Better Auth

This walks you through integrating Better Auth (a TypeScript authentication framework) with a NestJS backend and Next.js frontend, using Drizzle ORM and PostgreSQL. You get step-by-step setup for email/password auth, social logins, and plugins like 2FA, passkeys, magic links, and organizations. It's structured in four phases: database schema and migrations, backend configuration with auth handlers, frontend client setup with middleware, then adding advanced features. The checkpoints after each phase are helpful for catching issues early. Good fit if you're building a production app that needs modern auth patterns beyond basic JWT tokens, especially if you want passwordless options or multi-tenant support without rolling everything yourself.
