Question 1

How does Supercluster compare to Leaflet.markercluster?

Accepted Answer

Supercluster is a pure data processing library focused on performance and flexibility without built-in UI, while Leaflet.markercluster includes visualization components but may struggle with massive datasets. Supercluster can be integrated with any mapping library for custom rendering.

Question 2

How to integrate Supercluster with React for map clustering?

Accepted Answer

Load points in a useEffect hook, use Supercluster's getClusters method based on map viewport changes, and manage cluster data with React state to render markers dynamically. This approach keeps the UI responsive with large datasets.

Question 3

What happens if I need to update points in Supercluster dynamically?

Accepted Answer

You must create a new Supercluster instance and reload all points, as the index is immutable after loading. For frequent updates, this can cause performance overhead, so consider batching changes or using alternative libraries for real-time data.

Question 4

How to tune the nodeSize option for better performance?

Accepted Answer

Adjust nodeSize based on your dataset size; smaller values increase query precision but may slow performance, while larger values speed up queries at the cost of clustering accuracy. Experiment with benchmarks to find the optimal balance.

Question 5

Can Supercluster handle server-side rendering for map tiles?

Accepted Answer

Yes, it runs in Node.js and can generate clustered tiles using getTile() for pre-rendering or server-side processing, reducing client-side load and improving initial map performance in web applications.

Question 6

How to aggregate custom properties like sums or averages in clusters?

Accepted Answer

Use the map and reduce options to define functions that extract and merge properties, such as summing values, but ensure map returns a new object and reduce avoids mutating inputs to prevent bugs, as specified in the README.
