OpenTelemetry Context Zone Peer Dependency
![Apache License](https://img.shields.io/badge/license-Apache_2.0-green.svg?style=flat)
This module provides Zone Context Manager with a peer dependency for zone-js for Web applications.
If you use Angular you already have the zone-js and you should use this package.
If you don't have your own zone-js please use @opentelemetry/context-zone
Installation
npm install --save @opentelemetry/context-zone-peer-dep
Usage
import { ConsoleSpanExporter, SimpleSpanProcessor } from '@opentelemetry/tracing';
import { WebTracer } from '@opentelemetry/web';
import { ZoneContextManager } from '@opentelemetry/context-zone-peer-dep';
const webTracerWithZone = new WebTracer({
contextManager: new ZoneContextManager()
});
webTracerWithZone.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
const span1 = webTracerWithZone.startSpan('foo1');
webTracerWithZone.withSpan(span1, () => {
console.log('Current span is span1', webTracerWithZone.getCurrentSpan() === span1);
setTimeout(() => {
const span2 = webTracerWithZone.startSpan('foo2');
console.log('Current span is span1', webTracerWithZone.getCurrentSpan() === span1);
webTracerWithZone.withSpan(span2, () => {
console.log('Current span is span2', webTracerWithZone.getCurrentSpan() === span2);
setTimeout(() => {
console.log('Current span is span2', webTracerWithZone.getCurrentSpan() === span2);
}, 500);
});
console.log('Current span is span2', webTracerWithZone.getCurrentSpan() === span2);
}, 500);
console.log('Current span is span1', webTracerWithZone.getCurrentSpan() === span1);
});
