feat(maplibre): add scale, geolocate, fullscreen, attribution controls - #910
Merged

Conversation
Only NavigationControl had a component, so every other standard control went through `@ready` with a manual addControl and removeControl (PC-15). Each new component follows ScriptMapLibreNavigationControl: `position` and `options` props, add on map ready, remove on unmount, options read once. ScaleControl also forwards `unit` through `setUnit()`. GeolocateControl re-emits every control event and emits `unavailable` when permission was denied before load, which MapLibre only logs. AttributionControl replaces the map's default control and restores it on unmount, so attribution shows once and required credits never disappear.

`@packages/script/src/runtime/components/MapLibre/ScriptMapLibreAttributionControl.vue`:
- Around line 42-44: Update the cleanup logic around map.hasControl(instance) so
a missing control is not treated as evidence that the map was removed. Track map
removal through a separate lifecycle check, and when the map remains active,
restore the controls stored in replaced instead of discarding them.
- Line 26: Update the control replacement logic around the AttributionControl
instance creation so existing map-level customAttribution is retained when
props.options does not define it. Reuse the map’s configured attribution while
constructing the replacement, without overriding an explicitly provided
component value.

The replacement control ignored `customAttribution` set through the map's `attributionControl` option, so those credits vanished while mounted. Cleanup also treated a missing component control as a removed map, so a consumer who removed it by hand lost the default attribution for good. It now checks `map._removed` instead.

# Conflicts: # packages/script/src/registry-types.json
A control template held only a comment. A production build strips it, so the server rendered nothing while the client expected a comment node, and hydration reported a mismatch. `nuxt dev` keeps comments and hid the bug. A `render` returning `null` yields a comment on both sides. The new e2e test compiles with `comments: false`, because the Vitest worker loads the development Vue compiler, which keeps comments.

MapLibre GL JS 6.9.1 Map.addControl source _controls multiple controls AttributionControl
💡 Result:
<search_synthesis>
In MapLibre GL JS 6.9.1, the map._controls property is an internal array used by the Map instance to track all active controls currently added to the map [1][2]. While you can inspect this array to see which controls are registered, it is intended for internal use rather than public API manipulation [3]. To manage controls, including adding and removing them, you should use the documented public methods map.addControl and map.removeControl [1][4]. Handling Multiple Controls and AttributionControl You can add multiple controls to a map instance by calling map.addControl repeatedly [1][5]. Each call can specify a different position (e.g., 'top-left', 'top-right', 'bottom-left', 'bottom-right') [1]. When working with the AttributionControl specifically: 1. By default, an attribution control is added automatically [1]. 2. If you want to customize or reposition it, you can disable the default by setting attributionControl: false in the Map constructor, then manually add your own instance using map.addControl [6][7]. 3. Multiple controls can coexist in the same position; the map will stack them based on the order in which they were added [1]. Example of adding custom controls: // Disable default attribution if needed const map = new maplibregl.Map({ container: 'map', style: '...', attributionControl: false }); // Add custom attribution control at a specific position map.addControl(new maplibregl.AttributionControl({ compact: true }), 'top-left'); // Add other controls as needed map.addControl(new maplibregl.NavigationControl, 'top-right'); If you need a more advanced layout to manage many controls, such as a grid or toolbar, consider using third-party community libraries like maplibre-gl-components, which provide utilities to organize multiple controls efficiently [8][9].

Preserve custom attribution from every replaced control.
When multiple MapLibre.AttributionControl instances exist, this code removes all controls in replaced but reads customAttribution only from replaced[0]?.options. If a later control defines custom attribution and props.options.customAttribution is unset, that credit disappears while this component is mounted. Aggregate the customAttribution values from every replaced control before creating the replacement.

Only
ScriptMapLibreNavigationControlhad a component. Every other standard control needed@ready, a manualaddControl, and a manualremoveControl.This adds four components that follow

MapLibre adds a default attribution control to every map. A second control would duplicate it. Removing it would strip required OpenFreeMap and OpenStreetMap credits.
AttributionControland adds its own.map._removed), it restores nothing. If consumer code removed the component's control, it still restores the default.optionsoverride the default control's options. Credits from every replaced control, includingattributionControl.customAttribution, stay unless the component sets its own.optionscannot remove source attribution from the style.It finds the default control through
map._controls, which is typed inmaplibre-gl.d.tsand is the listhasControl()reads.Hydration fix for all five controls, including NavigationControl
