Implementing Toggleable Layer Activation in TypeScript

import { layer as webSdkLayer, type Configuration } from "@effect/opentelemetry/WebSdk";

const SpansExporterLive = Layer.suspend(() => {
  if (env.ENV !== "local") return Layer.empty;

  return webSdkLayer(
    (): Configuration => ({
      resource: {
        serviceName: "serviceName",
      },
      spanProcessor: new BatchSpanProcessor(
        new OTLPTraceExporter({
          url: "http://localhost:4318/v1/traces",
        }),
      ),
    }),
  );
});

export const MyRuntime = ManagedRuntime.make(Layer.mergeAll(..., SpansExporterLive))
