Implementing JWT Authentication with Next.js App Router and Rails API Backend
Unanswered

Hello everyone!
I'm working on a project where I'm using Next.js 14 with the App Router for the frontend and a Ruby on Rails API for the backend. I want to implement JWT (JSON Web Token) authentication to secure my application, but I'm not quite sure how to go about it in the context of the Next.js App Router and the Rails API.
Here's an overview of my setup:
- The Next.js frontend will be responsible for user registration, login, and handling protected routes.
- The Rails API backend will handle user authentication, generate and validate JWT tokens, and provide the necessary endpoints for user management.
I'm looking for guidance on how to properly implement JWT authentication in this architecture. Specifically, I have the following questions:
1. How should I structure my Next.js frontend components to handle user registration and login forms?
2. What is the best way to manage the authentication state in the Next.js frontend? Should I use a context provider or a global state management solution?
3. How can I securely store and retrieve the JWT token on the client-side? Should I use cookies or local storage?
4. How do I protect server-side rendered routes in Next.js and ensure that only authenticated users can access them?
5. What is the recommended approach for making authenticated API requests from the Next.js frontend to the Rails API backend, including sending the JWT token in the request headers?
6. Are there any best practices or gotchas I should be aware of when implementing JWT authentication in this stack?
I'm relatively new to Next.js 14 and the App Router, so any guidance, code examples, or resources you can provide would be greatly appreciated. I want to ensure that I'm following the best practices and implementing authentication securely.
Thank you in advance for your help!

2. imo global state better, because most of time you'll anyway need to store something else there.
about all other questions you probably need to explore supabase auth https://supabase.com/docs/guides/auth/auth-helpers/nextjs
they have ready solution for authentication, so you can check how they did it.
At least if you want fully session based auth.
if jwt only is fine, then next-auth can be fine for you, you'll need to add some logic to preserve your own token in their session for your backend, but overall it's ok solution.
