Full-Stack Web Development with Go

By: Nanik Tolaram, Nick Glynn

Overview of this book

Go is a modern programming language with capabilities to enable high-performance app development. With its growing web framework ecosystem, Go is a preferred choice for building complete web apps. This practical guide will enable you to take your Go skills to the next level building full stack apps. This book walks you through creating and developing a complete modern web service from auth, middleware, server-side rendering, databases, and modern frontend frameworks and Go-powered APIs. You’ll start by structuring the app and important aspects such as networking, before integrating all the different parts together to build a complete web product. Next, you’ll learn how to build and ship a complete product by starting with the fundamental building blocks of creating a Go backend. You’ll apply best practices for cookies, APIs, and security, and level up your skills with the fastest growing frontend framework, Vue. Once your full stack application is ready, you’ll understand how to push the app to production and be prepared to serve customers and share it with the world. By the end of this book, you’ll have learned how to build and ship secure, scalable, and complete products and how to combine Golang with existing products using best practices.

Adding metrics using Prometheus

As OpenTelemetry is vendor-agnostic, it provides a wide variety of support for monitoring, exporting, and collecting metrics and one option is Prometheus. A complete list of different projects supported by OpenTelemetry can be found at https://opentelemetry.io/registry/. Prometheus is an open source monitoring and alerting system server that is widely used in cloud environments; it also provides libraries for a variety of programming languages.

In the previous section, we saw how to add tracing capabilities to our application and how to retrieve the traces by using Jaeger. In this section, we are going to take a look at how to create metrics using the OpenTelemetry library. Metrics allow us to get instrumentation information for our applications; it can provide answers to questions such as the following:

  • What is the total number of requests processed in service A?
  • How many total transactions are processed via payment gateway B?
