You can delete all document in mongodb by simply using db.collectionName.remove( { } )

But if your are using node.js, delete all documents by following way.

MongoClient.connect('mongodb://localhost/mochatests', function(err, db) {
    db.collection('contacts', {}, function(err, contacts) {
        contacts.remove({}, function(err, result) {
            if (err) {
                console.log(err);
            }
            console.log(result);
            db.close();
        });
    });
});

"DeprecationWarning: collection.remove is deprecated. Use deleteOne, deleteMany, or bulkWrite instead." I used deleteMany instead of remove. Eg: db.collectionName.deleteMany ( { } ). Thanks @Radhesh for the original answer. – Nhon Ha Apr 26 '20 at 09:59
