Creating Data with POST for API

POST endpoints are used to create new data.

The client sends data in the request body, and the server processes it and stores it.

let users = [
  { id: 1, name: 'John' }
];

app.post('/users', (req, res) => {
  const newUser = req.body;

  users.push(newUser);

  res.json(newUser);
});

The server receives the data through req.body and adds it to the collection.

Example request body:

{ "id": 2, "name": "Anna" }

After sending this request, the new user is added.

POST endpoints are used whenever you need to create new records in your application.
