MongoDB Fundamentals

Overview of this book

MongoDB is one of the most popular database technologies for handling large collections of data. This book will help MongoDB beginners develop the knowledge and skills to create databases and process data efficiently. Unlike other MongoDB books, MongoDB Fundamentals dives into cloud computing from the very start – showing you how to get started with Atlas in the first chapter. You will discover how to modify existing data, add new data into a database, and handle complex queries by creating aggregation pipelines. As you progress, you'll learn about the MongoDB replication architecture and configure a simple cluster. You will also get to grips with user authentication, as well as techniques for backing up and restoring data. Finally, you'll perform data visualization using MongoDB Charts. You will work on realistic projects that are presented as bitesize exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. Many of these mini-projects are based around a movie database case study, while the last chapter acts as a final project where you will use MongoDB to solve a real-world problem based on a bike-sharing app. By the end of this book, you'll have the skills and confidence to process large volumes of data and tackle your own projects using MongoDB.

Connecting to the Driver

At a high level, the process of using the Node.js driver with MongoDB is similar to connecting directly with the shell. You will specify a MongoDB server URI, several connection parameters, and you can execute queries against collections. This should all be quite familiar; the main difference will be that these instructions will be written in JavaScript instead of Bash or PowerShell.

Introduction to Node.js

Since the objective of this chapter is not to learn Node.js programming, we will briefly cover the fundamentals to ensure that we can create our MongoDB application. The js in Node.js stands for JavaScript because JavaScript is the programming language that Node.js understands. JavaScript typically runs in a browser. However, you can think of Node.js as an engine that executes the JavaScript files on your computer.

Over the course of this chapter, you will write JavaScript (.js) syntax and execute it with Node.js. Although you can write JavaScript...
