Скачать или смотреть Frontend Authentication with JWT in Nuxt | Full-Stack Web Dev #11

This is Episode #11 of my Nuxt Full-Stack Web Development series.

In the last video, we built backend authentication using bcrypt for password hashing and server routes for /register and /login.
Now, we’re taking the next big step: linking the frontend and backend together using JWT (JSON Web Tokens) for secure user authentication.

You’ll learn how to:
Generate and sign JWT tokens on the server
Store and access tokens securely in the browser (cookies)
Handle login state on the frontend

By the end of this video, your app will have full login persistence, users will be able to register, log in, and stay authenticated.

Subscribe to keep following the series as we continue building this full-stack project step by step.
