# Express Handlebars plugin for Nodemailer
This plugin works with nodemailer 6.x. And uses the [express-handlebars](https://github.com/express-handlebars/express-handlebars) view
engine to generate html emails.

# Install from npm
```bash
npm install nodemailer-express-handlebars
```
# Usage
```javascript
//reference the plugin
const hbs = require('nodemailer-express-handlebars');
//attach the plugin to the nodemailer transporter
transporter.use('compile', hbs(options));
//send mail with options
const mail = {
   from: 'from@domain.com',
   to: 'to@domain.com',
   subject: 'Test',
   template: 'email',
   context: {
       name: 'Name'
   }
}
transporter.sendMail(mail);
```

You can send a multipart html and text email by setting the `text_template` option on a mail message.
```javascript
const mail = {
   from: 'from@domain.com',
   to: 'to@domain.com',
   subject: 'Test',
   template: 'email',
   text_template: 'text',
   context: {
       name: 'Name'
   }
}
```
