Overview of this book

Gin is a high-performance HTTP web framework used to build web applications and microservices in Go. This book is designed to teach you the ins and outs of the Gin framework with the help of practical examples. You’ll start by exploring the basics of the Gin framework, before progressing to build a real-world RESTful API. Along the way, you’ll learn how to write custom middleware and understand the routing mechanism, as well as how to bind user data and validate incoming HTTP requests. The book also demonstrates how to store and retrieve data at scale with a NoSQL database such as MongoDB, and how to implement a caching layer with Redis. Next, you’ll understand how to secure and test your API endpoints with authentication protocols such as OAuth 2 and JWT. Later chapters will guide you through rendering HTML templates on the server-side and building a frontend application with the React web framework to consume API responses. Finally, you’ll deploy your application on Amazon Web Services (AWS) and learn how to automate the deployment process with a continuous integration and continuous delivery (CI/CD) pipeline. By the end of this Gin book, you will be able to design, build, and deploy a production-ready distributed application from scratch using the Gin framework.

Summary

In this chapter, you learned how to instrument Gin application code to expose application-side metrics using Prometheus. You saw how to build a dynamic dashboard with Grafana to monitor the overall health of a Gin application in near-real time, as well as how to trigger a Slack alert when certain thresholds are crossed.

Then, you learned how to stream Gin logs to a centralized logging platform built using open source tools such as Logstash, Elasticsearch, and Kibana. Along the way, you learned how to parse Gin logs with Grok patterns and how to build charts on top of these parsed fields.

Congratulations! Now, you can design, build, and deploy a distributed Gin application from scratch. You also have a solid foundation regarding how to automate the deployment workflow and monitor a running Gin application in production.
