Any plans to make it Blazor Server-Side compatible?

[CoSJay]

This is exactly what I need (I have no idea why the Blazor folk didn't include it!), but as client-side Blazor isn't released yet we can't use it for production apps -- we're doing everything server-side. Any thought to making this SSB-friendly?

@CoSJay
I'm most accustomed to client-side blzr, let me look into the problem for server side. Thanks!

Please help me on blazor server. Error. Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: blazejewicz.Blazor.BeforeUnload.BeforeUnload Lifetime: Singleton ImplementationType: blazejewicz.Blazor.BeforeUnload.BeforeUnload': Cannot consume scoped service 'Microsoft.JSInterop.IJSRuntime' from singleton 'blazejewicz.Blazor.BeforeUnload.BeforeUnload'.)

[peterblazejewicz]

@jmarinl which version of .net you're on at the moment? (note, this one was never run properly on server-backed blazor version)

Replacing services.AddBeforeUnload(); with services.AddScoped<BeforeUnload>() removes the exception, however the callback doesn't get run when navigating off the page.

This looks like a perfect solution to what I'm trying to do right now, but am running into the same issue as @girlpunk

Has anyone found a solution to using this in a blazor server?

The new dotnet 7 updates regarding blazor implement wich implements 2 methods
1 for internal routing (when the user navigates inside the app)
1 for external routing (when the user navigates outside the app, closes the web page or refreshes)

Starting from ASP .NET 7 you no longer needs to use an external library to do so. You could use the built-in event notifier and component:

• RegisterLocationChangingHandler -> lets you to register a handler that is called before navigating an internal link. It lets you the posibility to cancel navigation.
• NavigationLock component -> registers an beforeunload event listener in the window object of the browser. It's intended for external navigation, tab or window closing.
