Retrieve and update content before rendering on frontend

[michal855]

Hello 👋 So I’ve got this module written by myself, it does numerous things on the backend. Now I need to work with the frontend, but I don’t know if what I’m trying to do is even possible. 🤷‍♂️

Would like to retrieve html content before it’s being rendered, pass it through a function, modify the content and return a new output to render. And I mean content from like other modules (it should happen while user visits a page). Need this to write a specific filter and it has to happen on the server side… otherwise I probably would be using javascript in the browser…

so… is it possible? Hope you guys get my point.

thank you.
