This is the continued series of article on developing a mobile app with Ionic and Angular JS. This post deals with updating and deleting any post on the application. This also explains how to show the loading image by making an Ajax call. While deleting a post, it will show an alert message to confirm whether to delete or not. This post is all about this. Hope you all make use of this series of articles on Ionic and Angular to build your own mobile app.

We have covered most of the topics in building a mobile application using Ionic 3 and Angular JS 4. Today’s topic is to pull in data for news feed from a server and display it on your website. This is suggestible post since it does proper verification at the backend based on token. All it does is, it will verify system token and user token at the backend and then pulls data using feed API url. I have also added an extra code to the previous post for login authentication with PHP Restful API for showing alert messages. Please do follow the below video and code for your understanding.

Here is the continued article on my previous post for creating a welcome page with login and logout. Today’s post explains how to implement login authentication system for your AngularJS 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 secured 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 AngularJS projects. Let’s look into the live demo and follow the below code.

These days, there are no projects that do not have a REST API for creating professional web services. REST ( Representational State Transfer) consists set of guidelines to build a web service, which can be used to modify or view specific information on the web without performing any server side operations. Using RESTful APIs saves huge amount of time. Twitter, Facebook, Google and thousands of companies use REST APIs. This is because REST is the most efficient and widespread standard in the creation of APIs for Internet services.

My previous article gives you an understanding of how to develop any application using RESTful APIs. But, mere implementation of API is not enough for making it more effective. It requires a proper authentication and more security. Here is the article for a secured RESTful API on a token basis. An encrypted token, which is generated based on your site id and ip address is sent with the request call; this token is then be used to authenticate to use a RESTful service in your application. Follow the demo below for your reference.

Two years back we had published an article called create a RESTful Services using PHP, in that most the PHP methods got depreciated. I have been looking for a simple RESTful api framework in PHP, I found few lightweight frameworks called Slim and Epiphany. In this tutorial I had implement a sample user updates RESTful web services project using Slim framework in PHP, it is very simple to implement and only focused on RESTful.

Last some days I have been working with AngularJS, it is a Javascript MVC framework created by Google. Now Angular.js is my personal favorite framework to build better architecture web projects, especially for RESTful web services. It improves HTML with new attributes and expressions in order to define powerful templates directly in your HTML page.

Are you working with multiple devices like iPhone, Android and Web, then take a look at this post that explains you how to develop a RESTful API in Java. Representational state transfer (REST) is a software system for distributing the data to different kind of applications. The web service system produce status code response in JSON or XML format.
