The full example with code snippets can be found at this GitHub repository.

Introduction

If you want to create a custom marker style like Airbnb, dynamically display information, and render custom React components when users interact with it, you’ve come to the right place.

This example attempts to implement Google Map features using the official Google React Wrapper library, with the goal of customizing MapOverView to add complex Markers on the Map, such as expanding listings like Airbnb. This example will support Marker Clustering.

This example integrates Google Map’s official package with Next.js.

Getting Started

Follow these steps to create a project and install the required dependencies.

Obtaining the Google Map API Key

Refer to the official Google tutorial to obtain the API key.

Creating a Map Container Component

Create a MapContainer component to display the map.

Creating a Map Component

Create a Map component to handle the initialization of the Map and Markers.

Basic Implementation

You have now implemented the basic functionality.

Using MapOverView to Customize Marker

We will use the OverlayView class instead of a regular Marker to create custom markers. Create a MapOverlayView component to help create Google Map’s OverlayView.

Creating MapMarker and Child Components

Next, create the MapMarker component and its content using the MapOverlay component.

Advanced — Supporting Cluster (Aggregation)

To support clustering, use the official library.

Integrating MarkerClusterer

Now integrate MarkerClusterer into the example by adding it to the Map component.

Finally, pass the cluster to the MapMarker and then to the MapOverlay.

That’s it! You’ve now implemented a custom Google Map with clustering support in React.
