Guides

The primers explain what each technology is; these guides take you through building and shipping something real with it. Each one includes complete, working code, explains why it's written the way it is, and covers the problems people most often hit along the way.

Build something

• Your first full-stack app: Vue + Flask + SQLite - a complete to-do app, from database to interface, small enough to understand every line.
• Your first PHP + MySQL site on shared hosting - a secure guestbook with prepared statements, escaped output and credentials kept out of the public folder.
• Build a Node + Express + PostgreSQL API - a REST API with connection pooling, validation and Express 5 error handling, deployed with a free hosted database.
• Build a real-time chat with Firestore - live updates in about 40 lines of JavaScript, plus security rules that actually protect it.

Ship it

• Deploy a Flask app on Render - gunicorn, environment variables, the free tier's limits, and fixes for the common errors.
• Deploy a React (Vite) app - Netlify, Cloudflare Pages, GitHub Pages or shared hosting, and the fixes for blank pages and 404s on refresh.

Which guide should I start with?

If you've just taken the quiz, your result's full write-up links to the guide that fits it. Otherwise: total beginners should start with the Vue + Flask + SQLite app; anyone on shared hosting should start with PHP + MySQL; and if you already know some JavaScript and want job-ready skills, start with the Node + PostgreSQL API.
