Save ExpressJS view ejs render to a variable

Question

Save ExpressJS view ejs render to a variable

I'm trying to set up a confirmation email which is launched from Expressjs. This email template is in html (now ejs) and I need to pass variables to it so I can later save in a variable and send it with nodemailer.

Im trying to do something like this whitout success:

var final_html = res.render('confirm', {variables: 'aasdad'});

NodeMailer code:

var mailOptions = {
                      from: test@test.com, // sender address
                      to: 'test@test.com', // list of receivers
                      subject: 'Welcome '+req.body.name, // Subject line
                      html: final_html
                  };

How can achieve this?

Thanks in advance!

PD: Post answer code:

var final_html = res.render('confirm', {url: 'aasdad'}, function(err, html) {
                     if (err){ return err;}
                     return html;
                  });

node.js
express
ejs
nodemailer

Just pass in a callback as a third argument and it will get called with (err, final_html):

res.render('confirm', {variables: 'aasdad'}, function(err, final_html) {
  if (err) throw err; // TODO: handle errors better

  var mailOptions = {
    from: 'test@test.com', // sender address
    to: 'test@test.com', // list of receivers
    subject: 'Welcome ' + req.body.name, // Subject line
    html: final_html
  };

  // call node-mailer with `mailOptions` here ...
});
