Make A Gallery-Like Image Grid Using Ionic Framework

March 12, 2015 Nic Raboy

I recently started making an application with Ionic Framework that made heavy use of images both remotely and locally. During this time, my goal was to present the images in a grid that looks good for all device sizes and orientations.

One might think this would be an easy task because Ionic offers both grids and a responsive class, however, trivial was far from the case. Instead I had to go to my programming roots and create some display logic when looping through my arrays of images. The following guide will show exactly what I had to do.

Create A Random Nonce String Using JavaScript

March 10, 2015 Nic Raboy

Have you ever needed to come up with a random string of characters say for a password? Maybe you’re looking for a random string of characters for an oauth 1.0 nonce. Maybe you’re in a job interview and you’re asked to generate a random alpha numeric string.

Whatever the case, we’re going to look at generating a random string of characters of any given length using JavaScript.

Parse A JSON File With Java

March 7, 2015 Nic Raboy

Recently I was tasked with reading a JavaScript Object Notation (JSON) file using Java. In my project, the JSON file contained properties information to be used inside the application.

There are many libraries available for reading or parsing JSON data in Java, but in particular we are going to be using the library found on json.org.

Check And Update Outdated NPM Packages

March 4, 2015 Nic Raboy

The Node Package Manager (NPM), is becoming a major go-to resource for all development software and libraries. It is easy to use and covers a lot of ground.

If you’re anything like me you’re going to have more than twenty global packages installed on your machine through NPM, but how do you go about tracking whether or not any of them have become outdated?

Create A Todo List Mobile App Using Ionic Framework

March 1, 2015 Nic Raboy

Since writing my two tutorials regarding using SQLite in Ionic Framework and shipping an app with a pre-populated database, I’ve received many requests for a tutorial for making a full blown app. I listen to my readers, so I figured what better way to show such an example, than to create a todo-list type application.

In this tutorial, I hope to accomplish the following:

• Shipping a pre-populated / pre-filled SQLite database
• Access the SQLite database and perform operations based on user input
• Include a WebSQL alternative for testing via a web browser
• Navigate between views using the AngularJS UI-Router
• Remove todo items from your list using swipe gestures

All items that I wish to accomplish have seen their own tutorials. If you’re familiar with the Marvel comic book movies, you’ll know that every hero has their own story, then they meet up for the bigger picture in an Avengers movie. Think of this tutorial like that.

Get Available Free Disk Space Using Apache Cordova

February 27, 2015 Nic Raboy

It was brought to my attention that the File plugin for Apache Cordova has no documented methods for finding the available disk space on a device.

This does not mean that you cannot figure out how much space is available on your users device because you can make use of Apache Cordova’s nifty cordova.exec function.

Reverse Words In A String Using JavaScript

February 25, 2015 Nic Raboy

Back on the topic of possible programming interview questions, you may at some time in your career be asked to reverse words in a string. This is a much simpler problem and may be more likely to appear on a technical phone screening.

In it’s simplest form, you would assume all space separated string collections to be words. To clarify, it doesn’t matter if you’re looking at a true word or just some jumbled text separated by a space character.
