…ors correctly and tested functionality. Users can now enter any country code without issues.

Proposed Changes

  • Fixes Fix Infinite render on country code change #9337
  • Added a fallback for cases where getCountryCode(field.value) returns undefined or does not map to a valid entry in phoneCodes
  • Modified setCountry calls to avoid redundant updates by comparing the new value with the current state.
  • Added logic to handle cases where field.value is empty or removed.
  • Cleaned up the dependency array to include only field.value, ensuring useEffect runs only when necessary.
  • Grouped specific conditions (e.g., field.value === "+", field.value.startsWith("1800")) and ensured default fallbacks are handled appropriately.

Walkthrough

The changes in PhoneNumberFormField.tsx focus on enhancing the logic for country selection based on phone number input. The useEffect hook has been updated to include checks for specific prefixes, improving the handling of country codes. The implementation now ensures that the state is updated only when a valid country is identified, and resets to "Unknown" if not. The validation logic has also been refined to incorporate a new prop, ensuring better error handling and user experience.

99-109: LGTM! Consider extracting special country codes to constants.

The special prefix handling is well-implemented with proper state update patterns to prevent unnecessary rerenders. The functional updates with prev state comparison effectively prevent the infinite rendering issue.

Consider extracting the special country codes and their corresponding data to named constants:

const SPECIAL_COUNTRIES = {
  SUPPORT: { flag: "📞", name: "Support", code: "1800" },
  OTHER: { flag: "🌍", name: "Other", code: "+" },
  UNKNOWN: { flag: "❓", name: "Unknown", code: "" }
} as const;

124-128: LGTM! Consider adding error boundary protection.

The empty value handling is well-implemented with a proper default country. However, the component could benefit from additional error protection.

Consider wrapping the component in an error boundary to gracefully handle any runtime errors:

class PhoneNumberFormFieldErrorBoundary extends React.Component {
  static getDerivedStateFromError(error: Error) {
    return { hasError: true };
  }
  
  render() {
    if (this.state?.hasError) {
      return <div className="text-danger-500">Failed to load phone input</div>;
    }
    return this.props.children;
  }
}

112-124: LGTM! Verify getCountryCode behavior for edge cases.

The country code determination logic is robust with proper null checks and fallbacks. The functional state updates prevent unnecessary rerenders.

Let's verify the behavior of getCountryCode for edge cases:

✅ Verification successful

The getCountryCode implementation handles edge cases well

The implementation is robust and handles several edge cases appropriately:

  • Validates + prefix before processing
  • Handles multiple matching countries by selecting the longest code
  • Special handling for shared country codes (like +1)
  • Returns undefined for unmatched numbers
  • Properly sanitizes codes by removing hyphens

The original review comment's approval was correct, and the implementation confirms that edge cases are properly handled. The function's behavior aligns well with the PhoneNumberFormField component's usage, which includes appropriate fallbacks when getCountryCode returns undefined.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for all usages and test cases of getCountryCode
ast-grep --pattern 'getCountryCode($_)' 

# Search for any existing test files
fd -g "*test*" -g "*spec*" | grep -i "phone"

Length of output: 373


Script:

#!/bin/bash
# Let's find the implementation of getCountryCode
ast-grep --pattern 'function getCountryCode($_) {
  $$$
}'

# Also search for any phone-related test files with a different pattern
fd "phone" -t f -e test.ts -e test.tsx -e spec.ts -e spec.tsx

# Search for the implementation in utils.ts directly
rg -A 10 "function getCountryCode" src/Utils/utils.ts

Length of output: 178


Script:

#!/bin/bash
# Let's try a different pattern to find the getCountryCode implementation
# It might be an exported const or arrow function
rg "getCountryCode.*=" src/Utils/utils.ts -A 10

# Also search for any exports of this function
rg "export.*getCountryCode" src/Utils/utils.ts

# Look for the function with surrounding context to understand its usage
rg "getCountryCode" src/Utils/utils.ts -B 5 -A 10

Length of output: 1783


Script:

#!/bin/bash
# Let's see the complete implementation of getCountryCode
# since the previous output was cut off
rg "export const getCountryCode" src/Utils/utils.ts -A 20

# Also check the CountryData type definition
rg "type CountryData" -A 5

Length of output: 969


Script:

#!/bin/bash
# Let's get the complete implementation with more context lines
rg "export const getCountryCode" src/Utils/utils.ts -A 30

# And let's check the phoneCodesJson content structure
rg "phoneCodesJson.*=" -A 5 src/Utils/utils.ts

Length of output: 1435
