A Beginner’s Guide to Storybook 7 with React

- 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`

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 

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.

Nuxt.js enables you to easily create layout and navigation by replacing the default App.vue template with your own `app.vue` layout in a `layouts` directory. Then you simply surround your content (the `<nuxt>` instance) with your navigation and/or layout and you're ready to go.

Create Vue.js Layout and Navigation with Nuxt.js

As you create more and more routes, the paths become difficult to manage and concatenate the parts together as just a giant string. Using named routes allows you to reference the route by a simple string then pass in the params as an object. This lesson covers configuring named routes in Nuxt.js in the `nuxt.config.js` and the passing the named route to a `router-link`.

Configure Named Routes in Vue.js and Nuxt.js

The vue-cli allows you to easily start up Vue projects from the command line while Nuxt.js enables a page-based routing system that follows your file structure. Combine these two projects and you'll have a Vue app created from scratch deployed in a matter of minutes.

Build Vue.js Apps with the Vue-CLI and Nuxt.js

Sometimes the `pages/` directory structure doesn't meet your needs, so you'll need to customize your routes manually. Using the nuxt config and "hidden pages" you can map routes to view components without getting in the way of the default pages routing.

Add Custom Routes for Hidden Pages with Vue.js and Nuxt.js

Nuxt.js allows you to return a `Promise` from your `data` function so that you can asynchronously resolve data before displaying the page. This allows the server to fetch the data and render the page once it's ready.

Preload Data using Promises with Vue.js and Nuxt.js

URLs often reflect some bit of data that the page should load. This lesson walks you through adding a custom URL Param to the router then forwarding that Param to load data onto the page.

Load Data from URL Params in Vue.js and Nuxt.js

In this video you'll learn how to deploy a static Nuxt site to AWS's global edge CDN in less than two minutes. We'll start from scratch, creating a new Nuxt site using npx and walk through the build configuration to set up the deployment target for Jamstack / static site hosting. From there, we'll initialize a new Amplify project using the Amplify CLI and walk through the settings to configure the proper build command for Amplify hosting. Finally, we'll deploy and view the live site. Once we're finished, we'll delete the project and the hosting service.

Deploying a Nuxt Site to AWS with the Amplify CLI

In this video you'll learn how to use Amplify hosting to deploy a Nuxt site from a Git repository. We'll begin by walking through the steps of creating the deployment and configuring the correct build settings to enable a static build. Once the site is deployed, we'll view the live site hosted on AWS.

We can add accessibility testing to our `jest` unit tests with `jest-axe` which gives us:

* An easy way to automate accessibility auditing.
* The flexibility to audit at any level of our code, as low as an element and as high as a component representing an entire page of our app.
* A safety net for any accessibility regressions.

Here we'll see how to use `jest-axe` with `ReactDOM` to render components for `jest-axe` to audit for accessibility.

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

“a11y” stands for “accessibility.” It is a numeronym, with 11 representing the count of letters between the letter a and the letter y.

Accessibility is broken down into 4 categories of disability: visual, cognitive, auditory, motor. 

Regardless of the category of disability, accessibilities aim in web development is to make applications and websites usable for everyone.

We can leverage GitHub Actions to automate the running of all of our accessibility auditing tools as part of a Continuous Integration (CI) workflow. 

Auditing tools will only catch a percentage of potential accessibility issues, it is no replacement for manual testing.  But being able to automate the auditing will add efficiencies to our testing and provide an early warning system that can be run much more frequently than it’s practical to perform manual testing.  Additionally, we can use our CI suite as a safety net to prevent code changes that break accessibility from being able to be merged.

Automate Accessibility Audits with GitHub Actions

You’ve probably heard of Lighthouse before as it comes bundled with Chrome DevTools for performing a number of audits on things such as performance, SEO, best practices as well as accessibility. 

We can also use Lighthouse locally on our machines to test our application's rendered pages for accessibility issues before committing changes by using the Lighthouse CI CLI.

In this lesson we are going to create an `AudioPlayer` component that takes two props `src` and `transcript`, where it returns the audio element and renders the transcript, and we write some pseudo-code for the audio player to reference.

**Think about**: What do we get for free with common HTML elements?

Setup Native Audio and Plan our Audio Player Code

We Introduce [MDN Media docs](https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement) and all the APIs. 

In this lesson, we added the `useRef` and created an `audioRef` in our components. We also added the `ref` to the audio element to control it outside of the audio element. We use the `useState` hook, and we created an `isPlaying` state. And finally, we added a `button` that dynamically renders the text as pause and play depending on the `isPlaying` state. On click of that button, we toggle the `isPlaying` state, and depending on that state, we either pause or play it.


Creating a Toggle for Playing and Pausing the Audio

Bootstrap is an incredibly popular CSS framework designed to make your website look great on mobile and desktop.

By the end of this course, you'll be familiar with many of the popular classes and components that Bootstrap uses to apply in your own projects.

For each feature you build in the course, you'll get a sense for what the relevant classes do for those components and links to documentation for further exploration.

For the course demo application, we will analyze the landing pages of Microsoft and Apple to identify common components that are implemented. When these are identified, you'll implement these components yourself with Bootstrap.

You'll build several common UI elements such as a nav bar, a carousel of images, Cards, and Forms.

Through building these components, you'll understand what is behind the different classes Bootstrap gives you and get familiar with how it exposes flex and grid layout for you.

Cascading Style Sheets bring order and beauty to our applications.
