6. CREATE A NEW SYMFONY PROJECT

7. FOLDER STRUCTURE

8. SO, WHAT ACTUALLY IS
SYMFONY FLEX
•Symfony flex is composer plugin that overrides default behavior of the require,
update, and remove commands.
•Symfony 4 requires Flex by default (line "symfony/flex": "^1.0" in composer.json)
•During package installation it looks for a "recipe" for a given <package_name>
inside https://github.com/symfony/recipes repository
•config/bundles.php

9. Recipes are simple
manifest files with
optional additional files,
which defines how this
particular package
should be installed

10. ROUTING
- composer require annotations
- Annotations, YAML, XML, PHP
- Wildcard
- Placeholder
- bin/console debug:router
- Advanced routing

11. TWIG
Pass values to twig
Print values
Including file
composer require
assets

12. DEPENDENCY INJECTION
- Dependency injection is a design pattern whose
purpose is to: improve the testability, simplify code
- Composition VS Inheritance
- Autowiring

13. TIPS
- Profiler
- Bundles
- doctrine
- monolog
- fosrest
- fosuser
- guzzle
- jms serializer
- nelmio
- ramsey - uuid
- aws
- elastic search
- Form
- Commands bin/console
