[No-QA] chore: [Performance] Optimize useFilterFormValues (~16ms per render) by TaduJR · Pull Request #83746 · Expensify/App

TaduJR · 2026-02-27T19:11:37Z

Explanation of Change

useFilterFormValues ran in both SearchPage and useSearchFiltersBar, creating duplicate Onyx subscriptions and running buildFilterFormValuesFromQuery twice per render. Additionally, every useOnyx(ONYXKEYS.COLLECTION.POLICY) call across the search filter hooks subscribed to the entire policy object — triggering deepEqual comparisons on massive objects (employeeList, connections, customUnits, rules, etc.) whenever any policy field changed.

Removes the duplicate useFilterFormValues + useSearchFilterSync from SearchPage — keeps them only in useSearchFiltersBar, the sole consumer.
Adds Onyx selectors to all 7 collection subscriptions across 4 hooks, each extracting only the fields actually consumed downstream:
- useFilterFormValues: policiesSelector (taxRates only), reportsSelector (reportID only), policyCategoriesSelector (name only), policyTagsSelector (tag names only)
- useSearchFiltersBar: typeOptionsPoliciesSelector (9 fields for canSendInvoice check)
- useAdvancedSearchFilters: advancedSearchPoliciesSelector (17 fields for filter visibility)
- useExportedToFilterOptions: exportedToPoliciesSelector (id, name, connections, exportLayouts)
Optimizes buildFilterFormValuesFromQuery — hoists 4 constant validation Sets to module level, pre-computes 3 dynamic Sets before the filter loop, and replaces getTagNamesFromTagsLists with direct inline
iteration into Sets for TAG/CATEGORY paths.
Optimizes getAllTaxRatesNamesAndKeys in PolicyUtils — replaces O(n) .includes() deduplication with O(1) Set-based lookup.

@TaduJR can you provide measurements on the performance improvement please?

luacmartins · 2026-02-27T19:15:10Z

We also have several lint issues on SearchPage. A lot of that logic was removed already

Hmm I think they are occurring after merging with main. Let me check

Reviewer Checklist

I have verified the author checklist is complete (all boxes are checked off).
I verified the correct issue is linked in the ### Fixed Issues section above
I verified testing steps are clear and they cover the changes made in this PR
- I verified the steps for local testing are in the Tests section
- I verified the steps for Staging and/or Production testing are in the QA steps section
- I verified the steps cover any possible failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
- I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
I checked that screenshots or videos are included for tests on all platforms
I included screenshots or videos for tests on all platforms
I verified tests pass on all platforms & I tested again on:
- Android: HybridApp
- Android: mWeb Chrome
- iOS: HybridApp
- iOS: mWeb Safari
- MacOS: Chrome / Safari
If there are any errors in the console that are unrelated to this PR, I either fixed them (preferred) or linked to where I reported them in Slack
I verified proper code patterns were followed (see Reviewing the code)
- I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick).
- I verified that the left part of a conditional rendering a React component is a boolean and NOT a string, e.g. myBool && <MyComponent />.
- I verified that comments were added to code that is not self explanatory
- I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
- I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
- I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
- I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
- I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
- I verified the JSDocs style guidelines (in STYLE.md) were followed
If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
I verified that this PR follows the guidelines as stated in the Review Guidelines
I verified other components that can be impacted by these changes have been tested, and I retested again (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar have been tested & I retested again)
I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
If a new component is created I verified that:
- A similar component doesn't exist in the codebase
- All props are defined accurately and each prop has a /** comment above it */
- The file is named correctly
- The component has a clear name that is non-ambiguous and the purpose of the component can be inferred from the name alone
- The only data being stored in the state is data necessary for rendering and nothing else
- For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)
- Any internal methods bound to this are necessary to be bound (i.e. avoid this.submit = this.submit.bind(this); if this.submit is never passed to a component event handler like onClick)
- All JSX used for rendering exists in the render method
- The component has the minimum amount of code necessary for its purpose, and it is broken down into smaller components in order to separate concerns and functions
If any new file was added I verified that:
- The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
If a new CSS style is added I verified that:
- A similar style doesn't already exist
- The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG)
If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
- I verified that all the inputs inside a form are aligned with each other.
- I added Design label and/or tagged @Expensify/design so the design team can review the changes.
If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.
I have checked off every checkbox in the PR reviewer checklist, including those that don't apply to this PR.

src/hooks/useFilterFormValues.tsx

Pujan92 · 2026-03-06T18:15:10Z

Change 1: Deduplicate the hook — remove it from SearchPage, keep it only in SearchFiltersBar.

Remove the useFilterFormValues call and its useEffect sync from SearchPage.tsx. Move the updateAdvancedFilters(formValues, true) sync into SearchFiltersBar.tsx where the hook already exists. This eliminates 6 duplicate Onyx subscriptions and halves buildFilterFormValuesFromQuery execution.

@TaduJR Aren't we implementing the suggested change in your proposal of using useSearchFilterSync(filterFormValues); to avoid it in SearchPage?
