Very simple Node.js POST form inquiries - node.js

Question

I have a simple node.js app using express static and nodemailer with a POST form that emails the filled fields to myself. My problems are very simple, I'm just quite new to Node so I can't find a way to do them.
My first problem is that I can't find a way to put all the form data into the email's text. Below, I am trying to store my form data in a JSON and call it in the email text, but it doesn't work. It has only correctly worked for me when I only used one variable (ex. just req.body.name) for the text. How can I format my data together in the email?
My second problem is that I can find a way to handle the app after the email is sent. I want it to redirect to a success page, as shown in the marked line, but it does not work. Instead, the page goes to /reqform and displays an error message saying success.html doesn't exist (it is in the same public folder as my html file). I believe the problem lies in my sendFile usage, but I'm not sure.
app.post('/reqform', urlencodedParser, function (req, res) {
response = {
name: req.body.name,
email: req.body.email,
phone: req.body.phone
};
var mailContent = {
from: 'myemail#gmail.com',
to: 'myemail#gmail.com',
subject: 'Service Request From req.body.name',
text: response //*** Problem #1
};
transporter.sendMail(mailClient, function (error, info) {
if (error) {
console.log(error);
} else {
res.sendFile("success.html"); //** Problem #2
}
});
})
Any help is greatly appreciated. Thanks!

Answer 1

The default string value for a JavaScript Object is just "[object Object]". If you want anything else, you'll have to be specific with how you want it represented.
For example, JSON is a text/string format that represents values like Objects. It's separate from the Object itself, so you'll need to convert to use it:
var mailContent = {
// ...
text: JSON.stringify(response)
}
Or, provide your own formatting:
var mailContent = {
// ...
text: `Name: ${response.name}\nEmail: ${response.email}\nPhone: ${response.phone}`
}
It might be better to use res.redirect() in this case, allowing the client/browser to request success.html via your application's static() middleware:
res.redirect('/success.html');
res.sendFile() doesn't collaborate with any static() middleware to know about your public folder. It expects you to provide a full path either directly or with its root option:
res.sendFile(path.join(__dirname, 'public/success.html'));
