Question 1

RBush vs kdbush: which is better for my project?

Accepted Answer

Use RBush for dynamic datasets with insertions and deletions, as it supports updates. For static point data, kdbush is 5-8x faster, as mentioned in the README, so choose based on data mutability.

Question 2

How to use RBush with custom coordinate formats?

Accepted Answer

Extend the RBush class and override methods like toBBox, compareMinX, and compareMinY. For example, to handle [x, y] arrays, define toBBox to return a bounding box, as shown in the documentation with MyRBush.

Question 3

Does RBush work in modern browsers and Node.js?

Accepted Answer

Yes, RBush v4+ is published as an ES module and works universally in modern browsers and Node.js. However, for IE11 or older environments, you need to transpile the code yourself, as noted in the compatibility section.

Question 4

What's the impact of nodeSize on RBush performance?

Accepted Answer

NodeSize controls the maximum entries per node; higher values (e.g., 16) make insertion faster but search slower, and vice versa. The default is 9, which balances both for most applications, as explained in the README.

Question 5

How to handle large datasets with RBush efficiently?

Accepted Answer

Use bulk loading for initial indexing to gain a 20-30% query performance boost. For updates, prefer bulk insertion for clustered data, but avoid it for scattered data to prevent performance degradation, per the README notes.

Question 6

Is RBush good for real-time collision detection?

Accepted Answer

Yes, RBush is excellent for real-time collision detection due to its fast search and collides methods. It's commonly used in interactive maps and games where quick spatial queries are essential.

Question 7

Can I use RBush with TypeScript?

Accepted Answer

RBush is written in JavaScript, but it can be used with TypeScript. You might need to add type definitions or use community-provided ones, as the library doesn't include built-in TypeScript support.
