Question

从反应应用程序（App.js）导入jaeger-client。 import jaegerClient from 'jaeger-client'

得到异常＆＃39; TypeError：_fs2.default.readFileSync不是函数＆＃39;来自/node_modules/jaeger-client/dist/src/thrift.js:168的以下行 source: _fs2.default.readFileSync(_path2.default.join(__dirname, './jaeger-idl/thrift/jaeger.thrift'), 'ascii')

试图解决它。谢谢你的帮助。

完整的package.json如下所示 { "name": "calculator", "version": "0.1.0", "private": true, "homepage": "http://ahfarmer.github.io/calculator", "devDependencies": { "gh-pages": "^1.1.0", "react-scripts": "^1.0.17" }, "dependencies": { "ajv": "^6.4.0", "ajv-keywords": "^3.1.0", "big.js": "^5.0.3", "bufferutil": "^3.0.3", "fs": "0.0.1-security", "github-fork-ribbon-css": "^0.2.1", "hexer": "^1.5.0", "jaeger-client": "^3.10.0", "react": "^16.2.0", "react-dom": "^16.2.0", "react-tracing": "^0.1.5", "thrift": "^0.11.0" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test --env=jsdom", "eject": "react-scripts eject", "deploy": "gh-pages -d build" }, "eslintConfig": { "extends": "./node_modules/react-scripts/config/eslint.js" } }

从https://github.com/ahfarmer/calculator分叉，我正在尝试跟踪每个用户操作（按下按钮）。从react.js应用程序测试跟踪。

Answer 1

node-jaeger-client目前不在浏览器中运行。正在进行work以使jaeger-client浏览器友好。此问题：readFileSync is not a function包含您查看错误消息的相关信息。基本上，您正在尝试使用不包含jaeger-client所需模块的react-scripts运行jaeger-client（nodejs库）。

不是jaeger，能够使用zipkin-simple向zipkin服务器发送痕迹。相关代码位于存储库https://github.com/debmalya/calculator

中

import zipkinSimple from 'zipkin-simple'
const zipkinTracerSimple = new zipkinSimple({
             debug: true,
             host: "localhost",
             port: "9411",
             path: "/api/v2/spans",
             sampling: 1.0,
})

var zipkinSimpleTraceData

zipkinSimpleTraceData= zipkinTracerSimple.getChild(zipkinSimpleTraceData);
    zipkinSimpleTraceData = 
zipkinTracerSimple.sendClientSend(zipkinSimpleTraceData, {
     service: '<service_name>',
     name: "<span_name>"
   })

如何从反应组件中使用jaeger-client？
