node.js - node express how to get client cookie

Question

The user enters the domain name, and if it has logged in before, it will go directly to the home page, otherwise it will jump to the login interface, because after logging in, I store the user name in a cookie. Now I want to use cookies to determine if the user is logged in or not.

Introducing the cookie-parser package.

const app = express();
...
const cookieParser = require('cookie-parser');
app.use(cookieParser());
...

Then you should be able to use req.cookies in the routing to get the cookie object
