How do I save the logged in user on the client side?

[jeblaje]

Hello friends I have a question, I am using MySQL for the database and I have the login but once logged in, how do I send a request from the client to identify the user who makes the request??? This for those who program web, would be to save in the localStorage of the web page where I have stored the connected user and with whom I make the requests

 

Or is it that I have to be carrying the user variable everywhere?

Or sent to a file of type client a variable that is always there? but this would imply that this variable was lost due to some error?
