Good evening, please help me.
I am developing a mobile application and I would like to be able to retrieve data from the page only once: Load data the first time when the page is loaded by the client.
The problem is that when I put my function in the constructor or in ngOnInit, this function is called each time the user loads the page (which I don’t want: I want the data to load only the first time and that’s it). If the user wants new information about the page, he has to refresh the page manually .
Is this possible? Thank you for your help.
