Handling Browser Storage with React Hooks

Let’s start with an issue that is listed on many platforms but not with the exact solution.

• localStorage won’t update values 🤔
• local storage in react is not storing the updated value 😐
• localStorage not working properly in ReactJS 😑
• localStorage value doesn’t get updated automatically 😫

This is a very common issue when you need to store data in the browser by using any methods sessionStorage or localStorage with React Hooks.

let's get rid out of it. 😎

Scenario

I have a language that I change on the selection of dropdown and store on the browser.

const [language, setLanguage] = useState(null);
const changeLang = () => {
    // update language
     setLanguage("en-IN");
    // store language in browser as well
    localStorage.setItem('language', language);
}

Does the above snippet look fine and store data???🙄 Noooo!!!! It can’t store on the first hit, Because of the async behavior of setLanguage in useState()hooks

Solution ☺️

useEffect(() => {
   localStorage.setItem('language', language);
}, [language])

This is nothing but a dependent state which gets fire when the language gets changed.

That's It!!!

Enjoy browser storage peacefully 😍
