Is there any way to save an array of JSON object to a mongodb with only one call? something like:

Another workaround that I've used. If you are using mongoose with promises, you can do this using Q.

You can start using Q as the default promise for mongoose using the below code:

const mongoose = require('mongoose');
mongoose.Promise = require('q').Promise;

Then you can save an array of documents like below. Let's say we are storing an array of User models, which I've shown in users variable.

Q
  .all(users.map(curr => curr.save()))
  .then((results) => { //do something })
  .catch((err) => { //handle error })

.save() will return a q promise and using array map function, we'll create a promise array using the user models array.
