Drupal 8.x

I have some code that runs on an admin page controller. So if I do $route_match = \Drupal::routeMatch(); then it relates to that admin page. However, I want to Temporarily change the value of \Drupal::routeMatch() so that it uses the path of a node (for example node/1).

With Drupal 7 I could simply change $_GET['q'] = 'node/1', for example, do my logic and switch it back to the original path afterwards.

I would like to know if it's possible to install multiple arbitrary modules with a single composer command, and if yes, how to do it please

I have a view

It used to be called 'page_1'
It is now called 'c_page'

I have created a template called 

'node--view--branch-list--c-page.html' to render this view

I created a module for my marketplace (several stores and owners). It displays a required checkbox, in the purchase funnel. With a link to the general conditions of sale which are rendered in a modal window.

I want to display the rendered entity of the store with the CGV display mode.

Can you reply with the correct code ? Thank you

If we set the the content authoring editors to include the "Media Library" button then it is very easy to upload and insert images onto nearly any visible entity (custom blocks, articles, etc).

The built-in handling of media library items even lets us align and caption the images.

Awesome.

I know for a fact that, when using various distributions, I could also set my image to be full/three-qtr/half/one-qtr of the container.  Whatever they used ended up being in the text editor configuration filter lists I think.
