What problem does it solve?
This guide reduces integration errors and security misconfigurations when adding Better Auth to TypeScript projects by providing clear, operational guidance for authentication, sessions, plugins, adapters, client integration, and middleware.
Core Features & Use Cases
- Environment and config guidance: Use env-driven secrets and base URLs, and know when to supply config fallbacks.
- Adapter and schema rules: Correct ORM model naming, Drizzle pluralization and field mappings, and migration best practices to avoid silent failures.
- Session, client, and middleware patterns: Recommendations for secondary storage, session persistence, cookie strategies, client plugins and global error handlers, and safe middleware header forwarding.
- Plugin and security patterns: How to enable two-factor, organization, passkeys, and trusted provider rules, plus rate limiting and CSRF-safe defaults.
- Use case: Integrating Better Auth into a full-stack TypeScript app with Prisma/Drizzle, Next.js middleware, and an Expo mobile client.
Quick Start
Use this guide to configure Better Auth with env-driven secrets and base URLs, correct ORM model names and Drizzle options, session persistence when using Redis, matching client-side plugins and onAPIError handlers, and safe middleware header forwarding.
