XDI-js is an XDI client library for JavaScript, intended to be used by browser-based applications to communicate with XDI servers.

A sample deployment of XDI-js is available at http://xdi-js.projectdanube.org.

Usage

Parser

var statement = xdi.parser.parseStatement('=markus<+email>&/&/"Markus"');
for (var i in statement.subject().subsegments()) alert(statement.subject().subsegments()[i]);

Graph

var graph = xdi.graph();
graph.root().context("=markus", true).context("<+email>", true).context("&", true).literal("markus.sabadello@gmail.com");
graph.root().context("=markus", true).relation("+friend", "=joe", true);
graph.root().context("=markus", true).relation("+friend", "=drummond", true);
graph.root().context("=markus", true).context("<+first>", true).context("<+name>", true).context("&", true).literal("Markus");
graph.statement("=markus<+last><+name>&/&/\"Sabadello\"");
graph.statement("=x/+y/(=a/+b/=c)");

Serialization and Deserialization

var graph = xdi.io.read(string);
alert(xdi.io.write(graph));

Client

var message = xdi.message("$anon");
message.toAddress("([@]!:uuid:8888)");
message.linkContract("$public$do");
message.operation("$get", "[@]!:uuid:8888<+name>");

message.send(
	"http://xdi.csp.org/myxdiendpoint",
	function(response) {
		alert(xdi.io.write(response));
	},
	function(errorText) {
		alert(errorText);
	}
);

Discovery

xdi.discovery(
	"@acmebread",
	function(discovery) {
		alert(discovery.cloudNumber());
		alert(discovery.xdiEndpoint());
	},
	function(errorText) {
		alert(errorText);
	}
);
