Phone Utility

Utility to validate phone numbers (US Only), parse, or format.

Check if Phone Number is Syntactically Correct (US Format)

``typescript
import PhoneUtil from "@nems.org/phone-utility";
// Or Import like below
// import {PhoneUtility} from "@nems/phone-utility"

let phone = "+1 (333) 555-7777";

let badPhone = "+1 (123) 123-4567";

PhoneUtil.isValidAmericanPhoneNumber(phone);
// returns true

PhoneUtil.isValidAmericanPhoneNumber(badPhone);
// returns false, Area Code cannot start with 1 and neither can telephone (first 3 digits after area code)
`

Parse Phone Number

Parse a phone number into parts. Currently only supports US/Canada Phones

`typescript
import PhoneUtil, { ParsedPhone } from "@nems.org/phone-utility";
// Or Import As Below
// import {PhoneUtility} from "@nems/phone-utility"

let phone = "+1 (333) 555-7777";

PhoneUtil.parsePhone(phone);
/*
returns a ParsedPhone
{
areaCode: "333";
telephone: "5557777";
countyCode: "1";
telephoneDigitGroups: ["555", last4: "7777"];
}
*/

let phoneNoCountry = "333-555-7777";

PhoneUtil.parsePhone(phone);
/*
returns a ParsedPhone
{
areaCode: "333";
telephone: "5557777";
countyCode: "1"; // inferred as US/Canada
telephoneDigitGroups: ["555", last4: "7777"];
}
*/
`

Format Phone Number

Format phone numbers using tokens. Digits are represented as hash/pound signs (#). Other tokens are treated as literals and will render in place.

`typescript
import PhoneUtil from "@nems.org/phone-utility";

const phone = "3335557777";

PhoneUtil.formatPhoneNumber(phone, "+# (###) ###-####");
// returns "+1 (333) 555-7777"
PhoneUtil.formatPhoneNumber(phone, "+###########");
// returns "+13335557777"
PhoneUtil.formatPhoneNumber(phone, "###.###.####");
// returns "333.555.7777"
