portaljs-add-chartAdd a chart (line, bar, area, pie, or scatter) to a dataset's showcase in a PortalJS portal. Installs recharts, writes a reusable Chart component, and renders it in the showcase Views section. Use whe
portaljs-add-dcatMake a PortalJS portal harvestable by national/EU/US open-data portals — emit standards-compliant DCAT catalog feeds (DCAT 2/3, DCAT-AP, DCAT-US, national profiles) in JSON-LD, Turtle, and RDF/XML at
portaljs-add-datasetAdd a dataset (CSV, TSV, JSON, or GeoJSON) to an existing PortalJS portal. Appends an entry to datasets.json so the catalog and showcase render it automatically; routes the data by source (local file

Auto-ingest a geospatial file (GeoJSON, Shapefile, GeoPackage, KML/KMZ, FlatGeobuf, CSV-with-geometry) into a PortalJS portal on the user's own machine, with no server. Normalizes CRS to EPSG:4326, derives a PMTiles render tier and a GeoParquet query tier, pushes all three artifacts to Cloudflare R2 via Git LFS, and appends one dual-tier datasets.json entry the showcase auto-renders. Use when the source is a vector geo format that needs a map or spatial-query view.

Symptom	Cause	Fix
`MISSING_TOOLS`	`ogr2ogr`/`tippecanoe`/`duckdb` (or duckdb `spatial`) absent	Print the per-OS install line and stop; re-run after installing.
`UNSUPPORTED_FORMAT`	Raster `.tif`/`.tiff` (COG tier, later phase)	Use `portaljs-add-dataset` for tabular; await the COG phase.
`SHAPEFILE_NOT_ZIPPED`	Bare `.shp` with no siblings	Zip the whole `.shp/.dbf/.shx/.prj` set and pass the `.zip`.
`MULTI_LAYER`	GPKG/KML with more than one layer	List layers and ask which to ingest; pass the layer name.
`REPROJECTION_FAILED`	`ogr2ogr` error, often a missing `.prj`	Show stderr; re-run with `-s_srs EPSG:<code>`.
`EMPTY_OUTPUT`	Normalized GeoJSON has 0 features	Check the geometry column / CRS of the source.
`TILING_FAILED` / `GEOPARQUET_FAILED`	tippecanoe or duckdb non-zero	Show stderr; for very large inputs see the size escape hatch.
`LFS_PUSH_FAILED`	Missing/expired Arc token or unset `lfs.url`	Re-mint the JWT (see `portaljs-deploy`); confirm `git config lfs.url`.
