Svelte 5 native support and other changes
Pre-release
This is a release candidate for svelte-maplibre 1.0. I believe everything is done but want to let it soak a bit before publishing.
See the demo site here.
This release not only upgrades to Svelte 5, but also integrates a few other breaking changes I've wanted to make:
- All the code in the package was moved to runes (thanks @benmccann for the nudge), so Svelte 5 is now required.
- Event handlers are now functions passed as props, in Svelte 5 style. The main difference that you will find is that instead of using
event.detail, the data for an event will just be present onevent. - Events no longer have the map attribute added to them since this is already present as
event.target - For anyone implementing their own layer components, the context structure has changed a lot. See
context.tsfor more details - Update deck.gl dependency to v9. Deck.gl's support for Mapbox and Maplibre is completely different between v8 and v9. This release does not change the interface in a breaking way, aside from the new version requirement. A future release will publish a new Deck.gl layer component which better integrates with the new support.
- Many of the uses of
nullin the package have been changed toundefined, which works better with Svelte's prop handling in some cases.
The old Svelte-4-compatible version will probably not get any new features, but for a while I will try to port significant bug fixes back to there as they are made.
