Nodejs:如何导出多个对象?
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
: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?
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')

回答:
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: {}
