Learn AWS Serverless Computing

By: Scott Patterson

Overview of this book

Serverless computing is a way to run your code without having to provision or manage servers. Amazon Web Services provides serverless services that you can use to build and deploy cloud-native applications. Starting with the basics of AWS Lambda, this book takes you through combining Lambda with other services from AWS, such as Amazon API Gateway, Amazon DynamoDB, and Amazon Step Functions. You’ll learn how to write, run, and test Lambda functions using examples in Node.js, Java, Python, and C# before you move on to developing and deploying serverless APIs efficiently using the Serverless Framework. In the concluding chapters, you’ll discover tips and best practices for leveraging Serverless Framework to increase your development productivity. By the end of this book, you’ll have become well-versed in building, securing, and running serverless applications using Amazon API Gateway and AWS Lambda without having to manage any servers.

Building SPAs with Serverless Framework

As well as building and maintaining the resources and configurations with CloudFormation, the CLI, or in the console directly, we can also manage the components in the Serverless Framework. To make it even easier, we can leverage the serverless SPA plugin:

  1. To install it, this time, we're going to use the serverless install command to create the new service. That's because this command has an option to input a URL, and we're going to input a URL that contains a boilerplate structure for an SPA project. Have a look at the following command:
sls install 
--url https://github.com/serverless/examples/tree/master/aws-node-single-page-app-via-cloudfront
--name hello-website

What this command does is seed our service with the configuration we need to get started.

  1. After running the command, have a look at the serverless.yml...
