I would like to know what is the best practice for the following use case: There is a person object:

{
   id: number;
   firstName: string;
   lastName: string;
   phoneNumber: string;
   address: string
   /* more fields */
}

I need to fetch list of people and in the list I only need to display part of the object fields (for example - first and last name), after that the user can choose one from the list which will go to another screen where the person details will be fully displayed (for example - also address, phone number, etc).

Should I fetch from the beginning the whole fields for each person or fetch only necessary fields and fetch the whole data for a specific person only when it is needed?

Are there any best practices rules regarding this?

Every unnecessary field increases computational time, traffic, latency. You should fetch only necessary fields and then wait for client to request more info.
