Hello @Anchel123, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request addresses issue #683 by optimizing the table search filtering within the TableComponent. The primary changes involve debouncing the state updates related to the search input and memoizing the filter function to prevent unnecessary re-renders and improve performance. The filtering logic is now performed with a 500ms delay after the user stops typing, and the filter function is only re-created when the search term changes.
Highlights
- Performance Optimization: Implements debounced state for the search input to reduce the frequency of filtering operations.
- Memoization: Uses
useCallbackto memoize thehandleSearchFilterfunction, preventing unnecessary re-renders of the table rows. - Filtered Rows State: Introduces a
filteredRowsstate to hold the filtered rows, updating it based on the debounced search input.
Changelog
- app/components/TableComponent.tsx
- Imported
useCallbackanduseEffectfrom 'react'. (line 13) - Added
filteredRowsstate to store the filtered rows. (line 49) - Implemented
handleSearchFilterusinguseCallbackto memoize the filter function based on thesearchterm. (line 51) - Introduced a
useEffecthook to debounce the filtering logic, updatingfilteredRows500ms after thesearchterm changes. (line 70) - Moved the
handleSetEditablefunction below theuseEffecthook. (line 82) - Updated the table body to render
filteredRowsinstead of directly filtering therowsarray. (line 148)

Trivia time!
What is the primary use case for the useCallback hook in React?
Click here for the answer
The primary use case for the useCallback hook in React is to memoize a function instance so that it can be passed as a prop to child components without causing unnecessary re-renders.

Code Review
The pull request addresses issue #683 by optimizing the table search filtering using debounced state and a memoized filter function. This approach aims to improve performance by reducing the number of filter operations performed during search. The changes include the introduction of useCallback for the handleSearchFilter function, a useEffect hook for debouncing the filter operation, and the use of a filteredRows state variable to store the filtered rows. Overall, the changes seem well-structured and should contribute to a smoother user experience.
Merge Readiness
The changes implemented in this pull request appear to be well-structured and address the performance issue effectively. The use of useCallback and useEffect with debouncing is a good approach to optimize the search filtering. The code is generally clear and easy to follow. Given the nature of the changes and the potential performance improvements, this pull request seems ready to be merged. However, as I am unable to directly approve the pull request, I recommend that other reviewers also examine the code and provide their approval before merging. Ensure that all tests pass and that the changes do not introduce any regressions.
