Building native mobile applications has traditionally been a completely foreign work flow than web development. Recently frameworks, such as Ionic and React Native, have been come out to create a similar web development workflow in a native environment. 

Ionic 2 builds on top of Angular to offer a complete framework for building mobile apps using HTML, CSS, and Javascript that target native mobile and the browser. We’ll work with the RandomUser API to create an employee directory that will let us view user details, update that information, and pass the data back and forth with Ionic 2 routing.

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

Building apps with Ionic 2

Vim is a classic text editor that saw its first incarnation in 1976. Used around the world across most platforms, the ability to drop into a computer, open a command prompt and type `vim` is a simple yet powerful concept.

In this course we will take a tour of Vim, and learn the essentials you need to know to start being productive with this powerful text editor. We will learn about basic movement through a file in Vim without a mouse, loading and saving files, commanding the Vim editor, and get started customizing Vim to suit your needs.

Vim is a highly configurable text editor built to make creating and changing any kind of text very efficient. It is included as "vi" with most UNIX systems and with Apple OS X.

Learn to Use VIM

The Vim editor is a text editor that lives inside of your terminal. Learn how to start Vim, and more importantly how to exit out of the editor! 

Intro to Vim

Learn how to efficiently move around Vim and stop reaching for your mouse

Moving around in Vim

Vim likes to keep you in normal mode at all times. But this can be difficult when trying to delete or change some text in a file. Thankfully Vim has build commands to make this a breeze

Vim's built-in commands

Gesture driven lists are a great way to take a simple UI element and make it fun. We'll look at how we can make swipe-able list items to reveal additional functionality, as well as being able to drag and reorder list items.

In this lesson we will walk through how to break out code into it's own provider using the CLI. Ionic’s CLI provides a generate command that will quickly help create common components, pipes, providers, and much more. To see what kind of generators are available, run `ionic g --list` in your terminal.

One of Vim's most unique features are it's different modes. Learn how to use these modes and speed up your editing

Vim's different modes

We've learned how to add text in Vim using insert mode, now what about saving that file? We'll go over how to use Vim's write command. 

Saving Files in Vim

The simplest way to display data in an app is with a simple listview. This list will go over how items work and how to place certain elements in ion-items position slots.

Ionic offers a few different layouts, including a side menu-based one. We’ll setup a simple side menu layout from scratch and see how it behaves on different devices. For instance, if you're users are on an Android device, the side menu (and really, the whole app) will look and behave like a native Android app. As the user swipes from the side, the menu will overlay the main content. For iOS, the menu will not move, but the app's main content will instead.

We've gone over some of the basic Vim key commands, but what else can you do with them? We'll go over how you can compose them and to create more powerful commands

Combining Vim commands 

Ionic’s NavController offers an extensive API that allows you to manipulate your apps history, create history from nothing, and programmatically navigate back. NavController has an extensive API with many methods and lifecycle hooks that developers can use. Be sure to check out the [documentation](http://ionicframework.com/docs/api/navigation/NavController/)

Sometimes you just need to copy some code from one file to another. Vim allows you to do this, in a quick and efficient way. 

Copy and Paste inside of Vim

Vim's defaults leave the editor in a pretty minimal state. Let's look at some of options we can configure to make Vim feel more like a traditional editor

Configure VIM

Now that you know how to enable features in Vim, let's store all of them in one place so we don't need to constantly set them all the time.

The Vim Config file

Vim has the ability to extend its functionality through plugins that can be installed either manually or through plugin managers. We'll setup the [vim-plug](https://github.com/junegunn/vim-plug) manager to install plugins for our `.vimrc` 

Introduction to Vim Plugins

A common UI pattern in mobile apps is to be able to “pull” down on a list and fetch more data, or scroll and load more. This kind of pattern is built into Ionic with the ionRefresher component and ionInfiniteScroll component.


[Infinite Scroll](http://ionicframework.com/docs/2.3.0/api/components/infinite-scroll/InfiniteScroll/) and [Refresher](http://ionicframework.com/docs/2.3.0/api/components/refresher/Refresher/) can be heavily customized as well. Both components allow you to change what is shown as the user begins to perform their action. This allows for a much more customized experience!

Lazy Load Data with Ionic 2

Ionic 2 has it’s own navigation system that that makes it straightforward to link components. We’ll look at how to take data from one template and pass it to another using Ionic NavController. 

Instead of thinking in terms of URLs and hrefs, NavController allows devs to think in terms of a component stack. To navigate forward to a new view, a developer pushes a new component on to the navigation stack. To go back, the component is popped from the stack. This push/pop metaphor is borrowed from traditional native development and allows for a more flexible navigation paradigm.  

Navigate Between Mobile Screens  with the Ionic 2 NavController

Ionic’s CSS and JS can detect what platform a user is on, and adjust to make sure you’re getting the correct interface. To preview this locally, you can use the CLI’s `--lab` flag to see what your app will look like before it’s even deployed to a device.

Ionic provides a common API for displaying many overlay components, like Alerts, ActionSheet, Modals, and Popovers. We'll look at a few of the APIs and see how to interact with them. To learn more about these different APIs, be sure the view the documentation on them:

- [ModalController](http://ionicframework.com/docs/2.3.0/api/components/modal/ModalController/)
- [ViewController](http://ionicframework.com/docs/2.3.0/api/navigation/ViewController/)
- [AlertController](http://ionicframework.com/docs/2.3.0/api/components/alert/AlertController/)
