## What it is
A zero-dependency Node.js wrapper around Google's libphonenumber library for parsing, formatting, storing, and validating international phone numbers. It makes the Closure-compiled JavaScript port of libphonenumber easy to require and use in Node.js projects.

## Use cases
- validate international phone numbers in a node.js app
- parse raw phone number strings into country code and national number
- format phone numbers as E.164 or RFC3966
- standardize user-entered phone numbers before storing them
- look up carrier and region metadata for a phone number
- normalize phone numbers for SMS sending

## When to choose
- you need Google's libphonenumber functionality in Node.js without fighting the Closure library
- you want a zero-dependency, regularly updated phone number library
- you need reliable international phone parsing, formatting, and validation server-side

## When to avoid
- you are not on Node.js (use the official libphonenumber ports for Java, C++, or the browser directly)
- you only need lightweight country-code validation and want a smaller library
- you need TypeScript types out of the box (they live in a separate @types package)

## Facets
- artifact type: library
- maturity: active
- function: parser, serialization, developer-tools
- domain: developer-tools, web-development, backend
