- [Symfony Tutorials] : How to create a restAPI using symfony ?
---- to run project : docker compose up --pull always -d --wait OR use vscode extension Docker

- REST API (Representational State Transfer API)

1. composer require api

2. php bin/console make:entity Product --api-resource
-(name (string) description (text) price (float) createdAt (datetime_imm null)

3. php bin/console make:migration && php bin/console doctrine:migrations:migrate

4. php bin/console debug:router

5. Change in config/routes/api_plataform.yaml
- prefix : /api/v1

6. Change in config/packages/api_plataform.yaml
formats:
jsonld: ['application/ld+json']
json: ['application/json'] # Add support for JSON
7. On POSTMAN create new product, check products (header with application/ld+json or application/ld+json)

8. Test again create a product and check on browser too

9. On postman, edit a product using patch request with header : Content-Type : application/merge-patch+json

10. Check diffs between https://localhost/api/v1/products.json and https://localhost/api/v1/products.jsonld

11. Check https://localhost/api/v1 for API auto generated documentation

12. Add this to model to handle errors on missing fields :
(use Symfony\Component\Validator\Constraints as Assert;)
#[Assert\NotNull(message: "Price cannot be null.")]
#[Assert\Positive(message: "Price must be a positive number.")]

13. That's it, your simple restAPI is working

By Hugo Resende !!!!!!

1. First let's make entity Product

- php bin/console make:entity Product
- php bin/console make:migration && php bin/console doctrine:migrations:migrate
- php bin/console make:controller API\\ProductAPIController

2. Change API controller index function :
#[Route('api/v1/product', name: 'api_product')]
public function index(ProductRepository $productRepository): JsonResponse
{
$products = $productRepository- findAll();
return $this- json($products);
}
8. Make a ProductAPIController, delete the generated template (we don't need it atm) and index function on controller

9. Create update function :
- #[Route('/api/products/{id}', name: 'api_product_update')]
public function update(Product $product, Request $request, EntityManagerInterface $entityManager, SerializerInterface $serializer): Response
{
$requestData = $request- getContent();
$updatedProduct = $serializer- deserialize($requestData, Product::class, 'json');

$product- setName($updatedProduct- getName());
$product- setPrice($updatedProduct- getPrice());

$entityManager- flush();

return new Response('Product updated!', 200);
}
