📖 API Reference

registerOTel(serviceName: string)

Registers the OpenTelemetry provider with an HTTP exporter using the given service name. This is all that is needed to trace your app on Vercel.

• 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.
