Building Serverless Web Applications

Overview of this book

This book will equip you with the knowledge needed to build your own serverless apps by showing you how to set up different services while making your application scalable, highly available, and efficient. We begin by giving you an idea of what it means to go serverless, exploring the pros and cons of the serverless model and its use cases. Next, you will be introduced to the AWS services that will be used throughout the book, how to estimate costs, and how to set up and use the Serverless Framework. From here, you will start to build an entire serverless project of an online store, beginning with a React SPA frontend hosted on AWS followed by a serverless backend with API Gateway and Lambda functions. You will also learn to access data from a SimpleDB database, secure the application with authentication and authorization, and implement serverless notifications for browsers using AWS IoT. This book will describe how to monitor the performance, efficiency, and errors of your apps and conclude by teaching you how to test and deploy your applications.

Preface

Chapter 3. Using the Serverless Framework

When developing a serverless project, you can group multiple features into a single big Lambda function or break each feature into its own small function. If you follow the second option, you will end up managing the deployment of dozens of different functions, each one of them with its own configuration and dependencies. Automating this process could be a real challenge, but it becomes an easy task when you use the Serverless Framework in your workflow. Besides handling the release process, the framework helps you architect the solution and manage different environments, and it provides a clean and succinct syntax for versioning the infrastructure.

In this chapter, you will learn how to configure and use the Serverless Framework. We will cover the following topics:

  • How to set up and start using the framework
  • Deploying a hello-world application
  • Creating endpoints and enabling CORS
  • Configuring events to trigger functions
  • Accessing other AWS resources
