Learn Karma, Mongoose and Particle

Mongoose provides a straight-forward, schema-based solution to model your application data. It includes built-in type casting, validation, query building, business logic hooks and more, out of the box.

One of the great things about NoSQL databases is that you do not have to decide on your data schema while developing. As you get closer to production though, you'll often want to more clearly define the shape of the data you are working with.

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

Mongoose allows you to easily select resources by ID from your MongoDB. This is an important aspect to creating an API.

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`.

Initialize a Webpack Project with Karma for Testing

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.
