arcgis-to-portaljs
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
