You are storing some LiveView state in the browser. You want to retrieve that saved state as early as possible to improve the user experience.
The approach we used earlier waits for the LiveView to request the client to send the data. In your situation, you know you want the data, so why wait around to be asked for it? Can you have it automatically pushed from the client without being requested? Can you do it in a way that is reusable for other pages and other LiveViews and not just this one page?
This recipe improves the design and even makes it work for multiple LiveViews in the same application!
