📖 API Reference

registerOTel(serviceName: string)

Registers the OpenTelemetry provider with an OTLP exporter using the given service name. This is all that is needed to trace your app on Vercel or any other platform exposing its own OpenTelemetry Collector.

• serviceName: The name of your service, used as the app name in many OpenTelemetry backends.

🧪 What exactly is this package doing

This package utilizes the exports API, enabling us to import the OpenTelemetry SDK in Node only. When you import registerOTel in a file intended for the edge, it returns an empty function because OpenTelemetry doesn't support the edge. However, if you import the same function in a file designed for Node, you'll receive a standard function that sets up the OpenTelemetry SDK correctly.

The OpenTelemetry SDK initialization itself is straightforward. For more details, please see the code.
