Learn Aphrodite, Karma and Reactfire

webpack is a tool to build JavaScript modules in your application. To start using webpack from its cli or api, follow the Installation instructions. webpack simplifies your workflow by quickly constructing a dependency graph of your application and bundling them in the right order. webpack can be configured to customise optimisations to your code, to split vendor/css/js code for production, run a development server that hot-reloads your code without page refresh and many such cool features.

There are several steps involved with setting up [`Karma`](http://karma-runner.github.io/) to work on your webpack project. In this first step we'll initialize our karma configuration and setup our `package.json` `scripts`.

Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework.

[Chai](https://npmjs.com/package/chai) assertions work great with the [Mocha](https://npmjs.com/package/mocha) testing framework. In this lesson we'll walk through out to install Chai and [karma-chai](https://npmjs.com/package/karma-chai) so you can use the `expect` assertions in your tests.

Use Chai assertions for tests in a Karma project

When writing tests run by Karma for an application that’s bundled with webpack, it’s easiest to integrate webpack and Karma directly together. In this lesson we’ll see how to utilize the [`karma-webpack`](https://npmjs.com/package/karma-webpack) plugin and reuse our existing webpack configuration to preprocess our test files with webpack.

Use Karma for Unit Testing with Webpack

React is one of the web’s most popular frameworks for building JavaScript applications.

[Aphrodite](https://github.com/Khan/aphrodite) is a library styling React components.

You get all the benefits of inline styles (encapsulation, no build step, no CSS cascade, building up styling with JavaScript instead of a preprocessor language) with all the benefits of CSS (animations and transitions, pseudo-classes, media queries).

Learn how to use Aphrodite to style reusable React components.
