node.js - Node : How to export multiple objects?

Question

我是 Nodejs 新手。如何导出多个对象？例如

fs = require("fs")
Sequelize = require 'sequelize'

module.exports = (config)->
  sequelize = new Sequelize(
    config.database.name
    config.database.username
    config.database.password
    config.database.options
  )

  fs.readdirSync(config.root+'/server/models/').forEach (file)->
    module.exports['Page'] = sequelize.import(config.root + '/server/models/' + file) # --> export this model 
  sequelize # --> export this object

我想使用 Page 模型:

Page = require('./models').Page

我想使用 Sequelize 对象，例如:

Sequelize = require('./models').Sequelize

谢谢你的建议:D

更新:解决方法如下:

fs = require("fs")
Sequelize = require 'sequelize'

module.exports = (config)->
  @Sequelize = new Sequelize(
    config.database.name
    config.database.username
    config.database.password
    config.database.options
  )

  fs.readdirSync(config.root+'/server/models/').forEach (file)->
    @Page = sequelize.import(config.root + '/server/models/' + file)
  @

但我还有一个问题。如何动态分配模型？

已更新通过以下方式解决了第二个问题:

fs = require("fs")
Sequelize = require 'sequelize'

module.exports = (config)->
  @Sequelize = new Sequelize(
    config.database.name
    config.database.username
    config.database.password
    config.database.options
  )

  # @Page = sequelize.import(config.root + '/server/models/page')
  fs.readdirSync(config.root+'/server/models/').forEach (file)->
    str = file.replace('.coffee', '')
    model = str.charAt(0).toUpperCase() + str.slice(1)
    @[model] = @Sequelize.import(config.root + '/server/models/' + file) if ~file.indexOf('.coffee')
  @

只需将它们包装在一个对象字面量中。在纯 JS(没有 CoffeeScript)中将是:

module.exports = {
    Page: {}, // or whatever you want to assign it to
    Serialize: {} // again, set it to what you like
};

在 coffeescript 中你使用缩进，除非你想制作一个空对象:

module.exports =
  Page: {},
  Serialize: {}
