角度& StompJS引发业力测试负载失败 [英] Angular & StompJS provokes Karma test load failure

问题描述

我们正在使用Angular 5.2.0，最近我们为WS功能添加了StompJS 2.2.3.

We are using Angular 5.2.0 and we recently added StompJS 2.2.3 for WS features.

  "dependencies": {
    "@angular/animations": "^5.2.0",
    "@angular/common": "^5.2.0",
    "@angular/compiler": "^5.2.0",
    "@angular/core": "^5.2.0",
    "@angular/forms": "^5.2.0",
    "@angular/http": "^5.2.0",
    "@angular/platform-browser": "^5.2.0",
    "@angular/platform-browser-dynamic": "^5.2.0",
    "@angular/router": "^5.2.0",
    "...",
    "stompjs": "^2.3.3",
  },

但是，自添加以来，Karma测试将不会加载错误:

However, since the addition, Karma tests won't load with the error :

ERROR in ./node_modules/stompjs/lib/stomp-node.js
Module not found: Error: Can't resolve 'net' in 'C:\Workspace\Projets\HAW_WEB\common\hubanywhere-angular-common\node_modules\stompjs\lib'
 @ ./node_modules/stompjs/lib/stomp-node.js 14:8-22
 @ ./node_modules/stompjs/index.js
 @ ./src/app/common/service/stomp/stomp.service.ts
 @ ./src/app/common/service/stomp/stomp.service.spec.ts
 @ ./src \.spec\.ts$
 @ ./src/test.ts

似乎我们必须允许karma加载本地的"net"程序包，但是我找不到在karma.conf.js文件中放置的正确配置.

It seems we have to allow karma to load the native 'net' packages, but I can't find the correct configuration to place in the karma.conf.js file.

感谢您的帮助.

推荐答案

请使用 https://github.com/stomp-js/ng2- stompjs (npm @ stomp/ng2-stompjs).

Please use maintained version of stompjs from https://github.com/stomp-js/stompjs (npm @stomp/stompjs). There is also a specialized version for Angular https://github.com/stomp-js/ng2-stompjs (npm @stomp/ng2-stompjs).

它们可以与Webpack，Rollup，RxJS和其他更新的库/工具链一起很好地工作.

These work well with Webpack, Rollup, RxJS and other newer libraries/tool-chain.

这些已在TypeScript中重写，并且所有这些都随类型库一起分发.这些带有指南和示例(请参阅: https://stomp-js.github.io/ ).

These have been re-written in TypeScript and all of these are distributed with type libraries. These come with guides and samples (see: https://stomp-js.github.io/).
