Learn A11y, Flutter and Mdx

- Web audio APIs include support for features that aren't available by default in the native HTML audio element.
- The operating system includes basic controls
- Custom controls must be accessible with a keyboard, and make sense to a screen reader
- Don't hide the built-in controls until you know that your custom controls are working
- Listening to what VoiceOver reads should inform the a11y information you include
    - VoiceOver says "Elapsed Time" on its own, so we wouldn't want to write it in our code.
- `loadedmetadata` should have the duration to avoid glitches from new audio not being loaded.
- Elements should be labeled with a unique `id`

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.

Create an Accessible Audio Player with the HTML Media Element and React

Web accessibility (also referred to as a11y) is the design and creation of websites that can be used by everyone. Accessibility support is necessary to allow assistive technology to interpret web pages.

React fully supports building accessible websites, often by using standard HTML techniques.

Erin Doyle is an expert in creating accessible React applications and has developed a course that will give you a concrete process for auditing react apps for accessibility. In this course, you will go through different tools and libraries to audit components in a React app.

Fast, easy and reliable testing for anything that runs in a browser.

Auditing React Apps for Accessibility 

MDX has grown rapidly since the first commit two and a half years ago. We'd like to celebrate our accomplishments so far, and talk about what lies ahead. We've got lots of plans.
Learn how MDX increases developer productivity, improves educational content authoring, and even peek behind the curtains to see how MDX works.

MDX is an authorable format that lets you seamlessly use JSX in your markdown documents. You can import components, like interactive charts or notifications, and export metadata. This makes writing long-form content with components a blast.

Flutter allows you to build beautiful native apps on iOS and Android from a single codebase.

In this lesson, we will cover Interfaces and Mixins. Interfaces act as a contract containing properties and methods that a class must define once it “implements” this interface. Mixins are Dart’s way of sharing properties and methods from multiple classes, since by design Dart adopts a single-inheritance model.

Futures represent a computation that does not complete immediately. Where a normal function returns a result, an asynchronous function returns a Future that will eventually contain the result. These are similar to Promises in JavaScript. In this lesson, we will learn how to program asynchronously by writing logic to capture values that are returned at a later time.

Capture and Return Asynchronous Values with Futures in Dart

Streams represent a sequence of asynchronous events. Each event is either a data event, also called an element of the stream, or an error event, which is a notification that something has failed. When a stream has emitted all its events, a single "done" event will notify the listener that the end has been reached. In this lesson, we will learn how we can capture and handle streaming data, working with various Stream classes.

In this lesson we’ll learn how to fetch & then display data from an API over the network in a Flutter application using the http package.

Pub is a package management tool that makes it easy for you to install, use, share Dart libraries, command-line tools and other assets. It comes as part of the Dart SDK, and requires a dependency file called pubspec.yaml.

In this lesson we look at navigating between two pages using the `Navigator`.

Extension methods allow you to add new methods to classes without directly changing its original interface or creating a derived class. We will explore examples of working with this feature by extending some inbuilt types.

Monica Powell, creator of React Ladies, talks through why someone would migrate from Remark to MDX before going into how to do that and what problems you might run into.

Migrating to MDX

Cole Bemis explains how MDX works by taking us though his own journey digging into what MDX does under the hood.

Demystifying MDX

Laurie Barth walks us through MDX v2's syntax by trying to break it. She starts at markdown syntax and takes us through increasingly complex applications of MDX, including passing dynamic props to .mdx files imported into other .mdx files.

Jonathan Bakebwa introduces MDX support for VueJS and NuxtJS while also using Chakra UI Vue for MDX components

MDX and VueJS/NuxtJS

Prince Wilson, MDX contributor, takes us through one aspect of his personal site playground and dives deep into interactive code blocks.

Building a component library is a great way to gain efficiencies in creating accessible React apps and Storybook is a great tool for doing that. Using the accessibility add-on to Storybook you can test your components in isolation for accessibility issues before composing them into an application.

If you can write and test each of these components initially with accessibility in mind then you now have:

* A library of reusable components with accessibility baked in.
* You won’t need to solve the same problems over and over again.
