XMPP identifiers (JID) for JavaScript

JID type local @ domain / resource usage
domain wonderland.net servers and components

Install

npm install @xmpp/jid

Usage

var jid = require("@xmpp/jid");

/*
 * All return an instance of jid.JID
 */
var addr = jid("alice@wonderland.net/rabbithole");
var addr = jid("alice", "wonderland.net", "rabbithole");

addr instanceof jid.JID; // true

// domain JIDs are created passing the domain as the first argument
var addr = jid("wonderland.net");

/*
 * local
 */
addr.local = "alice";
addr.local; // alice
// same as
addr.setLocal("alice");
addr.getLocal(); // alice

/*
 * domain
 */
addr.domain = "wonderland.net";
addr.domain; // wonderland.net
// same as
addr.setDomain("wonderland.net");
addr.getDomain(); // wonderland.net

/*
 * resource
 */
addr.resource = "rabbithole";
addr.resource; // rabbithole
// same as
addr.setResource("rabbithole");
addr.getResource(); // rabbithole

addr.toString(); // alice@wonderland.net/rabbithole
addr.bare(); // returns a JID without resource

addr.equals(some_jid); // returns true if the two JIDs are equal, false otherwise
// same as
jid.equal(addr, some_jid);

Escaping

The XEP-0106 defines a method to escape and unescape characters that aren't allowed in the local part of the JID. This library fully implement it.

const addr = jid("contact@example.net", "xmpp.net");
addr.toString(); // contact\40example.net@xmpp.net
// for display purpose only
addr.toString(true); // contact@example.net@xmpp.net

For user input, use

jid("contact@example.net", "xmpp.net");
// over
jid("contact@example.net@xmpp.net");
