What is a Golang map? Why is it useful? How does it compare to a slice? How do you declare a map? How do you initialize a map in Go? Fear not; all these questions are answered in this friendly introduction to one of Go’s most powerful features. Call ’em what you like—hashes, dictionaries, associative […]
Structured logging involves producing log records in a well-defined format (usually JSON), which adds a level of organization and consistency to application logs, making them easier to process. Such log records are composed of key-value pairs that capture relevant contextual information about the event being logged, such as the severity level, timestamp, source code location, […]
The other day I was pondering the prevalence of single-method interfaces (SMI) in Go, and what makes them so practical and helpful. SMIs have proven to be a very successful software modeling tool for Go programmers, and you find them all over Go code-bases. I tried to think about the fundamentals, which brought me to […]
A migration guide from github.com/hashicorp/go-multierror to the std library errors package. In go1.20 support for “multierrors” was added. Why migrate? # Migrating from community go modules to standard library implementations is almost always a no-brainer if it provides like for like functionality. Packages in the core go standard library such as errors are covered by the go1.0 backwards compatibility guarantee [0].Because of […]
Go is designed to make concurrency easier than it is in other languages, but at Sourcegraph, I still found myself running into the same problems repeatedly when writing concurrent code. In particular, it is difficult to write concurrent code that operates reasonably in the face of panics. We don’t want the entire process to crash […]
There are a lot of materials about how to write services, where at first you need to choose some framework to use, then comes wiring of handlers, configs, logs, storage, etc, not to mention deploying that service somewhere. We’ve been writing services for quite some time and more often than not you’d just want to […]
Wails is a framework that enables development of desktop applications using the Go programming language. In this article, I will provide an in-depth look at the initial project structure when a new Wails application is created. By examining this structure, you will better understand how Wails operates and what the development cycle entails. Installing Wails Install Wails using go install. Initialize new golang […]
Introduction# Go 1.20 introduces an experimental concept of “arenas” for memory management, which can be used to improve the performance of your Go programs. In this blog post, we’ll take a look at: What Are Memory Arenas?# Go is a programming language that utilizes garbage collection, meaning that the runtime automatically manages memory allocation and […]
Golang is a popular programming language known for its simplicity, performance, and concurrency. It is often used for building web applications, and several tools are available for integrating with APIs. This blog post will discuss how to use the OpenAI Chat API in Golang. To use the OpenAI Chat API in Golang, you must obtain […]
The main objective of Centrifugo is to manage persistent client connections established over various real-time transports (including WebSocket, HTTP-Streaming, SSE, WebTransport, etc – see here) and offer an API for publishing data towards established connections. Clients subscribe to channels, hence Centrifugo implements PUB/SUB mechanics to transmit published data to all online channel subscribers. Centrifugo employs Redis as its […]
