How gross violation is it considered to write logic in a reducer and not in an action?

Question

React

How gross is it to write logic in a reducer and not in an action?
how to stick to this, it doesn't always work out to keep reducers clean
example prntscr.com/glnbs3 prntscr.com/glnazt when I write this kind of code am I showing my inexperience? Do I need to fight it and take it to the action? does it violate the purity of the function? could this be a problem? why is that bad?

Answer 1

By convention, reducers should remain pure functions, and for your solution, you can use asynchronous actions to keep the logic in the actions
