Cloudflare secrets. In production, Cloudflare Access blocks unauthorized users from the setup page at /admin/setup, where the admin password is registered. The backend prevents public signups from claiming ADMIN_EMAIL.
How can the project be run locally?
Clone the repository, run npm install, configure the environment variables from .env.example, apply the D1 migrations locally with Wrangler, and start the development server with npm run dev. The site is then available at http://localhost:4321.
