RBush is a high-performance JavaScript library providing a 2D spatial index for points and rectangles, built on an optimized R*-tree with bulk loading and insertion. It enables fast bounding-box queries, commonly used in maps and data visualizations.

Use cases

• find all items within a bounding box quickly
• spatial indexing for map features
• collision detection for rectangles
• speed up hit-testing in canvas visualizations
• index geographic points for clustering
• bulk-load thousands of rectangles and query them

When to choose

• you need fast 2D rectangle or point queries in JavaScript
• you have large datasets where linear scanning is too slow
• you want a dependency-free, well-tested spatial index

When to avoid

• you need 3D or higher-dimensional indexing
• you need nearest-neighbor or k-d tree style queries out of the box
• you work outside JavaScript
