Symfony 4: A quick Demo

Creating a new Project

The first step is to create a project. Currently, this needs to be done via composer create-project. We might release a tool to bootstrap a project faster.

composer create-project "symfony/skeleton:^3.3" demo
cd demo
git init
git add .
git commit -m "initial set of files"
###> symfony/framework-bundle ###
###< symfony/framework-bundle ###
return [
'Symfony\Bundle\FrameworkBundle\FrameworkBundle' => ['all' => true],
composer req webserver
composer req cli
composer req cli:next
composer rem cli
composer req admin
<?phpnamespace App\Entity;use Doctrine\ORM\Mapping as ORM;/**
* @ORM\Entity
* @ORM\Table(name="product")
class Product {
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
public $id;
* @ORM\Column(type="string", length=100)
public $name;
* @ORM\Column(type="decimal", scale=2)
public $price;
* @ORM\Column(type="text")
public $description;
###> doctrine/doctrine-bundle ###

./bin/console doctrine:database:create
./bin/console doctrine:schema:update --force
