52-63: Optimize setValue to prevent unnecessary updates.The current implementation of
setValuecould trigger unnecessary re-renders. Consider these improvements:
- Memoize the value transformation:
const setValue = useCallback( (value: string) => { + const transformValue = (input: string) => { + input = input.replaceAll(/[^0-9+]/g, ""); + if (input.length > 12 && input.startsWith("+910")) { + input = "+91" + input.slice(4); + } + return input; + }; - value = value.replaceAll(/[^0-9+]/g, ""); - if (value.length > 12 && value.startsWith("+910")) { - value = "+91" + value.slice(4); - } + const transformedValue = transformValue(value); + if (transformedValue === field.value) return; - const error = validate(value, "change"); - field.handleChange(value); + const error = validate(transformedValue, "change"); + field.handleChange(transformedValue); setError(error); }, [field, validate, error], );

38-51: Consider consolidating error handling and improving validation strategy.The current implementation maintains two sources of error state (
field.errorand localerrorstate) which could lead to inconsistent behavior. Consider these improvements:
- Consolidate error handling:
interface ValidationState { error?: FieldError; isDirty: boolean; } const [validationState, setValidationState] = useState<ValidationState>({ error: undefined, isDirty: false }); const validate = useCallback((value: string | undefined, event: "blur" | "change") => { if (!value || props.disableValidation) { return; } const newError = validator(value); setValidationState(prev => ({ error: newError, isDirty: event === "blur" || prev.isDirty })); if (props.onError) { props.onError(newError); } }, [props.disableValidation, validator, props.onError]);
- Improve validation timing:
- Validate on blur for better UX
- Debounce validation on change to prevent rapid re-renders
- Show errors only after the field is dirty

133-157: Enhance accessibility and keyboard navigation.The component could benefit from improved accessibility features:
- Add ARIA labels and roles:
<PopoverButton className="absolute h-full"> <div className="hover:border-1 absolute inset-y-0 left-0 flex cursor-pointer items-center justify-around border-gray-200 hover:border hover:bg-gray-50" + role="combobox" + aria-label="Select country code" + aria-expanded={open} >
- Improve keyboard navigation:
<input type="tel" id={field.id} name={field.name} autoComplete={props.autoComplete ?? "tel"} + aria-invalid={!!field.error} + aria-describedby={field.error ? `${field.id}-error` : undefined} className={classNames( "cui-input-base h-full pl-14 tracking-widest sm:leading-6", field.error && "border-danger-500", field.className, )}
- Add screen reader announcements for validation errors:
{field.error && ( + <div id={`${field.id}-error`} role="alert" className="text-danger-500"> {field.error.message} + </div> )}

107-108: Verify the infinite render fix across the codebase.
Let's ensure there are no other components that might trigger infinite renders with the PhoneNumberFormField.
✅ Verification successful
Based on the verification results, I can now provide a final response:
The infinite render fix is properly implemented and isolated.
The verification shows that:
- The
useEffectin PhoneNumberFormField only updates state when the field value changes, with proper conditions to prevent loops - The component is used consistently across the codebase with standard props
- No circular dependencies or cascading state updates are present in the implementation
The two main useEffect hooks in PhoneNumberFormField have proper dependencies:
- Error propagation effect depends only on
error - Country code effect depends only on
field.valuewith appropriate conditionals
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Find all usages of PhoneNumberFormField and potential infinite render scenarios
# Find all files that import or use PhoneNumberFormField
echo "Searching for PhoneNumberFormField usage..."
rg -l "PhoneNumberFormField"
# Find potential infinite render scenarios in React components
echo "Checking for potential infinite render patterns..."
ast-grep --pattern 'useEffect($$$) {
$$$
setValue($$$);

}'
# Find other phone number related components
echo "Checking for related phone number components..."
rg -l "PhoneNumber|phone.*number|phone.*field" --type ts --type tsx
Length of output: 1114
