Add Pin Code Unlock To Your Ionic Framework App

I currently have a few Ionic Framework Android and iOS applications on the market. A common request for these apps have been to have a pin code unlock feature for extra security.

Handling Apache Cordova Events With Ionic Framework

There will often come a scenario where you need to determine when your application enters the device background and comes back into the foreground. For example, let’s say we wanted to require a password every time the application is shown. We would need to listen for when the application enters the foreground.

Lucky for us, we can make use of the Apache Cordova event listeners to accomplish this task.

Create An RSS Reader Using AngularJS And Ionic Framework

This article was designed to help you apply your knowledge of AngularJS and Ionic Framework and create a functional app rather than learn new concepts.

This tutorial should help you with the following concepts:

• Make use of the AngularJS $http service for handling HTTP requests
• Cache HTTP response data on the device for usage offline
• Create data lists in Ionic Framework
• Open external URLs with the Apache Cordova InAppBrowser plugin

Make HTTP Requests In Android And iOS With Ionic Framework

As a modern developer, at some point in time you’re going to find yourself needing to work with a RESTful API. You’re going to need to make HTTP requests to get data into your app or even change data on a remote database.

Lucky for us, making HTTP requests with Ionic Framework is a heck of a lot easier than making them with native code.

The following will show you how to make GET requests for JSON data at some fictional API endpoint. It is for Ionic Framework 1. If you’re looking for how to make HTTP requests using Ionic 2, check here.

Making Android In-App Purchases With Ionic Framework

The future of mobile app design is in the freemium model. No one wants to risk paying for an application that might stink so as a developer it is a good idea to charge for features in your app rather than the app itself.

Using Apache Cordova, Ionic Framework, and the poiuytrez AndroidInAppBilling plugin you can easily handle Android in-app purchases.

Bypass CORS Errors When Testing APIs Locally

Anyone who has worked with a RESTful API using JavaScript knows that testing can be a complete pain if the API owner hasn’t enabled CORS on their server. So what is CORS? According to Wikipedia, it is the following:

Cross-origin resource sharing (CORS) is a mechanism that allows many resources (e.g., fonts, JavaScript, etc.) on a web page to be requested from another domain outside the domain the resource originated from.

Often API owners will leave CORS disabled even though their API is open to the public. In my opinion it doesn’t feel public if the API owner is not allowing requests from all angles.

Here are a few tricks I’ve picked up in regards to bypassing the awful CORS errors you receive in your browser when testing.

Internationalization And Localization With Ionic Framework And Angular Translate

There are roughly seven billion people in the world (7,000,000,000) and roughly 6,500 languages. Lucky for us, Android and iOS does not support all 6,500 of these languages. However, many are supported and this means that when you make an application in your native language, chances are your audience is only going to be a fraction of these people.

Recently I discovered Angular Tranlate, a JavaScript library for AngularJS. It allows you to create translation tables in your web application to quickly switch between depending on the language you desire. When you pair this with Ionic Framework, which supports AngularJS, you have a great way of adding internationalization and localization into your mobile application.
