What it does

Arcgis To Portaljs is an agent skill from datopian/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.

Context cost

Arcgis To Portaljs loads about 2k tokens when it runs, and up to ~7.1k if it reads all its reference files. Until then it costs about 144 tokens; SKILL.md has 739 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~144
When it runs · the whole SKILL.md, loaded when a task matches: ~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~7.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.tsx and components/GeoQuery.tsx (PR #1647 or later). Run portaljs-new-portal first if none.
Native CLIs: GDAL (ogr2ogr, ogrinfo), tippecanoe, duckdb (with spatial), and jq. macOS: brew install gdal tippecanoe duckdb jq; Debian/Ubuntu: apt-get install gdal-bin duckdb jq plus 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-deploy resolves), or an OSS self-hosted Giftless.

Instructions

The canonical, full step-by-step workflow is .claude/commands/arcgis-to-portaljs.md — the single source of truth. Read and follow it when executing. Summary:

Gather input — Hub URL, portal directory, project slug, optional flags (--limit, --only, --dry-run, --namespace-mode). Interview if missing; never dead-end.
Check native tools (ogr2ogr, tippecanoe, duckdb + spatial, jq). Any missing → print the per-OS install and stop.
Validate the portal directory and confirm the geo showcase components exist.
Harvest the Hub /data.json (reuse the portaljs-migrate DCAT-US map) and classify each item: vector (FeatureService), table, or non-data (web map / 3D / imagery → skipped). Under --namespace-mode owner, resolve namespaces through a publisher-normalization table with title-prefix fallback for broken {{source}} publishers (multi-publisher Hubs ship dirty publisher labels). Dedup near-duplicate hosted-view layers — but only after a mandatory live record-count check on BOTH twins: equal ⇒ dedup (keep the source layer, log the pair); different ⇒ keep both as distinct datasets. Consolidate per-year dataset series into one year-partitioned Parquet with legacy per-year view entries. Enrich from the AGOL item: sanitized metadata (license/description/dates), cleaned display title (cleanTitle — raw title still drives the slug), category (item categories → meaningful theme → keyword mapping), and a thumbnail snapshot into public/thumbnails/.
Export each vector layer through the ArcGIS REST query API with resultOffset paging (f=geojson, outSR=4326); fall back to keyset paging on transfer limits; accept a customer File Geodatabase dump for very large layers.
Convert each layer to the dual tier via the portaljs-add-geo recipe (PMTiles + GeoParquet); tabular items to Parquet. Preserve the native-CRS original.
Publish — bulk Git-LFS track + one push to R2 through Giftless, then append dual-tier datasets.json entries (upsert on (namespace, slug)).
Write arcgis-parity-report.md — record count, extent, attribute schema, and geometry validity, source vs derived, per dataset, plus the migrated/skipped/failed accounting.
Report the inventory, migrated datasets, R2 push, and parity summary.

Show full SKILL.md (234 more words)Show less

Output

Created: data/<namespace>/<slug>.pmtiles, .parquet, and the original per vector dataset (all LFS-tracked → R2); Parquet + original per table; arcgis-parity-report.md.
Modified: datasets.json (one dual-tier entry per vector dataset, one resource entry per table); .gitattributes (LFS tracking).
Verified: the parity report compares each derived artifact to the live FeatureService.
Result: /@<namespace>/<slug> renders <MapPreview> + <GeoQuery> for each vector dataset with no page edits; the catalog lists everything migrated.

Error Handling

Symptom	Cause	Fix
`MISSING_INPUT`	No Hub URL provided	Pass the site root (e.g. `https://hub-lewisville.opendata.arcgis.com`) and retry.
`MISSING_TOOLS`	`ogr2ogr`/`tippecanoe`/`duckdb`/`jq` (or duckdb `spatial`) absent	Print the per-OS install line and stop; re-run after installing.
`NOT_A_PORTAL`	Target dir has no `datasets.json` / geo components	Run `portaljs-new-portal` first, then re-run.
`HARVEST_FAILED`	`/data.json` unreachable or not DCAT-US	Confirm the site is an ArcGIS Hub and the feed loads in a browser.
`EXPORT_FAILED`	One FeatureService layer errored or hit a hard transfer cap	Logged and skipped; try keyset paging or a customer FGDB dump for that layer.
`LFS_PUSH_FAILED`	Missing/expired Arc token or unset `lfs.url`	Re-mint the JWT (see `portaljs-deploy`); confirm `git config lfs.url`.

Examples

Example 1 — Migrate a City Hub (Lewisville)
