node.js - 即使使用 Procfile 和特定的 Web 进程，Heroku 也总是从 "npm"开始

Question

无论我是否包含 Procfile，我都会在 Web 进程上启动 Heroku 启动“npm start”。我正在使用 React/Redux 构建一个简单的页面，并使用 webpack 进行捆绑。

实际上我的项目结构是:

/projectName
 /public -->folder create during bundling with bundle.js and new html file 
 /src --> contains React and Redux components 
 .babelrc
 .gitignore
 index.html -->original html
 index.js --> express server (nothing special, just serving public/index.html on the root ("./) request)
 package.json
 Procfile (no extension, uppercase P in the name so no error there)
 webpack.config.js

一切都在本地进行。

Package.json 文件:

/ {
    "name": "redux-heroku",
    "version": "1.0.0",
    "description": "",
    "engines": {
       "node":"6.10.1"
    },

   "scripts": {
        "prod": "webpack -p",
        "start":"node index.js",
        "start:web": "webpack-dev-server"
   },

  "author": "",
  "license": "ISC",
  "dependencies": {
     "babel-core": "^6.25.0",
     "express": "^4.15.3",
     "react": "^15.6.1",
     "react-dom": "^15.6.1",
     "react-redux": "^5.0.5",
     "react-router": "^4.1.1",
     "react-router-redux": "^4.0.8",
     "redux": "^3.6.0",
      "redux-thunk": "^2.2.0"
   },
  "devDependencies": {
      "babel": "^6.23.0",
      "babel-loader": "^7.1.1",
      "babel-preset-es2015": "^6.24.1",
      "babel-preset-react": "^6.24.1",
      "css-loader": "^0.28.4",
      "html-webpack-plugin": "^2.29.0",
      "webpack": "^3.2.0",
      "webpack-dev-server": "^2.5.1"
   }
 }

index.js 表达文件:

var express = require('express');
var app = express(); 
var port = process.env.port || 3000; 

app.use(express.static(__dirname +'/public')); 

app.get('/', function(req, res){
    res.render('index');
})

app.listen(port);

Proc 文件: 网页: Node index.js

所以我删除了heroku上的Procile和push，得到了同样的结果，无论如何我期待着根据这个Stopping Heroku from running npm start + what to run instead?

我有点迷失，谢谢你的见解!!

您想知道何时使用 procfile 还是仅使用 npm 脚本？

Procfile 可以包含其他进程类型。例如，您可以为处理队列中的项目的后台工作进程声明一个。

当未找到 procfile 并且只有有限的脚本可用时，将执行 Package.json 脚本

如果您有自定义脚本，请使用 procfile
