vite-plugin-sparql

Vite plugin that compiles SPARQL .rq (query) and .ru (update) files with sparqlc, so you can import them like regular modules.

• Transforms .rq/.ru to ESM at build/dev time
• Optional ?base= query to resolve relative IRIs
• Works in dev server and build

Install

npm i -D vite-plugin-sparql sparqlc

Usage

vite.config.ts:

import { defineConfig } from 'vite'
import sparql from 'vite-plugin-sparql'

export default defineConfig({
  plugins: [sparql()],
})

Import a query and execute it with sparql-http-client:

import env from '@zazuko/env'
import type { ParsingClient } from 'sparql-http-client'

const { default: selectAll } = await import('./queries/select-all.rq')

declare const client: ParsingClient
const rows = await selectAll({ env, client })

Pass a base IRI via query parameter to resolve relative IRIs in the file:

const { default: q } = await import('./queries/select-relative.rq?base=http%3A%2F%2Fexample.org%2F')

Notes:

• The plugin recognizes both .rq and .ru extensions.
• For runtime import attributes in Node.js (with: { base }), use the companion loader node-loader-sparql instead.
