It is a tool to solve the problem of resolving serise promise functions with parameter continuously. And there is not a solution but only resolving parallelly.
npm install pacuIt is a tool to solve the problem of resolving serise promise functions with parameter continuously. And there is not a solution but only resolving parallelly.
``
$ npm install --save pacu
Initializing pacu
`js`
var pacu = require("pacu")
To accomplish running promise function one after one is difficult, because the object format of _promise function_ and _promise function with parameter_ are different in js ( issue of anonymous function with parameters ). So that handling this issue needed to push _promise function(not a promise)_ to an array list, which will be resolved:
`js
var genPromist = function(para) {
return new Promise(function(resolve, reject) {
setTimeout(function() {
console.log('para: ', para)
resolve(para * para)
}, 1000)
})
};
var promisesList = [];
promisesList.push(function(){
return genPromist(i)
});
`
`jsUsage
//processing promiseList by series
var pacu = require("pacu")
pacu.series(promisesList).then(function(result) {
console.log("Result series: ", result)
},function(err){
console.log("Error series: ", result)
});
`
`jsUsage closure design
//processing promiseList by series in closure design
var PACU = require("pacu")
var pacu = new PACU(promisesList)
pacu.series(promisesList).then(function(result) {
console.log("Result series: ", result)
},function(err){
console.log("Error series: ", result)
});
