Creating mongoose schema that contains array of Objects

Question

How do I create a mongoose schema that has the following structure

 {
       data: {
        name: "John doe",
        attributes: [
          {
            text: "Sample text",
            created_at: "2018-08-23"
         },
        {
            text: "Sample text 2",
            created_at: "2018-08-23"
         }
        ],
       created_at: "2018-08-23"
     }
}

This can simply be done with Arrays of Objects instead of creating New Schemas. I don't know if there might be some implications for the optimization.

    attributes: [{
    text: String,
    created_at: Date
}],

This is following the official Mongoose documentation.

You can try this

const sampleSchema = new mongoose.Schema({
    data: {
        type: dataSchema
    }
});

const dataSchema = new mongoose.Schema({
    name: String,
    attributes: [attributeSchema],
    created_at: Date
});

const attributeSchema = new mongoose.Schema({
    text: String,
    created_at: Date
});

Tried that but the created_at doesn't reflect

Change type as per your requirements. You can use Date.now()

As per the Mongoose docs, mongoose has a timestamps property that automatically generates timestamps mongoosejs.com/docs/guide.html#timestamps. My issue is that the timestamp gets applied to the main object but not to the array of objects.

I missed a property in dataSchema . I have updated the snippet. Try the snippet now.
