Feathers js-TypeError:app。get不是一个函数

我想从winston logger中的配置文件(config/default.json等)中提取主机和端口。js。

当我尝试使用应用程序时。获取('host'),发生错误。

TypeError: app.get is not a function

配置/默认值。json

{
  "host": "localhost",
  "port": 3030,
  "public": "../public/",
  "paginate": {
    "default": 10,
    "max": 50
  },
}

温斯顿·洛格。js

// How to get app.settings in this file?

const app = require('./app');

console.log(app.get('host'), app.get('port'));//TypeError: app.get is not a function

const logger = expressWinston.logger({
  ...
})

module.exports = logger
