Session Cookies in Node.js

Session Cookies (in node js) is a Node.js topic. In plain words you use it for login token in protected /admin. Don’t start with a slogan — start with that picture.

Smallest example: verify token in middleware. Type it, run it, and say what you see. If you can do that from memory, you know Session Cookies (in node js).

From the example next to this theory — Session Cookies in Node.

Trap — storing JWT in localStorage as the only plan. Fix that before you talk about advanced Node.js.

Viva — what is Session Cookies (in node js)? Then show verify token in middleware. Then name the trap.

Exam tip

What is Session Cookies (in node js)? Show this: verify token in middleware. Trap: storing JWT in localStorage as the only plan.

Example

// Session Cookies in Node.js
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

console.log(findUser(2));
console.log(users.map((u) => u.name));

Session Cookies in Node.js: find user 2, then list names. Say both prints.
