RESTful Web API Design with Node.js - Second Edition

By: Valentin Bojinov

Overview of this book

In this era of cloud computing, every data provisioning solution is built in a scalable and fail-safe way. Thus, when building RESTful services, the right choice for the underlying platform is vital. Node.js, with its asynchronous, event-driven architecture, is exactly the right choice to build RESTful APIs. This book will help you enrich your development skills to create scalable, server-side, RESTful applications based on the Node.js platform. Starting with the fundamentals of REST, you will understand why RESTful web services are better data provisioning solution than other technologies. You will start setting up a development environment by installing Node.js, Express.js, and other modules. Next, you will write a simple HTTP request handler and create and test Node.js modules using automated tests and mock objects. You will then have to choose the most appropriate data storage type, having options between a key/value or document data store, and also you will implement automated tests for it. This module will evolve chapter by chapter until it turns into a full-fledged and secure Restful service.

Preface

Testing a Mongoose model with Mocha


Mocha is one of the most popular testing frameworks for JavaScript; its main goal is to provide an easy way to test asynchronous JavaScript code. Let's install Mocha globally so that we can make it available to any Node.js application that we may develop in the future:

npm install -g mocha

We will also need an assert library that can be used together with Mocha. The Should.js library module is easy to use and it will be our choice, so let's install it globally too:

npm install -g should

Now that we have our testing modules installed, we need to specify our testcase file path in the package.json file, let's modify it by adding a test element pointing to Mocha and the testcase file in the script node:

{ 
"name": "chapter4", 
"version": "0.0.0", 
"private": true, 
"scripts": { 
"start": "node ./bin/www", 
"test": "mocha test/contact-model-test.js" 
 }, 
"dependencies": { 
"body-parser": "~1.13.2",
