Pros of libphonenumber

• More comprehensive and actively maintained by Google
• Supports a wider range of phone number formats and countries
• Offers additional features like carrier lookup and time zone detection

Cons of libphonenumber

• Larger library size, which may impact performance in some applications
• More complex API, potentially requiring a steeper learning curve
• Higher memory usage due to extensive metadata

Code Comparison

libphonenumber:

from phonenumbers import parse, format_number, PhoneNumberFormat

number = parse("+1 650-253-0000", None)
formatted = format_number(number, PhoneNumberFormat.INTERNATIONAL)

phonenumbers:

import phonenumbers

number = phonenumbers.parse("+1 650-253-0000", None)
formatted = phonenumbers.format_number(number, phonenumbers.PhoneNumberFormat.INTERNATIONAL)

Both libraries offer similar basic functionality for parsing and formatting phone numbers. However, libphonenumber provides more advanced features and broader support for international numbers, while phonenumbers aims to be a lighter-weight alternative with a focus on core functionality.

Pros of python-phonenumbers

• More comprehensive and actively maintained
• Supports a wider range of phone number formats and countries
• Better documentation and examples

Cons of python-phonenumbers

• Larger package size, which may impact performance
• More complex API, potentially steeper learning curve

Code Comparison

python-phonenumbers:

import phonenumbers

number = phonenumbers.parse("+1 650 253 0000", None)
print(phonenumbers.is_valid_number(number))
print(phonenumbers.format_number(number, phonenumbers.PhoneNumberFormat.INTERNATIONAL))

phonenumbers:

from phonenumbers import parse, is_valid_number, format_number, PhoneNumberFormat

number = parse("+1 650 253 0000", None)
print(is_valid_number(number))
print(format_number(number, PhoneNumberFormat.INTERNATIONAL))

The code usage is very similar between the two libraries, with python-phonenumbers offering a slightly more intuitive import structure. Both libraries provide similar functionality for parsing, validating, and formatting phone numbers. However, python-phonenumbers generally offers more advanced features and better support for edge cases and international numbers.

Pros of libphonenumber-for-php

• More comprehensive and feature-rich, offering a wider range of functionalities
• Better maintained with more frequent updates and contributions
• Closer to the original Google's libphonenumber implementation

Cons of libphonenumber-for-php

• Larger codebase and dependencies, potentially leading to a heavier footprint
• May be more complex to use and integrate for simpler use cases
• Requires more system resources due to its comprehensive nature

Code Comparison

libphonenumber-for-php:

$phoneUtil = \libphonenumber\PhoneNumberUtil::getInstance();
$phoneNumber = $phoneUtil->parse("+1-202-555-0123", "US");
$isValid = $phoneUtil->isValidNumber($phoneNumber);

phonenumbers:

$phone = \Nyaruka\PhoneNumbers\PhoneNumber::parse("+1-202-555-0123");
$isValid = $phone->isValid();

Both libraries provide similar functionality for parsing and validating phone numbers. However, libphonenumber-for-php offers a more extensive API with additional methods and options, while phonenumbers provides a simpler, more straightforward approach for basic use cases.

The choice between these libraries depends on the specific requirements of your project, considering factors such as feature set, performance, and ease of use.

Pros of libphonenumber-js

• Lightweight and optimized for browser usage
• Supports tree-shaking for reduced bundle size
• Provides a simpler API for basic phone number operations

Cons of libphonenumber-js

• Less comprehensive coverage of phone number formats and metadata
• May not be as up-to-date with the latest phone number changes
• Limited support for certain advanced features available in phonenumbers

Code Comparison

phonenumbers:

import phonenumbers

number = phonenumbers.parse("+12125552368", None)
print(phonenumbers.is_valid_number(number))
print(phonenumbers.format_number(number, phonenumbers.PhoneNumberFormat.INTERNATIONAL))

libphonenumber-js:

import { parsePhoneNumber } from 'libphonenumber-js'

const number = parsePhoneNumber('+12125552368')
console.log(number.isValid())
console.log(number.format('INTERNATIONAL'))

Both libraries provide similar functionality for parsing and formatting phone numbers, but with different syntax and method names. phonenumbers offers a more extensive set of features, while libphonenumber-js focuses on simplicity and browser optimization.

Pros of intl-tel-input

• User-friendly interface with country flag dropdown and automatic formatting
• Lightweight and easy to integrate into web applications
• Extensive customization options for appearance and behavior

Cons of intl-tel-input

• Limited to client-side validation and formatting
• Requires additional server-side validation for complete phone number verification
• May not be suitable for non-web-based applications

Code Comparison

intl-tel-input:

$("#phone").intlTelInput({
  utilsScript: "path/to/utils.js",
  preferredCountries: ["us", "gb"],
  separateDialCode: true
});

phonenumbers:

import phonenumbers

number = phonenumbers.parse("+12125552368", None)
print(phonenumbers.is_valid_number(number))
print(phonenumbers.format_number(number, phonenumbers.PhoneNumberFormat.INTERNATIONAL))

intl-tel-input focuses on providing a user-friendly input interface for phone numbers, while phonenumbers offers more comprehensive parsing, validation, and formatting capabilities. intl-tel-input is ideal for web-based applications requiring an intuitive user interface, whereas phonenumbers is better suited for backend processing and cross-platform applications needing robust phone number handling.
