SASL

SASL Negotiation for @xmpp/client.

Included and enabled in @xmpp/client.

Usage

object

import { xmpp } from "@xmpp/client";

const client = xmpp({
  credentials: {
    username: "foo",
    password: "bar",
  },
});

function

Instead, you can provide a function that will be called every time authentication occurs (every (re)connect).

Uses cases:

• Have the user enter the password every time
• Do not ask for password before connection is made
• Debug authentication
• Using a SASL mechanism with specific requirements
• Fetch credentials from a secure database

import { xmpp } from "@xmpp/client";

const client = xmpp({ credentials: onAuthenticate });

async function onAuthenticate(authenticate, mechanisms) {
  console.debug("authenticate", mechanisms);
  const credentials = {
    username: await prompt("enter username"),
    password: await prompt("enter password"),
  };
  console.debug("authenticating");
  await authenticate(credentials, mechanisms[0]);
  console.debug("authenticated");
}
