## What it is
A collection of utility libraries for the Google Maps JavaScript API v3, including marker clustering, marker management, and dynamic API loading. All packages have been moved to individual repositories under the @googlemaps NPM scope, and this monorepo is archived.

## Use cases
- cluster nearby map markers
- load google maps api dynamically with a promise
- show and hide markers based on zoom level
- add labels to google maps markers
- add wms layers to google maps

## When to choose
- you need a legacy utility from this repo and are pinned to the old package names
- you want to trace the history of a googlemaps utility before it moved to its own repo

## When to avoid
- starting a new project - use the individual @googlemaps scoped packages instead
- you need maintained code with recent releases
- you need one of the archived, never-published packages like InfoBox or RouteBoxer

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, developer-tools
- domain: web-development, frontend
- platform: browser
- tags: google-maps, maps-api, marker-clustering, monorepo-archive, typescript, maps, javascript, nodejs
