addFlags progress

Is there a way to get the progress of addFlags method? I tried listening on update event but it’s shows nothing.

EDIT: It also doesn’t delete all messages when dealing with large mailbox (229882 messages), is there a solutions for this?

const Imap = require('imap');

const imap = new Imap({
    user: '[e-mail]',
    password: 'xxxxxxxxx',
    host: 'imap.mail.yahoo.com',
    port: 993,
    tls: true
});

imap.connect();

imap.on('ready', () => {
    console.log('Client ready');
    imap.openBox('INBOX', false, (err, box) => {
        if (err) error(err);
        console.log(`INBOX open (${box.messages.total})`);
        imap.seq.addFlags('1:*', 'Deleted', err => {
            if (err) error(err);
            console.log('Flags added');
            imap.expunge('1:*', err => {
                if (err) error(err);
                console.log('Expunge done');
                imap.closeBox(false, err => {
                    if (err) error(err);
                    console.log('Box closed');
                    imap.end();
                    console.log('The end');
                });
            })
        });
    });
});

imap.on('update', (seqno, info) => {
    console.log('update ' + seqno);
})

function error(err) {
    console.log('Error: ' + err.message);
    process.exit(1);
}

For flag modifications, currently we enforce a silent option that prevents flag updates from the server. Initially this decision was made because of how the server sends these flag updates (it sends them as FETCH responses), which made things complicated. I’m not sure if that is the case with the codebase nowadays though.

For checking for a non-empty mailbox, there are a variety of different methods to choose from, including:

• Check mailbox.total (mailbox being the object passed to openBox() callbacks), it should update as needed, but I’m not sure offhand about after an expunge
• Do .status() on an unopened mailbox, the callback is given a similar mailbox object as with openBox()
• Doing something like imap.seq.fetch('1')
• If the server supports the ESEARCH extension, you can do imap.esearch(['ALL'], ['COUNT'], (err, info) => {})
• If the server supports the QUOTA extension, you could use imap.getQuotaRoot() and then imap.getQuota() to get usage information for a mailbox

You can just do a simple .search() for messages with the deleted flag set:

imap.search([ 'DELETED' ], (err, results) => {
  if (err) throw err;
  console.log(results.length + ' messages still marked for deletion');
});
