Angular 10 Global is not defined at ..node

问题描述： Angular项目中使用了socketio-client库，

{ "dependencies": { ... "@feathersjs/socketio-client": "^4.4.3", ... }, }

使用：

import socketio from '@feathersjs/socketio-client' @Injectable() export class Socket { public socket: SocketIOClient.Socket public app: any constructor() { this.app = feathers() .configure(socketio(this.socket, {timeout: 20000})) .configure(authentication({path: '/login', storage: window.localStorage})) } }

运行后报错

global is not defined at Object…/node_modules/socket.io-parser/is-buffer.js

说在Object ./node_modules/socket.io-parser/is-buffer.js中没有定义全局变量

解决办法： 在polyfills.ts file中添加

// polyfills.ts (window as any).global = window

参考：Global is not defined at …/node_modules/socket.io-parser/is-buffer.js
