Building Serverless Node.js Apps on AWS

Most developers who want to go serverless stall on the same question: where do I begin? This book is built to answer it.

The hardest part of moving to a serverless architecture is rarely the technology. It is knowing where to start, what to wire up first, and what to verify before real users arrive. This book removes that roadblock and gives you a clear, practical path onto Amazon Web Services with Node.js.

It is a step-by-step guide that takes you from an empty project to a fully deployed, working API. Using the Serverless Framework, you will build a real book collection management API, schedule background jobs, and add notifications with Amazon SNS and SES. From there you will secure the API with API keys, test it with Jest, add a linter for consistent code, and stand up a complete CI/CD pipeline.

The approach is deliberately hands-on. Rather than cataloging every possible option, it follows one real project from start to finish so the pieces actually connect.

This second edition adds an entirely new chapter on generative AI with Amazon Bedrock. You will see how to call Bedrock from a Serverless project in the two places teams actually use it: as background enrichment on the event bus after a record is created, and as a synchronous endpoint your users can wait on. The companion code is brought current, too, targeting the latest Node.js and an up-to-date toolchain.

It is written for developers who want a real on-ramp to serverless, whether you are putting together a proof of concept for your team, shipping a side project, or helping a small team get to market without breaking the bank.

Every chapter closes with a quiz and critical thinking questions to lock in what you have learned. You also get worked solutions, appendices, and access to the full source code from the examples in the book.

Stop wondering where to begin. Start building.
