awesome-phonenumber

What is awesome-phonenumber?

The awesome-phonenumber npm package is a comprehensive library for parsing, formatting, and validating phone numbers. It supports a wide range of international phone number formats and provides utilities for handling phone number data effectively.

What are awesome-phonenumber's main functionalities?

Parsing Phone Numbers

This feature allows you to parse a phone number from a string and create a PhoneNumber object. The example demonstrates how to parse a US phone number.

const PhoneNumber = require('awesome-phonenumber');
const pn = new PhoneNumber('[phone]');
console.log(pn.getNumber()); // Outputs: [phone]

Formatting Phone Numbers

This feature allows you to format phone numbers in different formats such as E.164, international, and national. The example shows how to format a US phone number in various formats.

const PhoneNumber = require('awesome-phonenumber');
const pn = new PhoneNumber('[phone]');
console.log(pn.getNumber('e164')); // Outputs: [phone]
console.log(pn.getNumber('international')); // Outputs: [phone]
console.log(pn.getNumber('national')); // Outputs: [phone]

Validating Phone Numbers

This feature allows you to validate whether a phone number is valid or not. The example demonstrates how to check the validity of a US phone number.

const PhoneNumber = require('awesome-phonenumber');
const pn = new PhoneNumber('[phone]');
console.log(pn.isValid()); // Outputs: true

Getting Region Code

This feature allows you to get the region code of a phone number. The example shows how to retrieve the region code for a US phone number.

const PhoneNumber = require('awesome-phonenumber');
const pn = new PhoneNumber('[phone]');
console.log(pn.getRegionCode()); // Outputs: US

Getting Country Code

This feature allows you to get the country code of a phone number. The example demonstrates how to retrieve the country code for a US phone number.

const PhoneNumber = require('awesome-phonenumber');
const pn = new PhoneNumber('[phone]');
console.log(pn.getCountryCode()); // Outputs: 1

libphonenumber-js

libphonenumber-js is a simpler and smaller alternative to Google's libphonenumber library. It provides similar functionalities for parsing, formatting, and validating phone numbers. Compared to awesome-phonenumber, libphonenumber-js is more lightweight and may be preferable for projects where bundle size is a concern.

google-libphonenumber

google-libphonenumber is a comprehensive library developed by Google for parsing, formatting, and validating international phone numbers. It is the most feature-rich and widely used library for phone number handling. Compared to awesome-phonenumber, google-libphonenumber offers more extensive support and features but comes with a larger bundle size.

phone

The phone package is a simple library for parsing and formatting phone numbers. It is less feature-rich compared to awesome-phonenumber but provides basic functionalities for handling phone numbers. It is suitable for projects that require minimal phone number processing capabilities.

README

Awesome phonenumber parser

This library is a pre-compiled version of Google's libphonenumber, with a slightly simpler interface. It has a minimal footprint - is by far the smallest libphonenumber-based library available on npmjs, and has no dependencies.

TypeScript typings are provided within the package.

Uses libphonenumber v8.12.29

Comparison with other libraries

Since this library is pre-compiled, it doesn't depend on the closure compiler, and needs not load it on start. This makes the library faster and saves you a lot of space. It also means this library is trivial to use in any webpack project (or using any other means to run in the browser).

Among all the popular phone number using Google's libphonenumber (or mimicing it), only this one, google-libphonenumber and libphonenumber-js have decent README's with examples. This may have changed since first doing these benchmarks.

A library should be quick to load (require()), quick to parse first time and all consecutive times. It shouldn't bloat your node_modules, and it should have a small memory footprint, if possible.

The following is the result of a test program which loads the library, then parses a phone number, and then once again. It's called 100 times for each library and the mean values are shown here. Parsing a phone number first time might be slower because of initially compiling/optimizing regular expressions and whatnot. Parsing a phone number a second time will show the speed of likely all future parsing within that process.

Basic usage

var PhoneNumber = require( 'awesome-phonenumber' );

var pn = new PhoneNumber( '0707123456', 'SE' );
pn.isValid( );  // -> true
pn.isMobile( ); // -> true
pn.canBeInternationallyDialled( ); // -> true
pn.getNumber( );                   // -> '[phone]'
pn.getNumber( 'e164' );            // -> '[phone]' (default)
pn.getNumber( 'international' );   // -> '[phone]'
pn.getNumber( 'national' );        // -> '070-712 34 56'
pn.getNumber( 'rfc3966' );         // -> 'tel:[phone]'
pn.getNumber( 'significant' );     // -> '707123456'
pn.getRegionCode( );               // -> 'SE'
pn.getCountryCode( );              // -> 46

pn.toJSON( );                  // -> json blob, so that:
JSON.stringify( pn, null, 4 ); // -> This:
// {
//     "canBeInternationallyDialled": true,
//     "number": {
//         "input": "0707123456",
//         "international": "[phone]",
//         "national": "070-712 34 56",
//         "e164": "[phone]",
//         "rfc3966": "tel:[phone]",
//         "significant": "707123456"
//     },
//     "regionCode": "SE",
//     "valid": true,
//     "possible": true,
//     "type": "mobile",
//     "possibility": "is-possible"
// }

Detect country

When constructed with a phone number on e164 format (i.e. prefixed with a +), awesome-phonenumber will auto-detect the country:

PhoneNumber( '[phone]' ).getRegionCode( ); // -> 'SE'

API types

The API consists of the PhoneNumber class which sometimes uses enums. These are:

Phone number types

'fixed-line'
'fixed-line-or-mobile'
'mobile'
'pager'
'personal-number'
'premium-rate'
'shared-cost'
'toll-free'
'uan'
'voip'
'unknown'

Phone number possibilities

'is-possible'
'invalid-country-code'
'too-long'
'too-short'
'unknown'

Phone number formats

'international'
'national'
'e164'
'rfc3966'
'significant'

API functions

Library

var PhoneNumber = require( 'awesome-phonenumber' );

Country codes

There are conversion functions between the 2-character ISO 3166-1 region codes (e.g. 'SE' for Sweden) and the corresponding country calling codes.

PhoneNumber.getCountryCodeForRegionCode( regionCode );  // -> countryCode
PhoneNumber.getRegionCodeForCountryCode( countryCode ); // -> regionCode

Example

PhoneNumber.getCountryCodeForRegionCode( 'SE' ); // -> 46
PhoneNumber.getRegionCodeForCountryCode( 46 );   // -> 'SE'

Supported calling codes

PhoneNumber.getSupportedCallingCodes( ); // -> [ calling codes... ]

Supported region codes

PhoneNumber.getSupportedRegionCodes( ); // -> [ region codes... ]

Phone numbers

An instance of the PhoneNumber class will be created even if PhoneNumber is called as a function.

var pn = PhoneNumber( number, regionCode );
// is the same as
var pn = new PhoneNumber( number, regionCode );

PhoneNumber objects can also be created using the getExample( regionCode[, type ] ) function, see section Example phone numbers for country below.

pn.toJSON( );               // -> json blob as seen in "Basic usage" above
pn.isValid( );              // -> Boolean
pn.isPossible( );           // -> Boolean
pn.getType( );              // -> Any of the "Phone number types" defined above
pn.isMobile( );             // -> true if type is 'mobile' or 'fixed-line-or-mobile'
pn.isFixedLine( );          // -> true if type is 'fixed-line' or 'fixed-line-or-mobile'
pn.getNumber( [ format ] ); // -> Formatted number, see "Basic usage" for examples

// Returns the number formatted to how to dial it from another region.
pn.getNumberFrom( fromRegionCode );

Example

// Calling the Swedish number 0707123456 from Japan:
PhoneNumber( '0707123456', 'SE' ).getNumberFrom( 'JP' ); // '010 46 70 712 34 56'

Example phone numbers for country

Sometimes you want to display a formatted example phone number for a certain country (and maybe also a certain type of phone number). The getExample function is used for this.

PhoneNumber.getExample( regionCode[, phoneNumberType] ); // PhoneNumber object

The phoneNumberType is any of the types defined above.

Example

PhoneNumber.getExample( 'SE' ).getNumber( );                      // '[phone]'
PhoneNumber.getExample( 'SE', 'mobile' ).getNumber( );            // '[phone]'
PhoneNumber.getExample( 'SE', 'mobile' ).getNumber( 'national' ); // '070 123 45 67'

As-you-type formatting

You can use an AsYouType class to format a phone number as it is being typed. An instance of this class is retrieved by var ayt = PhoneNumber.getAsYouType( regionCode ), and has the following methods:

// Add a character to the end of the number
ayt.addChar( nextChar );

// Get the current formatted number
ayt.number( );

// Remove the last character
ayt.removeChar( );

// Replace the whole number with a new number (or an empty number if null)
ayt.reset( [ number ] );

// Get a PhoneNumber object representing the current number
ayt.getPhoneNumber( );

All the functions above except getPhoneNumber( ) return the current formatted number (as a String of course, as it may include spaces and other characters).

Example

var ayt = PhoneNumber.getAsYouType( 'SE' );
ayt.addChar( '0' ); // -> '0'
ayt.addChar( '7' ); // -> '07'
ayt.addChar( '0' ); // -> '070'
ayt.addChar( '7' ); // -> '070 7'
ayt.addChar( '1' ); // -> '070 71'
ayt.addChar( '2' ); // -> '070 712'
ayt.addChar( '3' ); // -> '070 712 3'
ayt.addChar( '4' ); // -> '070 712 34'
ayt.addChar( '5' ); // -> '070 712 34 5'
ayt.addChar( '6' ); // -> '070 712 34 56'
ayt.removeChar( );  // -> '070 712 34 5'
ayt.addChar( '7' ); // -> '070 712 34 57'
