Jsreport with nodemailer-express-handlebars

Tan Tran

I use jsreport with nodemailer and nodemailer-express-handlebars to create html email. However in the afterRender script, the script could not access template.handlebar when configuring, it always yield an error: Error: EISDIR: illegal operation on a directory, read. Do anyone how can I access file from script?
Thanks in advance

I have also tried fs to read the file, but got the same error???

The error says you are trying to read the directory where the file is expected.
Please share your code in the afterRender.

I tried the example here "https://writejavascript.com/blog/sending-emails-with-node/". I set up the structure of directory as shown in the code and it can access the directory but always yield error: Error: EISDIR: illegal operation on a directory, read. The code as shown below:

function afterRender(req, res, done) {
    console.log('After rendered report.....................');
    console.log(req.data);
    
    var mailer = require("nodemailer");

    var hbs = require("nodemailer-express-handlebars");



    var smtpTransport = mailer.createTransport({
        host : "mail.xxx.no",
        port : 465,
        secure: true,
        auth : {
            user : "noreply@xxx.no",
            pass : "xxx"
        },
        tls : {
            rejectUnauthorized: false
        }

    });

    var options = {
        viewEngine : {
            extname: ".hbs",
            partialsDir: './data/etakeaway/Invoice/views',
            layoutsDir: './data/etakeaway/Invoice/views/layouts'
        },
        viewPath : './data/etakeaway/Invoice/views',
        extName: ".hbs"

    };

    smtpTransport.use('compile', hbs(options));

    var mail = {
        from: "XXX <noreply@xxx.no>",
        to: req.data.email,
        subject: "Receipt for order id " + req.data.orderId,
        text: "See the attached report",
        template: 'template',
        context: {
            name : 'Name',
            orderId : '#123456'
        },
        attachments: [
        {  
            filename: 'Receipt.pdf',
            content: new Buffer(res.content)
        }],
    }

    smtpTransport.sendMail(mail, function(error, response){
        smtpTransport.close();
        if(error){
            return done(error);
        }

        return done();
    });
}

I think that the error is not that of trying to read directory instead for a file. I have also tried fs to read file to test but still get the same error, despite the fact that the path is correct. Do you have an example of reading a file from script? Thanks in advance.

Did you check this tutorial?
https://jsreport.net/learn/periodical-report-sending-through-email

I think you over-complicate it with the extra handlebars when jsreport has it wired already and you can just email the outputs from the afterRender script.

Hi jan_blaha,
Actually I need to send an HTML email with some parameters and attachments, I used the example and it worked perfectly. But I need a more complex HTML email, so that I need someway to read the external file from the script. Currently, I solved the problem with built-in html feature of nodemailer, but it is not a good practice. Do you know how to read file from script? Thanks in advance

jan_blaha

Here is the code to read a file in the script and put it to the report result.

const fs = require('fs')
const path = require('path')
function afterRender(req, res) {
    res.content = fs.readFileSync(path.join(__appDirectory, 'myfile.txt'))
}

Still get the same error, maybe the issue comes from jsreport itself, or configuration???

Please try to create a minimal github repo and replicate the problem there so I can take a look.
