承诺 CoffeeScript Class
Promisfy CoffeeScript Class
我有这样的 CoffeeScripted class:
class Hair
truncate: () ->
DoAsyncStuffWithMyDB ->
console.log "Async Stuff With My DB completed"
现在我想用这个class,例如:
doghair = new Hair
doghair
.truncate()
.then(() ->
#do stuff
)
我如何使用Bluebird做这样的事情?
自定义方式是这样实现的:
Promise = require('bluebird')
class Hair
truncate: () ->
new Promise((resolve, reject) ->
DoAsyncStuffWithMyDB.create data, (err,res) ->
if err
reject err
else
resolve true
)
现在您的实例化对象可以 then
了。恭喜!
