This is continues of my previous post about how to remove unused CSS and convert unclear JavaScript to protect your source code in the post-build process. If you are using CSS libraries like Bootstrap, Tailwind CSS, etc.. and sometimes multiple frameworks. But your application components are not using all of the styles and it adds more weight to the application performance. This post will explain how to configure the React post-build process to remove unused CSS and hidden JavaScript files that enhance the application security and definitely improve the app loading time and save the overall bandwidth cost.

Nowadays most applications are developed based on large CSS libraries like Bootstrap, Tailwind CSS, etc.. and sometimes multiple frameworks. But your application components are not using all of the styles and it adds more weight to the application performance. This post will explain the Angular post-build process to remove unused CSS and hidden JavaScript files that enhance the application security and definitely improve the app loading time and save the overall bandwidth cost.

This article is more about understanding the Event Emitters in Angular and Ionic. Data flow is the most important when you build an application to communicate with components. Event Emitters will help you to even bind using @Input @Output decorators. Here is a simple example to display and update the user profile using Angular Event Emitters. For this demo I choose Ionic framework for better experience. Take a quick look at the live demo.

Lazy loading is a design pattern to implement large scale Angular projects. Using this system design we can load the components based on the application need. This way we can increase the application performance. This article is a continues of Angular routing project, please follow the previous parts for better understanding. This will explain how to covert default component-based structure to Angular lazy loading pattern.

PDF documents are a very common form of hypermedia documents. Whether it’s books, bills, or invoices we consume PDF documents on a daily basis. In this article, we are going to learn how to generate PDF documents using Node.js and Worker queue called Kue. PDF generation is used in products such as E-commerce based applications, airline tickets, hotel booking, etc. We can use the same principle which I am going to show you below and apply it to implement the feature.

Are you working with social applications and user profiles? This post is about implementing dynamic routes for Angular application with basic route validations. This article is a part of Angular routing series for better understanding, please check my previous articles. Here you find importing the dynamic route value and validating with a regular expression for protecting the application routes.

Ionic has an excellent Angular framework for creating mobile applications for iOS and Android. Ionic team is planning to launch an update with Angular 6.0 version, right now Ionic 4.0 is in beta development. This post is about using ElectronJS for JavaScript based applications, using this you can convert an application into a Desktop application for MacOS, Windows and Linux. Take a look at this article and follow the steps to generate a desktop application for Ionic.

There are a number of advantages to implementing social login in your web applications. First of all, it best secures the user credentials, the user can use a single login for accessing multiple sites, this can automatically access the user details for further use, and many such. This article is about how to implement the social login with Facebook and Google using Angular and RESTful API. This social login helps to store social data of the logged in user into the database, so that it provides you valid user data like email, name, and others.

There are several payment options available in the market today. PayPal checkout option is one among them. In my previous articles, I have already discussed few payment options - Braintree PayPal using PHP, Payment system and PayPal Express Checkout with PHP and MySQL.

These notifications allow users to get timely updates from sites they love and allow developers to effectively re-engage them with relevant content to increase site’s traffic. Let’s start how this works.

We have already discussed few articles on Ionic. Latest Ionic 3 came up with lazy loading concepts. Changing Ionic apps to use lazy loading significantly boost up the app performance. This actually improves the app speed, instead of loading everything in root application module file. This allows doing the work in sync with when your users want it to happen. This article explains to you how to modify the existing default Ionic app and apply lazy load concepts like working with providers, shared/child components. It process by loading chunks of code such as child components when it’s requested not when the app is loaded. Use this feature and enrich your application. Watch the video, you understand it better.

It is very simple to trigger any camera device and show the resulting output. This has been discussed in my article to take multiple photos with delete action using Ionic and AngularJS. Here is a problem. You can only see the image temporarily, since it has not been stored in any storage. Today’s article will explain to you how to store the captured image in a database, so that you can use it later. I’ll be using RESTful API to achieve this. Look into the demo below and also the code to see how to connect with RESTful API to store any captured image into a database.

We have seen series of posts on developing a mobile application using Ionic and AngularJS. One of my previous articles which deal with insertion and deletion of posts using RESTful API. Similarly, today’s post makes use of RESTful API. These days, a single page web applications are most commonly used ones, because of which there is a need to show loads of data on the same page as we keep on scrolling.

Here is the continued article on my previous post for creating a welcome with login and logout using ReactJS. Today’s post explains how to implement login authentication system for your React JS applications. It will show you how to log in with a user and store the user session, so it deals with token-based authentication. Since we are using token-based authentication, it protects if any unauthorized request is made and notices for a new login if required. This makes your application’s authentication to be more secure compared with any other authentication system. Every user details will be stored in an external database and a PHP based API is used in the backend for handling this authentication. Hope you’ll find it more easily using this as your authentication system in your ReactJS projects. Let’s look into the live demo and follow the below code.

Days back, I have posted an article on how to create a welcome page with proper login and logout using Ionic 3 and Angular 4. Today’s article is to create the same welcome page with ReactJS and ES 6.

Lets see how to set a starting page with navigations using ReactJS and ES 6.

A few days back, I read an article about Google Authentication. A bug was mentioned in the article, that Google login status can be easily accessed by calling out some images. After reading the article, I got an idea that why don't we use this bug in a positive approach to validate user authentication. This same idea has been implemented in this post to do email validation. I have used Google email login system (not OAuth) using Angular 4 CLI project. Take a look at the live demo ( Make sure to login into your Google account in another tab to do this validation).
