0 likes704 views
The document discusses the development of Flow3, an application framework crucial for TYPO3's evolution, highlighting its rich history, architecture, and coding practices. Key features include a robust MVC structure, dependency injection, and built-in content persistence, promoting efficient web application development. The presentation outlines the framework's requirements, capabilities, and future plans, aiming to inspire developers to engage with TYPO3 and Flow3 for enhanced web solutions.
![The FLOW3 experience
Flow [fl!] The mental state of operation in which the person is fully immersed in
what he or she is doing by a feeling of energized focus, full involvement, and
success in the process of the activity. Proposed by positive psychologist Mihály
Csíkszentmihályi, the concept has been widely referenced across a variety of fields.
FLOW3 [fl!'three] The application framework which takes care of all hassle and lets
you play the fun part.

- 2. The History of FLOW3 (short version)
- 3. The Long History of TYPO3 Since 1998 33 core members committed 500.000 lines of code resulting in a code base of 300.000 lines today
- 4. TYPO3 today TYPO3 v4 is nearly feature complete Grown architecture, few unit tests Fundamental changes are risky Often used as an application framework - but was designed as a CMS Fluent Development with FLOW3 Inspiring people to share
- 5. TYPO3 tomorrow? Fluent Development with FLOW3 Inspiring people to share

- 20. Getting Started Grant File Permissions The webserver needs read access for all files of the distribution and write access in the Public and Data directory On Linux / Mac just call sudo ./fixpermissions.sh On legacy operating systems: ask your system administrator Fluent Development with FLOW3 Inspiring people to share
- 21. Getting Started Create a package In order to create a new package, just create a new folder within the Packages directory. Fluent Development with FLOW3 Inspiring people to share
- 22. Getting Started Create a Default Controller Create a subfolder in your package: Classes/Controller/ Create the controller class file: <?php declare(ENCODING = 'utf-8'); namespace F3MyPackageController; class DefaultController extends F3FLOW3MVCControllerActionController { ! public function indexAction() { ! ! return 'Hello World!'; ! } } ?> Fluent Development with FLOW3 Inspiring people to share
- 23. Bootstrap Fluent Development with FLOW3 Inspiring people to share
- 24. Bootstrap Public/index.php This file is the default main script It launches FLOW3 in the Production context The webserver's web root should point to the Public directory define('FLOW3_PATH_PUBLIC', str_replace('', '/', __DIR__) . '/'); require(FLOW3_PATH_PUBLIC . '../Packages/FLOW3/Classes/F3_FLOW3.php'); $framework = new F3FLOW3(); $framework->run(); Fluent Development with FLOW3 Inspiring people to share
- 25. Bootstrap Public/index_dev.php This script is used for development It launches FLOW3 in the Development context More scripts like this can be created for additional contexts define('FLOW3_PATH_PUBLIC', str_replace('', '/', __DIR__) . '/'); require(FLOW3_PATH_PUBLIC . '../Packages/FLOW3/Classes/F3_FLOW3.php'); $framework = new F3FLOW3('Development'); $framework->run(); Fluent Development with FLOW3 Inspiring people to share
- 26. Model - View - Controller Fluent Development with FLOW3 Inspiring people to share
- 27. MVC Key Features Powerful Request-Response mechanism, based on Front Controller and Dispatcher Very convenient controllers and views Supports multiple template engines Sophisticated, easy to configure routing Built-in validation and default security REST support Fluent Development with FLOW3 Inspiring people to share
- 28. MVC Model Types Active Record Domain Model Model of / wrapper for a Model of a domain which consists of database table row data and behaviour is responsible for persistence doesn't know about persistence mixes infrastructure concerns with model doesn't know about infrastructure quick to implement without a framework clean and easy to use if framework supports it Fluent Development with FLOW3 Inspiring people to share

- 31. Persistence Fluent Development with FLOW3 Inspiring people to share
- 32. Persistence JSR-283 based Content Repository Defines a uniform API for accessing content repositories A Content Repository is a kind of object database for storage, search and retrieval of hierarchical data provides methods for versioning, transactions and monitoring TYPO3CR is the first working port of JSR-170 / JSR-283 Karsten Dambekalns is member of the JSR-283 expert group Fluent Development with FLOW3 Inspiring people to share
- 33. Persistence Transparent Persistence Explicit support for Domain-Driven Design Class Schemata are defined by the Domain Model class No need to write an XML or YAML schema definition No need to define the database model and object model multiple times at different places Automatic persistence in the JSR-283 based Content Repository Legacy data sources can be mounted Fluent Development with FLOW3 Inspiring people to share
- 34. Components Fluent Development with FLOW3 Inspiring people to share
- 35. Components Component Dependencies Components seldomly come alone Components depend on other components which depend on other components which ... Problem: Components explicitly refer to other components: $phoneBookManager = new PhoneBookManager Fluent Development with FLOW3 Inspiring people to share
- 36. Components Dependency Injection A component doesn't ask for the instance of another component but gets it injected This methodology is referred to as the "Hollywood Principle": "Don't call us, we'll call you" Enforces loose coupling and high cohesion Makes you a better programmer Fluent Development with FLOW3 Inspiring people to share
- 37. Components Autowiring FLOW3 tries to autowire constructor arguments and arguments of inject* methods The type of the component to be injected is determined by the argument type (type hinting) Autowiring does not work with Setter Injection through regular setters (set* methods) Dependencies are only autowired if no argument is passed explicitly Fluent Development with FLOW3 Inspiring people to share
