SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) and references (resource) components.

What problem does it solve?

This Skill provides a comprehensive, ready-to-implement authentication and authorization solution across Next.js 15+/React 18+ frontends and Node.js/FastAPI backends using Better Auth, covering email/password auth, OAuth, RBAC, sessions, and multi-database support.

Core Features & Use Cases

  • Unified authentication framework for Next.js frontends and Node/FastAPI backends with SQL and NoSQL databases.
  • RBAC and permissions to control access across protected routes and APIs.
  • OAuth integration with providers like Google and GitHub, plus session management and security best practices.
  • Use Case: Implement a complete login/signup flow with protected pages and admin controls across a multi-stack application.

Quick Start

  1. Install the Better Auth package for your stack (npm install better-auth or pip install better-auth-python).
  2. Configure a database adapter (SQL or NoSQL) and initialize environment variables (BETTER_AUTH_SECRET, BETTER_AUTH_URL).
  3. Build and protect routes in Next.js, Node.js, or FastAPI using the supplied patterns and references.

Frequently Asked Questions about better-auth-specialist

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up authentication across a Next.js frontend and FastAPI backend?▼

Secure authentication for multi-stack apps is achieved by initializing Better Auth with environment variables and a SQL or NoSQL database adapter. This setup handles front-end and back-end integration, RBAC, and OAuth providers across Next.js and Node.js.

How does role-based access control work for protected routes in Node.js?▼

RBAC secures protected routes by assigning roles to users and enforcing permission checks via middleware. Better Auth applies these patterns across Node.js and FastAPI backends to control access to protected pages and APIs.

Can I use Google and GitHub OAuth with a NoSQL database for user login?▼

Google and GitHub OAuth integrations work with NoSQL databases by configuring the appropriate database adapter in Better Auth. This combination enables secure third-party login flows and session management across your multi-stack application.

What do I need to configure before implementing secure session management?▼

Before implementing session management, you need to install the Better Auth package, configure a SQL or NoSQL database adapter, and set the BETTER_AUTH_SECRET and BETTER_AUTH_URL environment variables. These establish the foundation for secure sessions.

What is the best way to add admin controls to a multi-stack application?▼

Adding admin controls to a multi-stack app is done by implementing RBAC and permission checks. Better Auth provides the framework to define roles and apply access controls across protected routes and APIs in Next.js, Node.js, and FastAPI.

Does Better Auth work with both SQL and NoSQL databases?▼

Better Auth supports both SQL and NoSQL databases by using configurable database adapters. This allows you to implement unified authentication, session management, and OAuth integrations regardless of your chosen database storage solution.
