Posted By : Himanshu Goyal | 28-Mar-2016
Intro:The synchronize is nodejs npm module used make the node code synchronized and solve the problem of aysnc programming.it is oposite to the async module of npm and it can good for money relative senstive task.
Problem Facing:I am working on money calculation in MLM(Multi Level Marketing) using neo4j. I have lot of users and i write the code asynchronized for all the user.At same time update hit goes to neo4j and courrept the data and make the calculation wrong.So I search on making the code synchronized in node js.According my reseach two way to make the code synchronized .
- Recursive function
- Synchronized npm module
The recursive function is complex and make lot of effort to make the code synchronized. But synchronize npm is easy and efficent way to make the code synchronized.
Install Procedure:
- npm install synchronize
- var calculateMoney= sync(readFileMethod);//put the reference name of method
Code:
var sync = require('synchronize')
var read = function(a, callback) {
setTimeout(function(){
// remember that callbacks expect (err, result)
callback(null, a)
}, 1000)
}
// We can use the `sync` helper here to avoid using `await()` and `defer()` manually.
read = sync(read);
sync.fiber(function() {
var results = []
results.push(read(1)))
results.push(read(2)))
console.log(results)// results now contains [1,2]
})
