nextjs

The fastest async handler in node.js

Next

Because asynchronous calls suck out your brain without a proper async handler. This one is just 4 lines yet it solves a huge issue.

npm install nextjs
  1. Create a Next Instance: var next = new Next(2, finish)
  2. Then you call next() as many times as you specified in the count. In this example it is 2.
  3. After next was called 2 times, the finish function will be called.
// Include 
var Next = require('nextjs');
// CREATE a Next Instance 
var next = new Next(2, finish);
// Log Start 
console.log('start');
// Will happen after 5 seconds passed 
setTimeout(function(){ console.log('A'); next(); }, 5000); 
// Will happen after 2 seconds passed 
setTimeout(function(){ console.log('B'); next(); }, 2000); 
// Will happen in the end after 5 seconds passed 
function finish(){ console.log('finished'); } 
// output result 
// 0 second => start 
// 2 second => B 
// 5 second => A 
// 5 second => finished
