Send a PDF File with nodemailer via a html form - html

Question

I have a form in which has an upload file input. I want the user to be able to upload their file and send it via the form. At the moment the PDF file shows attached in the email but doesn't contain any data and won't open etc.
This is what I currently have within the nodemailer options:
let mailOptions = {
from: '"Macwear Clothing" <shop#macwearclothing.com>', // sender address
to: req.body.email, // list of receivers
subject: 'Order Review', // Subject line
text: 'Order Acception', // plain text body
html: output, // html body
attachments: [{'filename': 'needlesheet.pdf', 'content': req.body.needle, 'contentType': 'application/pdf'
}]
};
Client Side index.ejs file
<div class="fileUpload up<%= item.number %>" id="m<%= item.number %>">
<div class="fileUploadContent">
<h2>Customer:
<%= item.email %>
</h2>
<div class="uploadFile">
<input id="needle" type="file" name="needle" value="Upload File >">
</div>
<form method="POST" action="send" name="sendNeedleSheet" enctype="multipart/form-data">
<div class="optionalMessage">
<span>Optional Message:</span>
<textarea class="customTextArea" name="message"></textarea>
<input id="email" name="email" type="hidden" value="<%= item.email %>">
</div>
<div class="modalOptions">
<div class="mButton ok">
<button class="customButton" type="submit">Send</button>
</div>
<div class="mButton cancel">
<span>Cancel</span>
</div>
</div>
</form>
</div>
</div>

Answer 1

I simply used Multer to handle the uploading of the file. All that was required was to set the multer upload directory.
var upload = multer({dest: './public/uploads/'});
And then within the /send route add in upload.single('needle') and remove the arrow function:
app.post('/send', upload.single('needle'), function (req, res, next) {
});
Then within the attachments in mailOptions:
attachments: [
{
filename: req.file.originalname,
path: req.file.path
}
]
Lastly it is important to set the enctype on the HTML form to multipart/form-data otherwise the file upload via multer will not work.

Answer 2

you using path for both your attachment and static path so the document will not display its extension
try:
app.use(express.static('public'))
