Question 1

How do I project WGS84 coordinates to Web Mercator in geojson2svg?

Accepted Answer

You need to use a coordinateConverter function with external libraries like reproject-spherical-mercator or proj4js, as the README states it doesn't handle projection automatically. This involves additional setup and dependency management.

Question 2

Can I use geojson2svg with React or Vue.js?

Accepted Answer

Yes, but since it outputs SVG strings, you'll need to parse them into DOM elements using libraries like parse-svg or React's dangerouslySetInnerHTML. It integrates well but requires extra steps for framework compatibility.

Question 3

What's the difference between geojson2svg and Leaflet for maps?

Accepted Answer

geojson2svg is a lightweight converter focused on generating SVG strings from GeoJSON, while Leaflet is a full-featured mapping library with tiles, interactions, and UI controls. Choose geojson2svg for custom SVG output without the overhead of a full map framework.

Question 4

How to style maps with geojson2svg?

Accepted Answer

Use the 'attributes' option to map GeoJSON properties to SVG attributes like 'class' or 'style', then apply CSS rules. The README shows examples with dynamic and static attribute mapping for basic styling.

Question 5

Is geojson2svg good for server-side rendering of maps?

Accepted Answer

Yes, it's well-suited for Node.js to generate SVG strings server-side, which can be cached or converted to images. However, you'll still need to handle projection manually if required.

Question 6

How to handle large GeoJSON files with geojson2svg?

Accepted Answer

The library processes features individually, but for performance, consider optimizing your GeoJSON or using the callback option to stream output. Large datasets might require memory management, though not explicitly detailed in the docs.
