Learn Android, Angularjs and Aria

A large number of people are unable to use the web effectively due to an impairment or disability.

As developers there are several tools and techniques we can use to make our web applications accessible, ensuring a great user experience that includes everyone.

We all agree that Accessibility is important. However, it’s a broad landscape and can be overwhelming figuring out where to start!

Erin Doyle is an expert in creating accessible React applications and has developed a course that will give you a concrete process for testing, refactoring, and building your applications with accessibility in mind.

After this course, you'll have a jump start on auditing and fixing accessibility issues in your applications and gain a better understanding of your target users and how to approach your web app design from their perspectives.


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.

Develop Accessible Web Apps with React

Skeleton screens show users that content is loading, offering a vague preview of how content will look once it fully loads.

CSS Animations are crucial for the perceived performance purposes since it shows for the user the content is loading by using animations as feedback for whoever is accessing the page. 

Follow the steps in this course and you will learn how to create a beautiful and pleasant Skeleton Loader for your web app using CSS animations, focusing on Web Accessibility and Web Semantic.

WAI-ARIA, the Accessible Rich Internet Applications Suite, defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies.

Creating Accessible Skeleton Loader Animation from Scratch with HTML and CSS

One of the hardest things about writing non-trivial applications is managing state. In our attempt to effectively manage state, we introduce additional complexity by trying to control application flow and the amount of code volume that comes from all of this. Redux gives us the ability to address state management and communication in astonishingly simple semantics that can be explained in just a couple minutes. The beauty of Redux is that it is not only a library but a pattern that works very will within Angular 1.x applications. In this series, we are going to learn how to integrate redux (the pattern) into Eggly from scratch and then introduce **ng-redux** and add in **Redux DevTools** at the end for fun.

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.

Build Angular 1.x Apps with Redux

Implementing modern component-based architecture in your new or existing Angular 1.x web application is a breath of fresh air.

In this course, you are going to take a close look at Eggly, an Angular 1.x application for organizing bookmarks, and build it using modern patterns and practices, inspired by Angular 2's recommended architecture.

You will learn how to leverage ES6 in your Angular 1 applications through Babel, and fully understand the core patterns that are used in a composed modular web application. 

This course will teach you how to leverage your existing knowledge of Angular, while preparing your mind (and applications!) for the future.

If you are interested, there is a [companion guide](http://www.angular2patterns.com/) that digs deeper into the patterns found in this course and Angular 2.

Using Angular 2 Patterns in Angular 1.x Apps

Accessibility (or a11y) is an important but often neglected in the world of web development. Many developers find themselves coding user interfaces without any knowledge of keyboard or screen reader requirements. 

The fact is that accessibility doesn't happen by accident. Often it is seen as too hard or time consuming. This doesn't have to be the case. By following a handful of high-value patterns and practices, we can open our web apps to humans that otherwise wouldn't be able to interact with them at all.

This course will introduce you to accessibility through hands-on, technical examples that are way more effective than reading 10-year-old static web content.

How much work would it take for you to move all of your directives and their templates to several different new directories? You'd have to update the templateUrl, script tags, etc., etc. With webpack, this can be trivial. For example, you don't need to worry about loading your templates in the $templateCache ever again. Webpack will help you modularize your css and tests. All of these things and more in this series so you can start using webpack with Angular today.

AngularJS and Webpack for Modular Applications

Angular Material is an Angular-native, UI component framework from Google. It is a reference implementation of Google's Material Design and provides >30 UI components and services essential for mobile and desktop AngularJS applications.

In this course, we will quickly build a real-work application Angular UI application, take a tour of Angular Material, and learn how ngMaterial can be used in your projects.

Introduction to AngularJS Material

Open source framework for building truly native mobile apps with Angular, TypeScript or JavaScript.

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.

Use an Android library in NativeScript for Angular using Java apis

angular-formly provides a very simple API to dynamically change properties of your field (like disabled, hidden, and required) using the powerful expressionProperties property on your field.

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

angular-formly allows you to default the values of fields for your angular forms using the `defaultValue` property. To default the value of a field, you can either initialize the `model` with the default value, or use this `defaultValue` property on the field configuration.

angular-formly: Default Values

AngularJS validation can be tough, but angular-formly makes it extremely simple with a single validation API that enables basic and advanced field validation. You can specify a string expression, function that returns true/false, or a function that returns a promise which is resolved/rejected.

angular-formly: Custom Validation

The Angular Material Layout API wraps the flexbox CSS features with an amazingly easy, powerful HTML markup API. The Layout API hides the complexities of the CSS, is intuitive to use, and eliminates the need for developers to become flexbox experts to implement modern page layouts. 

In this lesson we will learn how to use the Angular Material Container components and the Layout API to implement the layouts specified in design wireframe.

Angular Material: Containers with the Layout API

Themes convey meaning through color, tones, and contrasts. And the theme color palettes, alphas, and shadows deliver a consistent tone to your application and a unified feel for all Angular Material UI components. Theming allows developers to change the intention and meaning of the application by changing the colors and shadows. 

Accessibility is a huge - often overlooked - feature in modern web applications. Angular Material components all implement ARIA features whenever possible. And for usage scenarios where the ARIA attributes are not explicitly provided and cannot be inferred, then Angular Material will provide details console warnings alerting the developer.

Let’s use the Angular Material Theming service to change the background, primary, accent, and warning colors used within the entire application. These will be configured at startup using the $mdThemeProvider.  

Let’s also resolve the two ARIA warnings shown in console. These originate from icon buttons where the ARIA label cannot be inferred. So let’s add a static aria-label and a dynamic, interpolated aria-label to those buttons.

Angular Material: Theming and ARIA

In Angular, we want to keep our controllers lightweight and specific to the view that it is controlling. To accomplish this, we are going to refactor our categories collection into a CategoriesModel. A recurring theme in Angular 2 is that everything is "just a class". When we create our controllers and services in an Angular 2 style, they are also "just a class". We will see this in action as we convert our controller almost verbatim into a service.

Refactor Angular Controller Logic to Services

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

Directives might just be the **killer** feature of AngularJS. Directives allow us to extend the grammar of the web through reusable HTML elements, attributes, and classes.

The ui-router library for AngularJS provides several options for navigating between states in your application. You can navigate via the browser's URL bar, programatically with `$state.go`, and with the ui-sref directive on your HTML elements.

ui-router: Activating States

The first step to **any** AngularJS project, is actually adding AngularJS to the page. This lesson will show you adding the Angular script, initializing the app with ng-app, and simple two way binding with ng-model. This is a *beginner* level lesson.

First Step: Adding Angular to the HTML Page

Use AngularJS $rootScope within a directive to detect route change errors and display it to the user.
