pgxmock is a mock library implementing pgx - PostgreSQL Driver and Toolkit. It's based on the well-known sqlmock library for sql/driver.

pgxmock has one and only purpose - to simulate pgx behavior in tests, without needing a real database connection. It helps to maintain correct TDD workflow.

Free - no account required - alternative to ngrok for localhost asynchronous web development (e.g. webhooks)

This series is a step by step guide to creating an (almost) fully fledged Regex engine using Go. It explores the basics of Finite State Automata, incrementally creates a parser and compiler for turning strings into state machines, walks through the setup of a visualizer for the FSM node graph. All of the development is structured as a TDD project, and uses modern Go features such as fuzzing, generics, and profiling.

Some quick bits about how to do go.mod version bumps.

This is the second in a three-part series, extracted from my book The Power of Go: Tests, about test-driven development (TDD) in Go—in other words, building software in Go, guided by tests.

While Rust and Go are both modern programming languages that have learned from the mistakes of the previous generation, they manage concurrency in a completely different way, which, as we will see, has a huge impact on performance and developer experience.

Most modern programming language ecosystems provide assert functions in their testing libraries but not Go’s. Its standard testing package follows a more direct and to-the-point approach. In fact, there isn’t even a single assertion function in the testing package, and writing idiomatic tests in Go isn’t that different from writing application code.

Go is still a new language, and if you’re working with it, chances are that this is not your first programming language.
Coming from a different language, you bring forth both your experience as well as your biases. Things you used to do in your previous language might not be a good idea in Go.

Caesar is a Go web framework, designed for productivity. It takes inspiration from traditional web frameworks such as Ruby on Rails, Laravel, Django, Phoenix, AdonisJS, etc.

As of today, Go developers have to spend tremendous time architecting their web applications, setting up the project structure, configuring the database, choosing the right routing library, and so on.

Caesar aims to solve this problem by providing a set of tools and conventions that allow developers to focus on building their web applications, rather than setting them up.

If you use Timer.Reset() in Go 1.22 or earlier, you may be doing it wrong. Even the book 100 Go Mistakes (which is usually right about Go nuances) got it wrong.

River is a robust high-performance job processing system for Go and Postgres.

We are thrilled to introduce three new open-source libraries in Go that provide secure and efficient solutions:

- SafeText for YAML and shell command templating
- SafeOpen for opening files in a base directory
- SafeArchive for processing archive files

Go 1.23 is coming soon, so it's a good time to explore what's new. The official release notes are pretty dry, so I tried to remedy that by adding lots of interactive examples and showing what has changed and what the new behavior is.

Read on and see!
