A complete journey from idea to production

This practical guide uses TestHarbour as its case study to show how ChatGPT and Codex CLI fit into the complete development process, from the first idea to a live website you can maintain.

Throughout the book, you’ll learn how to divide the work between ChatGPT, Codex CLI, and yourself: planning, implementing, reviewing, and verifying each step.

Inside, you’ll learn how to

Turn a rough idea into focused requirements and clear acceptance checks.
Plan your pages, data, APIs, and the responsibilities of each part of the system.
Build a Next.js frontend, a Go backend, and a PostgreSQL database.
Use Git and Docker to make development repeatable and changes easier to manage.
Test whether features work correctly and troubleshoot problems.
Deploy to a VPS and configure your domain, DNS, Cloudflare, and HTTPS.
Back up your data and update the application safely.

Written for practical learners

Written for beginners and independent builders, the guide explains technical ideas before introducing commands. Each major step includes a practical action, an expected result, and a way to check that it succeeded.

Apply the workflow to your idea

You don’t need to build an exam-practice website. The decisions and workflow can guide your own project, too.

Build faster without giving up control

AI can help you move faster. This book shows you how to use that help while keeping control of what you build.
