How to implement the "client hook system" in yii2 in the least cycling way?

Question

Yii

Don't be alarmed, I just came up with the term myself, but here's what you need:
A user from the admin panel writes a certain shortcode in the page text - and on the site on this page, a certain widget or view is rendered in place of this shortcode.
In my opinion, the task is the most trivial, but I fell into a stupor on how to do it correctly. Isn't it possible to skip the text of pages through str_replace and replace shortcodes with the result of rendering the desired view? Well, if not out of the box, then what kind of extensions for the convenient implementation of such functionality should definitely be?
I would be grateful not even for a complete answer, but for a kick in the right direction.

Answer 1

implement an interpreter on the back to determine shortcodes and replace them with the data you need

Answer 2

Don't you want to completely transfer this task to the frontend?
That is, the user's shortcode is rendered on the page as a shortcode, processed by JS, which loads the desired view.
