Features

• One package to get a working SPARQL client in javascript or React
• Powerful templating for queries via placeholder variables
• Client-level prefix management
• Automated results parsing
• Query validation out-of-the-box
• Fully customisable behaviour via "exchanges"

While SPARQL is an great language, client libraries today typically come with a limited set of features and offload the additional work to developers who are using them.
We aim to create a more powerful and developer-friendly out-of-the-box experience instead.

Installation

npm install @databorg/client

Basic usage

const result = await client.query({
  query: `SELECT ?p ?o WHERE { ?uri ?p ?label } LIMIT 5`,
