javascript-wasm SKILL.md skillB
javascript-wasm from sparq-org/sparq is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use the sparq RDF+SPARQL engine from JavaScript/TypeScript (Node >=18 or the browser) via its WebAssembly build and the @sparq-org/sparq RDF-JS wrapper — load Turtle/N-Triples/N-Quads/TriG, run SPARQL 1.1 SELECT/ASK, stream large results, count without materialising, apply SPARQL Update / quad deltas, do RDF-JS match()/countQuads(), and ingest gzip/zstd-compressed RDF. Reach for this when wiring sparq into a Node service, browser tab, or RDF-JS pipeline.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# sparq from JavaScript / WebAssembly
sparq is a Rust RDF triplestore + SPARQL engine compiled to WebAssembly. The npm package **`@sparq-org/sparq`** wraps it in an idiomatic [RDF/JS](https://rdf.js.org/) surface (`SparqStore`, Map-like `Bindings`, spec terms via `@rdfjs/types`); it runs unchanged in Node >= 18 and the browser. There is also a thin raw wasm class (`Store`) if you want SPARQL-JSON strings with no JS-side term materialisation. The bundle size is tracked live on the [benchmarks dashboard](https://sparq.jeswr.org/dev/bench) under the Core metrics (`wasm_bundle_bytes`).
Use `SparqStore` (the high-level wrapper) by default — it covers SELECT/ASK (`query`/`queryBindings`/`queryBoolean`) and CONSTRUCT/DESCRIBE (`queryQuads`, returning RDF/JS `Quad`s). Drop to the raw `Store` only to skip term materialisation entirely (SPARQL-JSON / N-Triples strings) or for query-plan introspection.
## Quickstart
```js
import { SparqStore, DataFactory as DF } from '@sparq-org/sparq';
// init() runs lazily on first construction.
const store = await SparqStore.fromString(`
@prefix ex: <http://ex/> .
ex:alice ex:name "Alice" ; ex:knows ex:bob .
ex:bob ex:name "Bob"@en .

How to install
mdr add sparq-org/sparq/javascript-wasm@sha256:d43935b878de8ca8The line at the top of this page pins the label git:20261029.e03a911, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
