3 likes2,284 views
The document summarizes the state of the Lithium framework. It discusses project and community stats including contributors and issues closed. It outlines progress on the roadmap including new features like encrypting and signing cookies, nesting routes, and error handling. Upcoming features mentioned are HTTP service classes, filtering and sorting collections, and schema and multibyte classes. Community plugins are highlighted and tips and tricks are provided before opening for Q&A.

The State of Lithium
- 1. THE STATE OF LITHIUM li3_nyc::init() // 2012-02-07
- 2. SPONSORS
- 3. AGENDA • State of the framework • New features • Upcoming features • Community plugins • Library management & The Lab • Tips & tricks • Q&A / Demos!
- 4. STATE OF THE FRAMEWORK
- 5. PROJECT & COMMUNITY STATS • ~130 plugin repositories on GitHub • 350+ commits from 40+ contributors since 0.10 • 60+ commits to the manual since 0.10 • Closed 250+ issues since moving to GitHub • 175 pull requests submitted since moving to GitHub
- 6. ROADMAP PROGRESS • Cookie signing / encryption • CSRF protection • Error Handling • Manual / automatic SQL result mapping • Relationship support
- 7. NEW FEATURES
- 8. ENCRYPT & SIGN COOKIES Session::config(array('default' => array( 'adapter' => 'Cookie', 'strategies' => array( 'Hmac' => array('secret' => '$f00bar$'), 'Encrypt' => array('secret' => '$f00bar$') ) )));
- 9. NEST ROUTES Router::connect("/admin/{:args}", array('admin' => true), array( 'continue' => true )); Router::connect("/{:locale:en|de|jp}/{:args}", array(), array( 'continue' => true )); Router::connect("/{:args}.{:type}", array(), array( 'continue' => true ));
- 10. HANDLE ERRORS $method = array(Connections::get('default'), 'read'); ErrorHandler::apply($method, array(), function($error, $params) { $queryParams = json_encode($params['query']); $msg = "Query error: {$error['message']}"; Logger::warning("{$msg}, data: {$queryParams}"); return new DocumentSet(); });
- 11. PROTECT FORMS <?=$this->form->create(); ?> <?=$this->security->requestToken(); ?> <?=$this->form->field('title'); ?> <?=$this->form->submit('Submit'); ?> <?=$this->form->end(); ?> public function add() { if ( $this->request->data && !RequestToken::check($this->request) ) { // Badness!! } }
- 13. HTTP SERVICE CLASSES $http = new Http(array( ... 'methods' => array( 'do' => array('method' => 'post', 'path' => '/do') ) )); POST /do HTTP/1.1 $response = $http->do(new Query(array( … 'data' => array('title' => 'sup') ))); title=sup // var_dump($response->data());
- 14. FILTER / SORT COLLECTIONS $users->find(array("type" => "author"))->sort("name"); $users->first(array("name" => "Nate"));
- 15. MULTIBYTE CLASS • Supports mbstring, intl, iconv & (womp, womp) plain PHP • Only one method right now: strlen() • More would be good… open a pull request
- 16. SCHEMA CLASS • Arbitrary data types • Arbitrary handlers • Example: hash modified passwords before writing • Other example: JSON en/decode arbitrary data for MySQL
- 17. PLUGINS
- 18. LI3_DOCTRINE2 Connections::add('default', array( 'type' => 'Doctrine', • Works with Lithium stuff: 'driver' => 'pdo_mysql', 'host' => 'localhost', 'user' => 'root', • Connections 'password' => 'password', 'dbname' => 'my_db' )); • Authentication /** * @Entity * @Table(name="users") • Forms */ class User extends li3_doctrine2modelsBaseEntity { /** * @Id • Sessions * @GeneratedValue * @Column(type="integer") */ private $id; • Validation /** * @Column(type="string",unique=true) */ private $email; ... }
- 19. LI3_FILESYSTEM use li3_filesystemstorageFileSystem; FileSystem::config(array( 'default' => array( 'adapter' => 'File' ), 'ftp' => array( 'adapter' => 'Stream', 'wrapper' => 'ftp', 'path' => 'user:password@example.com/pub/' } )); FileSystem::write('default', '/path/to/file', $data);
- 20. LI3_ACCESS Access::config(array( 'asset' => array( 'adapter' => 'Rules', 'allowAny' => true, 'default' => array('isPublic', 'isOwner', 'isParticipant'), 'user' => function() { return Accounts::current(); }, 'rules' => array( 'isPublic' => function($user, $asset, $options) { ... }, 'isOwner' => function($user, $asset, $options) { ... }, 'isParticipant' => function($user, $asset, $options) { ... } ) ) ... );
- 21. LI3_ACCESS Access::config(array( ... 'action' => array( 'adapter' => 'Rules', 'default' => array('isPublic', 'isAuthenticated'), 'allowAny' => true, 'user' => function() { return Accounts::current(); }, 'rules' => array( 'isPublic' => function($user, $request, array $options) { ... }, 'isAuthenticated' => function($user, $request, array $options) { ... }, 'isAdmin' => function($user, $asset, $options) { ... } ) ) );
- 22. LI3_ACCESS Dispatcher::applyFilter('_call', function($self, $params, $chain) { $opts = $params['params']; $request = $params['request']; $ctrl = $params['callable']; if ($access = Access::check('action', null, $ctrl, $opts)) { // Reject } if ($access = Access::check('action', null, $ctrl, array('rules' => 'isAdmin') + $opts)) { // Reject } return $chain->next($self, $params, $chain); }); class PostsController extends Base { public $publicActions = array('index', 'view'); }
- 24. THE LAB
- 25. TIPS & TRICKS
- 26. RETURN ON REDIRECT class PostsController extends Base { public function view($post) { if (!$post) { $this->redirect("Posts::index"); } // Herp derp } }
- 27. FAT FILTERS == BAD Dispatcher::applyFilter('run', function($self, $params, $chain) { // Herp // Derp // Herp // Derp // Herp // Derp // Herp // Derp // Herp // Derp // Herp (repeat x100) });
- 28. DEFINE YOUR SCHEMA! { count: 5, ... } ... { count: "5", ... }
- 29. DON’T FEAR THE SUBCLASS class Base extends lithiumdataModel { public function save($entity, $data = null, array $options = array()) { if ($data) { $entity->set($data); } if (!$entity->exists()) { $entity->created = new MongoDate(); } $entity->updated = new MongoDate(); return parent::save($entity, null, $options); } } class Posts extends Base { ... }
- 30. QUICK & DIRTY ADMIN Dispatcher::config(array('rules' => array( 'admin' => array( 'action' => 'admin_{:action}' ) ))); class PostsController extends Base { Router::connect( public function admin_index() { '/admin/{:args}', ... array('admin' => true), } array('continue' => true) ); public function index() { ... } }
- 31. Q&A / DEMOS
- 32. THANKS!
