Introduction

This package simplifies phone number handling by wrapping Google's libphonenumber. While offering complete access to i18n.phonenumbers.PhoneNumber and i18n.phonenumbers.PhoneNumberUtil through getParsedPhoneNumber() and getPhoneNumberUtil(), it prioritizes ease of use. The constructor and getPhoneNumberInfo() provide a quick way to perform common tasks and access essential information. Designed to abstract frequently used features, this package welcomes user feedback and encourages feature requests.

Features

• Phone Number Parsing:
  • Parses phone numbers from various formats into a structured IPhoneNumber object.
  • Supports parsing with or without keeping the raw input.
  • Handles lenient parsing, allowing for punctuation, whitespace, and leading text.
• Phone Number Formatting:
  • Formats parsed phone numbers into E.164, international, national, and RFC3966 formats.
  • Formats numbers in their original format.
• Phone Number Information Retrieval:
  • Retrieves detailed information about a phone number, including:
    • Country code.
    • National number.
    • Number type (mobile, fixed-line, etc.).
    • Validity checks (possible, valid, valid for region).
    • Raw Input.
    • Region Code.
    • Extension.
• Phone Number Type Detection:
  • Identifies the type of phone number (mobile, fixed-line, toll-free, etc.).
• Validation:
  • Checks if a number is valid, possible, and valid for a region.
• As-You-Type Formatting:
  • Formats phone numbers in real-time as they are being typed.
  • Clears the input in the formatter.
• TypeScript Support:
  • Provides type definitions for enhanced development experience.

• Future Features:
  • ShortNumberInfo will be added in future releases.

Installation

npm install @arctics/google-phonelib

or

yarn add @arctics/google-phonelib

Usage

import {
  PhoneNumberHandler,
  PhoneNumberFormat,
  AsYouTypeHandler,
} from '@arctics/google-phonelib';

// Parsing and retrieving information
const handler = new PhoneNumberHandler('+12025550100', 'US');
const info = handler.getPhoneNumberInfo();

console.log(info.nationalNumber); // Output: 2025550100
console.log(info.countryCode); // Output: 1
console.log(info.numberType); // Output: FIXED_LINE_OR_MOBILE

// Formatting
const formattedNational = handler.format(PhoneNumberFormat.NATIONAL);
console.log(formattedNational); // Output: (202) 555-0100

const formattedE164 = handler.format(PhoneNumberFormat.E164);
console.log(formattedE164); // Output: +12025550100

//Original formatting
const originalFormat = handler.formatInOriginalFormat('US');
console.log(originalFormat);

// AsYouTypeHandler usage
const asYouTypeHandler = new AsYouTypeHandler('US');
console.log(asYouTypeHandler.typeNumber('202')); // Output: 202
console.log(asYouTypeHandler.typeNumber('555')); // Output: 202-555
console.log(asYouTypeHandler.typeNumber('0100')); // Output: (202) 555-0100
asYouTypeHandler.clearInput();

Notes

Unavailable methods and classes

The following methods or classes are unavailable on the original JS port of Google's libphonenumber:

• findNumbers - finds numbers in text (useful for highlighting or linking phone numbers inside text messages).
• PhoneNumberOfflineGeocoder - provides geographical information related to a phone number.
• PhoneNumberToCarrierMapper - provides carrier information related to a phone number.
• PhoneNumberToTimeZonesMapper - provides timezone information related to a phone number.

Metadata issues

Most of the issues submitted to this repository are related to carrier metadata - things like unexpected phone validations, errors in formatting numbers, unknown carriers and so on.

First, try the same input using the official demo page. If the result is different, then it might mean that a metadata update is due on this package, as the demo page always runs on the latest and official metadata version.

If the result is the same, it means there might be an issue with the currently available metadata. In that case, you should report your issue in the original project's issue tracker (moved out of GitHub on 05/12/2017).
