CodePudding user response：

Initially you have to create the table schema like this:

const mongoose = require('mongoose');

// Health Schema
const HealthSchema = new mongoose.Schema({
    name: {
        type: String,
    },
    protein: {
        type: String,
    },
  carbs: {
    type: String,
  },
  calorie: {
    type: String,
  },
  fats: {
    type: String,
  },
  ingredients: {
    type: object,
    default: {
      salt: '',
      fibre: ''
    }
  },
});

module.exports = mongoose.model(
    'health',
    HealthSchema
);

Here ingredients objects have priorly set the keyname. So you have to just pass the value at the time of creation.

I'm gonna skip alot of things here.

In your schema do something like,
ingredients:[String]

when creating new data do something like

const healtData= await new healtData({... the data here})

the do something like this before calling save

healthData.ingredients.push(ingredient)

healthData.save()
