leaflet.extras2 1.3.4.9000

leaflet.extras2 1.3.4 (2026-09-16)

• Stop importing grDevices in NAMESPACE and drop it from Suggests.
• Uptade GitHub Actions to actions/checkout@v6

leaflet.extras2 1.3.3 (2026-09-09)

• Included Leaflet.VectorGrid for tiled GeoJSON (addVectorgrid()) and protobuf vector tiles (addProtobuf()). addProtobuf() accepts popup and label as property names (not formulas): click popup and hover tooltip. Hovering point features (place/street labels) no longer crashes Leaflet (getLatLng / lat undefined). Examples: inst/examples/vectorgrid_app.R and inst/examples/vectorgrid_pbf_app.R. Tests cover Spatial/GeoJSON/URL inputs and missing sf / yyjsonr.
• spinWhile() shows a map spinner in Shiny around server work. startSpinner()/stopSpinner() in one renderLeaflet() chain cannot do that. The spinner stays visible until the work finishes. Fixes #48.
• Sidebar no longer steals clicks or wheel events from Shiny inputs (selectInput / Selectize, including Firefox). While a dropdown is open the map ignores pointer events. Fixes #78, #66.
• addWMS() now hides its attribution when the layer group is hidden, matching leaflet::addWMSTiles().
• addWMS(headers = ...) sends Authorization (Basic/Bearer) and other custom headers with tiles, the overlay image and GetFeatureInfo (#54). The WMS must allow CORS for those headers. GetFeatureInfo no longer opens a blocked iframe on 401/403; it shows an unauthorized message. Example: inst/examples/wms_geoserver_app.R.
• setWMSParams() updates WMS request parameters (e.g. time) on an existing layer via leafletProxy(), so Shiny apps no longer need to rebuild the map (#52).
• addWMS() GetFeatureInfo popups work behind HTTPS reverse proxies: HTTP→HTTPS redirects (301/302) are followed on the same host, and http:// WMS URLs are upgraded on HTTPS pages (#14).
• Replaced deprecated structure(..., .Label = ) with levels = in tests (test-mapkeyicon.R, test-playback.R) to clear the R-devel NOTE.
• Documented Shiny mouse events for addAntpath(): use input$MAPID_antpath_click / _mouseover / _mouseout instead of shape_*.
• addEasyprint() custom export sizes no longer need extra CSS. Pass them in easyprintOptions(sizeModes = ...) as R lists, for example list(scale = 3, name = "3x current view") (same zoom and labels, more pixels) or list(width = 3000, height = 1800, name = "High res"). CurrentSize still exports at the widget size (often low-res in Quarto/HTML). Custom width/height sizes keep the current map view by default (keepView = TRUE in the size-mode list). Set keepView = FALSE to keep the zoom level and export a larger area. See inst/examples/easyprint.R.
