Stale-While-Revalidate for Blazor
SWR .NET
Cache first. Revalidate in the background.
Keep every component in sync.
@inject ISwr Swr
@implements IDisposable
@if (result?.Data is not null)
{
<h2>@result.Data.Name</h2>
<span>@result.Data.Email</span>
}
@code {
private SwrResult<User>? result;
protected override async Task OnInitializedAsync()
{
result = await Swr.GetAsync<User>("/api/me");
}
public void Dispose() => result?.Dispose();
}Stale
Return cached data instantly. Your UI is never blocked waiting for the network.
Revalidate
Fetch fresh data in the background. No loading spinners, no layout shifts.
Update
Swap in the latest data. Every subscriber re-renders automatically.
Global Cache
Share data across components. One fetch populates the cache, every subscriber stays in sync without prop drilling.
Auto Revalidation
Data refreshes on window focus, network reconnect, and configurable intervals. Always fresh, zero effort.
Blazor Native
Built for Blazor Server and WebAssembly from the ground up. Integrates with the component lifecycle naturally.
Type Safe
Full generic type support with compile-time checking. Fetcher return types flow through the entire pipeline.
