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.
