What it does
Add 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 vs remote URL), R2 via Git LFS by default, remote URLs by passthrough. Use when registering a new dataset in a scaffolded portal.
PortalJS, Add Dataset
Overview
Register a dataset in a PortalJS (portaljs-catalog) portal. The skill appends one entry to
datasets.json, the single source of truth for the catalog, and routes the underlying
bytes by source first, then size: a local file defaults to R2 via Git LFS, a remote URL
defaults to passthrough (no copy). No per-dataset page is created; the catalog at /search
lists the new entry and the dynamic showcase route pages/[owner]/[slug].tsx renders it
automatically at /@<namespace>/<slug>. Supported formats for the showcase preview: CSV,
TSV, JSON (array), and GeoJSON.
Prerequisites
- A scaffolded PortalJS portal (see
portaljs-new-portal) withdatasets.json,package.json, andpages/[owner]/[slug].tsxpresent. - The source data: a local file path or a publicly reachable URL.
- For the R2/Git LFS default route:
gitandgit-lfsinstalled, and an Arc account token (or an OSS Giftless key) to mint a push-scoped LFS credential. - Node 18+ and npm available in the portal directory.
