Node.js项目使用名为CITGM（Canary in the Goldmine）的工具，测试任何重大变化（包括弃用）对大量流行生态系统模块的影响，以在执行这些变化之前提供更多的参考。Node.js v16主要的弃用包括对多个核心模块内部执行process.binding()的运行时弃用，如process.binding(‘http_parser’)。

应用cls-proxify，使得每个request都有相应的child logger。记得安装依赖：npm i cls-proxify cls-hooked
./src/createServer.js
'use strict';
const express = require('express');
const { clsProxifyExpressMiddleware } = require('cls-proxify/integration/express');
const { defaultLogger } = require('./utils/logger');
const requestLogger = require('./middlewares/requestLogger');
const errorHandler = require('./middlewares/errorHandler');
const requestId = require('./middlewares/requestId');
const { CLS_KEY, REQUEST_ID } = require('./constants/log');
const createServer = async () => {
defaultLogger.info('Starting to createServer...');
const app = express();
// skip other middlewares...
app.use(requestId); // use requestId middleware
app.use(requestLogger);
// Integrate pino with CLS.For creating dynamically configured child loggers for each request.
// NOTE: Put any third party middleware that does not need access to requestId before it.
// Details see: https://github.com/keenondrums/cls-proxify
app.use(
clsProxifyExpressMiddleware(CLS_KEY, req => defaultLogger.child({ [REQUEST_ID]: req.id })),
);
// skip... routers
app.use(errorHandler);
return app;
};
module.exports = createServer;
