Learn Ionic, Redux-observable and Xstream

Handling async actions that affect your application’s state sounds like a tall order, but Redux makes it possible — and a win-win for you and your app’s users.

In this course, we will begin with nothing more than an empty directory and a text editor. Through small, focused lessons, we’ll learn how to set up a React project that uses Redux for state management and redux-observable for asynchronous actions. We’ll see how ‘epics’ are registered and how they each receive a ‘stream’ of actions from the store.

With an understanding of how things work, we’ll move onto solving common problems like: 
- Ajax cancellation
- creating sequences of async actions
- enabling code reuse through higher-order Observables 
- and much more.

RxJS 5-based middleware for Redux. Compose and cancel async actions to create side effects and more.

Theming Ionic applications is a topic that is often left undiscussed. Ionic has a robust API to theme your application so you don't have to settle with the default styles.

This course will show you how Ionic’s theming system works so that your application can have its unique look. It will explore the built-in utilities, which you can leverage directly.

You'll be introduced to the built-in CSS utilities that Ionic provides, Ionics grid system, and Ionic configuration settings to create a custom look and feel to your App.

Ionic is the beautiful, free and open source mobile SDK for developing native and progressive web apps with ease.

***Note: RxJS imports have changed since the publication of this course. Operators now must be passed into `.pipe` to be applied to an observable.***

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.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Up and Running with redux-observable

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

Ionic allows you to build cross platform native applications using Angular. In this course we will convert the Eggly AngularJS application into an Ionic mobile application.

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

Building an Angular 1.x Ionic Application

Welcome to the *Ionic Quickstart* series where you will learn how to get started with Ionic from the ground up. We will begin with how to install the required dependencies such as Node.js, Android SDKs and even GenyMotion to installing and running Ionic. By the time you finish, you will know how to create, edit and run an Ionic application. If you are on Windows or Mac and not sure where to start with hybrid mobile development, this is a great place to start!

Creating cross-platform web-based applications with Ionic 4 and React is easy thanks to the Stencil compiler and `create-react-app`.

In this video, we look at how to use create-react-app and @ionic/react to make an Ionic 4 + React application

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Creating cross-platform web-based applications with Ionic 4 and Vue is easy thanks to the Stencil compiler and the Vue.js CLI.

We look at how to combine these together to use Ionic 4 components within our Vue.js applications.

In this lesson, we install the Android Software Development Kit (SDK) and the necessary Android API (Application Interface). This is the code base that allows us to run the Android platform on our PC. We also add a couple environment variables and update our PATH environment variable.

In this lesson we’ll learn exactly what’s needed to incorporate redux-observable into an existing React/Redux application. We’ll learn what ‘Epics’ are, and how they receive a stream of actions and return a stream of actions. In-between is where we get to apply side-effects, call out to external services etc etc. In this lesson we’ll demonstrate the ‘async’ nature of epics by responding to an action with another, delay action.

Add redux-observable to an existing Redux project

Redux is a predictable state container for JavaScript apps.
It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test.

In this lesson we’ll learn how to perform an Ajax request to an external API in response to an action in the redux store. We’ll see how, within the epic, we get access to actions after any reducers have been executed and how we can convert that incoming action into a resulting one that will save the data received into the redux store.

Use redux-observable for simple Ajax requests

With redux-observable, we have the power of RxJS at our disposal - this means tasks that would otherwise be complicated and imperative, become simple and declarative. In this lesson we’ll respond to an action by queuing up 2 separate Ajax requests that will execute sequentially. Then we’ll group the results from both into an array and produce a single action from our epic that will save the data into the redux store

Create a queue of Ajax requests with redux-observable and group the results.

When accepting user input and converting it into a request that talks to the outside world, we can often end up in a situation where responses are no longer relevant. This is a common case in type-ahead style input fields - we would only want to call an external search API after the user has stopped typing for a short amount of time. In this lesson we’ll see how we can begin to combine RxJS operators to solve such problems. 

Debounce user input to avoid repeated Ajax requests

Any application that uses external services such as APIs should be able to handle errors gracefully. Often this requires no more that displaying a message to the user and ensuring the application continues to function. In this lesson we’ll look at how we can convert an error from the network into an action that is dispatched into the Redux store, allowing us to show an error message to the user and prevent the application from crashing.
