Sentry tracing integration

[XiNiHa]

There are various Sentry integrations for SPA routers with tracing support, a TanStack Router integration for example. Having one for Stackflow would be very helpful for Sentry users.
Since we already have event-driven plugin architecture, I guess it'd be pretty straightforward to make a plugin for it.

Thanks for the great suggestion Xiniha!

I've had a quick look at it, but I'm not sure what the benefits of integrating router framework with Sentry would be. It looks like it adds navigation tracing, but would that be a big help in tracking errors?

I believe it can be helpful for both performance monitoring and debugging.

• Tracking routing and dataloading performances would be important to understand overall performance characteristics of application.
• While debugging, it's quite useful to know which route a user was on. However, the builtin tracing feature of Sentry relies on History API tracking and therefore doesn't work well with Stackflow - especially when history sync extension is not / can't be used.

Okay, that makes sense now that I understand the situation “history sync extension can't be used”. I think it's a good suggestion, and since we don't have the resources right now, I'd be happy if you could contribute to it yourself

I'll look into it when I get some spare time 😅 If anyone is interested in the feature, let me know so I can bump up the priority!
