express-nodemailer

The small helper for Express that allows you to send email using nodemailer

The typescript support module for Express, that allow you to send an email using Nodemailer in the route handler by calling a certain method from the response object.

Install

# With npm 
npm install --save express-nodemailer
 
# With yarn 
yarn add express-nodemailer

Usage

Initialization

 
// Declare module
import expressNodemailer from "express-nodemailer"; 
 
// The parameters that are used as `options` argument for createTransport method of Nodemailer
const options = {
    host: 'smtp.example.com',
    port: 465,
    secure: true,
    auth: {
        user: 'user',
        pass: 'pass'
    }
};
 
// The parameters that are used as `defaults` argument for createTransport method of Nodemailer
const defaults = {
    from: "[e-mail]",
};
 
// Initialize a module to extends your Express application
expressNodemailer(app, options, defaults); // `app` is the Express application object
 
// Some Express source code before start server listening...

Initialization of expressNodemailer extends your Express application by mounting a special middleware to it which implements the ability to send en email by calling the sandMail method from the response object.

For direct use of the Nodemailer functionality, the transporter object itself, created with the given arguments, will be available in the Express application object:

app.expressNodemailer.transporter

Sending an email

Now in your route handler you can send an email by calling sendMail like this:

app.get('/', (req: Request, res: Response) => {
  res.sendMail(
      '[e-mail]',
      'subject',
      'path/to/text/template',
      'path/to/html/template'
  ).then((result) => { // On success
      console.info(result) // --> The `SentMessageInfo` object of nodemailer
  }).catch(err => { // On fail
      console.error(err) // --> some catched error during sending
  })
})

This method has four arguments:

sendMail: (to: string, subject: string, text: string, html?: string)

• to - REQUIRED - Comma separated list or an array of recipients email addresses
• subject - REQUIRED - The subject of the e-mail
• text - REQUIRED - The path to template file for text body of email
• html - The path to template file for html body of email

The last two arguments are the paths to the template files that are rendered by same render process as Express. For example, if your Express application use jade view engine, you should also write your email templates in jade.
