A Complete Teaching Book

The Delphi Way

Object Pascal, FireMonkey, pas2js, and PostgreSQL — from first program to production.

Eighty-one chapters and five appendices take a new or returning Delphi developer end-to-end through the language, object-oriented design, real applications, components, cross-platform work, the web via pas2js, architecture for long-lived systems, the full PostgreSQL stack, and the productionising work that turns a good prototype into something you can run.

If a topic is in scope for working Delphi developers in 2026, it is in this book. The chapters are deliberately opinionated; the conventions are consistent; the listings are runnable.

Who this book is for

Beginners who want to read and write idiomatic Object Pascal without first wading through twenty years of folklore.

Working Delphi developers updating tired habits — properties without bare F-fields, exceptions without Exit, parallel work without anonymous-method spaghetti, web work without leaving the language.

Teams looking for the house style their codebase has been missing — consistent code, consistent rules, consistent reasoning.
