REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with

Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill.

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Next.js 13 vs Remix: An In-depth case studyLast updated on 29 Sep 2023 by Prateek Surana • - min read When it comes to building web applications, React has been at the forefront for a while now, and its adoption continues to grow. Among the most common approaches to building web applications with React, Next.js stands out as one of the most preferred options. Next.js has also been in the limel
With pen and paper, anyone can write a journal entry, draw a diagram, perform a calculation, or sketch a cartoon. Digital tablets like the iPad or reMarkable can adapt pen and paper into the world of digital media. In doing so, they trade away some of paper’s advantages like cheapness and tangibility. In exchange, we get new computational powers like nondestructive editing and ease of transmission
Today, we are excited to announce the launch of .NET 10, the most productive, modern, secure, intelligent, and performant release of .NET yet. It’s the result of another year of effort from thousands of developers around the world. This release includes thousands of performance, security, and functional improvements across the entire .NET stack-from languages and developer tools to workloads-enabl
In this post I’ll walk through the full implementation of a Virtual DOM in a bit over 200 lines of JavaScript. The result is a full-featured and sufficiently performant virtual DOM library (demos). It’s available on NPM as the smvc package. The main goal is to illustrate the fundamental technique behind tools like React. React, Vue and the Elm language all simplify the creation of interactive web
Object Structure in JavaScript EnginesFrom a developer's perspective, objects in JavaScript are quite flexible and understandable. We can add, remove, and modify object properties on our own. However, few people think about how objects are stored in memory and processed by JS engines. Can a developer's actions, directly or indirectly, impact performance and memory consumption? Let's try to delve i

When a single-page application needs to fetch data from a remote source, it needs to do so while remaining responsive and providing feedback to the user during an often slow query. Five patterns help with this. Asynchronous State Handler wraps these queries with meta-queries for the state of the query. Parallel Data Fetching minimizes wait time.

Part of my job is to make JavaScript things go fast. Speed is a feature, and when working in an interpreted language, squeezing every last bit of performance can be the difference between a great product and unusable garbage. Anyway, how cool would it be to make JavaScript itself go faster? I’m not a C++ programmer, but that didn’t stop me before, so I thought I’d give it a try anyway! The objecti
