Thank you for your hard work on this project! 🌟 While your code generally meets the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:

Error Handling: There are several areas where error handling is either missing or too generic. It's important to provide specific error messages to help users understand what went wrong, especially during operations like loading users, posts, and comments, as well as during comment creation and deletion.
Typographical Errors: There are typos in function and state variable names, such as setShouldFormBeVisile and handleCommentDeliete. These should be corrected to maintain code clarity and prevent potential issues.
Email Validation: The current email validation only checks for an empty field. Implement a more robust validation to ensure the input is a valid email format.
State Management: After a successful comment submission, ensure that all form fields are reset to provide a clean slate for the user.
Code Simplification: Simplify conditions like posts && posts?.length > 0 to posts?.length > 0 for cleaner code.

Addressing these issues will enhance the functionality and maintainability of your code. Keep up the great work, and I'm confident you'll nail these improvements! 😊

src/App.tsx

+  const handleUserSelect = (user: User | null) => {
+    setSelectedUser(user);
+    setSelectedPost(null);
+    fetchPosts(user?.id || null);


The use of optional chaining (user?.id || null) is correct here to handle cases where user might be null. However, ensure that fetchPosts is designed to handle a null argument appropriately, as this could potentially lead to unexpected behavior if not handled correctly.

src/App.tsx

+                  </div>
+                )}
+
+                {posts && posts?.length > 0 && (


The check posts && posts?.length > 0 is slightly redundant because posts?.length > 0 will already ensure that posts is not null or undefined. You can simplify this condition to posts?.length > 0.

mateacademy-ai-mentor · 2025-02-11T00:23:19Z

src/api/data.ts

+export const getPosts = (id: number) => {
+  return client.get<Post[]>(`/posts?userId=${id}`);


Ensure that the id parameter passed to getPosts is validated before making the request. If id is not a valid number, it could lead to unexpected API behavior or errors.

mateacademy-ai-mentor · 2025-02-11T00:23:19Z

src/api/data.ts

+export const getComments = (postId: number) => {
+  return client.get<Comment[]>(`/comments?postId=${postId}`);


Similar to getPosts, ensure that postId is validated before making the request to avoid potential issues with invalid IDs.

mateacademy-ai-mentor · 2025-02-11T00:23:19Z

src/api/data.ts

+export const deleteComment = (commentId: number) => {
+  return client.delete(`/comments/${commentId}`);


Consider adding error handling for the deleteComment function to manage cases where the comment might not exist or the deletion fails.

mateacademy-ai-mentor · 2025-02-11T00:23:21Z

src/components/UserSelector.tsx

+          {usersFromServer.map(user => (
+            <UserItem
+              key={user.id}
+              user={user}
+              onSelect={handleUserSelect}
+              isActive={user.id === activeUser?.id}
+            />
+          ))}


Consider adding a loading state or a message to indicate when users are being fetched from the server, especially if the fetching process takes noticeable time.

mateacademy-ai-mentor · 2025-02-11T00:23:21Z

src/utils/fetchClient.ts

-    .then(response => response.json());
+    .then(response => {
+      if (!response.ok) {
+        throw new Error();


The error thrown here is generic. Consider providing a more descriptive error message or including the response status and status text to aid in debugging.

mateacademy-ai-mentor · 2025-02-11T00:23:21Z

src/utils/hooks.ts

+    postService
+      .getUsers()
+      .then(data => setUsers(data))
+      .catch(() => onError('Something went wrong!'));


Consider providing more specific error messages in the catch block to help users understand what went wrong during the user loading process.

mateacademy-ai-mentor · 2025-02-11T00:23:21Z

src/utils/hooks.ts

+      postService
+        .getPosts(userId)
+        .then(setPosts)
+        .catch(() => onError('Something went wrong!'))


Similar to the user loading, consider providing more specific error messages for post loading failures to aid in debugging and user feedback.

mateacademy-ai-mentor · 2025-02-11T00:23:21Z

src/utils/hooks.ts

+        const createdComment = await postService.postComment(newComment);
+
+        setComment(createdComment);
+      } catch {


Providing more specific error messages for comment creation failures can help users understand the issue better and improve the debugging process.

Great job on your submission! 🎉 While there are some areas for improvement, the overall structure and functionality of your code are solid. Here are a few key points to focus on:

Error Handling: Many components and hooks have generic error messages like "Something went wrong!" Consider providing more specific error messages to help users understand what went wrong and improve debugging.
Email Validation: Enhance the email validation in the NewCommentForm component to ensure a valid email format is used.
State Management: After a successful comment submission, ensure all form fields are reset to provide a clean slate for the user.
Code Simplification: Simplify conditions like posts && posts?.length > 0 to posts?.length > 0 for cleaner code.
API Error Handling: Add error handling for API functions to manage potential errors during HTTP requests effectively.

These improvements will enhance the user experience and code maintainability. Keep up the great work, and use this feedback to refine your skills further! 🚀

src/App.tsx

+                  </div>
+                )}
+
+                {posts && posts?.length > 0 && (


The condition posts && posts?.length > 0 can be simplified to posts?.length > 0. This makes the code cleaner and easier to read.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/api/data.ts

+export const getUsers = () => {
+  return client.get<User[]>('/users');
+};
+
+export const getPosts = (id: number) => {
+  return client.get<Post[]>(`/posts?userId=${id}`);
+};
+
+export const getComments = (postId: number) => {
+  return client.get<Comment[]>(`/comments?postId=${postId}`);
+};
+
+export const deleteComment = (commentId: number) => {
+  return client.delete(`/comments/${commentId}`);
+};
+
+export const postComment = (comment: Omit<Comment, 'id'>) => {
+  return client.post<Comment>('/comments', comment);
+};


Consider adding error handling for these API functions. This can be done by using try-catch blocks or handling promise rejections to ensure that any errors during the HTTP requests are managed appropriately.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/components/CommentItem.tsx

+    try {
+      await handleDelete(comment.id);
+      onDelete(comment.id);
+    } catch (error) {}


The catch block is currently empty. Consider handling the error by providing feedback to the user or logging the error. This will help in debugging and improve user experience by informing them of any issues during the deletion process.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/components/NewCommentForm.tsx

+  const handleSubmit = (event: React.FormEvent) => {
+    event.preventDefault();
+    setHasTitleError(!titleVal);
+    setHasEmailError(!emailVal);


The current email validation only checks if the email field is empty. Consider implementing a more robust validation to ensure the input is a valid email format. This will help prevent invalid email addresses from being submitted.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/components/NewCommentForm.tsx

+  useEffect(() => {
+    if (comment) {
+      onSubmit(comment);
+      setCommentVal('');


After a successful comment submission, ensure that all form fields are reset to provide a clean slate for the user. Currently, only the comment field is being reset.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/components/PostDetails.tsx

+      .then(data => {
+        setComments(data);
+      })
+      .catch(() => setErrorMessage('Something went wrong!'))


The error message 'Something went wrong!' is quite generic. Consider providing a more specific error message to help users understand what went wrong during the comment loading process.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/components/UserSelector.tsx

+  activeUser,
+}) => {
+  const [isDropdownOpen, setIsDropdownOpen] = useState(false);
+  const usersFromServer = useLoadUsers(onError);


Ensure that the error handling for loading users is robust. Consider displaying an error message to the user if the useLoadUsers hook encounters an error, to provide clear feedback and improve the user experience.

mateacademy-ai-mentor · 2025-02-11T10:15:18Z

src/utils/fetchClient.ts

-    .then(response => response.json());
+    .then(response => {
+      if (!response.ok) {
+        throw new Error();


The error handling here is quite generic. Consider throwing an error with more detailed information, such as the response status or message, to aid in debugging and provide clearer feedback.

mateacademy-ai-mentor · 2025-02-11T10:15:19Z

src/utils/hooks.ts

+    postService
+      .getUsers()
+      .then(data => setUsers(data))
+      .catch(() => onError('Something went wrong!'));


The error message 'Something went wrong!' is quite generic. Consider providing a more specific error message to help users understand what went wrong during the user loading process.

mateacademy-ai-mentor · 2025-02-11T10:15:19Z

+      postService
+        .getPosts(userId)
+        .then(setPosts)
+        .catch(() => onError('Something went wrong!'))


The error message 'Something went wrong!' is quite generic. Consider providing a more specific error message to help users understand what went wrong during the post loading process.
