Trying to use Haraka as the Mail Server in our new project

[shemeerfr]

Trying to use Haraka as the Mail Server in our new project ,We are trying to make our own plugin and no way we could find a solution to access the mail properties like Body and the attachments , Can any one please help us to find an existing plugin which we could get the mail properties like , Receivers, Body , Attachment etc.. Or the sample code snippet that can be used to access this properties

Below is a sample code which we are writing our plugin

var util=require('util');

exports.register = function () {
    this.logdebug("Initializing Parse Message Plugin ....");
    this.register_hook('attachment', 'process_attachments');
};

exports.hook_data = function (next, connection) {
    this.logdebug("inside hook_data ....");

    // Enable mail body parsing - should be enabled in hook_data
    connection.transaction.parse_body = true;

    next();
}

exports.hook_data_post = function (next, connection) {
    this.logdebug("inside hook_data_post ....");

    const transaction = connection.transaction;

    this.logdebug('length is ', transaction.body.children?.length);

    // Extract text and attachments from the email parts
    if (transaction.body.children?.length) {
        for (const part of transaction.body.children) {
            //this.logdebug('part is', util.inspect(part));
            if (part.ct === 'text/plain') {
                // This part is the plain text body
                this.loginfo('Body text:', part.bodytext);
            } else if (part.ct.includes('application/octet-stream')) {
                // This part is the attachment
                const attachment = {
                    filename: part.ct,
                    content: part.body_text_encoded, // or part.body, depending on how it's stored
                    contentType: part.ct
                };
                this.process_attachments(connection, [attachment]);
            }
        }
    }

    next();
}

exports.process_attachments = function (connection, attachments) {
    for (const attachment of attachments) {
        this.loginfo(`Received attachment: ${attachment.filename}, Size: ${attachment.content.length}`);
        // Process the attachment here
    }
}

exports.hook_queue = function (next, connection) {
    this.logdebug("inside hook_queue ....");

    // Enable mail body parsing - should be enabled in hook_data
    connection.transaction.parse_body = true;

    // get a decoded copy of a header, e.g. From
    var from_header = connection.transaction.header.get_decoded('From');
    this.loginfo('from is', from_header);
    
    // get a header that doesn't need to be decoded:
    var msg_id = connection.transaction.header.get('Message-ID');
    this.loginfo('msg_id is', msg_id);
    
    // get multiple headers, e.g. Received:
    var received = connection.transaction.rcpt_to;
    this.loginfo('received is', received);

    next();
}

exports.shutdown = function () {
    this.loginfo("Shutting Parse Message Plugin.");
};

have you figured out a way to do this properly?
I noticed that body parts may be 2 levels deep when dealing with attachments ...
