README
The PHP reference implementation of BLEST (Batch-able, Lightweight, Encrypted State Transfer), an improved communication protocol for web APIs which leverages JSON, supports request batching by default, and provides a modern alternative to REST. It includes examples for Leaf, Slim, and OpenSwoole.
To learn more about BLEST, please visit the website: https://blest.jhunt.dev
For a front-end implementation in Vue, please visit https://github.com/jhuntdev/blest-vue
Features
- Built on JSON - Reduce parsing time and overhead
- Request Batching - Save bandwidth and reduce load times
- Compact Payloads - Save even more bandwidth
- Single Endpoint - Reduce complexity and facilitate introspection
- Fully Encrypted - Improve data privacy
Installation
Install BLEST PHP with Composer.
composer require blest/blest
Usage
The App
class of this library has an interface similar to Leaf or Slim. It also provides a Router
class with a handle
method for use in an existing PHP application and an HttpClient
class with a request
method for making BLEST HTTP requests.
require __DIR__ . '/vendor/autoload.php'; use BLEST\BLEST\App; // Instantiate an app (or use functional mode: app()->...) $app = new App(); // Create some middleware (optional) $authMiddleware = function($body, $context) { if (isset($context['headers']['auth']) && $context['headers']['auth'] === 'myToken') { $context['user'] = [ // user info for example ]; } else { throw new Exception('Unauthorized'); } }; $app->use($authMiddleware); // Create a route controller $greetController = function($body, $context) { return [ 'greeting' => 'Hi, ' . $body['name]' . '!' ]; }; $app->route('greet', $greetController); // Run the app $app->run();
Router
This example uses Slim, but you can find examples with other frameworks here.
require __DIR__ . '/vendor/autoload.php'; use Psr\Http\Message\ResponseInterface as Response; use Psr\Http\Message\ServerRequestInterface as Request; use Slim\Middleware\BodyParsingMiddleware; use Slim\Factory\AppFactory; use BLEST\BLEST\Router; // Instantiate the router $router = new Router(); // Create some middleware (optional) $authMiddleware = function($body, $context) { if (isset($context['headers']['auth']) && $context['headers']['auth'] === 'myToken') { $context['user'] = [ // user info for example ]; } else { throw new Exception('Unauthorized'); } }; $router->use($authMiddleware); // Create a route controller $greetController = function($body, $context) { return [ 'greeting' => 'Hi, ' . $body['name]' . '!' ]; }; $router->route('greet', $greetController); // Create the Slim app $app = AppFactory::create(); // Parse request body $app->addBodyParsingMiddleware(); // Listen for POST requests on root URL ("/") $app->post('/', function (Request $request, Response $response) use ($requestHandler) { $body = $request->getParsedBody(); $context = [ 'headers' => $request->getHeaders() ]; [$result, $error] = $router->handle($body, $context); if ($error) { $response->getBody()->write(json_encode($error)); return $response->withHeader('Content-Type', 'application/json')->withStatus(500); } else { $response->getBody()->write(json_encode($result)); return $response->withHeader('Content-Type', 'application/json')->withStatus(200); } }); // Run the app $app->run();
HttpClient
require __DIR__ . '/vendor/autoload.php'; use BLEST\BLEST\HttpClient; // Create an HTTP client $client = new HttpClient('http://localhost:8080', [ 'httpHeaders' => [ 'Authorization' => 'Bearer token' ] ]); // Use the client to make a request $client->request('greet', ['name' => 'Steve'], ['auth' => 'myToken']);
