Stack middleware for handling Javascript Unpoly Framework requests.
You can install the package via Composer.
composer require webstronauts/unpolyYou can manually decorate the response with the Unpoly object.
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Webstronauts\Unpoly\Unpoly;
// ...
$unpoly = new Unpoly();
$unpoly->decorateResponse($request, $response);You can decorate the response using the supplied Stack middleware.
use Webstronauts\Unpoly\StackUnpoly;
use Webstronauts\Unpoly\Unpoly;
// ...
$app = new StackUnpoly($app, new Unpoly());To use the package with Laravel, you'll have to wrap it around a middleware instance.
<?php
namespace App\Http\Middleware;
use Closure;
use Webstronauts\Unpoly\Unpoly as UnpolyMiddleware;
class Unpoly
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$response = $next($request);
(new UnpolyMiddleware)->decorateResponse($request, $response);
return $response;
}
}Now use this middleware as described by the Laravel documentation.
<?php
// Within App\Http\Kernel class...
protected $routeMiddleware = [
// ...
'unpoly' => \App\Http\Middleware\Unpoly::class,
];Whenever a form is submitted through Unpoly, the response is returned as JSON by default. This is because Laravel returns JSON formatted response for any request with the header X-Requested-With set to XMLHttpRequest. To make sure the application returns an HTML response for any validation errors, overwrite the convertValidationExceptionToResponse method in your App\Exceptions\Handler class.
<?php
// Within App\Exceptions\Handler class...
protected function convertValidationExceptionToResponse(ValidationException $e, $request)
{
if ($e->response) {
return $e->response;
}
return $request->expectsJson() && ! $request->hasHeader('X-Up-Target')
? $this->invalidJson($request, $e)
: $this->invalid($request, $e);
}If your Laravel session expires and a user attempts to navigate or perform an operating on the page using Unpoly, an abrupt JSON error response will be displayed to the user:
{'error': 'Unauthenticated.'}
To prevent this, create your own Request and extend Laravel's built-in Illuminate\Http\Request, and override the expectsJson method:
namespace App\Http;
use Illuminate\Http\Request as BaseRequest;
class Request extends BaseRequest
{
public function expectsJson()
{
if ($this->hasHeader('X-Up-Target')) {
return false;
}
return parent::expectsJson();
}
}Then, navigate to your public/index.php file, and update the usage:
// From...
$response = $kernel->handle(
$request = Illuminate\Http\Request::capture()
);
// To...
$response = $kernel->handle(
$request = App\Http\Request::capture()
);Now when a user session expires, the <body> of your page will be replaced with your login page, allowing users to sign back in without refreshing the page.
