What it does
Render a GeoJSON dataset on an interactive Leaflet map in the Views section of a dataset's showcase. Installs react-leaflet and a Map component, then renders the map for the chosen dataset. Use when a dataset's data is geographic and a map view is needed alongside the showcase's default metadata and download.
PortalJS, Add Map
Overview
Add an interactive Leaflet map as a view on a dataset's showcase in a
portaljs-catalog portal. The skill installs react-leaflet/leaflet (added directly, never @portaljs/components), writes a reusable Map component split across
MapView.tsx (the Leaflet code) and Map.tsx (a dynamic(..., { ssr: false }) wrapper,
since Leaflet touches window at module load), and renders <Map /> into the Views
section of the showcase route pages/[owner]/[slug].tsx for one chosen GeoJSON dataset.
The dataset should already carry format: "geojson" in datasets.json; if it doesn't
exist yet, the skill can copy the file and register it first.
Prerequisites
- A scaffolded PortalJS portal (see
portaljs-new-portal). - The target dataset registered in
datasets.jsonwithformat: "geojson"(seeportaljs-add-dataset), or a GeoJSON source file/URL to register. - Node 18+ and npm available in the portal directory.
