Reactjs – useNavigate doesn't work after an API call

Here’s my code:


export default function SignUp() {
    const [user, setUser] = useState({ id: null, firstName: '', lastName: '', email: '', password: '' });
    const [isLoading, setIsLoading] = useState(false);
    const [error, setError] = useState('')
    const navigate = useNavigate();

    const CLIENT_URL = 'http://localhost:8080';

    const isNotValid = user.firstName === '' || user.lastName === '' || user.email === '' || user.password === '';

    // Handle change in form fields
    const handleChange = e => {
        const { name, value } = e.target;
        setUser({ ...user, [name]: value })
    }

    // Handle submit event on form
    const handleSubmit = async (event) => {
        event.preventDefault();
        setIsLoading(true);
        setError('');

        try {
            // Validate form fields
            if (isNotValid) {
                throw new Error('All fields are required');
            }

            const response = await fetch(`${CLIENT_URL}/sign-up`, {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({
                    firstName: user.firstName,
                    lastName: user.lastName,
                    email: user.email,
                    password: user.password
                }),
            });

            if (!response.ok) {
                throw new Error('Failed to sign up user');
            }

            // Process response data if needed
            const responseData = await response.json();

            // Navigate to overview page on successful sign up
            navigate('/overview');
        }
        catch (error) {
            setError(error.message);
        } finally {
            setIsLoading(false);
        }
    }

The API call works as intended, but the page is not being redirected.

I did this before in a previous project and it works, but now it doesn’t. Really confused and would like some help.

Is it something with the code? Or is it due to another error such as different versions of react-router-dom and such?

    Based on your description, it seems that the issue could be related to how you’re using useNavigate from react-router-dom. If your previous project was using an older version of react-router-dom (like v5), and your current project is using a more recent version (like v6), there are indeed differences in how navigation is handled.

    In React Router v6, the useNavigate hook returns a function that you should call directly to navigate. Your use of navigate('/overview') looks correct for React Router v6, so the syntax itself should work if you’re on v6.

    Here are a few things you could check or try to troubleshoot the issue:

    1. Check Your react-router-dom Version:
      Make sure your project is actually using React Router v6. You can check your package.json file or run npm list react-router-dom in your terminal.

    2. Check the Imports:
      Make sure that you’re importing useNavigate correctly from react-router-dom. The import should look like this:

      import { useNavigate } from 'react-router-dom';

    3. Check for Errors:
      Make sure that there are no errors in your console that might be preventing the navigation from executing. Since you’re catching and displaying errors with setError(error.message), check to see if any errors are being displayed on your UI.

    4. Placement and Usage of navigate:
      Ensure that the navigate('/overview') function call is being reached. You might want to add a console.log() statement right before the navigate call to see if it’s being executed. If there’s an exception being thrown before it reaches navigate, or if the if (!response.ok) check fails, it won’t navigate.

    5. Async/Await Handling:
      Your handleSubmit function is properly structured to handle asynchronous operations with await. However, make sure that no part of your asynchronous operation is failing silently. You could enhance the error handling to log more details or to ensure that the entire try block is executing as expected.

    6. Routing Configuration:
      Ensure that your routing configuration (possibly in an App.js or Router.js file) is set up correctly and that the /overview route exists and is configured correctly to render the appropriate component.

    7. Version-Specific Documentation:
      If you recently upgraded to v6, it might be helpful to review the React Router v6 migration guide and the React Router v6 documentation to ensure all usages conform to the new standards.

    If after checking these points the issue still persists, it might be useful to look at other parts of your application configuration or even at the network activity in your browser’s developer tools to ensure the API call is behaving as expected and that no network issues are interfering with the operation of your application.

    import { useNavigate } from ‘react-router-dom’;

    const MyComponent = () => {
    const navigate = useNavigate();

    const fetchDataAndNavigate = async () => {
    try {
        const data = await fetchMyApi();
        // Process data
        navigate('/next-page');
    } catch (error) {
        console.error('Error fetching data:', error);
    }
};

useEffect(() => {
    fetchDataAndNavigate();
}, []); // Empty dependency array to run only once on mount

return (
    <div>
        {/* Component content */}
    </div>
);

    };
