CouchDB and Ionic

Getting Familiar with CouchDB and Futon

Over the past few weeks, I’ve been working on writing a series of tutorials on how to use CouchDB and PouchDB in Ionic 2. This video tutorial is sort of an aside to that – I wanted to create a demonstration of creating CouchDB databases and playing around with the data a bit, just to […]

Security in Ionic

[VIDEO] Basic Security for Ionic & Cordova Applications

I recently wrote an article with some basic security advice for Ionic and Cordova applications, but I thought it would be worthwhile discussing those concepts in a little more depth. In this video tutorial, I talk through the concepts that I brought up in the security article. Here’s the video:Follow @joshuamorony Video Notes You don’t […]

Live Coding Drag Directive

“Live” Coding a Custom Directive in Ionic 2

I’m trying something a little bit different with this video. Most of the videos I create aren’t scripted, but I do have a general plan of attack before recording and, more or less, know what I am going to say and do. I’ve created multiple custom components and directives in the past, and have done […]

Sending Post Request in Ionic 2

How to Send Data with POST Requests in Ionic 2

In the past, we have covered how to make a simple GET request to load data from a server, and for the most part, making a POST request is pretty much the same. There are a few key differences, though, including the fact that a POST request also includes a body, and there’s also a […]

Listening for Host Events

Listening to Events on a Host Element in Ionic 2

When creating a custom directive (and in other circumstances) you may be interested in listening for events that are happening on the host element. Let’s say for example that I created a custom directive that I wanted to attach to the <ion-content> component, like this: The host element, which is <ion-content> in this example, may […]

RxJS Observables

An Introduction to Observables for Ionic 2

Observables are one of those new tricky things you will almost certainly run into at some point when building an application with Ionic 2. They can seem a little weird and overwhelming at first, and you might wonder “why can’t we just stick to promises?“, but they are quite beautifully implemented. At a basic level, […]

List Reorder in Ionic 2

Reordering a List in Ionic 2

It’s super easy to create lists in Ionic 2, and it’s also super easy to allow a user to reorder them. With the addition of a simple attribute, you can turn your normal <ion-list> into a reorderable one. In this video tutorial, I walk through exactly how to create a reorderable list in Ionic 2. […]

Phaser

Anatomy of a Phaser Project

If you’re new to building HTML5 games with Phaser, like with any new language or framework, it can be quite a hurdle just to grasp the structure and the basic idea of how it all works. In this video tutorial, I will walk through the general structure of a Phaser project and the important parts […]

Using Gestures & Uncommon Event Bindings in Ionic 2

In this video tutorial, we cover how to create event bindings other than the usual (click) event binding in Ionic 2. We will cover how to use gestures like press, swipe, pan, pinch, and rotate, as well as some more uncommon events like keydown and keydown.space. Here’s the video: Video Notes Event bindings like (click) […]

Structural Directives in Ionic 2

An Introduction to Structural Directives: *ngIf & *ngFor

In this video tutorial, we cover the concept of using structural directives like *ngIf, *ngFor, and *ngSwitchCase in Ionic 2. Structural directives are an Angular concept, but we will be discussing them in the context of an Ionic application. In short, a structural directive allows us to add or remove content to our applications based […]

NgModule in Ionic 2

An Introduction to NgModule for Ionic 2

We all use it, it’s a critical part of our applications structure, but I think a lot of people are confused by what exactly it is and what it does. I’m talking about the @NgModule in the app.module.ts file in an Ionic 2 application. In short, using modules allows us to organise our application into […]

Adding libraries in Ionic 2

How to Install 3rd Party Libraries in Ionic 2

Ionic 2 allows you to do a wide range of things right out of the box, but there is likely going to come a time where you need to install some 3rd party library to add additional functionality into your applications. You may want to add Google Maps, add a charting library, add support for […]

Providers in Ionic 2

How, Why, and When to Use Providers in Ionic 2

Providers allow you to create a self-contained service that provides some kind of functionality to your application. The role of a provider might include things like fetching data from a server, performing operations on data, sharing data, providing a set of complicated mathematical operations, and so on. In general, we use providers to do the […]

Semantic CSS Styling

Using Semantic CSS Styling in Ionic 2

When creating styles with CSS it is common to attach .classes and #ids to DOM elements so that we can reference them in the CSS file. We can also just use element names directly to apply styles, and there are many more selectors we can use. In this video tutorial, I walk through a semantic […]

Cordova Plugins in Ionic 2

An Explanation of Cordova Plugins for Ionic 2

One of the downsides of creating a web based mobile application is that you don’t have access to all of the device functionality that a native application does, and you can’t submit your application to app stores. Cordova solves this problem. Cordova is commonly used to wrap a web-based mobile application inside of a native […]

Google Maps in Ionic 2

Getting Started with Google Maps in Ionic 2

Google Maps is one of the most used features in a mobile application, and my tutorials on Google Maps have consistently been the most popular on the site. My previous video on using Google Maps in Ionic 2 was created a long time ago, and is now outdated. So, I wanted to put together another […]

Pipes in Ionic 2

Custom Pipes in Ionic 2

Pipes are a convenient way to modify data before displaying it to users in templates. You can think of them as a pipe in a literal sense. You can push data through this pipe, something happens to it inside of the pipe, and when the data comes out the other end it looks different – […]

Custom Components in Ionic 2

Custom Components in Ionic 2

The Ionic 2 library provides a wide range of default components – likes lists, segments, and cards – that can easily be added to your applications, but sometimes it is useful to build your own custom components. Building your own custom component isn’t all that different from building a normal page in Ionic 2 (they […]

JSON in Ionic 2

Loading Remote JSON Data with HTTP in Ionic 2

Often, we will need to load some data into our applications. One common way to do this is to load a JSON (Javascript Object Notation) string from some source, and convert that into a Javascript Object that we can view and manipulate in our application. In this video tutorial, I walk through how to use […]

Saving Data in Ionic 2

A Simple Guide to Saving Data in Ionic 2

Many applications require the ability to save data in some manner so that a user can perform some actions in the application, close the application, and have the application remember the user’s input from the last time they opened the application. By default, anything you do within your application is just going to be lost […]

Sharing Data Between Pages in Ionic 2

Passing Data Between Pages in Ionic 2

When building an application that has more than a few pages, there’s a good chance that those pages won’t be working in isolation. You may want to send data from one page to the next, send data back to the last page, or even access some data from one page in an entirely different area […]
