Understanding Go&#s net/netip Addr Type: A Deep Dive

Detailed explanation of the net/netip package of Go language: Addr type Hello everyone! Today we will delve into the net/netip package of the Go language, focusing on the Addr type. If you've been working with Go's networking code, you may have encountered the old net.IP type. While it has served us well, it has some drawbacks that make it less suitable for modern network code. The net/netip package (introduced in Go 1.18) provides us with a more powerful and efficient way of handling IP addresses. Why choose net/netip.Addr? Before we get into the details, let's understand why this type exists. The traditional net.IP type is basically a byte slice ([]byte

Making Beautiful API Keys

Abstract: In order to improve the developer experience, AgentStation created the uuidkey package to encode UUID into a beautiful and easy-to-read API key. This package supports UUIDv7 and can decode keys for database sorting and indexing. Question: API keys are an important part of a user's initial interaction with AgentStation products. We want keys to be beautiful and easy to use, but there seems to be a lack of standards in the industry. As a developer-focused startup, we invest time and effort into finding the ideal solution. Most API keys suck: We have the following requirements for API keys: Secure Globally unique Sortable Excellent performance in Postgres Beautiful appearance However, most API keys are

Golang: Struct, Interface And Dependency Injection(DI)

Structures and Interfaces in Go Language: When to Use and How to Combine Dependency Injection This article will explore when to use structures in Go language, when to use interfaces, and how to use both to implement dependency injection (DI). We'll explain these concepts through a simple toy box metaphor. Real World Example: Toy Box Structure Think of a structure as a specific toy in a toy box, such as a car. The car has specific attributes such as color, size, and type (e.g., sports car). In programming, structures hold data about objects. Interface An interface is like a toy box that can hold any type of toys. It defines what the toy can do, such as rolling, making sounds, or lighting up. Any toy that can perform these operations can be placed

Go Concurrency: Mutexes vs Channels with Examples

Counter Synchronization in Go Concurrent Programming: Mutex, Buffered Channels and Unbuffered Channels When building concurrent applications in Go language, synchronization is crucial to ensure safe access to shared data. Mutex and Channel are the main tools for synchronization in Go. This article explores several ways to build safe concurrency counters. While the reference article solves this problem using a Mutex, we will also explore alternatives using buffered and unbuffered channels. Problem Description We need to build a counter that can be safely used concurrently. Counter code packagemaintypeCounterstruct{countint}func(c*Counter)Inc(){c
