Ever wondered how those Symfony bundles you install with Composer actually get made? In this course, you’ll build one from scratch and see how all the pieces fit together. From the first composer init to wiring services, adding entities, and creating config options, you’ll get the full behind-the-scenes tour of bundle development.
You’ll learn how to:
- Set up a modern Symfony 6.1+ bundle structure
- Design your code with backwards compatibility in mind so your bundle can evolve without breaking users
- Wire services, entities, and configuration the bundle way
- Add a Twig extension
- Create console commands
- Write tests to keep your bundle solid
- Keep code style consistent with PHP-CS-Fixer
- Configure and run static code analysis with PHPStan
- Push it to GitHub and set up GitHub Actions to tests across different PHP and Symfony versions
- Create a Symfony Flex recipe so installation feels like magic
By the end, you’ll know how to package your own code into a polished, reusable bundle that’s ready to share - whether with your team, your future self, or the entire Symfony community.
