How can you remove all documents from a collection with Mongoose?

Question

I know how to...

• Remove a single document.

• Remove the collection itself.

• Remove all documents from the collection with Mongo.

But I don't know how to remove all documents from the collection with Mongoose. I want to do this when the user clicks a button. I assume that I need to send an AJAX request to some endpoint and have the endpoint do the removal, but I don't know how to handle the removal at the endpoint.

In my example, I have a Datetime collection, and I want to remove all of the documents when the user clicks a button.

api/datetime/index.js

'use strict'; 

var express = require('express'); 

var controller = require('./datetime.controller'); 

var router = express.Router(); 

router.get('/', controller.index); 

router.get('/:id', controller.show); 

router.post('/', controller.create); 

router.put('/:id', controller.update); 

router.patch('/:id', controller.update); 

router.delete('/:id', controller.destroy); 

module.exports = router;

Answer 1

You should use DateTime.remove({}, callback) The empty object will match all of them.
