laravel provides handy facade artisan commands.

just use artisan::call('your-command') need.

example:

route::get('artisan-command/{command}', function($command) {     artisan::call($command); }); 

your url looks this: http://yourhost.com/artisan-command/db:seed

more specific use-case:

route::get('vendor-publish/{provider}', function($provider) {     artisan::call('vendor:publish', ['provider' => $provider]); }); 

and url: http://yourhost.com/vendor-publish/tymon\jwtauth\providers\jwtauthserviceprovider
