- JWT Tokens in Golang: A Developer's Guide to Secure APIs
- Introduction In modern web development, secure and scalable authentication is crucial. JSONWebTokens (JWT) have become the standard way to achieve this goal. In this blog post, we will explore what JWT is, how it works, and how to implement it in Golang. What is JWT? JSONWebToken (JWT) is a compact, URL-safe way of representing claims for securely transmitting claims between two parties. It is commonly used to authenticate and authorize users in APIs and distributed systems. Structure of JWT A JWT consists of three parts separated by dots (.): Header.Payload.Signature Example: eyJhbGci

- Compile-Time Assertions in Go (Golang)
- The compile-time assertion mechanism of Go language is used to enforce specific conditions or constraints at the compilation stage rather than at runtime. If the conditions are not met, the compilation process will fail and report an error, which helps to detect errors as early as possible and ensure that the program satisfies certain invariants or assumptions before execution. Compile-time assertions are often used to ensure that data structures are sized as expected. Verify that the value of a constant or expression is as expected. Enforce type constraints or other compile-time checks. Compile-time assertions in Go The Go language itself does not directly support compile-time assertions like some other languages. However, we can achieve similar functionality with some clever techniques. Here are some common methods: Assert that a constant boolean expression is true (or false) at compile time: We can take advantage of the following features: The Go language specification is clear

- Week Seven Recap of #DaysOfCode
- Go Language Improvement and Algorithm Problem Solving This week marks an important milestone in my #100DaysOfCode learning journey. I studied the Go language in depth, consolidated my understanding of advanced concepts, and insisted on practicing algorithm questions on LeetCode. The following is a summary of this week's learning results: Go Language: In-depth Learning and Mastery This week has made significant progress in Go language learning, covering basic and advanced topics: Core concepts: I learned structures, interfaces, switch statements, Slicing and formatting lay a solid foundation for Go programming. Error handling and data structure modification: Understanding how to manage errors and modify data structures enables me to write robust and efficient code. Advanced Functions: I delved into higher-order functions, first-class

- Rust vs. Go: A Hands-On Comparison for Real Developers
- Rust vs. Go: A veteran developer’s practical comparison of the eternal debate: RustvsGo. It's like Coca-Cola versus Pepsi, Mac versus PC, or -- if you're really old-school -- Java versus C. Both are modern, excellent programming languages that can solve your programming problems, but they are very different. In this post, we’ll dive into it with examples, stories, and some old-fashioned blogging style. Let's fix this (or at least try to have fun). A quick overview of Rust: Your safety-conscious, detail-oriented friend who double-checks everything before hitting "send." Go: A relaxed and easy-going colleague who can complete tasks efficiently, pays attention to simplicity, and does not get hung up on minutiae.

- Ore: Advanced Dependency Injection Package for Go
- Ore: an advanced dependency injection package for the Go language Ore documentation website GitHub repository The Go language is known for its simplicity and high performance, but developers often face challenges when it comes to dependency management. Although the Go language does not have a built-in DI framework like some other languages, there are many third-party libraries that can help. Ore is one such package that provides a lightweight and efficient solution for dependency injection (DI) in Go applications. Ore aims to simplify and make DI more efficient without introducing significant performance overhead. Unlike many other DI libraries, Ore leverages Go generics rather than reflection or code generation, ensuring your application remains fast and type-safe. This makes Ore an ideal choice for those looking for efficient, easy-to-use D

- I Hated gRPC until this tool started Simplifying it!
- gRPC: Google's high-performance RPC framework, the first choice for building efficient APIs. It is fast, highly reliable, and well suited for microservice architecture. But frankly speaking, gRPC is not easy to get started with. From installing protoc and its plugins to managing the generated code, there is a lot of setup required before writing your first handler. This complexity often deters developers, despite its many advantages. Fortunately, GoFr significantly simplifies using gRPC by providing built-in support for observability, dependency management, and streamlined development processes. Challenges of using gRPC Although gRPC is great, it also has some pain points: Steep learning curve: setting up the protocol buffer compiler (protoc), installing the plug-in

- Mastering Pointers in Go: Enhancing Safety, Performance, and Code Maintainability
- Pointers in the Go language: a powerful tool for efficient data operations and memory management Pointers in the Go language provide developers with a powerful tool for directly accessing and manipulating the memory addresses of variables. Unlike traditional variables, which store actual data values, pointers store the memory location where those values reside. This unique feature enables pointers to modify original data in memory, providing an efficient method of data processing and program performance optimization. Memory addresses are represented in hexadecimal format (for example, 0xAFFFF) and are the basis for pointers. When you declare a pointer variable, it is essentially a special variable that holds the memory address of another variable, rather than the data itself. For example, the pointer p in the Go language contains the reference 0x0001, which directly points to another variable x
