Blazor Server description
Components are executed on the server. UI updates, event handling, and JavaScript calls are handled over a SignalR connection using the WebSockets protocol.
On the client, the Blazor script establishes the SignalR connection with the server.
The state on the server associated with each connected client is called a circuit.
Circuits aren't tied to a specific network connection and can tolerate temporary network interruptions and attempts by the client to reconnect to the server when the connection is lost.
How Blazor Server is working
Whenever the browser triggers a registered event (e.g. click on a button), it sends to the server a message saying that the button was clicked.
The server executes the code associated with the event, manipulating the server's copy of the page, and replies a JSON message with the delta between server and client.
Blazor Server Pros / Cons
- .NET-based web framework that uses the C# and Razor languages.
- easy integration of Javascript libraries with JSInterop.
- Performances: every client actions are routed to the server and will be delayed by the network latency and will use bandwidth.
- No offline support
- Reduced scalability: with SignalR there is a limit to how many simultaneous connections can be handled from the clients.
