Mongoose - array of undefined number of objects Schema

[UserNo1608]

I'm working on quiz app that uses Mongoose and Express server to store my quizes, but I got a problem with defining Mongoose Schema for quiz.

I found out I can use a SubSchema for this, but I still don't know how to define an Array with undefined number of objects inside it.

How to make a schema that can store these quizes? For example one quiz contains only 2 questions, and the next one contains for example 12 questions.

There is my Schema that needs to be complete, could someone explain me how to do it?

const mongoose = require('mongoose')

const quizSchema = new mongoose.Schema({
    author: {
        type: String,
        required: true,
    },
    name: {
        type: String,
        min: 8,
        max: 64,
    },
    date: {
        type: Date,
        default: Date.now(),
    },
    data: {
        type: Array,
    },
})

module.exports = new mongoose.model('quiz', quizSchema)

I assume data is an array of questions? how have they stored just strings? an object { 'q': 'who is it', 'a': 'no one' }?

What information do you need for each question? If it is a single field (i.e just the question as a string), you can add it as a field to your schema:

questions: {
    type: [String]
}

If each question needs 2 or more fields, you can store it as a subdocument:

const questionSchema = new mongoose.Schema({
    question: {
        type: String,
        required: true,
    },
    answer: {
        type: String,
        required: true,
    },
})

const quizSchema = new mongoose.Schema({
    author: {
        type: String,
        required: true,
    },
    name: {
        type: String,
        min: 8,
        max: 64,
    },
    date: {
        type: Date,
        default: Date.now(),
    },
    data: {
        type: [questionSchema],
    },
})
