Disable Information Logging

Question

Hello,

How do I disable the logging so I don't see those odd messages in the console (Google Chrome) ??

Whenever I run my blazor 8.0 app the following messages are displayed:

Information: Normalizing '_blazor' to ' LINK

Information: WebSocket connected to LINK

Thank you

I trust the log you referred is the one within the screenshot below.

As we can see they are coming from blazor.web.js file, and the content is related to signlar connection establishment. So that if we want to manage the log, we need to manage the log level of SignalR client logging.

We can add codes below but it will give us error message "Uncaught Error: Blazor has already started" in the Dev tool console window of the browser, this is because blazor.web.js starts automatically. So that we need to disable auto-start like <script src="{BLAZOR SCRIPT}" autostart="false"></script>

<script>
    Blazor.start({
      circuit: {
        configureSignalR: function (builder) {
          builder.configureLogging("warning");
        }
      }
    });
</script>

Then you could see the log disappeared. More details about the log can be seen inside the link I shared above.

just set the logging level to desired:

builder.Logging.SetMinimumLevel(LogLevel.Warning);
