heroku 和风帆应用程序 |崩溃和超时

Question

我有一个非常基本的 Sails 应用程序并在本地运行。当我部署到 Heroku 时，我无法从应用程序获得响应，然后最终得到“应用程序错误”。我有时会收到“未收到数据”。

过程文件：

web: npm start

package.json / 脚本：

  "scripts": {
    "debug": "node debug app.js",
    "start": "sails lift --prod"
  }

配置/环境/生产：

module.exports = {

  models: {
    connection: 'mongoDbProd'
  },

  port: 80,

  log: {
     level: "silent"
  }

};

感谢任何方向！

Answer 1

您还可以为 Heroku 使用专门的 buildpack，在部署时运行 Grunt 任务，然后在 Sails 中为生产环境关闭 Grunt。这需要更多的工作，但它可能变得很有必要，因为 Heroku 有自己的超时，这可能会被 Grunt 花费太长时间来处理您的资产而绊倒。

我们在heroku-buildpack-nodejs-grunt 上取得了成功。您可以按照说明将其安装在 Heroku 应用上，然后将任务定义复制到您的 tasks/register/prod.js 以包含 heroku:production 任务，例如：

module.exports = function (grunt) {

  grunt.registerTask('prod', [
    'compileAssets',
    'concat',
    'uglify',
    'cssmin',
    'sails-linker:prodJs',
    'sails-linker:prodStyles',
    'sails-linker:devTpl',
    'sails-linker:prodJsJade',
    'sails-linker:prodStylesJade',
    'sails-linker:devTplJade'
  ]);

  grunt.registerTask('heroku:production', [
    'compileAssets',
    'concat',
    'uglify',
    'cssmin',
    'sails-linker:prodJs',
    'sails-linker:prodStyles',
    'sails-linker:devTpl',
    'sails-linker:prodJsJade',
    'sails-linker:prodStylesJade',
    'sails-linker:devTplJade'
  ]);

};

最后在你的app.js文件中，替换

sails.lift(rc('sails'));

与：

var config = rc('sails');
if (process.env.NODE_ENV === 'production') {
  config.hooks = config.hooks || {};
  config.hooks.grunt = false;
}
// Start server
sails.lift(config);

使用以下内容创建文件 config/locals.js 为我解决了这个问题：

module.exports = {
   hookTimeout: 30000, // 30 seconds
}

Answer 3

除了设置hookTimeout，确保你有

  migrate: 'alter' 

在 config/models.js 中设置

Answer 4

添加官方 Heroku Node.js 构建包对我有用：https://github.com/heroku/heroku-buildpack-nodejs

在 Heroku CLI 中：

heroku buildpacks:add https://github.com/heroku/heroku-buildpack-nodejs.git

然后：

git push heroku master

一切都应该成功构建，并且您的应用应该在 Heroku 中运行良好。
