Summary  
This chapter explains how to use a model’s delete method to remove database records in response to HTTP DELETE requests.  

General domain of usage  
User management in a RESTful web API  


To remove data from MongoDB, you use methods provided by the model.

A common method is `findByIdAndDelete`.

```javascript id="z4k1ps"
app.delete('/users/:id', async (req, res) => {
  await User.findByIdAndDelete(req.params.id);

  res.send('user deleted');
});
```

The id is taken from the route parameter, and the matching document is removed from the database.

Example:

 `DELETE '/users/123'`: deletes user with id 123.

This allows your API to remove data when it is no longer needed.
