Bridging Laravel 5 and Lumen with Guzzle

laravel-routes.php

<?php

// Obviously, you would build up the request somewhere other than a route...

Route::get('/api', function()
{

    $client   = new \GuzzleHttp\Client();
  
    $response = $client->get('http://path/to/api');
  
    return $response->getBody();
  
});

// Visiting '/api' would return "Hello World" from Lumen!

lumen-routes.php

<?php

$app->get('/text', function() 
{

	return 'Hello World';
	
});

// You may need to enable CORS header if Laravel and Lumen are on separate servers!

$app->get('/json', function() use ($app) 
{

    return response()->json([
        "foo" => 'bar'
    ])
    ->header('Access-Control-Allow-Origin', '*');

});
