Create A Mobile App From Your Angular Web App With NativeScript

Angular is all the rage right now. It is a significant step in the right direction from its predecessor AngularJS 1 for numerous reasons, one being its decoupling from the document object model (DOM). This separation allows for applications to be built beyond the web browser. Take for example, the mobile development framework NativeScript, which allows you to develop native Android and iOS applications. There is no DOM in this framework, but yet we can still use Angular to develop our applications.

We’re going to take a look at how to take an Angular web application and bring it to mobile using NativeScript.

Build A Password Manager For Android And iOS Using Ionic 2

Have you ever wanted to build your own password manager? Maybe you don’t trust the password management tools that already exist, or maybe you just want the experience. I personally use the tool 1Password, but many of my friends don’t trust the applications that exist on the market. It is a valid concern that they have. What if the password managers that exist are using an ancient or obsolete DES specification or similar, rather than the modern AES? What if the master passwords are not being hashed with a strong Bcrypt algorithm?

Not too long ago we created a password manager using the NativeScript framework, but what if we wanted to build one with a different technology.

We’re going to see how to build a password manager that makes use of the AES specification using Ionic 2 and Angular. This application will work for both Android and iOS and look great on both.

Build An RSS Reader Mobile App With NativeScript And Angular

Rich site summary (RSS) feeds are very common on blogs or sites that have a publication type feed. These feeds are in XML format and have information such as the publication title, a summary, or other bits of information that is rather useful. There are plenty of mobile applications on Google Play and iTunes that support the aggregation of RSS feeds, but have you ever wanted to build your own? Maybe you want to create your own news application based on your own algorithms, or maybe your company has a mobile application and you’d like to include a blog section to the mobile app. Whatever the need may be, doing so is not difficult.

We’re going to see how to use Angular, Yahoo’s YQL language, and NativeScript to build a fully native RSS feed reader for Android and iOS.

Using Local Notifications In Your Ionic 2 Mobile App

A little more than a year ago I wrote a tutorial regarding using local notifications in an Ionic Framework Android and iOS application, but Ionic Framework and AngularJS is rapidly becoming a thing of the past. Lately, anything Angular is all the rage and that includes frameworks that use it like Ionic 2. This inspired me to update my previous tutorial for the latest and greatest.

Let’s take a step back though. Why would one want to use local notifications in their mobile application? Well, one example might be in iBeacon detection. An iBeacon comes into range and a notification might show. That is just one of many examples. Let’s also not confuse local notifications with push notifications. Local notifications have no interaction with a service like Firebase Cloud Messaging (FCM) or Apple Push Notification Service (APNS).

We’re going to see how to schedule notifications and perform tasks based on various actions around the notifications.

Working With Shared Providers In An Ionic 2 Mobile App

When developing an Ionic 2 application there are often scenarios where it probably isn’t a good idea to include repetitive source code in multiple application pages. A common example of this would be when it comes to database interaction in an Ionic 2 application. Sure you could establish a connection to the database on every page and query it, but it would probably make more sense to use it like a shared provider.

We’re going to see how to create a SQLite shared provider, often referred to as a shared service or sometimes a singleton class, in an Ionic 2 Android and iOS application using Angular.

Build An RSS Reader Mobile App With Ionic 2 And Angular

If you’re a long time follower of my blog you’ll remember I wrote an article about creating an RSS reader using Ionic Framework. That tutorial not only used the first version of Ionic Framework, but it now also uses a deprecated Google service, once known as the Google Feed API. Because of the deprecated API, it no longer works.

I still get a lot of people asking me about the creation of RSS readers, so I figured it was time to come up with a new solution. With Ionic 2 being all the rage, it makes sense to explore feeds with this version of the framework.

Here we’ll be building an RSS feed reader for Android and iOS using Ionic 2 and Angular with TypeScript.

Build A Password Manager For iOS And Android Using NativeScript

There are many password managers on the market right now for Android and iOS. I personally use a mobile application called 1Password, but what if you’re the type of person who doesn’t trust these companies with your sensitive passwords? The solution to this would be to build your own password management application, one where you know the algorithms and the logic. I mean, what if the available password managers are using DES encryption when they should be using AES? Best thing to do would be to do the job yourself.

We’re going to see how to develop a password manager for iOS and Android using the NativeScript framework by Progress Software. The application that we build will be completely functional, have a polished UI, and use all the best practices for cipher text and mobile development.
