Scopri come gestire l'autenticazione in un'app React utilizzando Express e Passport con JWT. Questo articolo esplora il processo di memorizzazione di un token JWT nel local storage del browser e risolve il problema del recupero del token. Ottimizza la tua app con queste strategie efficaci!

I'm building an app using React and Express and I'm trying to store a JWT token in the browser local storage. I'm using Passport (with JWT strategy) and React Router to handle authentication. When a user logs in, I get back an access token from the server and I'm trying to store it in the browser local storage. I'm using React's useEffect hook to do this. Inside the useEffect hook, I have the following code: // Set token in local storage const setToken = (token) => { localStorage.setItem('token', token); }; // Get token from local storage const getToken = () => { return localStorage.getItem('token'); }; The setToken function is called after the user has logged in, and the getToken function is called when the user refreshes the page. However, the getToken function always returns null, even though I know the token is stored in the local storage. Any ideas on what might be causing this?
