LocalStorage and useEffect

In a typical CRUD scenario, one would be using the above mentioned like this:
• useEffect => On load: check if localStorage data exists, then parse it and save in state.
• useEffect => Listens for changes in state data, then saves it to localStorage.

How can I prevent the second

useEffect

useEffect

from running after the first on initial load?

Let's say I have already added some data in localStorage. When my app loads, it fetches said data and calls

setState

setState

to save it in my local state. Since this data is in the dependency array of the second

useEffect

useEffect

, it triggers it, saving nothing.

Thanks!
