This is the link to my code.👆

I want to know how to render the results requested from the server to the web page in real time?
In my code I request the title string from the server and store the result in a variable and then use it in the html. However, when the web page is rendered, the web page is rendered before the result is requested, causing the title variable string to be empty. After requesting the results, the web page has been rendered.

Steps To Reproduce

Expected behavior

If you're using Suspense, which is preferred for data fetching, you can use: https://docs.rs/yew/latest/yew/suspense/fn.use_future.html

The futures example shows how to fetch data without suspense: https://github.com/yewstack/yew/tree/master/examples/futures
