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.

Adding the application code

Now, let's write the simple application code to test things out. This app is going to basically connect to our locally running MongoDB server, insert a few records as seed data, and then provide the output on whether or not the data was inserted properly into MongoDB. You can download a Gist of the code via this URL:

Using your editor of choice, create a new file named app.js and save it to the application root, which is the testapp folder. Just copy the content of the preceding Gist on to the app.js file.

Understanding the code

Now, let's go through and explain what each section of the code is doing.

//require the mongoClient from MongoDB module var MongoClient = require('MongoDB').MongoClient;

The preceding line requires the MongoDB Node driver that we installed via npm. This is the required convention used in Node.js for bringing in external file dependencies to the current file in context.

We will explain more about this in the coming chapters...
