Native support for SvelteKit's new OpenTelemetry spans

Vercel now directly integrates with SvelteKit's new server-side OpenTelemetry spans.

To get started, activate experimental tracing in SvelteKit:

1
/** @type {import('@sveltejs/kit').Config} */
2
const config = {
3
	kit: { 
4
		experimental: {
5
			tracing: {
6
				server: true,
7
			},
8
			instrumentation: {
9
				server: true,
10
			}
11
		}
12
	}
13
};
14

15
export default config;

And create the tracing instrumentation file with the Vercel OpenTelemetry collector:

1
import { registerOTel } from '@vercel/otel';
2

3
registerOTel({
4
	serviceName: 'my-sveltekit-app'
5
});

Traces generated during tracing sessions will now include the built-in SvelteKit spans. You can also configure other collectors. See the SvelteKit observability docs for more information.
