OpenTelemetry Hyper-Express Instrumentation for Node.js

[![NPM Published Version][npm-img]][npm-url] [![Apache License][license-image]][license-image]

This module provides automatic instrumentation for the hyper-express module, which may be loaded using the @opentelemetry/sdk-trace-node package and is included in the @opentelemetry/auto-instrumentations-node bundle. It allows the user to automatically collect trace data and export them to their backend of choice.

If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-node bundle with @opentelemetry/sdk-node for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @pw-tech/instrumentation-hyper-express

Supported Versions

• >=6.0.0

Usage

With opentelemetry

const { HyperExpressInstrumentation } = require('@pw-tech/instrumentation-hyper-express');
const { ConsoleSpanExporter, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();

provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.register();

registerInstrumentations({
  instrumentations: [
    new HyperExpressInstrumentation()
  ],
});

With Datadog (dd-trace)

let service = "your-service";

const tracer = require('dd-trace').init({
  service,
})
const { TracerProvider } = tracer;
const provider = new TracerProvider();
provider.register();

import HyperExpressInstrumentation from "@pw-tech/instrumentation-hyper-express";
const {
  getNodeAutoInstrumentations
} = require('@opentelemetry/auto-instrumentations-node');

new HyperExpressInstrumentation();

ENV

For instrumenting Datadog set below in env

APM_TYPE=DD

For instrumenting Elastic (Default) - APM_TYPE=ELASTIC no need to set in env separately
