Blazor could use the function of detecting the first loading of a component / subpage by the server.
If we use OnInitializedAsync it will work like this:
- Execute code on first entry (server side)
- Will execute the same code again after loading the page or moving dynamically (e.g. to a subpage)
If we have a subpage where the code takes longer to load (e.g. we wait for the API), a problem arises. The first load is delayed by this component.
In case we don't want to be indexed by bots, there should be a function like don't do it on server side. We can do a Skeleton and wait for the task to be done.
It is possible to do this by PersistentComponentState, but it is not convenient and there are problems with many components (you can call it only once)
I propose to do something like this:
protected override async Task OnInitializedAsync()
{
if(AppState.ServerRendering == false){
// Code that does not require rendering during server rendering
}
}or
protected override async Task OnInitializedDynamicAsync(){
// Code that does not require rendering during server rendering
}I also know about the existence of OnAfterRenderAsync but it doesn't render the code on the server side.
Describe the solution you'd like
Let me know what you think, I think letting the developer decide whether the code is to be rendered server-side or not is a good solution. This will prevent the problem of delaying the entire page by, for example, one component.
