Overview of this book

Node.js revolutionizes server-side JavaScript development and empowers developers to build efficient, scalable, and versatile applications across a range of use cases. This book is written by a Node.js core collaborator and releaser and is the only book for beginners on Node.js. It takes you on a progressive learning path that will give you the skills needed to leverage Node.js. You’ll learn Node.js fundamentals and refresh your knowledge of JavaScript before transitioning to the development of modern web applications using Node.js, Express.js, and MongoDB. You’ll get hands-on with complex topics such as asynchronous programming, npm libraries, event-driven patterns for HTTP servers, RESTful API, and JSON Web Tokens. The final chapters will walk you through the deployment process, offering insights into various strategies, including bare metal setups, virtual machines, and containerization with Docker. You’ll also be guided through the use of Process Manager 2 (PM2) for efficient process management. By the end of this Node.js book, you'll have the skills to craft, test, and deploy Node.js web applications confidently and use this powerful stack in your day-to-day projects.

Data Persistence with MongoDB

In this chapter, we will explain how MongoDB works and why it is a great starting point for a web application. We will learn how to install MongoDB locally using containers with Docker and Docker Compose and also how to use external MongoDB instances.

We will explore how to use Mongoose to interact with MongoDB, and we will migrate our application to use MongoDB instead of a JSON file, we will use tests to grant that the migration was properly done and we didn’t introduce any regression.

In summary, here are the main topics that we will explore in this chapter:

  • How to set up MongoDB locally using containers with Docker and Docker Compose
  • How to use an Object–relational mapping (ORM) library such as Mongoose to interact with MongoDB
  • How to migrate our application to use MongoDB instead of a JSON file
  • How to test any application using MongoDB
  • How to use environment variables to store sensitive information and...
