Learn Edge, Gulp and Radium

In this series we will take a look at Gulp. Gulp is a task runner. It is the commander of our army of helper robots that take critical, yet totally mundane, tasks and perform them hundreds of times per day so we don't have to. When we sit down to work, we want to enter a single command, and then spend the rest of our day writing code, testing, and basically not thinking about how it is all glued together in the background.

Automation is critical to any project of significant size. We will start with the Eggly Bookmarks application, and develop proper build automation that will include **production ready** tools that you can start using in your applications today!

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.

Angular Automation with Gulp

In this lesson, we are going to learn how to create a config file to store common values so that we can reuse them multiple times in our `gulpfile.js`. As our `gulpfile.js` grows in complexity, we may find that we are introducing complex and multiple file path references. By creating a `gulp.config.js` file, we can simplify these references and make it easier to refactor and extend in the future. 

Angular Automation: Gulp Config

In this lesson, we are going to learn how to use `gulp.watch` to detect local file changes and execute additional Gulp tasks. To illustrate this concept, we are also going to hook up `gulp-jshint` to automation lint our JavaScript as we make changes to our code.

Angular Automation: Gulp Watch

Angular projects require automation. Period.

Angular Automation: Introduction to Gulp

In this lesson, we are going to learn how to copy assets from one place to another using Gulp. This is important as you start to prepare your source files to be deployed into production. We will learn how to implement `gulp.src`, `gulp.pipe` and `gulp.dest` as well as the **del** plugin as we copy our files from the source directory into a build directory.

Angular Automation: Copy Assets with Gulp

In this lesson, we are going to learn how to use the `gulp-inject` plugin to sanely and efficiently manage our file references with our HTML. Manually declaring JavaScript references will quickly get out of hand as your application grows in size and complexity. The `gulp-inject` plugin solves this problem by taking a stream of files, converting them into string references and then injecting those references into your HTML via annotations. 

Angular Automation: Gulp Inject

In this lesson, we are going to learn how to automatically serve our project via an HTTP server using `gulp-serve`. Being able to serve our project from an HTTP server allows us to bypass a myriad of development issues such as loading remote source files.

Angular Automation: Gulp Serve

In this lesson, we will learn how tasks work in Gulp. We will talk about how to define a task and what each parameter in the definition does. We will see how task dependencies work and talk about how to handle asynchronous issues using `run-sequence`.

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?

In this lesson, we learn how to get up and running with Gulp by initializing our project with ```npm init``` and then installing the Gulp CLI globally and then installing it locally to our project. We finish the lesson off by creating our first Gulp file and running our first Gulp task.

Angular Automation: Installing Gulp Globally and Locally

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.

In a CSS library like Bootstrap we can set a button's style to be "primary" or "secondary" by appending classes. For React components we want to be able to do this via props. Radium enables this by composing styles via an array. This mimicks the cascade of CSS.  

Radium: Updating Button Styles via Props

React's inline styles allow components to stand on their own by not requiring any external CSS. However HTML's style attributes don't support pseudo selectors like `:hover` and `:active`. By using Radium to listen to mouse events we can restore `:hover` and `:active` selectors to inline styles.

Gulp is a toolkit for automating painful or time-consuming tasks in your development workflow, so you can stop messing around and build something.

Building upon the `watch` task that we begin this lesson with, we’ll look at how to create a local development server using the `app` directory as the web root. By using Browsersync to achieve this, we can also instruct all connected browsers to automatically reload each time our bundle is re-generated. Browsersync has a public `.stream()` method that is designed exactly for this purpose.

Babel has support for the latest version of JavaScript through syntax transformers. These plugins allow you to use new syntax, right now without waiting for browser support.

What is already a nice workflow using Gulp, Browserify, Watchify & Browsersync to enable auto rebuilds & live browser reloading can be further improved by adding Babelify. A simple wrapper around the popular transpiler Babel, Babelify can ‘transform’ source files as they pass through our stream to enable certain Javascript features not yet available in the Browser or Node. We end the lesson by looking at how to generate & extract sourcemaps using `exorcist`.

Gulp and Browserify - Adding Babel & Source Maps

Browserify lets you require('modules') in the browser by bundling up all of your dependencies.

Let's look at the basics of setting up Gulp and Browserify. Creating a Gulp task from scratch, we'll cover how to utilise the Browserify API to generate a single `bundle.js` file, catch and log any errors that occur in the compilation process, transform the stream into a format that can be consumed by `gulp.dest` and finish by writing the bundle to a `dist` directory.

Gulp and Browserify - Initial Setup

A brief introduction to using GulpJS in your JavaScript application and creating your first Gulp task.

Installing and Writing a Default Task with Gulp

Beginning with a single Gulp task capable of generating a one-time Browserify bundle, we enable file-watching and incremental rebuilds by incorporating Watchify. We add a second task `watch` & refactor our initial code to enable the bulk of it to be re-used. We’ll look at exactly how to ‘wire’ these tools together and how the relationship between Watchify & Browserify can manifest into a seriously efficient workflow.

Gulp and Browserify - Hooking up Watchify

We will look at bundling your JavaScript files using Gulp, Gulp-Concat, and Gulp-Uglify

Bundling Your JavaScript Files with Gulp

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.
