fullstack-phone ☎️

Master	Develop	npm	Libphonenumber version
			v8.10.6

fullstack-phone provides formatting, validation, and parsing of phone numbers per-region. The system is optimized for use as two modules:

a metadata server providing dynamic regional metadata
a lightweight, Closure-compiled phone client (26KB, 9KB gzipped)

This project was extended from Nathan Hammond's project, which itself is an adaptation of Google's libphonenumber library.

Installation

npm install fullstack-phone

Usage

Demo App: fullstack-phone-demo

The modules are optimized for use in two environments.

On the server (requires Node 4+):

// Node.js:
var phoneServer = require('fullstack-phone/server');

var metadata = phoneServer.loadMeta(['US', 'RU']); // load US and RU phone metadata
// now serve the metadata via some REST API or write it to a file for bundling with client code

On the client (assuming a client-side bundler that provides require, like webpack):

// Browser:
var phoneClient = require('fullstack-phone/client');

// fetch the metadata somehow, then pass to createPhoneHandler to instantiate a handler:
var phoneHandler = phoneClient.createPhoneHandler(metadata);

Once initialized, the phone handler can be used to process phone numbers:

// phone handler functions:

phoneHandler.getSupportedRegions(); // > ['US', 'RU']

phoneHandler.formatPhoneNumber(
  { countryCode: '1', nationalNumber: '5101234567'},
  { style: 'national'}
);
// > '(510) 123-4567'

phoneHandler.parsePhoneNumber('5101234567', 'US');
// > { countryCode: '1', nationalNumber: '5101234567' }

phoneHandler.validatePhoneNumber(
  { countryCode: '1', nationalNumber: '5101234567'},
  'US'
);
// > [Error: PHONE_INVALID_FOR_REGION]

It's also possible to use both within the same environment. Using the server module in the browser, however, nullifies the advantages of the per-region metadata slicing.

Why

Google’s libphonenumber library is the de-facto industry standard for processing international phone numbers, providing support for formatting, validating, and normalizing phone numbers in 250+ regions. However, the default phone metadata is quite heavy. Various custom JS packages have reduced the code & metadata footprint by:

Simplifying the API and pre-compiling with Closure (grantila/awesome-phonenumber)
Providing individually compiled code+metadata bundles for each region (leodido/i18n.phonenumbers.js, nathanhammond/libphonenumber)
Rewriting the entire library without Closure and providing the option to dynamically load metadata for groups of regions (catamphetamine/libphonenumber-js)

This package fills a different niche by providing:

The official libphonenumber code (not a pure JS re-write)
A small, static code base that doesn’t change for different regions
Pluggable metadata bundles for individual regions

Canonical Phone Object

When using Google libphonenumber directly, processing a phone number requires parsing a string or initializing a protocol buffer phone number object and calling setters for its various properties.

In contrast, fullstack-phone provides a more idiomatic JavaScript phone object, removing the need to call multiple setters. Most of the phone number functions here operate on a canonical phoneObj, as follows:

{
  countryCode : '1',
  nationalNumber : '5105551234',
  extension : '999'
}

countryCode
- Required. A number or string of digits representing a country phone code, e.g., '1'.
nationalNumber
- Required. A number or string of digits representing a phone number, as defined by E.164, e.g., '4085551212'.
- Note that this excludes the leading national prefix (or "trunk code"), which is 0 or 1 in most territories.
- Italian leading zeros should be included here.
extension
- Optional. A string representing the phone number extension, e.g., '123'.

Notes

For proper formatting and validation results, nationalNumber and countryCode must only contain digits. In addition, countryCode must be the calling code of a country for which the phone handler was initialized. (For example, if a phoneObj is passed with countryCode: 44, the phone handler must have been loaded with GB metadata for proper results.)

The phoneObj object can be created by calling parsePhoneNumber on a phone number string.

APIs

Server

var phoneServer = require('fullstack-phone/server');

The phone server exposes only one function:

loadMeta

`phoneServer.loadMeta(regionCodeArray)`

Given an array of two-letter region codes (ISO 3166-1 alpha-2), return a metadata bundle for those regions, to be passed to phoneClient.createPhoneHandler().

Notes:

If regionCodeArray is undefined, all regional metadata is returned.
loadMeta adds support for the following regions to Google libphonenumber:
- PN: Pitcairn Islands (copied from New Zealand metadata)
- AN: Netherlands Antilles (copied from Bonaire, Sint Eustatius and Saba)
Some regions depend on metadata of other regions. For example, the Bahamas (BS) shares a telephone country code (1) with the United States (US). Since the US is considered the main region for country code 1, the US metadata must be included to support processing of Bahamas phone numbers. loadMeta takes care of this automatically.

The full list of region codes supported is:

['001', 'AC', 'AD', 'AE', 'AF', 'AG', 'AI', 'AL', 'AM', 'AN', 'AO', 'AR', 'AS', 'AT', 'AU', 'AW', 'AX', 'AZ', 'BA', 'BB', 'BD', 'BE', 'BF', 'BG', 'BH', 'BI', 'BJ', 'BL', 'BM', 'BN', 'BO', 'BQ', 'BR', 'BS', 'BT', 'BW', 'BY', 'BZ', 'CA', 'CC', 'CD', 'CF', 'CG', 'CH', 'CI', 'CK', 'CL', 'CM', 'CN', 'CO', 'CR', 'CU', 'CV', 'CW', 'CX', 'CY', 'CZ', 'DE', 'DJ', 'DK', 'DM', 'DO', 'DZ', 'EC', 'EE', 'EG', 'EH', 'ER', 'ES', 'ET', 'FI', 'FJ', 'FK', 'FM', 'FO', 'FR', 'GA', 'GB', 'GD', 'GE', 'GF', 'GG', 'GH', 'GI', 'GL', 'GM', 'GN', 'GP', 'GQ', 'GR', 'GT', 'GU', 'GW', 'GY', 'HK', 'HN', 'HR', 'HT', 'HU', 'ID', 'IE', 'IL', 'IM', 'IN', 'IO', 'IQ', 'IR', 'IS', 'IT', 'JE', 'JM', 'JO', 'JP', 'KE', 'KG', 'KH', 'KI', 'KM', 'KN', 'KP', 'KR', 'KW', 'KY', 'KZ', 'LA', 'LB', 'LC', 'LI', 'LK', 'LR', 'LS', 'LT', 'LU', 'LV', 'LY', 'MA', 'MC', 'MD', 'ME', 'MF', 'MG', 'MH', 'MK', 'ML', 'MM', 'MN', 'MO', 'MP', 'MQ', 'MR', 'MS', 'MT', 'MU', 'MV', 'MW', 'MX', 'MY', 'MZ', 'NA', 'NC', 'NE', 'NF', 'NG', 'NI', 'NL', 'NO', 'NP', 'NR', 'NU', 'NZ', 'OM', 'PA', 'PE', 'PF', 'PG', 'PH', 'PK', 'PL', 'PM', 'PN', 'PR', 'PS', 'PT', 'PW', 'PY', 'QA', 'RE', 'RO', 'RS', 'RU', 'RW', 'SA', 'SB', 'SC', 'SD', 'SE', 'SG', 'SH', 'SI', 'SJ', 'SK', 'SL', 'SM', 'SN', 'SO', 'SR', 'SS', 'ST', 'SV', 'SX', 'SY', 'SZ', 'TA', 'TC', 'TD', 'TG', 'TH', 'TJ', 'TK', 'TL', 'TM', 'TN', 'TO', 'TR', 'TT', 'TV', 'TW', 'TZ', 'UA', 'UG', 'US', 'UY', 'UZ', 'VA', 'VC', 'VE', 'VG', 'VI', 'VN', 'VU', 'WF', 'WS', 'XK', 'YE', 'YT', 'ZA', 'ZM', 'ZW']

Note that '001' is used to load metadata for global numbers, such as 1-800 numbers.

Examples

var meta = phoneServer.loadMeta(['DE', 'AU']);
// > metadata object for DE and AU

var meta = phoneServer.loadMeta();
// > metadata object for all regions

Client

var phoneClient = require('fullstack-phone/client');

The phone client exposes only one function:

createPhoneHandler

`phoneClient.createPhoneHandler(metadata)`

Given a metadata bundle from phoneServer.loadMeta(), return a phone handler instantiated for that metadata.

Phone Handler

var phoneHandler = phoneClient.createPhoneHandler(metadata);

The phone handler returned by createPhoneHandler provides the following methods:

getSupportedRegions
countryCodeToRegionCodeMap
getCountryCodeForRegion
formatPhoneNumber
validatePhoneNumber
parsePhoneNumber
getExampleNumberForType
getAsYouTypeFormatter
- inputDigit
- clear

Exceptions

Any method that takes a regionCode string can throw the following exception if called with a region code for which the handler has not been initialized:

phoneHandler.getCountryCodeForRegion();
// > Error: Metadata not loaded for region: undefined

phoneHandler.getCountryCodeForRegion('XX');
// > Error: Metadata not loaded for region: XX

getSupportedRegions

`phoneHandler.getSupportedRegions()`

Return array of supported region codes.

Note that if a dependent region was loaded (such as the Bahamas), the main region for the shared country code is also reported a supported region (e.g., US).

Example

phoneHandler.getSupportedRegions();
// > ['US', 'RU']

countryCodeToRegionCodeMap

`phoneHandler.countryCodeToRegionCodeMap()`

Return map from country calling codes to array of supported regions.

Example

phoneHandler.countryCodeToRegionCodeMap();
// > { '1': [ 'US', 'BS' ], '7': [ 'RU' ] }

getCountryCodeForRegion

`phoneHandler.getCountryCodeForRegion(regionCode)`

Given a regionCode (assuming metadata has already been loaded for that region), return its country calling code as a number type.

Example

phoneHandler.getCountryCodeForRegion('RU');
// > 7

formatPhoneNumber

`phoneHandler.formatPhoneNumber(phoneObj, options)`

Given a phoneObj object and options object, return a formatted phone number as a string.

The options object has a single string property to indicate the formatting style desired:

{
    style: 'national' // or 'international', 'e164', 'rfc3966'
}

Examples

var phone = { countryCode: '1', nationalNumber: '5101234567' };

var options = { style: 'international' };
phoneHandler.formatPhoneNumber(phone, options);
// > '+1 510-123-4567'

options.style = 'national';
phoneHandler.formatPhoneNumber(phone, options);
// > '(510) 123-4567'

options.style = 'e164';
phoneHandler.formatPhoneNumber(phone, options);
// > '+15101234567'

options.style = 'rfc3966';
phoneHandler.formatPhoneNumber(phone, options)
// > 'tel:+1-510-123-4567'

validatePhoneNumber

`phoneHandler.validatePhoneNumber(phoneObj, regionCode)`

Given a phoneObj object and regionCode string, return an Error object indicating any problems with the phone object (or true if it passed validation).

The possible error messages are:

'PHONE_INVALID_FOR_REGION'
'PHONE_INVALID_COUNTRY_CODE'
'PHONE_NUMBER_TOO_LONG'
'PHONE_NUMBER_TOO_SHORT'
'PHONE_NUMBER_INVALID_LENGTH'
- Not too long, not too short, but not just right, either. For example, Andorra (AD) numbers are 6, 8, or 8 digits, so a 7-digit number yields this error.

Example

var phone = { countryCode: '1', nationalNumber: '5' };
phoneHandler.validatePhoneNumber(phone, 'US');
// > [Error: PHN_NUMBER_TOO_SHORT]

phone = { countryCode: '1', nationalNumber: '5105261234'};
phoneHandler.validatePhoneNumber(phone, 'US');
// true

parsePhoneNumber

`phoneHandler.parsePhoneNumber(phoneNumberToParse, regionCode)`

Given string parameters phoneNumberToParse and regionCode, return a phoneObj object or an Error object if the number is invalid.

The possible error messages are:

'PHONE_INVALID_COUNTRY_CODE'
'PHONE_NUMBER_TOO_SHORT'
'PHONE_NUMBER_TOO_LONG'
'PHONE_NOT_A_NUMBER'
'PHONE_TOO_SHORT_AFTER_IDD'

Example

phoneHandler.parsePhoneNumber('5101234567', 'US');
// > { countryCode: '1', nationalNumber: '5101234567' }

phoneHandler.parsePhoneNumber('ABC', 'US');
// > [Error: PHN_NOT_A_NUMBER]

getExampleNumberForType

`phoneHandler.getExampleNumberForType(type, regionCode)`

Given the string parameters type and regionCode, return a phoneObj object representing an example number for the given type.

The type parameter is an enum based on libphonenumber i18n.phonenumbers.PhoneNumberType and can be any of the following strings:

'FIXED_LINE'
'MOBILE'
'FIXED_LINE_OR_MOBILE'
'TOLL_FREE'
'PREMIUM_RATE'
'SHARED_COST'
'VOIP'
'PERSONAL_NUMBER'
'PAGER'
'UAN'
'VOICEMAIL'
'UNKNOWN'

Example

phoneHandler.getExampleNumberForType('MOBILE', 'US');
// > { countryCode: '1', nationalNumber: '2015550123' }

getAsYouTypeFormatter

`phoneHandler.getAsYouTypeFormatter(regionCode)`

Return a new AsYouTypeFormatter object instantiated for the given regionCode.

Example

var formatter = phoneHandler.getAsYouTypeFormatter('GB');
// > AsYouTypeFormatter object initialized to Great Britain

AsYouTypeFormatter methods

The initialized AsYouTypeFormatter object itself exposes the following methods:

inputDigit

`formatter.inputDigit(digit)`

Given a digit (number or string), output the phone number formatted thus far, given the history of inputted digits.

Note that digit can also be '+' or '*'

Example

formatter.inputDigit('5'); // > '5'
formatter.inputDigit('1'); // > '51'
formatter.inputDigit('0'); // > '510'
formatter.inputDigit('1'); // > '510-1'
formatter.inputDigit('2'); // > '510-12'
formatter.inputDigit('3'); // > '510-123'
formatter.inputDigit('4'); // > '510-1234'
formatter.inputDigit('5'); // > '(510) 123-45'
formatter.inputDigit('6'); // > '(510) 123-456'
formatter.inputDigit('7'); // > '(510) 123-4567'

clear

`formatter.clear()`

Clear the formatter state.

Example

formatter.inputDigit('5'); // > '5'
formatter.inputDigit('1'); // > '51'
formatter.inputDigit('0'); // > '510'
formatter.inputDigit('1'); // > '510-1'
formatter.inputDigit('2'); // > '510-12'
formatter.clear();
formatter.inputDigit('9'); // > '9'
formatter.inputDigit('1'); // > '91'
formatter.inputDigit('9'); // > '919'
formatter.inputDigit('4'); // > '919-4'
formatter.inputDigit('8'); // > '919-48'
