How to attach file to an email with nodemailer

I have code that send email with nodemailer in nodejs but I want to attach file to an email but I can't find way to do that I search on net but I could't find something useful.Is there any way that I can attach files to with that or any resource that can help me to attach file with nodemailer?

var nodemailer = require('nodemailer');
var events = require('events');
var check =1;
var events = new events.EventEmitter();
var smtpTransport = nodemailer.createTransport("SMTP",{
    service: "gmail",
    auth: {
        user: "[email protected]",
        pass: "pass"
    }
});
function inputmail(){
    ///////Email
    const from = 'example<[email protected]>';
    const to  = '[email protected]';
    const subject  = 'example';
    const text = 'example email';
    const html = '<b>example email</b>';
    var mailOption = {
        from: from,
        to:  to,
        subject: subject,
        text: text,
        html: html
    }
    return mailOption;
}
function send(){
        smtpTransport.sendMail(inputmail(),function(err,success){
        if(err){
            events.emit('error', err);
        }
        if(success){
            events.emit('success', success);
        }
    });
}
///////////////////////////////////
send();
events.on("error", function(err){
    console.log("Mail not send");
    if(check<10)
        send();
    check++;
});
events.on("success", function(success){
    console.log("Mail send");
});

Include in the var mailOption the key attachments, as follow:

var mailOptions = {
...
attachments: [
    {   // utf-8 string as an attachment
        filename: 'text1.txt',
        content: 'hello world!'
    },
    {   // binary buffer as an attachment
        filename: 'text2.txt',
        content: new Buffer('hello world!','utf-8')
    },
    {   // file on disk as an attachment
        filename: 'text3.txt',
        path: '/path/to/file.txt' // stream this file
    },
    {   // filename and content type is derived from path
        path: '/path/to/file.txt'
    },
    {   // stream as an attachment
        filename: 'text4.txt',
        content: fs.createReadStream('file.txt')
    },
    {   // define custom content type for the attachment
        filename: 'text.bin',
        content: 'hello world!',
        contentType: 'text/plain'
    },
    {   // use URL as an attachment
        filename: 'license.txt',
        path: 'https://raw.github.com/andris9/Nodemailer/master/LICENSE'
    },
    {   // encoded string as an attachment
        filename: 'text1.txt',
        content: 'aGVsbG8gd29ybGQh',
        encoding: 'base64'
    },
    {   // data uri as an attachment
        path: 'data:text/plain;base64,aGVsbG8gd29ybGQ='
    }
 ]}

Choose the option that adjust to your needs.

Just look at here. Nodemailer > Message configuration > Attachments

The code snippet is below (pdfkit gets the stream):

// in async func
pdf.end();
const stream = pdf;
const attachments = [{ filename: 'fromFile.pdf', path: './output.pdf', 
contentType: 'application/pdf' }, { filename: 'fromStream.pdf', content: stream, contentType: 'application/pdf' }];
await sendMail('"Sender" <[email protected]>', '[email protected]', 'Test Send Files', '<h1>Hello</h1>', attachments);

Stream uses content not streamSource This bothered me before, share with everyone :)

Your code is almost right, just need to add, "attachments" property for attaching the files in your mail,

YOUR mailOption:

var mailOption = {
        from: from,
        to:  to,
        subject: subject,
        text: text,
        html: html
}

Just add attachments like

var mailOption = {
        from: from,
        to:  to,
        subject: subject,
        text: text,
        html: html,
        attachments: [{
            filename: change with filename,
            path: change with file path
        }]
}

attachments also provide some other way to attach file for more information check nodemailer community's documentation HERE

If you are passing options object in mail composer constructor and attachment is on http server then it should look like:

const options = {
    attachments = [
      { // use URL as an attachment
        filename: 'xxx.jpg',
        path: 'http:something.com/xxx.jpg'
      }
    ]
}

var mailer = require('nodemailer');
mailer.SMTP = {
    host: 'host.com', 
    port:587,
    use_authentication: true, 
    user: '[email protected]', 
    pass: 'xxxxxx'
};

Then read a file and send an email :

fs.readFile("./attachment.txt", function (err, data) {

    mailer.send_mail({       
        sender: '[email protected]',
        to: '[email protected]',
        subject: 'Attachment!',
        body: 'mail content...',
        attachments: [{'filename': 'attachment.txt', 'content': data}]
    }), function(err, success) {
        if (err) {
            // Handle error
        }

    }
});

The alternative solution is to host your images online using a CDN and link to the online image source in your HTML, eg. <img src="list_image_url_here">.

(I had problems with nodemailer's image embedding using nodemailer version 2.6.0, which is why I figured out this workaround.)

An added benefit of this solution is that you're sending no attachments to nodemailer, so the sending process is more streamlined.
