react-phone-input-2 country.format not working

If you're using the react-phone-input-2 library in your React application and you're experiencing issues with the country format not working, you're not alone. This problem can often lead to confusion and frustration, especially when building a user-friendly phone input field.

The Original Problem

Here is a snippet of the original code that exemplifies the problem scenario:

import React from 'react';
import PhoneInput from 'react-phone-input-2';
import 'react-phone-input-2/lib/style.css';

function PhoneNumberInput() {
  return (
    <PhoneInput 
      country={'us'} 
      onChange={phone => console.log(phone)} 
      specialLabel="Your phone" 
    />
  );
}

export default PhoneNumberInput;

In this scenario, developers find that despite setting the country, the format of the phone number does not appear as expected.

Understanding the Issue

Why the Country Format May Not Work

The issue with the country format not functioning correctly might be due to several reasons, including:

Missing Dependencies: Sometimes, libraries require additional dependencies or styles to work correctly.
Improper Usage: If the PhoneInput component is not correctly implemented or configured, it can lead to formatting issues.
Version Compatibility: Changes in library versions may introduce breaking changes that could affect how the country format functions.

Solutions to Try

Install Required Dependencies: Ensure that you have installed the react-phone-input-2 library and its associated CSS files.
```
npm install react-phone-input-2
```
Check Your Implementation: Verify that you’re passing all necessary props to the PhoneInput. For instance, ensure you are setting the country prop to a valid country code.
Update Your Library: If you're using an older version of react-phone-input-2, consider updating it to the latest version to benefit from recent fixes and improvements:
```
npm update react-phone-input-2
```
Inspect CSS Styles: Sometimes the issue may not be with the functionality but rather with the CSS. Ensure that your styles are properly linked, and inspect the element in the browser to see if any styles are conflicting.

Practical Example

Here's an improved example of the PhoneNumberInput component that addresses potential issues:

import React from 'react';
import PhoneInput from 'react-phone-input-2';
import 'react-phone-input-2/lib/style.css';

function PhoneNumberInput() {
  const handlePhoneChange = (value) => {
    console.log(value);
  };

  return (
    <div>
      <label>Your Phone Number</label>
      <PhoneInput
        country={'us'}
        value={''}
        onChange={handlePhoneChange}
        inputStyle={{
          width: '100%',
          padding: '10px',
          borderRadius: '5px',
          border: '1px solid #ccc',
        }}
        specialLabel=""
      />
    </div>
  );
}

export default PhoneNumberInput;

Additional Considerations

Custom Validation: You might want to implement custom validation logic to ensure that the phone number input adheres to specific formats or requirements.
User Experience: Make sure your input has clear labels and instructions to provide better user experience.

Conclusion

If you're facing issues with the country.format in react-phone-input-2, remember to check your dependencies, implementation, and CSS styles. By following the steps and solutions mentioned above, you can ensure that your phone input works seamlessly for users across various countries.
