Quicktemplate for Go: Like Jinja2 for Python, but Never html/template

Apr 09, 2025

Recently, when organizing the code of our project, I found that the code for many activities was very similar in structure and the functions it provided. To facilitate future development, I spent some time writing a tool for generating code frameworks to minimize repetitive work. The code itself is not complex and is closely related to the project code, so I won't go into details here. During this process, I found that the Go standard template libraries `text/template` and `html/template` were rather restrictive and inconvenient to use. I learned from GitHub about the third-party template library `quicktemplate`, which is powerful, has a simple syntax, and is easy to use. Today, we're going to introduce `quicktemplate`.

Getting Started with NestJS: Build Skills Step by Step

Apr 04, 2025

From the native HTTP module of Node.js to Express, and then to NestJS and Next.js, we have witnessed the continuous evolution of web application development technologies. With its powerful architectural design capabilities, NestJS provides a structured solution for enterprise-level application development, making it an ideal choice for dealing with complex projects. Next.js, on the other hand, shows unique advantages in the fields of full-stack applications and front-end rendering. Although Express has certain limitations in large projects, it still has irreplaceable value when quickly building lightweight web applications. Developers should choose the most suitable technical solution according to the specific requirements of the project. Subsequent articles will delve into the core concepts and practical skills of NestJS to help developers quickly master this powerful framework.

Async/Await in Python: A Complete Guide to Coroutines

Apr 03, 2025

In addition to the above asynchronous methods, there are other asynchronous approaches in Python, such as using callback functions or third - party libraries like Gevent. Each method has its own advantages and limitations. For example, threads are suitable for I/O - bound tasks but are limited by the GIL (Global Interpreter Lock); multiprocessing is suitable for CPU - intensive tasks but has higher memory overhead; third - party libraries provide specialized functions and optimizations but may increase the complexity of the project. In contrast, the `async/await` syntax provides a more modern and readable way of asynchronous programming and is currently the recommended method for handling asynchronous operations in Python.

Creating a Gin-Like Web Framework in Go from the Ground Up

Mar 30, 2025

In modern web development, an efficient and flexible routing system is one of the core components of building web applications. The Go programming language is highly favored in the field of web development due to its high performance, simplicity, and powerful standard library. The `net/http` package in Go is the implementation of an HTTP server in the standard library. Although it is powerful, it is relatively low-level. If you want to handle routing like in lightweight web frameworks such as Gin, we can implement a simplified router ourselves. This article will provide a detailed introduction on how to use the `net` package in Go to implement an HTTP server similar to Gin. At the same time, it will delve into HTTP-related knowledge, common routing implementation methods, and how to implement middleware based on this.
