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

How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru

👋 This page was last updated ~4 years ago. Just so you know. In the two years since I’ve posted I want off Mr Golang’s Wild Ride, it’s made the rounds time and time again, on Reddit, on Lobste.rs, on HackerNews, and elsewhere. And every time, it elicits the same responses: You talk about Windows: that’s not what Go is good at! (Also, who cares?) This is very one-sided: you’re not talking about th

There is an area of Python that many developers have problems with. This is an area that has seen many different solutions pop up over the years, with many different opinions, wars, and attempts to solve it. Many have complained about the packaging ecosystem and tools making their lives harder. Many beginners are confused about virtual environments. But does it have to be this way? Are the current
"MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools." ― Anthropic TL;DR I would like for this to turn out to be a skill

Update: I originally published this post few months ago, and it only covered Turbo Drive and Turbo Frames then, with a static site. I've since had a bunch of conversations with people working with other tech stacks (Rust, PHP, and Go) wanting to integrate Hotwire into their front-ends, and everyone kept asking about Turbo Streams, since it needs a back-end server. So I've updated the post to build
Adopting Wide Event-style instrumentation has been one of the highest-leverage changes I've made in my engineering career. The feedback loop on all my changes tightened and debugging systems became so much easier. Systems that were scary to work on suddenly seemed a lot more manageable. Lately there have been a lot of good blog posts on what "Wide Events" mean and why they are important. Here are

The Twelve-factor app is a methodology for building software-as-a-service apps that was first formulated by developers associated with Heroku.

Tapping The Sign I am getting frustrated by the number of people calling any HTTP-based interface a REST API. Today’s example is the SocialSite REST API. That is RPC. It screams RPC.

In other words, if the engine of

Automated tests are important. Without them, programmers waste a huge amount of time manually checking and fixing their code. Unfortunately, many automated tests also waste a huge amount of time. The easy, obvious way to write tests is to make broad tests that are automated versions of manual tests. But they’re flaky and slow. Folks in the know use mocks and spies (I say “mocks” for short in this
The architecture of Web 3.0 applications (or "DApps") are completely different from Web 2.0 applications.

In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
