googlemaps/v3-utility-library

The v3‑utility‑library hosts reusable JavaScript helper libraries—such as marker clustering, script loading, and OGC support—that extend the Google Maps JavaScript API v3 for more efficient and feature‑rich web mapping applications. It is aimed at developers who want to simplify common Map tasks (e.g., clustering markers, managing async script loading) without building those utilities from scratch. Access to the code and documentation is provided via the @googlemaps npm packages and the archived GitHub repository.
