Answer 1

I'm not sure if I understood your question correctly. But if you would like to prevent double names in your EmployeeModel, you can use Unique Indexes like unique: true in your employeemodel.js:

const employeeSchema = new Schema({
  name: {
    type: String,
    required: true,
    unique: true
  }
})

On saving a new model with an existing name, in employeeController.js on await employeeModelData.save() you will get an error, this will be caught with your try-catch.
