Web Development with MongoDB and Node - Third Edition

Overview of this book

Node.js builds fast, scalable network applications while MongoDB is the perfect fit as a high-performance, open source NoSQL database solution. The combination of these two technologies offers high performance and scalability and helps in building fast, scalable network applications. Together they provide the power for manage any form of data as well as speed of delivery. This book will help you to get these two technologies working together to build web applications quickly and easily, with effortless deployment to the cloud. You will also learn about angular 4, which consumes pure JSON APOIs from a hapi server. The book begins by setting up your development environment, running you through the steps necessary to get the main application server up-and-running. Then you will see how to use Node.js to connect to a MongoDB database and perform data manipulations. From here on, the book will take you through integration with third-party tools to interact with web apps. You will see how to use controllers and view models to generate reusable code that will reduce development time. Toward the end, the book supplies tests to properly execute your code and take your skills to the next level with the most popular frameworks for developing web applications. By the end of the book, you will have a running web application developed with MongoDB, Node.js, and some of the most powerful and popular frameworks.

The tools of the trade

Let's start by taking a look at the various tools and libraries we will use to run and write our tests. There are three main concepts that we will need to cover before we can actually start writing real tests.

The first is a test runner, or the framework we use to run our suite of tests.

Most of the frameworks follow Test Driven Development (TDD), and their process relies on the following steps:

  1. It defines a unit test.
  2. It implements the unit.
  3. It executes the test and verifies that the test passes.

The second concept is the assertion library itself--the language we use to write our tests. A special version of using assertion language to design and build pieces of functionality incrementally, guided by an expected behavior, is Behavior Driven Development (BDD).

For both TDD and BDD, we can use the Mocha testing framework; however, we will be writing assertions using a special assertion library called Chai.js.

Finally, we'll take a look at the idea of spies and stubs, which are...
