zipkin-instrumentation-fetch

zipkin-instrumentation-fetch

This library will wrap the fetch API. You need to provide your own fetch implementation; it could for example come from window.fetch (in the browser), or node-fetch on Node.js.

Usage

const {Tracer} = require('zipkin');
const wrapFetch = require('zipkin-instrumentation-fetch');

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

const remoteServiceName = 'youtube';
const zipkinFetch = wrapFetch(fetch, {tracer, remoteServiceName});

// Your application code here
zipkinFetch('http://www.youtube.com/').then(res => res.json()).then(data => ...);
