Learn Nativescript, React-router and React-storybook

NativeScript has the ability to write Objective C, Swift and Java apis directly from JavaScript and TypeScript. 

In this course, we will learn how to code directly against these native api’s with NativeScript for Angular. Many libraries are written and published in these languages. With NativeScript you are no longer limited to just JavaScript based libs, but have direct access to these api’s right from JavaScript/TypeScript. Let’s look at how to include these native libraries internally to your project as well as build public plugins to share with the community. 

We will cover some considerations with Objective C and Swift based libraries as well as Java/Android libraries. You can think of CocoaPod, Gradle, and Android Arsenal like npm for native libs. iOS libraries can be found via CocoaPods, Android libraries can be found via Gradle or Android Arsenal. 

Let’s also cover how to write custom view components based on native libs since there are considerations for both iOS and Android. Lastly we will learn how to best handle cases where a plugin/library only supports 1 platform.

In this course, we will learn how to use the core layouts for NativeScript apps. We will start with the basic principles of NativeScript layouts using XML. This course will use the app templates provided from the NativeScript framework and installed using [the NativeScript CLI](https://egghead.io/lessons/angular-1-x-set-up-a-native-app-project-with-the-nativescript-cli).

We will cover the following layouts: `StackLayout`, `WrapLayout`, `GridLayout`, `DockLayout`, `AbsoluteLayout` and `FlexboxLayout`. Understanding the concepts and usage of UI layouts in NativeScript is key for a great app.

React Router v4 takes an entirely new approach to routing and handling URLs in your React applications. It fully embraces the concept of declarative programming and a component based development process. In practice, this turns out to be very nice and gives you a routing solution that is less configuration heavy than many previous solutions.

In this course, you will learn about the basics of React Router v4 to help you get started. We will look at the core components that React Router supplies and how they interact together to create a robust routing solution for your React applications.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

In this course, we will learn how to work with NativeScript for Angular. We will start with the basic fundamentals of getting setup to run our app in the iOS Simulator in addition to an Android emulator using GenyMotion (https://www.genymotion.com/). Understand how to build your native mobile views with NativeScript XML and how to style them with CSS. Using the NativeScript for Angular starter template provides a nice setup out of the box including the core theme which provides handy CSS classes to work with speeding up view building. For page navigation, we will learn how to use the Angular Router to configure a flexible routing setup for our app. The ListView component is a powerful and highly performant native control for handling your lists powered by the UITableView on iOS and native ListView widget on Android. We’ll highlight how you can use RxJS Observables with our native views. Let's also take a look at integrating npm plugins to enrich the UI component library. Lastly, a round up of styling how-to's including integrating SASS for custom app theme creation as well as creating a live app theme switcher.

This Angular course assumes a solid understanding of the fundamentals.
We have Intermediary Angular courses including topics on [Dependency Injection](https://egghead.io/courses/angular-dependency-injection-di-explained), [Components, Directives](https://egghead.io/courses/building-angular-components), [Forms](https://egghead.io/courses/intro-to-angular-forms), [Router](https://egghead.io/courses/intro-to-angular-router), and [Animating Web Apps](https://egghead.io/courses/animate-angular-web-applications)

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.

React Router is the defacto router for any React application and it allows us to extract the state of our application from the browser's address bar.

In this course we'll explore the core features of React Router in common examples.  From routing with individual components to more complex routing consisting of multiple components, query-strings, route parameters,  and redirects.  

Getting Started with React Router v3

The default core theme comes preinstalled and ready to go with every new project. Learn how to use some of the many helpful utility classes that are provided like common `btn` classes for Buttons, `h1`, `h2`, etc. Label classes and convenient `p-10` or `m-10` (shorthand margin/padding) classes ranging from 0 - 30. You can learn all about the rich options you get here: http://docs.nativescript.org/ui/theme

React Router v4 doesn’t require a lot of configuration to run. The core examples will run out of the box with Create React App. In this lesson, you will create an application and get React Router v4 up and running.

_**note**: in this video `react-router-dom` is installed with the `--save-dev` flag. This is **not required and may cause issues if used**. Simply install it with `npm install react-router-dom` and it will function as expected._

Run the React Router v4 Examples with Create React App

React Router 4 has several routers built in for different purposes. The primary one you will use for building web applications is the BrowserRouter. In this lesson you will import the BrowserRouter and create some basic Route components.

We will learn how to add an Android library to our project and translate it’s Java api to NativeScript. For this lesson, we will look at [Filestack’s Android SDK](https://github.com/filestack/filepicker-android) built with Gradle. Specifically, we will cover how to immediately start working with the library even when a [NativeScript](/q/nativescript) plugin does not exist for it.

Java has been around a long time and when it comes to Android, you will encounter some structures that may throw you for a loop on how to code against with NativeScript. Let’s examine a few common Java/Android api constructs you may encounter and how to translate them to NativeScript. Learn how to get references to local files in your app using the ‘file-system’ module as well as how to take advantage of NativeScript’s Observable class to send notification events from one class to another. Lastly, look at considerations with Angular’s NgZone when handling your native libraries data events to update component view bindings.

Translate common Java/Android APIs into NativeScript for Angular Android apps

Objective C is a very interesting programming language which offers a lot of power as well as interesting paradigms. Let’s look at some Objective C api’s and how they translate to NativeScript. In particular, let’s learn how to wire up iOS delegates using [Filestack's FSPickerDelegate](https://github.com/filestack/FSPicker#fspickerdelegate) as an example. We will also look at handling WeakRef’s and iterating an NSArray.

Use Objective C Delegates in NativeScript for Angular iOS apps

One of the exciting benefits you have with NativeScript is the ability to write native code (Java and Objective C) directly in JavaScript/TypeScript allowing you to create a consistent high level api over top of both underlying iOS Objective C/Swift and Android Java apis. In this lesson, we will look at how to design a consistent api that taps into the appropriate native api’s on the target platforms using underlying native libraries.

Develop a consistent plugin api across your Android and iOS NativeScript app

To prepare your development environment to code against native apis such as Objective C, Swift and Java, let's learn how to [install tns-platform-declarations](https://www.npmjs.com/package/tns-platform-declarations) to provide rich intellisense support for all the native iOS and Android api’s. This lesson will cover how to modify your tsconfig.json and references.d.ts properly to ensure working with native api’s is smooth and as helpful as possible.

Prepare for native iOS and Android api intellisense with NativeScript

We will install the NativeScript CLI and use it to generate a project.


Set up a native mobile app using the NativeScript CLI

We can run our app in the iOS Simulator using the `tns` command line utilities. Also learn how to target specific simulator devices and versions. You must have a Mac to develop apps for iOS. Ensure you have XCode installed via the Mac App Store, and ensure you have opened it at least once to agree to the terms and install the additional components it may prompt about.
