save uploaded image names in array using mongoose

I am using a 3rd party library for uploading files using Ajax and when they have uploaded I want to store the file names in mongoDB.

This is my Schema:

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const uploadSchema = new Schema({
    imgName: [{
        type: String
    }]
});

module.exports = mongoose.model('Upload', uploadSchema);

I have tried to perform the insert in the success callback for the upload:

    if (data.isSuccess) {
     const uploaded = uploader.getFileList();
     for (const images of uploaded) {
        console.log(images.name);
        const upload = new uploadModel({
            imgName: images.name
        });
         upload.save();
     }

This is storing each image as in individual record in the database with it's own unique ID which isn't what I want. If I for example upload 2 images, I want it to be one record in the database but should look something like this I guess:

_id: ObjectId("123uashjkalh73")
> imgName: Array
  0: "image1.jpg"
  1: "image2.jpg"
__v: 0

So I think there are a few things that are off here.

First, in your schema, 

const uploadSchema = new Schema({
    imgName: [{
        type: String
    }]
});

imgName is noted set to an Array of objects. If you want an array of strings, you can completely skip the object notation with type: String and replace it with [String] (https://mongoosejs.com/docs/schematypes.html#arrays). I think what you want is the following:

const uploadSchema = new Schema({
    imgName: [String]
});

If you are trying to create a new model for this, I simplified the code a bit using reduce

if (data.isSuccess) {
  const uploaded = uploader.getFileList();

  // similar to your loop but i'm just using reduce here. end result is an array of your image names
  const images = uploaded.reduce((acc, image) => [...acc, image.name], []);
  const upload = new uploadModel({
    imgName: images
  });

  upload.save();
}

Hope this helps.
