How to properly organize information about new events for the user? On the back/front?

Question

Django

Hello everybody!

There was a following question.
We are developing an application in which new messages from users and new events appear.
Where is the best place to store information about new events?

For example, is it better to register the last call from the user to the back on the back and consider all subsequent events as new and issue this information to the front via the API, or is it better to store information on the front (for example, all newly received messages are considered new)?

And where is the best place to store the user's search history? On the back or front?

Thanks in advance for the information.

Answer 1

when requesting from the front, you can specify the datetime / id of the last message received by the front, and the back will return only newer messages. Accordingly, when receiving messages, the datetime / id of the last received must be stored at the front.
