Let’s do some comparisons

Slide 21

Slide 21 text

Comparison MVC Design Lightweight Fast Excellent Docs Compatibility Technical Debt

Slide 22

Slide 22 text

Comparison MVC Design Heavy but has Silex Slow-ish Complex Good Docs Modular Backed by SensioLabs

Slide 23

Slide 23 text

Beyond MVC Design Easy to get started Consistent/Stable Fast Excellent Docs Threw out previous framework ideas and started over Comparison

Slide 24

Slide 24 text

OK, I’ll try it. How do I get started?

Slide 25

Slide 25 text

Download Composer Based Install $ composer create-project laravel/laravel --prefer-dist

Slide 26

Slide 26 text

Structure Commands Providers Controller || Route || Both Middleware Services Views Model / Repository / FLEXIBILITY

Slide 27

Slide 27 text

Routes

Slide 28

Slide 28 text

Routes Create routes at: routes/web.php routes/api.php Web = web middleware API = api middleware App\Providers\RouteServiceProvider to add new route ﬁles

Slide 29

Slide 29 text

Routes What methods are available: Route::get(); Route::post(); Route::put(); Route::patch(); Route::delete(); Route::any(); //all of the above

Slide 30

Slide 30 text

Routes Register multiple verbs for a single route: Router::match([‘get’, ‘post’], ‘/’, function(){ //this will run for both GET and POST });

Slide 31

Slide 31 text

Routes routes/web.php Route::get('/', function(){ echo ‘Boom!’; });

Slide 32

Slide 32 text

Testing

Slide 33

Slide 33 text

Testing Runs all tests located at: /tests/ $ php artisan test

Slide 34

Slide 34 text

Testing routes/web.php Route::get('/', function(){ echo ‘Boom!’; });

Slide 35

Slide 35 text

Testing /tests/ExampleTest.php Test it! Test it good! class ExampleTest extends TestCase { function testBasicExample() { $this->visit('/') ->see(‘Boom!');

Slide 36

Slide 36 text

Testing $ php artisan test Run it! PHPUnit 3.6.10 by Sebastian Bergmann. Conﬁguration read from ... Time: 0 seconds, Memory: 6.25Mb OK (1 test, 1 assertion) Output

Slide 37

Slide 37 text

API?

Slide 38

Slide 38 text

What about an API? Routes to the rescue!

Slide 39

Slide 39 text

API routes/api.php Route::get(‘user/{id}’, function($id){ return json_encode([ ‘user‘ => User::ﬁnd($id), ‘success‘ => true ]); });

Slide 40

Slide 40 text

API routes/api.php Route::get(‘user/{id}’, function($id){ return [ ‘user‘ => User::ﬁnd($id), ‘success‘ => true ]; });

Slide 41

Slide 41 text

API App\Providers\RouteServiceProvider protected function mapApiRoutes() { Route::group([ 'middleware' => ['api', 'auth:api'], 'namespace' => $this->namespace, 'preﬁx' => 'api', ], function ($router) { require base_path('routes/api.php'); });

Slide 42

Slide 42 text

Slide 43

Slide 43 text

API /tests/api/UserTest.php class UserTest extends TestCase { public function testGetUser() { $this->get(‘/api/user/1’) ->seeJson([ ‘success‘ => true ]);

Slide 44

Slide 44 text

Controllers

Slide 45

Slide 45 text

Controllers OK, routes are cool and all, but what if I want to use controllers?

Slide 46

Slide 46 text

Controllers routes/web.php Route::post('status', 'StatusController@create'); class StatusController extends Controller { public function create(Request $request) { … app/Http/controllers/StatusController.php

Slide 47

Slide 47 text

Shit just got real

Slide 48

Slide 48 text

Middleware

Slide 49

Slide 49 text

Middleware Route Filters BETTER FASTER STRONGER Middleware!

Slide 50

Slide 50 text

Middleware Popular Uses: Auth ACL Session Caching Debug Logging Analytics Rate Limiting

Slide 51

Slide 51 text

Middleware Route::post('status', ‘StatusController@create’, [‘middleware’ => ‘auth’] );

Slide 52

Slide 52 text

Middleware Route::post('status', ‘StatusController@create’, [‘middleware’ => [ ‘ﬁrst’, ‘second’, ‘third’, ]] );

Slide 53

Slide 53 text

Middleware class AjaxMiddleware implements Middleware { public function handle($request, Closure $next) { if (!$request->ajax()) return response('Unauthorized.', 401); return $next($request); }

Slide 54

Slide 54 text

Middleware Groups for DRY routing: Route::group(['middleware' => 'auth'], function(){ Route::get('/statuses', function(){ … }); …

Slide 55

Slide 55 text

Database

Slide 56

Slide 56 text

Database Query Builder Eloquent ORM Migrations Seeding

Slide 57

Slide 57 text

Query Builder Simple and Easy to Understand Used extensively by Eloquent ORM

Slide 58

Slide 58 text

Query Builder $user = DB::table('statuses') ->where(‘email’, '[email protected]’) ->ﬁrst(); Query Row by Email

Slide 59

Slide 59 text

Query Builder $id = DB::table('statuses') ->insertGetId([ ‘user_id' => 1, 'email' => ‘[email protected]', 'text' => ‘Vegas Baby! #zendcon’, ]); Insert & Get ID

Slide 60

Slide 60 text

Eloquent ORM Simple Expressive Efﬁcient

Slide 61

Slide 61 text

Eloquent ORM use Illuminate\Database\Eloquent\Model; class Status extends Model { } Deﬁne an Eloquent model

Slide 62

Slide 62 text

Eloquent ORM $status = App\Status::where(‘user_id’, 1) ->ﬁrst(); Simple query

Slide 63

Slide 63 text

Eloquent ORM $statuses = App\Status::where(‘views', '>', 100) ->get(); Slightly more advanced query

Slide 64

Slide 64 text

Eloquent ORM Relationships class Status extends Model { public function user() { return $this->belongsTo(‘App\User'); } } App\Status::ﬁnd(1)->user->email; Retrieve Status Creator Email

Slide 65

Slide 65 text

Eloquent ORM Normal Usage $statuses = App\Status::all(); foreach ($statuses as $status) echo $status->user->email;

Slide 66

Slide 66 text

Eloquent ORM Normal Usage $statuses = App\Status::all(); foreach ($statuses as $status) echo $status->user->email; SELECT * FROM "statuses" foreach result { SELECT * FROM "users" WHERE "id" = 1 } 100 statuses = 101 queries

Slide 67

Slide 67 text

WTF!? ORMs Suck!

Slide 68

Slide 68 text

Eloquent ORM $statuses = App\Status::with(‘user’)->get(); foreach ($statuses as $status) echo $status->user->email; Eager Loading FTW!

Slide 69

Slide 69 text

Eloquent ORM $statuses = App\Status::with(‘user’)->get(); foreach ($statuses as $status) echo $status->user->email; 100 statuses = 2 queries SELECT * FROM "statuses" SELECT * FROM "users" WHERE "id" IN (1, 2, 3, 4, 5, ...) Eager Loading FTW!
