esbuild-plugin-sparql

esbuild plugin to compile SPARQL .rq (query) and .ru (update) files with sparqlc during bundling.

• Transforms .rq/.ru into ESM modules
• Optional ?base= query to resolve relative IRIs

Install

npm i -D esbuild-plugin-sparql sparqlc esbuild

Usage

import esbuild from 'esbuild'
import sparql from 'esbuild-plugin-sparql'

await esbuild.build({
  entryPoints: ['src/index.ts'],
  bundle: true,
  outfile: 'dist/index.js',
  plugins: [sparql],
})

Import queries normally:

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

Or pass a base IRI to resolve relative IRIs:

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

Notes:

• The plugin handles both .rq and .ru.
• For Node.js runtime without bundling and support for import attributes (with: { base }), use node-loader-sparql.
