SASL

SASL Negotiation for @xmpp/client.

Included and enabled in @xmpp/client.

Usage

$3

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

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

$3

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

`js
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");
}
``
