I have a project built with slim 3 and is working as expected (http://localhost/slimapp/). Now what I want to do is in one of the subfolder run an Angular2 application. But as I try to access the subfolder (http://localhost/slimapp/angularapp/) via browser it is redirected to index.php of slim3, which is quite obvious. What I want to achieve is when I visit http://localhost/slimapp/angularapp/ this URL should not be redirected through slim3 .htaccess and it should run an angular application.
So far I tried in .htaccess is add
RewriteRule ^angularapp($|/) - [L,NC]
This results in 404 not found a page for http://localhost/slimapp/angularapp/.
Any help is much appreciated. Thanks
