How can I handle routing errors in Svelte?

In Svelte, you can handle routing errors by using the onError function in your routes. This allows you to catch errors and display a custom error page.

Can you show me an example of that?

Sure! You can define a route like this:

import { Router, Route, onError } from 'svelte-routing';

onError((error) => {
  console.error('Routing error:', error);
  // Redirect to a custom error page
});

<Router>
  <Route path="/" component={Home} />
  <Route path="/about" component={About} />
  <Route path="*" component={NotFound} />
</Router>

What if I want to log the errors to an external service?

You can modify the onError function to send the error details to an external logging service, like this:

onError((error) => {
  logErrorToService(error); // Your function to log errors
  // Redirect to a custom error page
});
