How hard is it to remake a React app for Redux?

Question

JavaScript

There is a ready-made application in react with 3 rather large main elements. Each has about 200-300 state and approximately 50-60 () => logic functions (they still have their own states, but they are of little interest
) passing states back and forth.
Questions:
-How to redo the functionality as quickly as possible in order to save all the states in one place (the variable name is unique for everyone in the application)?
-If all the logic is already written inside the elements, is it possible to do without seducers and just store the states?
-this.setState, this.state. and other pointing to states need to be changed or do they remain the same?

Answer 1

It's not all that difficult. Inside functions, transfer to redux, store state in redux, and everything else is the same.
