Learn Edge, Reflux and Xstream

Coding for accessibility? You should get familiar with the accessibility tree, a structure produced by platform Accessibility APIs running parallel to the DOM, which exposes accessibility information to assistive technologies such as screen readers. There are multiple tools for visualizing this tree; in this lesson we'll look at Chrome and Microsoft Edge. For more on Accessibility APIs, refer to this [amazing article by Leonie Watson](https://www.smashingmagazine.com/2015/03/web-accessibility-with-accessibility-api/). For a how-to on setting up the Chrome Accessibility Inspector, visit [bit.ly/chrome-a11y](http://bit.ly/chrome-a11y).

What is the Accessibility Tree?

Cycle.js is a framework where your app is described as a simple function taking an event stream as input and outputting an event stream.

This lesson is the first in an introduction to Cycle.js. We will see how to build from scratch a toy version of Cycle.js. See how to use RxJS to create simple web apps, and how to separate logic from effects.

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.

Reflux uses Actions to tell the Stores when to update. We will wire Actions and Stores together to create a simple updatable age field React component.

Reflux - Creating Your First Action in React

Reflux makes connecting to a store extremely simple. Let's refactor a React component so that the data now comes from a Reflux store and allows the data store to trigger future updates.

Reflux actions don't need to be used within React components, you can trigger them from anywhere. John demonstrates this concept by extracting the actions away and then invoking them through jquery.

Reflux - Manually Triggering Actions

Neither React nor Reflux come with a built-in library for loading data. Many people use jQuery, but this jQuery is heavy for the task. In this lesson, John shows you how to easily load in some data using Superagent and walks you through the process of displaying and formatting the data in your component.

ASP.NET is an open source web framework for building modern web apps and services with .NET. ASP.NET creates websites based on HTML5, CSS, and JavaScript that are simple, fast, and can scale to millions of users.

If you want to improve a REST API beyond GET/POST&PUT and DELETE the next step would be adding the push functionality to send new data into your web applications. With ASP.NET Core and SignalR you can add this functionality with ease and keep your application up to date without letting the clients reloading their page manually.
