A Connect middleware and instrumentation that adds Zipkin tracing to the application. Compatible with any server which uses the connect api (Express and Restify).

Usage

Connect

const connect = require('connect');
const {Tracer, ExplicitContext, ConsoleRecorder} = require('zipkin');
const zipkinMiddleware = require('zipkin-instrumentation-connect');

const ctxImpl = new ExplicitContext();
const recorder = new ConsoleRecorder();
const localServiceName = 'service-a'; // name of this application
const tracer = new Tracer({ctxImpl, recorder, localServiceName});

const app = connect();

// Add the Zipkin middleware
app.use(zipkinMiddleware({tracer}));

Express

const express = require('express');
const {Tracer, ExplicitContext, ConsoleRecorder} = require('zipkin');
const zipkinMiddleware = require('zipkin-instrumentation-connect');

const ctxImpl = new ExplicitContext();
const recorder = new ConsoleRecorder();
const localServiceName = 'service-a'; // name of this application
const tracer = new Tracer({ctxImpl, recorder, localServiceName});

const app = express();

// Add the Zipkin middleware
app.use(zipkinMiddleware({tracer}));

Restify

const restify = require('restify');
const {Tracer, ExplicitContext, ConsoleRecorder} = require('zipkin');
const zipkinMiddleware = require('zipkin-instrumentation-connect');

const ctxImpl = new ExplicitContext();
const recorder = new ConsoleRecorder();
const localServiceName = 'service-a'; // name of this application
const tracer = new Tracer({ctxImpl, recorder, localServiceName});

const app = restify.createServer();

// Add the Zipkin middleware
app.use(zipkinMiddleware({tracer}));
