How to require a nested json object in Mongoose Schema
Update:You can use the Subdocument apporach
const extraDataSchema = new mongoose.Schema({ brand: { type: String, required: true, minlength: 1, maxlength: 255 }, quantity: { type: Number, required: true, minlength: 1, maxlength: 10 }});const productSchema = new mongoose.Schema({ name: { type: String, required: true, minlength: 1, maxlength: 255 }, extraData: { type: extraDataSchema, required: true }});
Check out the Mongoose documentation, In this link you can find an explanation on how to add required to nested properties().
I believe you will need a sub-schema for the nested properties.
