我有一个带有 gruntfile 的基本节点应用程序，并且在进行部署时遇到了一些麻烦。所以我做了一个新的 grunt 任务，做了一些改变。那么部署就好了。

但是现在当我去我的应用程序时。我有一个空白页。它不加载 appConfig.app 目录。

我可能错过了一些我无法弄清楚的大事。我以为 grunt connect 会做线，但似乎 server.js 正在等待一些东西。

注意：我想我在这里不需要 Express。

以下是不同的文件：

  • gruntfile.js
  • 服务器.js
  • 包.js

Gruntfile.js

'use strict';

module.exports = function (grunt) {

require('load-grunt-tasks')(grunt);
require('time-grunt')(grunt);
var modRewrite = require('connect-modrewrite');

// Configurable paths for the application
var appConfig = {
    app: require('./bower.json').appPath || 'app',
    dist: 'dist'
};

//Environment vars
var envConfig = {
    dev: {
        //baseUrl: 'http://localhost:3000',
        loginUrl: 'http://demo.lvh.me:9000',
        uploadUrl: 'anuploadurl/upload'
    },
    prod: {
        baseUrl: 'http://aprodurl',

这是一个巨大而苛刻的调试，但我终于发现了。

它来自我遇到的多个错误和错误：

  1. 节点 server.js 没用
  2. 我研究了 grunt connect 方法并创建了一个生产设置

  3. 我将 grunt serve 拆分为 grunt build 任务和 webconnect 任务

  4. 然后更新 package.json 文件

对 heroku 非常重要：在连接对象上的 Gruntfile.js 中：

 dist: {
        options: {
            port:process.env.PORT, #<=== need to have a dynamic port env for Heroku deployment
            open: true,
            base: '<%= appConf.dist %>'
        }
    }

以下是添加的繁重任务：

// Build the production application
grunt.registerTask('build', 'Compile on dist folder', function () {

    grunt.task.run([
        'clean:dist',
        'ngconstant:production',
        'wiredep',
        'sass',
        'concurrent:dist',
        'autoprefixer:dist'
    ]);
});

// Build the production application
grunt.registerTask('webconnect', 'connect web server', function () {

    grunt.task.run([
        'connect:dist'
    ]);
});

然后在 package.json ：

"scripts": {
  "postinstall": "bower install && grunt build",
  "start": "grunt webconnect"
}
