Nodejs：如何导出多个对象？

Question

我是Nodejs的新手。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类似的模型：

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

我想使用Sequelize类似这样的对象：

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

谢谢你的建议：D

更新 ：解决以下方法：

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)
  @

但是我还有另一个问题。如何动态分配模型？

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')
  @

只需将它们包装在对象文字中即可。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，您使用缩进，但要创建空对象时除外：

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