Hello, Worlds!

🌐 "Hello, World!" (super simple, just minimal) examples of doing things in Siler.

Functional

My favorite ❤λ

php -S localhost:8000 -t 00-functional

use Siler\Functional as λ; // Just to be cool, don't use non-ASCII identifiers ;)
use Siler\Route;

Route\get('/', λ\puts('Hello, World!'));

JSON

The Response\json function will automatically add Content-type: application/json in the response headers.

php -S localhost:8000 -t 01-json

use Siler\Route;
use Siler\Http\Response;

Route\get('/', fn() => Response\json(['message' => 'Hello, World!']));

GraphQL

Install peer-dependency:

composer require webonyx/graphql-php

Schema-first

type Query {
    hello: String
}

use Siler\Route;
use Siler\GraphQL;

$type_defs = file_get_contents(__DIR__ . '/schema.graphql');
$resolvers = [
    'Query' => [
        'hello' => fn ($root, $args, $context, $info) => 'Hello, World!'
    ]
];

$schema = GraphQL\schema($type_defs, $resolvers);

Route\post('/graphql', fn() => GraphQL\init($schema));

Code-first

Peer-dependency:

composer require doctrine/annotations

Then:

/**
 * @\Siler\GraphQL\Annotation\ObjectType()
 */
final class Query
{
    /**
     * @\Siler\GraphQL\Annotation\Field()
     */
    static public function hello($root, $args, $context, $info): string
    {
        return 'Hello, World!';
    }
}

use Siler\GraphQL;
use Siler\Route;

$schema = GraphQL\annotated([Query::class]);

Route\post('/graphql', fn() => GraphQL\init($schema));

Object type name will be guessed from class name, same for field name, and it's return type (i.e.: PHP string scalar === GraphQL String scalar).
