Promisify and callbackify functions
npm install beckyBecky converts callback-based functions to promise-based (promisifies) and vice versa (callbackify)
npm install becky --save
Use
js
// basic example
var p = require('becky').promisify // also require('becky').p
var pm = require('becky').promisifyMulti // also require('becky').pm
var cb = require('becky').callbackify // also require('becky').cb// TBD
// use with async + co
var async = require('async')
var co = require('co')
var fs = require('fs')
co(function* () {
var files = ['file1', 'file2', 'file3']
var result = yield p(async.mapLimit)(files, 2, cb(co.wrap(
fucntion* (file) {
content = yield p(fs.readFile)(file)
return file + ': ' + content
}
)))
console.log('Read result:', result)
})
