OpenTelemetry Context Zone with peer dependency for zone.js
Package description
@opentelemetry/context-zone-peer-dep is a package that provides context management capabilities using Zone.js. It is part of the OpenTelemetry project, which is a set of APIs, libraries, agents, and instrumentation to provide observability for applications.
Context Management
This feature allows you to manage context using Zone.js. The code sample demonstrates how to set the global context manager to use ZoneContextManager, create a new context, and run a function within that context.
const { context, setGlobalContextManager } = require('@opentelemetry/api');
const { ZoneContextManager } = require('@opentelemetry/context-zone-peer-dep');
// Set the global context manager to use ZoneContextManager
setGlobalContextManager(new ZoneContextManager());
// Create a new context
const ctx = context.active().setValue('key', 'value');
// Run a function within the context
context.with(ctx, () => {
console.log(context.active().getValue('key')); // Outputs: 'value'
});@opentelemetry/context-async-hooks provides context management using Node.js async_hooks. It is similar to @opentelemetry/context-zone-peer-dep but is designed for use in Node.js environments, leveraging the async_hooks API for context propagation.
zone.js is a library that provides execution context tracking for JavaScript. It is the underlying library used by @opentelemetry/context-zone-peer-dep for context management. While zone.js is more general-purpose, @opentelemetry/context-zone-peer-dep integrates it specifically for OpenTelemetry context management.

Readme
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
npm install --save @opentelemetry/context-zone-peer-dep
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()));
// Example how the ZoneContextManager keeps the reference to the correct context during async operations
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);
});
// there is a timeout which still keeps span2 active
console.log('Current span is span2', webTracerWithZone.getCurrentSpan() === span2);
}, 500);
console.log('Current span is span1', webTracerWithZone.getCurrentSpan() === span1);
});
