    Howto deploy Lumen projects within a subfolder (on a shared hoster)

For Lumen (5.0.8) (Laravel Components 5.0.*)
Use Case: Deploying Lumen App to Shared Hoster such that it can be called via domain.tld/lumenapp/...
Folder Layout


Rename public to desired name (new root folder, for example lumenapp)
Move everything else into a new folder, named e.g. project_src

Path Changes


In lumenapp/index.php, change the $app = ... line to

    $app = require __DIR__.'/../project_src/bootstrap/app.php';


In project_src/vendor/laravel/lumen-framework/Application.php change the dispatch method (line ~1027) to remove the lumenapp part from requests (the part from $rootFolder = ...):

    public function dispatch($request = null)
    {
        if ($request) {
            $this->instance('Illuminate\Http\Request', $request);
            $this->ranServiceBinders['registerRequestBindings'] = true;

            $method = $request->getMethod();
            $pathInfo = $request->getPathInfo();
        } else {
            $method = $this->getMethod();
            $pathInfo = $this->getPathInfo();
        }

        try {

            //Get the root folder from .env file
            //Strap this root folder from the route ($pathInfo)
            $rootFolder = '/'.env('ROOT_FOLDER', 'root');
            if(starts_with($pathInfo, $rootFolder))
            {
                $exp = explode('/',$pathInfo);
                unset($exp[0]);
                unset($exp[1]);
                $pathInfo = '/'.implode('/',$exp);
            }

            if (isset($this->routes[$method.$pathInfo])) {
                return $this->handleFoundRoute([true, $this->routes[$method.$pathInfo]['action'], []]);
            }

            return $this->handleDispatcherResponse(
                $this->createDispatcher()->dispatch($method, $pathInfo)
            );
        } catch (Exception $e) {
            return $this->sendExceptionToHandler($e);
        }
    }

Environment File

The mentioned dispatch method looks for the folder name in the .env File, so define it there: ROOT_FOLDER=lumenapp
.htaccess

This is what my .htaccess within the lumenapp (former public) folder looks like:
RewriteEngine On

RewriteBase /

# Redirect Trailing Slashes...

RewriteRule ^(.*)/$ /$1 [L,R=301]

# Handle Front Controller...
RewriteCond $1 !^(index\.php|images|quotes|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ quotes/index.php/$1 [L,QSA]

Assets

Referenced images, CSS files in the lumenapp directory need the new path (\lumenapp\css\...) or some extra handling.
