Creating Data with POST

To store data in MongoDB, you create a new document using a model.

This is usually done in a POST route.

app.post('/users', async (req, res) => {
  const user = new User(req.body);

  const savedUser = await user.save();

  res.json(savedUser);
});

The data comes from req.body. A new instance of the model is created and then saved to the database.

After saving, the stored document is returned as a response.

Example request body:

{ "name": "John", "age": 25 }

This creates a new record in the database.
