Is it possible to add a default action to vue?

Question

Vue.js

For example, in all Vue instances, in the updated method, I need to add some code, such as raising an event. (for example, to listen to this event in a third-party plugin) how can this be done without copying the code? maybe you can do it somehow in main.js?
(I'm a beginner and the front is not my main activity but I need to master it a bit)
