What it does
Migrate a whole ArcGIS Hub site into a PortalJS Arc portal end-to-end. Harvests the Hub /data.json (DCAT-US) inventory, exports every FeatureService layer through the ArcGIS REST query API with resultOffset paging, converts each to the serverless dual tier (PMTiles render + GeoParquet query) with tabular items to Parquet, pushes everything to Cloudflare R2 via Git LFS, appends dual-tier datasets.json entries, and writes a source-vs-derived parity report. Use to move a City or sector ArcGIS Hub open-data portal onto PortalJS with no server-side compute.
ArcGIS Hub → PortalJS
Overview
Migrate an entire ArcGIS Hub open-data site into a PortalJS Arc portal in one pass.
Every Hub site is machine-readable, a DCAT-US catalog at /data.json, with every dataset
backed by an ArcGIS REST FeatureService, so migration is a harvest → export → convert →
publish → verify pipeline that runs almost fully automated on the operator's machine, no
server-side compute. The tooling is the reusable arcgis-to-portaljs migrator: input is one
Hub URL, output is a ready-to-deploy PortalJS catalog plus a parity report.
The skill is an orchestrator: it reuses the DCAT-US harvest from portaljs-migrate, the
ogr2ogr/tippecanoe/duckdb dual-tier conversion from portaljs-add-geo, and the bulk
Git-LFS → R2 push from portaljs-migrate. Its novel parts are the FeatureService REST export
loop (paged features, not just a link) and the source-vs-derived parity report.
Prerequisites
- A scaffolded PortalJS portal whose template ships
components/MapPreview.tsxandcomponents/GeoQuery.tsx(PR #1647 or later). Runportaljs-new-portalfirst if none. - Native CLIs: GDAL (
ogr2ogr,ogrinfo), tippecanoe, duckdb (withspatial), and jq. macOS:brew install gdal tippecanoe duckdb jq; Debian/Ubuntu:apt-get install gdal-bin duckdb jqplus tippecanoe (apt or build from source); Windows via WSL. The skill hard-stops with the install hint if any is missing. - Arc credentials for the Git-LFS → R2 push (the token
portaljs-deployresolves), or an OSS self-hosted Giftless.
