Question 1

How do I use JSTS with Node.js?

Accepted Answer

Install via npm install jsts, then import individual ES modules. Be aware of Node.js ESM interoperability requirements, as JSTS is delivered only as ES modules, which may need configuration for CommonJS environments.

Question 2

JSTS vs Turf.js for geometric operations?

Accepted Answer

JSTS is a direct port of JTS with a Java-like API and OGC compliance, ideal for JTS familiarity or standards-heavy projects. Turf.js is a native JavaScript library with a modern API, better for lightweight, JS-centric workflows without Java baggage.

Question 3

How to avoid TopologyException errors in JSTS?

Accepted Answer

Reduce precision in input geometries using GeometryPrecisionReducer and ensure they are valid per OGC standards. This minimizes calculation failures due to floating-point issues, as mentioned in the caveats.

Question 4

Does JSTS support 3D geometries?

Accepted Answer

No, JSTS is based on the 2D Simple Features Specification, so it only handles 2D geometries. For 3D operations, consider other libraries or server-side solutions.

Question 5

How to perform a buffer operation on a GeoJSON geometry with JSTS?

Accepted Answer

Use the GeoJSONReader to parse the geometry, then access the buffer method from the appropriate operation class, since shortcut methods are not available in all builds without monkey patching.

Question 6

Can I use JSTS without a bundler in modern browsers?

Accepted Answer

Yes, by including the ES6 build from a CDN as a script tag, but for module-based projects, a bundler is recommended. The ES5 build is also available for broader browser compatibility.
