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
