At the moment I use save to add a single document. Suppose I have an array of documents that I wish to store as single objects. Is there a way of adding them all with a single function call and then getting a single callback when it is done? I could add all the documents individually but managing the callbacks to work out when everything is done would be problematic.

Mongoose | save() Function The save() function is used to save the document to the database. Using this function, new documents can be added to the database.
create() is a shortcut for saving one or more documents to the database. MyModel. create(docs) does new MyModel(doc). save() for every doc in docs.
exports = mongoose. model('User',{ id: String, username: String, password: String, email: String, firstName: String, lastName: String }); It will automatically creates new "users" collection.
Mongoose does now support passing multiple document structures to Model.create. To quote their API example, it supports being passed either an array or a varargs list of objects with a callback at the end:
Candy.create({ type: 'jelly bean' }, { type: 'snickers' }, function (err, jellybean, snickers) { if (err) // ... }); Or
var array = [{ type: 'jelly bean' }, { type: 'snickers' }]; Candy.create(array, function (err, jellybean, snickers) { if (err) // ... }); Edit: As many have noted, this does not perform a true bulk insert - it simply hides the complexity of calling save multiple times yourself. There are answers and comments below explaining how to use the actual Mongo driver to achieve a bulk insert in the interest of performance.
