Question

当我尝试部署到Heroku时，我的应用程序崩溃了，我正在使用Node。我认为问题是使用Sequelize连接到数据库。

错误代码= H10

我认为这与此处的问题相同： https://github.com/ga-wdi-exercises/project3/issues/127

Index.js：

var port = process.env.PORT || 8000;

db.sequelize.sync().then(() => {
  app.listen(port, () => {
    console.log('Web server started at port 8000!');
  });
});

配置：

module.exports = {
  "development": {
    "username": process.env.DB_USERNAME,
    "password": null,
    "database": "blog-app",
    "host": "127.0.0.1",
    "dialect": "postgres"
  },
  "test": {
    "username": process.env.DB_USERNAME,
    "password": null,
    "database": "blog-app-test",
    "host": "127.0.0.1",
    "dialect": "postgres"
  },
  "production": {
    "username": process.env.DB_USERNAME,
    "password": null,
    "database": "blog-app-production",
    "host": "127.0.0.1",
    "dialect": "postgres"
  }
};

Node，Heroku，应用程序错误，connect.session（）MemoryStore不是为生产环境设计的
