Package Exports

@sib-swiss/sparql-editor
@sib-swiss/sparql-editor/dist/sparql-editor.js
@sib-swiss/sparql-editor/dist/sparql-editor.min.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@sib-swiss/sparql-editor) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

💫 SPARQL editor web component

A standard web component to easily deploy a user-friendly SPARQL query editor for a specific SPARQL endpoint, based on the popular YASGUI editor with advanced autocomplete for predicates based on classes.

The editor retrieves metadata about the endpoint by directly querying the SPARQL endpoint, so all you need to do is to properly document your endpoint. Reducing the need for complex infrastructure, while making your SPARQL endpoints easier to query for users and machines.

Prefixes are automatically pulled from the endpoint using their definition defined with the SHACL ontology (sh:prefix/sh:namespace).
Example SPARQL queries defined using the SHACL ontology are automatically pulled from the endpoint (queries are defined with sh:select|sh:ask|sh:construct|sh:describe, and their human readable description with rdfs:comment). Checkout the sparql-examples project for more details.
Autocomplete possibilities for properties and classes are automatically pulled from the endpoint based on VoID description present in the triplestore (void:linkPredicate|void:property and void:class). The proposed properties are filtered based on the predicates available for the class of the subject related to where your cursor is 🤯. Checkout the void-generator project to automatically generate VoID description for your endpoint.

🚀 Use

Import from CDN

<script type="module" src="https://unpkg.com/@sib-swiss/sparql-editor"></script>

Or install with a package manager in your project:

npm install --save @sib-swiss/sparql-editor
# or
pnpm add @sib-swiss/sparql-editor

Use the custom element in your HTML/JSX/TSX code:

<sparql-editor endpoint="https://sparql.uniprot.org/sparql/"></sparql-editor>

You can customize the number of examples displayed on the main page, buttons color, and provide other HTML elements to be included under the SPARQL examples (e.g. about and links to relevant resources):

<sparql-editor
  endpoint="https://www.bgee.org/sparql/"
  examples-on-main-page="10"
  style="--btn-color: white; --btn-bg-color: #00709b;"
>
  <h1>About</h1>
  <p>This SPARQL endpoint contains...</p>
</sparql-editor>

[!WARNING]

Metadata are retrieved by a few lightweight queries sent from client-side JavaScript when the editor is initialized, so your SPARQL endpoint should accept CORS (either from *, which is recommended, or just from the URL where the editor is deployed)

📝 Basic example

No need for a complex project you can integrate SPARQL editor in any HTML page by importing from a CDN.

Create a index.html file with:

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <title>SPARQL editor dev</title>
    <meta name="description" content="SPARQL editor demo page" />
    <link rel="icon" type="image/png" href="https://upload.wikimedia.org/wikipedia/commons/f/f3/Rdf_logo.svg" />
    <!-- Import the module from a CDN -->
    <script type="module" src="https://unpkg.com/@sib-swiss/sparql-editor@0.1.3"></script>
  </head>

  <body>
    <div>
      <sparql-editor
        endpoint="https://www.bgee.org/sparql/"
        examples-on-main-page="10"
        style="--btn-color: white; --btn-bg-color: #00709b;"
      >
        <h1>About</h1>
        <p>This SPARQL endpoint contains...</p>
      </sparql-editor>
    </div>
  </body>
</html>

Then just open this HTML page in your favorite browser.

You can also start a basic web server with NodeJS or Python (recommended):

npx http-server
# or
python -m http.server
