Get all items in collection
In order for Mongoose to return a Promise you need to set this accordingly in your Mongoose instance:
const mongoose = require('mongoose');mongoose.Promise = global.Promise;Furthermore, if you want to create multiple documents at once, you should pass an array to the .create method:
let things = [ { "name": "Thing 1" }, { "name": "Thing 2" }, { "name": "Thing 3" }];Thing.create(things).then(newThings => { console.log(newThings);});// Outputs[ { name: 'Thing 1', _id: 57fd82973b4a85be9da73b25 }, { name: 'Thing 2', _id: 57fd82973b4a85be9da73b26 }, { name: 'Thing 3', _id: 57fd82973b4a85be9da73b27 } ]
