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.

Preface

The basics of Node.js


With the basics of JavaScript out of the way, let's focus on some of the basics of Node. We will start by understanding the node.js core architecture. The significance of different node features lies in its architecture and way it works. Let us study it carefully in the following section.

Node.js architecture

The web application normally follows three tier web architecture consisting of client, web server, and data source. In our context, we have created a web app server using Node.js. As we discussed in chapter 1, Welcome to JavaScript in The Full Stack, Node.js follows a single threaded architectural model. To reduce the memory leak and understand asynchronousity while writing the code, we need to understand how Node.js works.

The following diagram depicts a visual representation of code:

Every processing component is sequenced in the following order"

  1. The client sends a request (consider an HTTP request).
  2. The Chrome's v8 engine is a just-in-time (JIT) compiler. Once the...
