Why Web UI Development Is So Hard?

Web UI development might appear straightforward at first glance, but delve deeper and you’ll discover a multitude of complexities that challenge even seasoned developers.

Navigating Language Mismatches

Unless you’re building a straightforward, document-like webpage, the built-in languages offered by web browsers are generally insufficient. Native web languages often don't cater to the intricate demands of modern web UIs. Simulating complex UI components remains a challenge, as the web is fundamentally designed around documents rather than true UI components.

While visual UI designers like C++ Builder, Delphi, or Figma provide intuitive drag-and-drop interfaces, web development demands manual labor, customization, and finesse for each UI component.

Understanding State Management

State management in frontend development is intricate. Whether it's remote data retrieval or local component management, developers must cater to various concerns such as API access, data-fetching protocols, and more.

The challenge escalates when third-party components introduce errors or unpredictable behaviors. For instance:

const MenuItem = ({
  item,
  onItemClick,
}: {
  item: MenuItemType;
  onItemClick: (item: MenuItemType) => void;
}) => {
  // @ts-ignore
  const information  = item.name + item.something.doesnt.exist;
  return (
    <li key={item.name}>
      <h3>{item.name}</h3>
      <p>{item.description}</p>
      <button onClick={() => onItemClick(item)}>Add to Cart</button>
    </li>
  );
};

Accessing Remote State Over the Network

React presents its own set of network programming challenges. Beyond the direct task of API calls, considerations for error handling, caching, and retry mechanisms demand attention.

Consider the following naive approach using the

hook:

const [users, setUsers] = useState<User[]>([])
useEffect(() => {
  const fetchUsers = () => {
    fetch('https://jsonplaceholder.typicode.com/users')
      .then((response) => response.json())
      .then((data) => setUsers(data));
  }
  fetchUsers();
}, []);

But real-world scenarios require more nuanced approaches:

const [loading, setLoading] = useState<boolean>(false);
const [error, setError] = useState<string>('');
useEffect(() => {
  const fetchUsers = () => {
    setLoading(true);
    fetch('https://jsonplaceholder.typicode.com/users2')
      .then((response) => {
        if (response.status >= 200 && response.status <= 299) {
          return response.json();
        } else {
          setLoading(false);
          throw Error(response.statusText);
        }
      })
      .then((data) => {
        setLoading(false);
        setUsers(data);
      })
      .catch((e) => {
        setLoading(false);
        setError(e);
      });
  }
  fetchUsers();
}, []);
if(error) {
  return <ErrorMessage />
}

Other Considerations

Web UI development teems with intricacies:

• Cross-browser Compatibility: Variations in browser rendering engines necessitate thorough compatibility testing.

• Performance Optimization: Enhancing website efficiency demands an understanding of browser rendering, asset optimization, lazy loading, and more.

• Accessibility: Crafting universally accessible websites necessitates special considerations and testing.

• Security Concerns: Front-end applications must safeguard against threats like XSS, CSRF, and potential client-side data leaks.

Each of these could be explored in depth in its own article, but for brevity's sake, they're succinctly listed here.

Summary

Web UI development is rife with challenges that aren't immediately evident. The language constraints, data management complexities, and overlooked "unhappy paths" compound the intricacy of this domain. Delving into architectural concerns related to security, performance, and accessibility only adds to the complexity.

Recognizing these challenges is the first step. By understanding them, developers can navigate the maze of web UI development more effectively, resulting in interfaces that are not only visually appealing but also robust, secure, and user-centric.
