This bundle enables you to easily proxy requests. It stands as a gateway between your API and a number of external services.

About package

This package will help you create an api gateway.

Install

composer require demroos/api-gateway-bundle

Enable bundle

in config/bundles.php

<?php

return [
    // other bundles,                            
    Demroos\Bundle\ApiGatewayBundle\ApiGatewayBundle::class => ['all' => true]    
];

Config

Config endpoints

in api_gateway.yml

api_gateway:
  config:
    headers:
      - 'Content-Type'
  endpoints:
    api_example:
      url: '/api/example'
      method: 'POST'
      config:
        url: 'https://example.com/api/example'
        method: 'POST'

Load endpoint from loader

• You create a service that implements the EndpointLoaderInterface interface
• You add tag api_gateway.endpoint_loader for this service

<?php
namespace App\Routing;

use Demroos\Bundle\ApiGatewayBundle\Contracts\EndpointLoaderInterface;
use Demroos\Bundle\ApiGatewayBundle\Endpoint;

class ExampleEndpointLoader implements EndpointLoaderInterface
{
    public function load(): array
    {
        $endpoints = [];

        $endpoint = new Endpoint(
            'api_example',
            '/api/example',
            'POST'
        );

        $endpoints[] = $endpoint;

        return $endpoints;
    }
}

in config/services.yaml

services:
  App\Routing\ExampleEndpointLoader:
    tags: [api_gateway.endpoint_loader]

Config client factory

in api_gateway.yml

api_gateway:
  client_factory:
    #service: id_service_for_use_as_client_factory
    config:
      http_errors: false
