Initial deck.gl support #37
Conversation
WalkthroughThis pull request introduces several new components and documentation related to the integration of deck.gl with MapLibre. It adds a new entry for the "deck.gl Overlay" example in the navigation menu, a Svelte component for visualizing map data using Deck.gl, and a markdown file for documentation. Additionally, a new overlay component is created for managing Deck.gl overlays on a MapLibre map, along with the necessary exports to make it available for use. Changes

For example, modify:
-$: { - layers; - if (deckOverlay) { - deckOverlay.setProps({ layers }); - } -}To:
$: if (deckOverlay) { deckOverlay.setProps({ layers }); }Repeat this change for each reactive statement, removing lines that reference the variables without any operation.

Let me gather more specific information about the example components' structure.
Let me try again without specifying the file type since 'svelte' isn't recognized.
Let me check the imports specifically to verify the patterns.
Let me try one more specific search to check the DeckGL example and similar complex examples.
Based on the gathered information, I can now provide the final response:
The DeckGL example follows project patterns correctly
The component follows the established patterns seen across other examples in the project:
- Uses TypeScript with
<script lang="ts"> - Follows consistent MapLibre component usage with proper class styling (
h-[60vh] min-h-[300px]) - Imports are organized similarly to other complex examples (Contour, Complex)
- Integration approach with deck.gl is clean and follows the same structure as other feature-rich examples

Replace '$effect' with Svelte reactive statements using '$:'
The $effect function used in the reactive blocks is not part of Svelte's standard API. In Svelte, reactive statements are declared using the $: label. Replace $effect blocks with reactive statements using $:.
Here's how you can modify the code:
For example, replace:
-$effect(() => {
- layers;
- if (!firstRun) {
- deckOverlay.setProps({ layers });
- }
-});With:
+$: if (deckOverlay) {
+ deckOverlay.setProps({ layers });
+}Repeat this replacement for each reactive block, updating effects, pickingRadius, parameters, layerFilter, and useDevicePixels accordingly:
+$: if (deckOverlay) {
+ deckOverlay.setProps({ effects });
+}
+$: if (deckOverlay) {
+ deckOverlay.setProps({ pickingRadius });
+}
+$: if (deckOverlay) {
+ deckOverlay.setProps({ parameters });
+}
+$: if (deckOverlay) {
+ deckOverlay.setProps({ layerFilter });
+}
+$: if (deckOverlay) {
+ deckOverlay.setProps({ useDevicePixels });
+}This ensures that the properties are updated reactively when their values change.

💡 Codebase verification
Documentation needed for deck.gl integration
While there is an example file (src/content/examples/deckgl-overlay/content.svelte.md), the component itself lacks proper documentation. Please add:
- JSDoc comments to the
DeckGLOverlay.sveltecomponent explaining its purpose and usage - Document the required deck.gl peer dependencies in the main README.md
- Consider expanding the example documentation to include basic setup instructions
🔗 Analysis chain
Consider documenting the new deck.gl integration.
Since this is a new public API for deck.gl integration, consider adding JSDoc comments or updating the README to document:
- The purpose and capabilities of the DeckGLOverlay component
- Any peer dependencies on deck.gl packages
- Basic usage examples
Let's check if documentation exists:

🛠️ Refactor suggestion
Simplify initialization logic by removing 'firstRun' variable
The firstRun variable is used to prevent reactive statements from executing before deckOverlay is initialized. However, you can simplify the code by checking if deckOverlay is defined in the reactive statements.
Modify your code as follows:
- let firstRun = true;Remove the $effect block that updates firstRun:
-$effect(() => {
- firstRun = false;
-});Update the reactive statements to check for deckOverlay:
-$: if (!firstRun) {
+$: if (deckOverlay) {
deckOverlay.setProps({ layers });
}Repeat this change for all reactive statements that depend on deckOverlay. This approach eliminates the need for the firstRun variable and simplifies the logic.

The addition of the optional source property is correct and necessary for proper layer configuration. This aligns with MapLibre's layer specification.
Let's verify existing usage to ensure this change doesn't impact current implementations:
✅ Verification successful
No impact on existing implementations - safe to proceed
The verification shows that all current usages of RasterLayer in the codebase are properly nested within their respective source components (ImageSource, CanvasSource, RasterTileSource, VideoSource). None of these implementations explicitly set the source property, as they inherit it from their parent source components. Therefore, making the source property optional is a safe enhancement that maintains backward compatibility while enabling standalone usage if needed.

6-6: Consider the trade-offs of static import
The switch from dynamic to static import of mlcontour will increase the initial bundle size. Consider whether lazy loading would be beneficial for performance, especially if this component isn't immediately needed on page load.
Let's check the bundle size impact:
✅ Verification successful
Let me gather more context about the usage of this component to better assess the trade-off between static and dynamic imports.
Let me check the dynamic imports in the route files to understand the project's code-splitting strategy.
Static import of mlcontour is appropriate here
The switch from dynamic to static import is justified because:
- The package size is relatively small (~10KB gzipped)
- The component is part of the main library exports in
index.tsand is used in example pages - The codebase already uses dynamic imports strategically for route-level code splitting
- The contour functionality is a core feature that would likely be needed whenever the map component is used

package.json (3)
3-3: LGTM: Version bump and deck.gl dependencies.
The version bump to 0.0.9 is appropriate for adding deck.gl support. The addition of deck.gl peer dependencies aligns with the PR objectives.
Also applies to: 41-42
57-57: Verify the impact of downgrading vite-plugin-svelte.
The dev dependency @sveltejs/vite-plugin-svelte has been downgraded from ^4.0.1 to ^4.0.0. While this is a minor downgrade, please ensure it doesn't affect the build process.
✅ Verification successful
Downgrading vite-plugin-svelte is safe in this context
The verification shows that despite the package.json specifying ^4.0.0, the project is actually using version 4.0.2 through pnpm resolution, and the setup is minimal and standard. The vite.config.js shows the plugin is used through SvelteKit's wrapper, which maintains compatibility across 4.x versions. The change from ^4.0.1 to ^4.0.0 won't impact the build process as both specify the same major version range.

43-43: Verify the impact of relaxed peer dependency constraints.
The peer dependencies for maplibre-contour and svelte have been made more permissive:
maplibre-contour:^0.0.8→>=0.0.0svelte:^5.0.0→>=5.0.0
While this provides more flexibility, it might lead to compatibility issues with future versions.
Also applies to: 46-46
✅ Verification successful
Relaxed peer dependency constraints are acceptable in this case
The relaxed version constraints for maplibre-contour appear safe because:
- It's used in a single file (
MapLibreContourSource.svelte) as a simple import - The package is a plugin/extension for MapLibre GL, which itself has proper version constraints (
^4.0.0 || ^5.0.0 || ^5.0.0-pre) - The library is in early development stages as stated in README ("
⚠️ This project is currently in the early stages of development")
For svelte, the >=5.0.0 constraint is also appropriate as:
- The README explicitly states "requires
svelte >= 5.0.0" - This is a Svelte component library that should work with any future Svelte 5+ version

💡 Codebase verification
Inconsistency found in source property implementation
The verification reveals inconsistencies in the implementation of the source property across layer components:
- Most layer components (SymbolLayer, RasterLayer, HillshadeLayer, LineLayer, FillExtrusionLayer, FillLayer, HeatmapLayer) correctly implement the optional
sourceproperty - CircleLayer and BackgroundLayer deviate from this pattern:
- CircleLayer is missing the
sourceproperty - BackgroundLayer omits
sourcefrom the type but doesn't reintroduce it
- CircleLayer is missing the
🔗 Analysis chain
LGTM! Verify consistency across layer components.
The addition of the optional source property is well-typed and aligns with the PR's objective of supporting deck.gl integration. The change provides necessary flexibility while maintaining type safety.
Let's verify that this pattern is consistently applied across all layer components:

💡 Codebase verification
Inconsistency found in CircleLayer and BackgroundLayer components
The verification reveals that while most layer components consistently implement the optional source property, there are two inconsistencies:
CircleLayer.svelteis missing thesource?: stringpropertyBackgroundLayer.svelteis missing thesource?: stringproperty (though this might be intentional as background layers typically don't need a source)
🔗 Analysis chain
LGTM! Verify consistency across layer components.
The addition of the optional source property is well-implemented and maintains type safety. The change enhances the component's configurability while following TypeScript and Svelte conventions.
