I have a big JSON array that inside of it there are a lot of objects. I want to insert this take this JSON and create a inside my DB for every object inside the array. I am new to MongoDB and mongoose so I am not sure about the approach. at some place I've read I need to use insert, in some I have read I need to use insertMany and in some I've seen create. currently nothing works. I am trying to do this like so (Get data is a private function that fetches a JSON from a remote api):

const mongoose = require("mongoose");

require("../../models/NFTContract");

const Contract = 

mongoose.model("contracts");



let data= getData();

module.exports = app => {

app.get("/test", (req, res, next) => {

    Contract.create(contracts, (err, docs) => {

      if (err) {

        console.log("err");

      } else {

        console.log("All should be inserted");

  }

});

});

Thanks

Read these docs for some explanation on how insertMany works. Here is the example in the docs:

var arr = [{ name: 'Star Wars' }, { name: 'The Empire Strikes Back' }];

Movies.insertMany(arr, function(error, docs) {});

If you have a JSON, you want to parse it first. Let's say you have this JSON (source):

{"menu": {

    "header": "SVG Viewer",

    "items": [

        {"id": "Open"},

        {"id": "OpenNew", "label": "Open New"},

        null,

        {"id": "ZoomIn", "label": "Zoom In"},

        {"id": "ZoomOut", "label": "Zoom Out"},

        {"id": "OriginalView", "label": "Original View"},

        null

    ]

}}

If you want to insert the items, you would do:

Items.insertMany(JSON.parse(myJson).menu.items, (error, docs) =>

  error ? console.error(error) : console.log(docs))
