Building high-performance REST APIs with Go has become a standard approach for powering systems at Google, Uber, Dropbox, and countless startups.

Go’s built-in testing package provides a powerful, minimalist framework for writing unit tests without external dependencies. Here are the testing fundamentals, project structure, and advanced patterns to build reliable Go applications.

The Saga pattern provides an elegant solution by breaking distributed transactions into a series of local transactions with compensating actions.

Generics in Go represent one of the most significant language features added since Go 1.0. Introduced in Go 1.18, generics enable you to write type-safe, reusable code that works with multiple types without sacrificing performance or code clarity.

Command-line interface (CLI) applications are essential tools for developers, system administrators, and DevOps professionals. Two Go libraries have become the de facto standard for CLI development in Go: Cobra for command structure and Viper for configuration management.

Developers often face the “works on my machine” dilemma due to dependency mismatches, tool versions, or OS differences. Dev Containers in Visual Studio Code (VS Code) solve this elegantly — by letting you develop inside a containerized environment configured specifically for your project.

This guide provides a comprehensive overview of available Go SDKs for Ollama and compares their feature sets.

Large Language Models (LLMs) are powerful, but in production we rarely want free-form paragraphs. Instead, we want predictable data: attributes, facts, or structured objects you can feed into an app. That’s LLM Structured Output.

Most prominent ORMs for GO are GORM, Ent, Bun and sqlc. Here is a little comparison of them with examples of CRUD operations in pure GO.

Here we have a description of The Model Context Protocol (MCP), short notes on how to implement an MCP server in Go, including message structure, protocol specifications.

Since standard Ollama doesn’t have a direct rerank API, you’ll need to implement reranking using Qwen3 Reranker in GO by generating embeddings for query-document pairs and scoring them.

This little Reranking Go code example is calling Ollama to generate embeddings for the query and for eache candidate document, then sorting descending by cosine similarity.

Generating PDF documents programmatically can be an important feature in your application. Here we explore and give short review with examples of the libraries available in the Go programming language (Golang) for generating PDF files.

• For a direct Beautiful Soup analogue in Go, use soup.
• For CSS selector support, consider goquery.
• For XPath queries, use htmlquery.
• For another Beautiful Soup-inspired option, look at Node.

If you’re looking for a Beautiful Soup equivalent in Go, several libraries offer similar HTML parsing and scraping functionality:

In my new Go project that was using GORM I started getting error: pq: got 2 parameters but the statement requires 1

I aggregated some VS Code extentions installation statistics by different programming languages. And the most popular is Python. Then C++.
