将一个MEAN堆栈完整应用程序部署到Heroku

Question

我已经使用Heroku平台成功部署了一些简单的nodeJS应用程序。

现在我想使用以下方式部署完整的应用程序：

1）MongoLab托管的MongoDB数据库;

2）前端组件的AngularJS + Bootstrap;

这可以部署到Heroku吗？

如果是这样，我需要对git repo和Procfile进行哪些更改才能使其正常工作？

现在，我的github回购看起来像这样：

这是正确的结构吗？

我知道需要监听：process.env.PORT而不是固定的，我也知道使用npm init自动构建package.json。

出于某种原因，我无法部署，我收到此错误日志：
