Technical Implementation Highlights
Frontend Architecture
// Example of component structure
const Tenants = () => {
const [tenants, setTenants] = useState([]);
const [loading, setLoading] = useState(false);
const [openModal, setOpenModal] = useState(false);
const fetchTenants = useCallback(async () => {
setLoading(true);
try {
const response = await axios.get('/api/tenants');
setTenants(response.data);
} catch (error) {
toast.error('Failed to fetch tenants');
} finally {
setLoading(false);
}
}, []);
// Component logic...
};
