Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Description

The library creates and manages per-zoom-level clusters for large amounts of markers.

Try the demo

See the history section and migration section for how this library relates to @google/markerclusterer and @googlemaps/markerclustererplus.

Install

Available via npm as the package @googlemaps/markerclusterer.

npm i @googlemaps/markerclusterer

Alternativly you may add the umd package directly to the html document using the unpkg link.

<script src="https://unpkg.com/@googlemaps/markerclusterer/dist/index.min.js"></script>

When adding via unpkg, the MarkerClusterer can be accessed at markerClusterer.MarkerClusterer.

TypeScript

This library uses the official TypeScript typings for Google Maps Platform, @types/google.maps.

npm i -D @types/google.maps

Documentation

The reference documentation is generated from the TypeScript definitions.

Examples

import { MarkerClusterer } from "@googlemaps/markerclusterer";

// use default algorithm and renderer
const markerCluster = new MarkerClusterer({ map, markers });

View the package in action:

  • Algorithm Comparisons - This example demonstrates the different algorithms. Please note that spacing and many other options can be changed for each algorithm.

  • Renderer Usage - This example demonstrates different renderers similar to the image below.

History

This library has a heritage in @google/markerclusterer and @googlemaps/markerclustererplus, originally made available on code.google.com and then transferred to GitHub at https://github.com/googlemaps/v3-utility-library. The following is an approximate timeline.

Migration

The API of @googlemaps/markerclusterer has changed in a number of ways from @googlemaps/markerclustererplus.

  • The MarkerClusterer class now accepts an algorithm and renderer parameter to allow for more flexibility. The interface looks like the following:
{
    algorithm?: Algorithm;
    map?: google.maps.Map;
    markers?: google.maps.Marker[];
    renderer?: Renderer;
    onClusterClick?: onClusterClickHandler;
  }
  • The MarkerClusterer accepts a single options argument instead of positional parameters.
  • The traditional GridAlgorithm is still supported, but is not the default. The default is supercluster which uses k-d trees for improved performance.
  • Styling of clusters has been simplifed and moved to the renderer interface.
  • The MarkerClusterer class is still an instance of google.maps.OverlayView, but uses google.maps.Markers instead of google.maps.Overlay to render the clusters. This solves issues related to the usage of map panes and click handlers.
  • @googlemaps/markerclusterer supports Marker and Map a11y improvements.
