mongoose delete request
// The "todo" in this callback function represents the document that was found.
// It allows you to pass a reference back to the client in case they need a reference for some reason.
Todo.findByIdAndRemove(req.params.todoId, (err, todo) => {
// As always, handle any potential errors:
if (err) return res.status(500).send(err);
// We'll create a simple object to send back with a message and the id of the document that was removed
// You can really do this however you want, though.
const response = {
message: "Todo successfully deleted",
id: todo._id
};
return res.status(200).send(response);
});
