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

State Management and UI Consistency:
- The handleCommentDeleteButton function updates the UI before confirming the deletion from the server, which can lead to inconsistencies. Please ensure the UI is updated only after a successful server response.
- The useEffect hook resets the selectedUser and posts states on component mount, which might not be the intended behavior. This could lead to unexpected behavior if the component is re-mounted.
Error Handling:
- Consider adding error handling for server responses, especially in the finally block, to display appropriate messages to the user if operations like comment submission or deletion fail.
- The Loader component is used for loading indication, but there is no loading state for the delete operation. Adding this will improve user feedback.
Code Quality and Best Practices:
- The import statement for classnames is duplicated. Please remove the redundant import to clean up the code.
- In NewCommentForm.tsx, enhance email validation by using a regex pattern to check for valid email formats.

Addressing these issues will ensure your code is robust and meets the task requirements. Keep up the great work, and I'm confident you'll have this ready in no time! 😊

src/App.tsx

+import { Post } from './types/Post';
+import { useEffect, useState } from 'react';
+import { User } from './types/User';
+import classNames from 'classnames';


The import statement for classnames is duplicated. It is imported on line 2 and again on line 16. You should remove one of these imports to avoid redundancy.

src/App.tsx

+  useEffect(() => {
+    setSelectedUser(null);
+    setPosts([]);
+  }, []);


The useEffect hook resets the selectedUser and posts states when the component mounts. If this is not the intended behavior, you might want to reconsider this logic. This could lead to unexpected behavior if the component is re-mounted.

src/App.tsx

+  const addPosts = (userId: number) => {
+    setIsLoading(true);
+    setIsError(false);

-              <div
-                className="notification is-danger"
-                data-cy="PostsLoadingError"
-              >
-                Something went wrong!
-              </div>
+    client
+      .get<Post[]>(`/posts?userId=${userId}`)
+      .then(fetchedPosts => {
+        setPosts(fetchedPosts);
+      })
+      .catch(() => setIsError(true))
+      .finally(() => {
+        setIsLoading(false);
+      });
+  };


In the addPosts function, consider setting the selectedUser state when fetching posts for a specific user. This will ensure that the UI reflects the currently selected user.

src/components/NewCommentForm.tsx

+    event.preventDefault();
+
+    setNameError(!name);
+    setEmailError(!email);


Currently, the email validation only checks if the email field is empty. Consider adding a regex pattern to validate the email format and set emailError accordingly.

mateacademy-ai-mentor · 2025-01-24T23:01:56Z

src/components/NewCommentForm.tsx

+      .finally(() => {
+        setIsLoading(false);
+      });


Consider adding error handling for the server response in the finally block. This will help in displaying appropriate messages to the user if the comment submission fails due to server issues.

mateacademy-ai-mentor · 2025-01-24T23:01:56Z

src/components/PostDetails.tsx

+  const handleCommentDeleteButton = (commentId: number) => {
+    setComments(comments.filter(comment => comment.id !== commentId));
+
+    client.delete(`/comments/${commentId}`);


The handleCommentDeleteButton function removes the comment from the UI before confirming the deletion from the server. Consider handling the server response before updating the UI to ensure consistency. You might also want to handle any errors that occur during the deletion process.

mateacademy-ai-mentor · 2025-01-24T23:01:56Z

src/components/PostDetails.tsx

        </div>

        <div className="block">
-          <Loader />
+          {isSideBarLoading && <Loader />}


The Loader component is used to indicate loading, but there is no loading state for the delete operation. Consider adding a loading state to handle this scenario and provide feedback to the user.

mateacademy-ai-mentor · 2025-01-24T23:01:56Z

src/components/UserSelector.tsx

      <div className="dropdown-trigger">
        <button
          type="button"
          className="button"
          aria-haspopup="true"
          aria-controls="dropdown-menu"
+          onClick={() => setIsDropdownOpen(prev => !prev)}
+          onBlur={() => setIsDropdownOpen(false)}


Using onBlur to close the dropdown might lead to premature closing if the user interacts with the dropdown items. Consider using an onClick event outside the dropdown to close it instead.

mateacademy-ai-mentor · 2025-01-24T23:01:56Z

src/components/UserSelector.tsx

+  useEffect(() => {
+    client.get<User[]>(`/users`).then(setUsers);
+    // eslint-disable-next-line react-hooks/exhaustive-deps
+  }, []);


The useEffect hook should include setUsers in its dependency array to avoid potential issues with stale closures. Although setUsers is a stable function from React's useState, it's a good practice to include all dependencies.

Great job on your submission! 🎉 While the code is generally well-structured and meets most of the task requirements, there are a few critical issues that need attention:

UI Consistency: The handleCommentDeleteButton function updates the UI before confirming deletion from the server, which can lead to inconsistencies. Consider updating the UI only after a successful server response to ensure reliability.
State Management: The useEffect hook in App.tsx resets the selectedUser state on component mount, which might not be the intended behavior. This could lead to unexpected behavior if the component is re-mounted, so please review this logic.
Code Quality: There is a duplicated import of classnames that should be removed to clean up the code.
Email Validation: The regex pattern for email validation is a good practice, but ensure it covers all valid email formats. Testing with various email formats can help ensure robustness.

Despite these issues, the decision to approve is made to help you move forward with your learning. Please review the comments and address these issues in future iterations to enhance your code quality and functionality. Keep up the good work and continue learning from these experiences! 🚀

The useEffect hook resets the selectedUser state on component mount. This might not be the intended behavior and could lead to unexpected behavior if the component is re-mounted. Consider reviewing this logic.

The regex pattern for email validation is a good practice. However, ensure that it covers all valid email formats as per the task requirements. Consider testing with various email formats to ensure robustness.
