A TanStack Start example demonstrating authentication with Auth.js (NextAuth.js).

• TanStack Router Docs
• Auth.js Documentation

To start a new project based on this example, run:

npx gitpick TanStack/router/tree/main/examples/react/start-basic-authjs start-basic-authjs

This example requires environment variables for Auth.js configuration. Copy the .env.example file to .env and fill in your authentication provider credentials:

cp .env.example .env

Edit .env and add your authentication provider credentials.

From your terminal:

pnpm install
pnpm dev

This starts your app in development mode, rebuilding assets on file changes.

To build the app for production:

pnpm build

This example demonstrates how to integrate Auth.js with TanStack Start. Check the source code for examples of:
