Implementation Overview

Web requests are served by Express controllers, and tracing is automatically performed for you by zipkin-js. JavaScript used in the web browser is bundled with browserify.

Running the example

This example has two services: request-zipkin,frontend and backend. They both report trace data to zipkin. To setup the demo, you need to start frontend.js, backend.js and Zipkin.

• frontend: http://localhost:8081/, then call backend. client using rest + zipkin-instrumentation-cujojs-rest.
• request-zipkin:http://localhost:8082, then call backend.client using request, folder it to send info to zipkin.
• This continues the trace and calls the backend (http://localhost:9000/api) and show the result, which defaults to a formatted date.

Next, you can view traces that went through the backend via http://localhost:9411/?serviceName=browser

• This is a locally run zipkin service which keeps traces in memory

Starting the Services

In a separate tab or window, start each of frontend.js and backend.js:

$ node frontend.js
$ node backend.js
$ node request-zipkin.js

Next, run Zipkin, which stores and queries traces reported by the browser and above services.

$ docker run -d -p 9411:9411 openzipkin/zipkin
