portaljs-add-resource
Add another file (resource) to an EXISTING dataset in a PortalJS portal — a data dictionary, methodology, or an additional data file. Turns a single-file dataset into a multi-resource one; the showcase renders a section per resource. Use when a dataset needs a second file, such as a data dictionary, methodology doc, or an additional period's data.
npx skills add datopian/portaljs --skill portaljs-add-resource --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# PortalJS — Add Resource ## Overview Add a resource — an additional file — to a dataset that already exists in a `portaljs-catalog` portal. Where `/portaljs-add-dataset` creates a **new** dataset (one file), this skill adds a file to an **existing** one: a data dictionary, a methodology document, or another data file (e.g. a second year's figures). Mirrors the Frictionless Data Package model: a dataset holds a `resources[]` array, and the showcase at `/@<namespace>/<slug>` renders one section per resource (preview, schema, download). A single-file dataset migrates to `resources[]` automatically the first time a second file is added — no data is lost. ## Prerequisites - An existing PortalJS portal (`portaljs-catalog` template) with `datasets.json`, `package.json`, and `pages/[owner]/[slug].tsx` present. - The target dataset already registered in `datasets.json`. - The new resource's source: a local file path or a public URL, in CSV, TSV, JSON (array), or GeoJSON format. - Node 18+ installed to run `npx next build` for verification. ## Instructions The canonical, full step-by-step workflow lives in [`.claude/commands/portaljs-add-resource.md`](https://github.com/datopian/portaljs/bl

What does the portaljs-add-resource skill do?
Add another file (resource) to an EXISTING dataset in a PortalJS portal — a data dictionary, methodology, or an additional data file. Turns a single-file dataset into a multi-resource one; the showcase renders a section per resource. Use when a dataset needs a second file, such as a data dictionary, methodology doc, or an additional period's data.
How do I install it?
Run `npx skills add datopian/portaljs --skill portaljs-add-resource --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From datopian/portaljs, a repository with 2,337 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
