Blazor Server and Blazor WebAssembly are two hosting models for Blazor applications. The primary differences lie in their execution environments, latency, and offline capabilities.
Blazor Server runs on the server-side, with UI updates sent over a SignalR connection. It has lower client resource requirements but higher latency due to network roundtrips. Conversely, Blazor WebAssembly executes directly in the browser using WebAssembly, providing better performance and offline support but requiring more client resources.
To decide which model to use, consider these factors:
1. Latency: If low latency is crucial, choose Blazor WebAssembly.
2. Offline capability: For offline functionality, opt for Blazor WebAssembly.
3. Client resources: If targeting less powerful devices or slow networks, Blazor Server may be preferable.
4. Server load: Blazor Server increases server load; if minimizing this is important, select Blazor WebAssembly.
5. Compatibility: Blazor WebAssembly requires modern browsers; for broader compatibility, use Blazor Server.
6. Code sharing: Both models allow code sharing between client and server, but Blazor WebAssembly enables greater flexibility.
