Title: Setting the Content-Type Header for Laravel Views as "application/javascript"
Introduction
The Laravel framework allows developers to easily generate views using the Blade engine, but it can sometimes be challenging to modify the output content type. This article will discuss how you can make Laravel return a view's Content-Type header as "application/javascript." By doing so, your external websites can better handle the dynamic JavaScript file from Laravel without showing any browser warnings.
Main Body
1. Understanding the problem: In your given example, the issue is that the output content type for your embedded view is being rendered as "text/html" by default. This causes browsers like Chrome to display warnings about resources with mismatched MIME types (e.g., Resource interpreted as Script but transferred with MIME type text/html).
2. Approaches to solve this issue: There are several ways you can tackle this problem, such as using headers(), adding a Content-Type response header in your controller, or defining a custom view class for your embedded views that extends the default Laravel BladeView class and adds the desired Content-Type header.
3. Using headers() in the view: You can try setting the Content-Type header in your view as follows:
<?php
header('Content-Type: application/javascript; charset=UTF-8', true);
?>(function(jQuery) {
// append stylesheets to <head>
var file;
// ...
})(jQuery);
{
// ...
return View::make('embedded')->with('foo', $foo)
->setResponse([
'headers' => [
'Content-Type' => 'application/javascript; charset=UTF-8',
],
]);
}
namespace App\Http\Views;
use Illuminate\View\View;
class EmbeddedView extends View
{
/**
* Set the response headers.
*
* @param \Illuminate\Http\ResponseInterface $response
* @return void
*/
public function setHeaders($response)
{
parent::setHeaders($response);
return $response->headers->set('Content-Type', 'application/javascript; charset=UTF-8');
}
}
