Proxy for a SPARQL endpoint which logs all SPARQL requests and provides the last 20 requests as JSON. It works as backend for the SparqlViz tool.

Install all dependencies

npm install

Then you can start the proxy redirecting to a SPARQL endpoint (default http://localhost:8890) via

node server.js [--endpoint=http://localhost:8890]

There is an interface on port 5050 redirecting to a SPARQL endpoint.

On localhost:5060 you get the log of the last 20 SPARQL queries. New queries are also pushed as socket.io after connecting to this URL.
