In this video, I use Clerk CLI to set up authentication in a Next.js app and connect it to a Rust backend API built with Axum.

We build a small full-stack authentication project using Next.js, Clerk, Rust, and Axum. You will see how to initialize Clerk with `clerk init`, add login and signup to a Next.js frontend, get the Clerk token, and send it to a Rust API using the Authorization header.

In this tutorial:
- Clerk CLI setup
- Next.js authentication
- Login and signup with Clerk
- Rust backend with Axum
- Protected Rust API route
- Clerk token / JWT flow
- Authorization header with Bearer token

00:48 Clerk CLI installation and project initialization
01:13 Next.js authentication
02:57 Login test with Clerk
03:28 Rust Axum backend
05:20 Rust API button component in Next.js
06:00 Call the Rust API with the Clerk token
06:33 Conclusion

Note: in this demo, the Rust backend reads the Clerk token from the Authorization header. In a production app, the next step would be to fully verify the JWT using Clerk JWKS or a Rust SDK.
