Question 1

How to convert WKT to GeoJSON in JavaScript using wellknown?

Accepted Answer

Use the parse function: require('wellknown').parse('POINT(1 2)') returns a GeoJSON geometry object. It works in both Node.js and browsers, as shown in the README examples.

Question 2

wellknown vs wicket for WKT parsing?

Accepted Answer

wellknown is more lightweight and focused on WKT/GeoJSON conversion with no dependencies, while wicket might offer broader features but with more complexity. wellknown is better for minimal, fast conversions in JavaScript environments.

Question 3

Does wellknown support 3D geometries in WKT?

Accepted Answer

Yes, it supports 2D, 3D, and 4D geometries, as stated in the README. For example, parse('POINT Z (1 2 3)') will handle the Z coordinate for 3D points.

Question 4

How to install wellknown for browser use without npm?

Accepted Answer

You can use the standalone script by downloading wellknown.js directly via wget or include it via Bower. The README provides instructions for browserify or standalone usage.

Question 5

What error handling does wellknown provide for invalid WKT?

Accepted Answer

It returns null if parsing fails, and stringify throws errors for unsupported inputs like FeatureCollections. For production, you might need additional validation wrappers.

Question 6

Can wellknown handle large WKT files efficiently?

Accepted Answer

It's lightweight and should perform well for typical use cases, but for very large datasets, consider streaming or batch processing, as it processes strings directly without built-in optimizations.
