Blazor Server Application Global Error Handling

Question

Hello,

I am working on a Blazor Server Application, I want to log errors into the database table and I wonder if there is a single/global catch? Can you please guide me?

Thank you.

Hello,

I Would use the standard .NET ILogger.
injecting ILogger in your components and configuring it at application startup, you can centrally manage logging via configuration in an easy way.

You're talking about logging the errors in a database table, which is fine, but think where to log the errors in case the logging dataabase isn't there.
Maybe make a difference between system errors (like logging database unavailable) and application errors (that are being logged in your database).

This article describes nicely how to implement logging:
https://learn.microsoft.com/en-us/aspnet/core/fundamentals/logging/?view=aspnetcore-6.0

and this article describes how to apply this in Blazor:

Have fun,

Cheers,
