import { XMLHttpRequestInstrumentation } from '@opentelemetry/instrumentation-xml-http-request';
import { ZoneContextManager } from '@opentelemetry/context-zone';
import { registerInstrumentations } from '@opentelemetry/instrumentation';

const providerWithZone = new WebTracerProvider();
providerWithZone.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

providerWithZone.register({
  contextManager: new ZoneContextManager(),
});

registerInstrumentations({
  instrumentations: [
    new XMLHttpRequestInstrumentation({
      propagateTraceHeaderCorsUrls: ['http://localhost:8090']
    }),
  ],
});


const webTracerWithZone = providerWithZone.getTracer('default');

/////////////////////////////////////////

// or plugin can be also initialised separately and then set the tracer provider or meter provider
const xmlHttpRequestInstrumentation = new XMLHttpRequestInstrumentation({
  propagateTraceHeaderCorsUrls: ['http://localhost:8090']
});
const providerWithZone = new WebTracerProvider();
providerWithZone.register({
  contextManager: new ZoneContextManager(),
});
xmlHttpRequestInstrumentation.setTracerProvider(providerWithZone);

// and some test
const req = new XMLHttpRequest();
req.open('GET', 'http://localhost:8090/xml-http-request.js', true);
