heroku和风帆应用程序|崩溃和超时

我有一个非常基本的风帆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”.我有时收到“没有收到数据”.

procfile：

web: npm start

package.json / scripts：

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

配置/ ENV /制作：

module.exports = {

  models: {
    connection: 'mongoDbProd'
  },port: 80,log: {
     level: "silent"
  }

};

任何方向表示赞赏！

解决方法

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.这是一个更多的工作,但它可能是必要的,因为Heroku有自己的超时,可以被Grunt花费太长时间来摧毁你的资产.

我们已经成功使用了heroku-buildpack-nodejs-grunt.您可以按照说明在Heroku应用程序上安装它,然后将任务定义复制到tasks / register / prod.js中以包含heroku：生产任务,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','sails-linker:devTplJade'
  ]);

};

然后最后在你的app.js文件中,替换

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

有：

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