The Express.js REST API journey continues! Move from models to full DAOs and DTOs, validate requests with middleware, separate services from controllers, and prepare for a real database.

Learn practical TypeScript patterns with interfaces and extended classes. Avoid messy console.log() statements with Winston and the Node.js debug module. Create an Express.js-powered REST API back end from scratch!

Feedback on an enterprise web app prompted an experiment. Could a WhatsApp chatbot replace it? Would people like it better? Would it be more useful?

The main artifact of all your work is most likely plain text files. So why don't you use Notepad to create them? Find out how the Language Server Protocol can transform text editors into code editors, without coupling.

Internet privacy's cutting-edge technology includes encrypted server name indication (ESNI) and encrypted DNS in the form of DNS over HTTPS (DoH). Find out what they are, why they exist, and how they work.

HTTP/3 is on the horizon, but many aren't even familiar with HTTP/2 yet. Find out what HTTP/3 means for web development, administration, and the internet.

Micro-frontend architectures decompose a front-end app into individual, semi-independent "microapps" working loosely together. This can help make large projects more manageable, e.g. when transitioning from legacy codebases.

WordPress code, especially back-end PHP code, is often a mess—even in WP core! But legacy code is no excuse. Find out how to develop WP customizations the right way, so your code is readable and maintainable.

Types and testable code are two of the most effective ways of avoiding bugs. In this tutorial, discover TypeScript best practices while you create a Discord bot from scratch.
