Absolutely minimal authentication with Next.js and a Micro auth server

Next Minimal Auth

This project demonstrates a very small amount of code to allow Next.js to authenticate requests on both the server and the client. This is done by saving a JWT in a cookie on the Next.js host.

The JWT is created by a separate Micro server (server/index.js).

The Next app has two pages.

1. index.js, where the user can login and logout.
2. about.js, which requires the user to be logged in (and redirects to /index if not).

The Micro server has two methods. The idea would be to replace this with your own, smarter auth server.

1. /login, which always succeeds and returns { jwt: "...", user: { id: "..." } }.
2. /me, which only succeeds if there is an Authorization: Bearer ... header with a valid JWT.

Running locally

To start the Next.js server:

yarn
next dev

To start the Micro server:

cd server/
yarn
micro-dev -p 3004     # localhost:3004 is the default server address
