Converting to Drupal

Hi Guys, 

I'm converting my D7 website to D8 and in D7 js file I'm calling a ajax request and url is: 

url:  Drupal.settings.basePath + Drupal.settings.pathPrefix +  'system/ajax'

And I have already converted this line as:

url:  drupalSettings.path.baseUrl + drupalSettings.path.pathPrefix + 'system/ajax'

But it is showing 404 not found on the console.

Hi Guys, 

I'm converting my Drupal 7 project to Drupal 8 and in Drupal 7 we are using Drupal.settings.basePath and basePath is set in drupal_add_js function which is deprecated in Drupal 8. 

So, How can I use this basePath in Drupal 8 js ?

Hi Guys,

It is possible to call a twig file after clicking any button in Drupal 8?
if yes then how can I achieve this ?

I'd like to use drush. It needs to run in the drupal container. There's also a drush docker repo. But I have no clue how to make it available whithin the drupal container. It's my first docker and drupal project, so maybe I'm getting things completely wrong.

How can I use drush with this drupal docker image? https://hub.docker.com/_/drupal/ Is it possible to manage it with docker-compose? Maybe extending the drupal container?

This is my docker-compose.yml:

I am adding this new element but #theme_wrapper is not working, only title is showing button is not showing.

Hi Guys,

Please help.

Thanks for advance.
