egg-script不支援 windows，Azure的 App service是Windows base，最省錢的微服務方式

請問還有什麼方式在 windows底下 run eggjs 呢？

egg-scripts

const startCluster = require('egg').startCluster;
startCluster({
  baseDir: '/path/to/app',
  framework: '/path/to/framework',
});

参数可以参考 https://github.com/eggjs/egg-cluster/#options

Egg-script does not support windows, Azure's App service is Windows base, the most cost-effective micro-service

Is there any way to run eggjs under windows?

自己写个入口文件即可，几行代码。

最近 windows 的问题比较多，部署的地方加个简化版的部署方案？

@atian25 @popomore 有相關的文件可參考嗎？
我是先轉成純 koa2的架構執行

下周我看看，加下文档或者改下 egg-scripts

egg-scripts 现在不支持 win 主要是 2 个原因：

启动时轮询日志用了 tail -f，不过这个可以随便找个包。
win 下没有好用的纯 JS 模块去检索 pid
- 之前我用 findprocess 这个包
- wmic 在我本地一台 win10 上报错，似乎是一个 BUG （不过如果你们其他机器没问题，那就可以无视掉）
- 当时还遇到一个问题就是在 appveyor 上精确判断进程的时候，\\ 的转义把我搞晕了。

https://support.microsoft.com/en-us/help/2664203/-invalid-xml-content-error-message-when-you-run-a-wmic-command-in-wind?sd=rss&spid=14019

就目前而言，可以有几种方案：

把我没解决的问题解决掉（可以无视掉部分 win）
使用 vscode 等的 native 版的 pid 模块（就要独立一个工具了，如 egg-scripts-win）
不解决，在文档上面注明如何自己写启动文件即可。

@atian25 方案3不錯，Azure的App Service只是一個很簡易的Windows系統，不具有完整的Win功能，單純的使用node來啟動是可以的。
只是不知道如何不使用 egg-script，單純使用egg的mvc架構來啟動微服務

其实 egg-scripts 没做啥，你看下源码就知道了，

https://github.com/eggjs/egg-scripts/blob/master/lib/cmd/start.js
https://github.com/eggjs/egg-scripts/blob/master/lib/start-cluster

就是配置下环境变量，处理入参，然后丢给 startCluster 而已。

改用 startCluster 啟動

//index.js
const startCluster = require('egg').startCluster;
startCluster({}, () => {
    console.log('started');
  });

// node index.js

看来是因为你的系统阉割版的问题，这个是 Node 自己的 API 来着。

cc @ngot 你那个库，估计要 try catch 兼容下。

解決了！
在 win底下
node-homedir/index.js，直接輸出 os.homedir()

'use strict';

const os = require('os');

module.exports = () => {
  if (process.env.MOCK_HOME_DIR) return process.env.MOCK_HOME_DIR;
  if (os.homedir) {
    return os.homedir();
  }
  return process.env.HOME;
};

服務可以start，不過workers沒有反應，我有寫個 app.js 但沒有任何callback，同樣的code 在mac是正常的

//app.js
module.exports = app => {
    app.beforeStart(async () => {
      // 应用会等待这个函数执行完成才启动
      console.log("beforeStart")
    });
  };

You should set EGG_SERVER_ENV=prod

popomore on 7 Jul 2018

總算解了

step by step

先在本機run egg-init --type=simple bug-report，創建最小模組
修改 node_modules 的 node-homedir

// node-homedir/index.js
'use strict';
const os = require('os');
module.exports = () => {
  if (process.env.MOCK_HOME_DIR) return process.env.MOCK_HOME_DIR;
  if (os.homedir) {
    return os.homedir();
  }
  return process.env.HOME;
};

入口代碼

const startCluster = require('egg').startCluster;
startCluster({}, () => {
    console.log('started');
  });

啟動指令

set EGG_SERVER_ENV=prod && node index.js

Jakevin on 8 Jul 2018

node-homedir 那个可以提个 PR 兼容下，直接改源码是不好的。
