Hands-On Serverless Applications with Go

By: Mohamed Labouardy

Overview of this book

Serverless architecture is popular in the tech community due to AWS Lambda. Go is simple to learn, straightforward to work with, and easy to read for other developers; and now it's been heralded as a supported language for AWS Lambda. This book is your optimal guide to designing a Go serverless application and deploying it to Lambda. This book starts with a quick introduction to the world of serverless architecture and its benefits, and then delves into AWS Lambda using practical examples. You'll then learn how to design and build a production-ready application in Go using AWS serverless services with zero upfront infrastructure investment. The book will help you learn how to scale up serverless applications and handle distributed serverless systems in production. You will also learn how to log and test your application. Along the way, you'll also discover how to set up a CI/CD pipeline to automate the deployment process of your Lambda functions. Moreover, you'll learn how to troubleshoot and monitor your apps in near real-time with services such as AWS CloudWatch and X-ray. This book will also teach you how to secure the access with AWS Cognito. By the end of this book, you will have mastered designing, building, and deploying a Go serverless application.

In this section, we will learn how to build a web application that will call the API Gateway invocation URL that we built in previous chapters and list the movies, as follows:

For each movie, we will display its cover image and title. In addition, a user can filter the movies by their categories by clicking on the button to the right of Horror . Finally, to add a new movie to the database, a modal will pop up if the user clicks on the New button on the navigation bar. The modal will ask the user to fill in the following fields:

Now that the application mock-ups are defined, we will use a JavaScript framework to build the web application quickly. For example, I will be using Angular 5, which is currently the latest stable version of Angular.
