Install

Install from npm

npm install nodemailer-trap-plugin --save

Usage

1. Load the trap function

var trap = require('nodemailer-trap-plugin').trap;

2. Attach it as a 'compile' handler for a nodemailer transport object

nodemailerTransport.use('compile', trap(options))

Where options

  • to - the email address used to send emails to. Default: ''
  • subject - the subject formatted. Default: '[DEBUG] - To: {0}, Subject: {1}'
  • passthrough - the regex / string / function to passthrough emails without modification (It works only for single recipient). Default: false.

Example

var nodemailer = require('nodemailer');
var trap = require('nodemailer-trap-plugin').trap;
var transporter = nodemailer.createTransport();

transporter.use('compile', trap({
  to: 'admin@example.org',
  passthrough: '@domain.com'
}));

// first email
transporter.sendMail({
  from: 'noreply@example.org',
  to: 'john.doe@example.com',
  subject: 'Hello John'
});

// second email
transporter.sendMail({
  from: 'noreply@example.org',
  to: 'jane@domain.com',
  subject: 'Hello Jane'
});

The first email has been sent to admin@example.org with subject "[DEBUG] - To: john.doe@example.com, Subject: john.doe@example.com"

The second email has been delivered to recipient without modifications because to field is satisfied options.passthrough

}));

var trap = require('nodemailer-trap-plugin').trap;

    return toAddress.indexOf('@domain.com') > -1;
  }
}));
