Writing Go applications in an isolated environment with Docker comes with some great advantages. You get a clean GOPATH, the bare essentials for developing, and you can easily change which Go version you’re developing against. In this quick tutorial, we’re going to show you how to structure a Go application with Docker Compose as your development environment.

Organizations that depend on distributed systems often write their applications in Go to take advantage of concurrency features like channels and goroutines (e.g., Heroku, Basecamp, Cockroach Labs, and Datadog). If you are responsible for building or supporting Go applications, a well-considered logging strategy can help you understand user behavior, localize errors, and monitor the performance of your applications.

In this tutorial we are going to learn how to instrument Golang code to expose application custom metrics using expvar. This will help you monitor availability, health and performance of your Go application.

We’ve seen folks do amazing things using our Honeycomb Beelines–getting their apps instrumented in next-to-no time, expanding their observability, growing their understanding of what is happening in their code in production. Now, prepare to do more with improved tracing support!

We’re happy to announce that our Go tracer v1.0.0 has been released. The latest version represents a major overhaul, and includes performance improvements, more robust compatibility with tracing standards, and a new and improved API. It incorporates continuous feedback not only from our community, but also from extensive internal usage here at Datadog.

Rollbar is proud to announce its error monitoring SDK for the Go language (aka Golang). It’s an open source programming language originally created by Google and is growing in popularity. It’s a low-level language like C, but also offers garbage collection, an easy-to-use package system, and other features.

Want magical per-request instrumentation to roll effortlessly out of your Go app without even looking like you’re trying? Meet the Honeycomb Beeline for Go!

We use Node.js extensively in our production apps. When we started with golang, the major discussion point amongst us was, for a beginner how golang dependency management is supposed to work. Vendoring was the only method for golang dependency management. In this, you save a local copy of the dependent libraries that your application shall use. In Node.js world, dependency is managed using packages.json.
