Serverless Applications with Node.js : Using AWS Lambda and Claudia.js

Serverless Applications with Node.js walks you through building serverless apps on AWS using JavaScript. Inside, you'll discover what Claudia.js brings to the table as you build and deploy a scalable event-based serverless application, based around a pizzeria that's fully integrated with AWS services, including Lambda and API Gateway. Each chapter is filled with exercises, examples, tips, and more to make sure you're ready to bring what you've learned into your own work. Foreword by Gojko Adzic. About the Technology The benefits of cloud-hosted serverless web apps are undeniable: lower complexity, quicker time to market, and easier scalability than traditional, server-dependent designs. And thanks to JavaScript support in AWS Lambda and powerful new serverless API tools like the Claudia.js library, you can build and deploy serverless apps end to end without learning a new language. About the Book Serverless Applications with Node.js teaches you to design and build serverless web apps on AWS using JavaScript, Node, and Claudia.js. You'll master the basics of writing AWS Lambda functions, along with core serverless patterns like API Gateway. Along the way, you'll practice your new skills by building a working chatbot and a voice assistant with Amazon Alexa. You'll also discover techniques for migrating existing apps to a serverless platform. What's inside • Authentication and database storage • Asynchronous functions • Interesting real-world examples • Developing serverless microservices About the Reader For web developers comfortable with JavaScript and Node.js. About the Author Slobodan Stojanović and Aleksandar Simović are AWS Serverless Heroes and core contributors to the Claudia.js project. They are also coauthors of Desole, an open source serverless errortracking tool, and the lead developers of Claudia Bot Builder.

AWS Lambda. API Gateway. Node.js. Microservices. Cloud-hosted functions. That's an impressive-sounding list, but what's the point? Beyond the buzzwords are real benefits like fast design-to-deployment times, low hosting costs, and efficient scaling and application management, along with real technologies that deliver them. Serverless Apps with Node and Claudia.js walks you through building serverless apps on AWS using JavaScript. Inside, you'll create a full project designed to help you understand and apply general serverless design principles and concepts. Along the way, you'll also discover what Claudia brings to the table as you build and deploy a scalable event-based serverless application that is fully integrated with AWS services including Lambda and API Gateway. You'll learn to simplify the design and development process so you can focus on getting your application deployed as fast as possible without sacrificing quality. Plus, you'll learn how to migrate your existing Express apps to serverless!
