Code Review
This pull request correctly resolves a critical bug that was causing the Vite development server to crash by properly handling an asynchronous API call within the LoginPage component. The fix is well-implemented. My review includes suggestions to further enhance the component by adding a loading state to provide user feedback during the login process and prevent multiple submissions. I've also recommended improvements to form accessibility by correctly associating labels with their input fields. These changes will improve the user experience and make the component more robust and accessible.

To improve user experience and prevent multiple form submissions, it's a good practice to add a loading state to manage the asynchronous login process. This state can be used to disable the submit button and provide visual feedback to the user while the API call is in progress.

| const [error, setError] = useState('') | |

|
|
||
| if (response.success) { | ||
| navigate('/dashboard') | ||
| } else { | ||
| setError(response.error || 'Login failed') | ||
| } | ||
| } catch (err) { | ||
| setError('An error occurred during login') | ||
| console.error(err) | ||
| } | ||
| } |

The handleLogin function should be updated to manage the loading state. Set it to true before the API call and false in a finally block to ensure it's always reset, even if an error occurs. Also, you can prevent new login attempts while one is already in progress by checking the loading state.
const handleLogin = async () => {
if (loading) return
setLoading(true)
try {
setError('')
const response = await apiService.login(email, password)
if (response.success) {
navigate('/dashboard')
} else {
setError(response.error || 'Login failed')
}
} catch (err) {
setError('An error occurred during login')
console.error(err)
} finally {
setLoading(false)
}
}

For better accessibility, you should associate labels with their corresponding input fields using htmlFor on the label and id on the input. This helps screen readers and improves the user experience, as clicking the label will focus the input.
<label htmlFor="email" className="block text-white mb-2">Email</label>
<input
id="email"
type="email"
value={email}
onChange={e => setEmail(e.target.value)}

To provide feedback to the user and prevent multiple submissions, the login button should be disabled and its text updated while the login request is in progress. You can also add styles for the disabled state using Tailwind CSS.
<button
type="submit"
className="w-full bg-blue-600 text-white py-2 rounded hover:bg-blue-700 transition-colors disabled:bg-blue-400 disabled:cursor-not-allowed"
disabled={loading}
>
{loading ? 'Logging in...' : 'Login'}
</button>
