[LOW] The variable 'err' is typed as 'any' in multiple catch blocks, which reduces type safety and can lead to unclear error handling.
Suggestion: Define a proper error type or use unknown and narrow the type inside the catch block for better type safety and clarity.

[LOW] The error message strings like 'Failed to vote' are hardcoded multiple times across catch blocks.
Suggestion: Extract these repeated error message strings into named constants to avoid duplication and ease future changes.

Review Notes 🐈
This PR centralizes error handling using Axios interceptors and replaces local error/success states with react-hot-toast notifications, improving user experience and maintainability. However, it lacks sufficient documentation for key exported functions and leaves some debug logs and potential XSS risks unaddressed. Minor performance and accessibility concerns remain.
Before merging
- Add comprehensive JSDoc comments for all exported functions in api.ts, especially the error handling interceptor and utility functions.
- Sanitize error messages before displaying them in toasts to mitigate potential reflected XSS vulnerabilities.
- Remove remaining console.log debug statements and improve error logging consistency across components, particularly in DiscussionDetailPage.

🔍 Medium — The submitReplyAction function calls fetchDiscussion() after submitting a reply, which fetches the entire discussion data again, potentially causing unnecessary network load and UI blocking.
Consider updating the local state with the new reply instead of refetching the entire discussion to reduce network usage and improve responsiveness.

Changes Requested 🐈
This PR enhances error handling by centralizing Axios error interception and replacing local error states with react-hot-toast notifications, improving user feedback consistency. Reviewers noted improvements but flagged duplicated code, leftover obsolete state references, missing documentation for new helper functions, and some performance concerns. No critical bugs or security issues were found.
There are a few things I'd like to see addressed before we merge this:
Before merging
- Extract repeated error message strings into constants to improve maintainability.
- Remove all references to obsolete local error and success state variables to avoid confusion and potential bugs.
- Add JSDoc comments for new exported functions in api.ts to improve documentation and code clarity.

Review Notes 🐈
This PR enhances error handling by centralizing Axios interceptors and integrating react-hot-toast for user notifications, improving user experience and maintainability. No critical or high-severity bugs were found, but there are security concerns regarding unsanitized error messages and minimal input validation, as well as potential performance issues with refetching data and rendering inefficiencies.
Nice-to-haves
- Sanitize all error messages before displaying them to prevent potential XSS vulnerabilities.
- Implement stronger client-side validation for inputs like passwords and usernames to enhance security.
- Optimize DiscussionDetailPage by reducing full refetches after replies and using memoization to improve rendering performance.

🔍 Medium — The component renders a list of replies inside a scrollable container when there are more than 3 replies. However, the replies are mapped inline without memoization, and the parseImages function is called inside the map for each reply. This can cause unnecessary re-renders and recomputations on each render, especially if the replies list is large.
Memoize the parsed images outside the map or memoize the entire replies list rendering using React.memo or useMemo to avoid unnecessary recomputations and re-renders.

Review Notes 🐈
This PR centralizes error handling using Axios interceptors and replaces local error states with react-hot-toast notifications for improved user experience. No critical bugs or high-severity security issues were found, but medium-severity concerns about potential XSS risks from unsanitized server messages and the need for stronger server-side file validation remain. Minor performance improvements are suggested but not critical.
Nice-to-haves
- Implement sanitization or encoding of server-supplied error messages before displaying to prevent potential XSS vulnerabilities.
- Ensure strict server-side validation of uploaded files to complement client-side checks and enhance security.
- Consider memoizing inline JSX expressions and list components to optimize React rendering performance.

🔍 Medium — In the rendering of replies for each answer, the map function creates inline functions and objects inside JSX which can cause unnecessary re-renders of child components. Also, the parseImages function is called inside the map for each reply, which may be inefficient if replies are numerous.

🔍 Medium — The component renders a list of replies inside each answer with inline functions and inline object/array creation in JSX (e.g., mapping replies to JSX elements). This can cause unnecessary re-renders and performance degradation when the number of replies grows.

This PR centralizes error handling using Axios interceptors and replaces local error states with react-hot-toast notifications, improving user experience and consistency. While it enhances error messaging and Redis configuration flexibility, documentation is lacking for new functions and complex logic, and some performance and readability improvements are suggested.
There are a few things I'd like to see addressed before we merge this:
Before merging
- Add JSDoc comments for new exported functions in api.ts to improve documentation clarity.
- Include inline comments explaining the complex error handling logic in the Axios response interceptor.
- Refactor DiscussionDetailPage rendering to avoid inline functions and consider optimistic UI updates to enhance performance.

🔍 Medium — The component renders a list of replies with inline functions and inline object/array creations inside the map function, which may cause unnecessary re-renders and performance degradation when the number of replies grows.
Memoize the reply list rendering or extract the reply rendering into a separate memoized component to prevent unnecessary re-renders. Avoid inline object/array creation in JSX props inside loops.

🔍 Medium — After submitting a reply or answer, the component calls fetchDiscussion() to refresh the entire discussion data, which may be a heavy operation and cause UI blocking or slow response, especially if the discussion has many answers and replies.
Instead of refetching the entire discussion, update the local state optimistically with the new reply or answer to reduce network calls and improve responsiveness.

This PR centralizes error handling and replaces local error states with react-hot-toast notifications for improved UX. While it enhances robustness and user feedback, it lacks sufficient documentation, error logging, and has minor performance and security considerations. Several exported functions and components lack JSDoc comments, and error catch blocks miss structured logging.
There are a few things I'd like to see addressed before we merge this:
Before merging
- Add comprehensive JSDoc documentation for all new exported functions and React components.
- Implement structured error logging in catch blocks to aid debugging and maintenance.
- Remove console.log statements from production code and improve input validation with form-level checks.

This PR centralizes error handling using react-hot-toast for user-friendly notifications and improves UX consistency. However, it introduces potential security risks due to unsanitized error messages, lacks sufficient documentation, and has some performance and accessibility concerns. These issues require addressing before approval.
There are a few things I'd like to see addressed before we merge this:
Before merging
- Sanitize all user-visible error messages to prevent reflected XSS vulnerabilities.
- Add comprehensive JSDoc comments for all exported functions and React components to improve maintainability.
- Optimize rendering in DiscussionDetailPage.tsx to avoid unnecessary re-renders and reduce redundant data fetching.
