Any Pointers on How Can I Speed Up my Node.js Application ?

Performance optimization

I am planning to develop a new web application using Nodejs and I want it to make it faster than usual in order to keep it ahead in the competitive fast web technology.

So can anyone please suggest some possible steps and pointers through which I can speed up my Node.Js application.

Speedup mean serving too many clients without slowing down your server. One response will always take the time it needs, the question is for a response not to wait until another finishes.

You cannot speed up nodejs more than it is capable (assuming you have written the most performant code possible), but you can scale your application.

Changing button text (toggle text) on click in AngularJS

We can make a button behave like a toggling button by making a directive in AngularJS. It is very simple. You just need to bind the attribute and then check the condition.

First create a simple HTML :-

<html>

  <head>

      <link rel="stylesheet" type="text/css" href="css/index.css">

      <link rel="stylesheet" type="text/css" href="css/myApp.css">

      <title>Hello World</title>

  </head>

Promises in Angular.JS

By using Promises we can execute a function asynchronously. we can use promises to specify what to do when a operation is success or failed. We have $q built in keyword in angular js for promises. let's create a example :

.service('drawHomeCardService', function(apiCallFactory, $q) {

  this.getTheLogo = function() {

      var deferred = $q.defer();

      apiCallFactory.getData().success(function(response) {

          var logo         = response[2].businessInfo.logoFilePath;

          var logoFilePath = 'https://oyokeydev.s3.amazonaws.com/' + logo;

          deferred.resolve(logoFilePath);

      }).error(function(response) {

          console.log('Something went wrong');

          deferred.reject('Something went wrong');
