Module @metreeca/wire-sparql-oxigraph - v0.12.0

Oxigraph in-memory WASM store connector for the @metreeca/wire storage connector collection.

Exposes an Oxigraph WASM store, running entirely in-process with no external server required, through the common Repository API.

Important

Transaction Isolation — None. Updates apply immediately to the in-memory store, with no execute bracketing.

Oxigraph JavaScript/WASM API

@metreeca/wire-sparql-oxigraph

SPARQL connector for @metreeca/wire backed by an Oxigraph in-memory WASM store.

Exposes an Oxigraph WASM store through the common @metreeca/wire-sparql Repository interface, running entirely in-process with no external server required.

Installation

npm install @metreeca/wire-sparql           # the SPARQL query API
npm install @metreeca/wire-sparql-oxigraph  # this connector
npm install oxigraph                        # peer dependency

Warning

TypeScript consumers must use "moduleResolution": "nodenext"/"node16"/"bundler" in tsconfig.json. The legacy "node" resolver is not supported.

Usage

Create an in-process Oxigraph store with createOxiRepository, then issue queries and updates through the @metreeca/wire-sparql Repository API:

import { createOxiRepository } from "@metreeca/wire-sparql-oxigraph";

const repository = createOxiRepository();

See @metreeca/wire-sparql for the Repository API: ask, select and construct query the store, update, merge and store write to it, and execute and close manage transactions and resources.

Important

This connector provides no transaction isolation: updates apply immediately to the in-memory store, with no execute bracketing.

Warning

Datasets apply to queries only: an update given a dataset listing any graphs is rejected and leaves the store as it was, since Oxigraph offers no way to run an update against an explicit dataset.
