如何在每次访问路径/页面时阻止控制器中的其余API调用

I am calling some rest API(s) in my Angular app to get data from server and display it on page (ex: home page). But every time I visit the page, the API is hit, and data is fetched and displayed, because in my Controller, I am calling the rest service. Is there any 'best' way I can 'save' the data on first call and then, when user visits the same page, display the 'saved' data instead of hitting rest services again and again?I am calling some rest API(s) in my Angular app
