Question 1

How to add custom markers to svelte-maplibre maps?

Accepted Answer

svelte-maplibre doesn't provide built-in marker components; you'll need to access the MapLibre instance via bindings and use native methods to manage markers manually. Check the demo site for examples, but expect to handle Svelte reactivity yourself for dynamic updates.

Question 2

svelte-maplibre vs react-map-gl for Svelte projects?

Accepted Answer

svelte-maplibre is tailored for Svelte with reactive bindings, while react-map-gl is for React. If you're committed to Svelte, svelte-maplibre offers better integration, but it's less mature than react-map-gl's ecosystem and documentation.

Question 3

How to handle map click events in svelte-maplibre?

Accepted Answer

Bind to the map instance and use MapLibre's event system—set up listeners on the map object after load and update Svelte reactive variables. The demo site likely includes event handling examples, but documentation is sparse.

Question 4

Does svelte-maplibre support server-side rendering with SvelteKit?

Accepted Answer

Yes, it works with SvelteKit, but maps rely on WebGL, so use client-side components to avoid SSR issues. Import it in +page.svelte or similar files to ensure it only runs in the browser.

Question 5

How to dynamically change map style in svelte-maplibre?

Accepted Answer

Leverage Svelte's reactivity by binding the style prop to a variable—update the URL or style object, and the MapLibre component will reflect changes automatically, as implied by its reactive design.

Question 6

svelte-maplibre performance with large geospatial datasets?

Accepted Answer

Performance hinges on MapLibre's WebGL engine; for large datasets, optimize with vector tiles and efficient layer management. svelte-maplibre adds minimal overhead, but complex state changes might trigger re-renders if not handled carefully.

Question 7

How to install svelte-maplibre and set up a basic map?

Accepted Answer

Install via npm with 'npm install svelte-maplibre', import the MapLibre component, and configure props like center, zoom, and style. Remember to set CSS for the container height, as shown in the README's usage snippet.
