Setting Up Your TYPO3 Development Environment
Before writing code, make sure your development environment is ready.

Core Concepts of TYPO3 Programming
TypoScript
TypoScript is a configuration language unique to TYPO3. It allows you to define the structure, layout, and behavior of your pages without using PHP. Think of it as the logic behind how content is displayed.
Fluid Templating Engine
Fluid is TYPO3’s templating system. It keeps your HTML clean and separate from backend logic. Templates are easy to manage, readable, and perfect for developers and designers working together.
Extensions
TYPO3 is built to be extended. You can either install pre-built extensions from the TYPO3 Extension Repository (TER) or develop custom ones to fit your specific needs. Extensions add features like blogs, galleries, forms, and more.
Building Custom Features in TYPO3
-
Creating Extensions
Use the Extension Builder or create extensions manually by setting up models, views, and controllers. TYPO3 follows the MVC (Model-View-Controller) pattern, keeping your code organized. -
Custom Content Elements
Tools like Mask, or custom-coded elements, let you build flexible and reusable content blocks tailored to your site’s needs. -
Backend Modules
You can expand the TYPO3 backend with your own admin panels, dashboards, or configuration tools for content editors and admins.
Debugging and Best Practices
-
Enable TYPO3's debug options in
LocalConfiguration.phpor through the Admin Panel. -
Use logging and exception handling to find and fix issues early.
-
Follow TYPO3's coding standards to keep your code consistent and easy to maintain.
