@momsfriendlydevco/email

This module is a thin wrapper around the nodemailer module which loads its config from the locations specified in the Doop project.

Features:

• Object based syntax
• Out-of-the-box compatible with Doop projects and their configuration system
• Includes Nodemailer-Plugin-Inline-Base64 as default to correctly convert Base64 inline to CID attachments
• Template attachment and compiling using Handlebars

Quickstart guide

If you're project is already setup with appropriate config (see Expected Config) you should just be able to call the module as follows:

var email = require('@momsfriendlydevco/email');

email()
	.send({
		to: '[email protected]',
		from: '[email protected]',
		subject: 'Plain email test via mfdc-email',
		text: 'Hello World',
	}, function(err, res) {
		// Do something with the result
	});

or using chainable methods:

var email = require('@momsfriendlydevco/email');

email()
	.to('Joe Random <[email protected]>')
	.subject('HTML chainable method email test via mfdc-email')
	.html('<p>Hello <b>World</b></p>')
	.send(function(err, res) {
		// Do something with the result
	});

Debugging

This module uses the Debug NPM. Simply set the environment variable to DEBUG=email (or any valid enabling glob) to see the output.

> DEBUG=email mocha test/mailgun.js
  Mailgun > Send
  email Email
  email =======================================
  email To: [email protected]
  email Subject: Plain email test via mfdc-email
  email -----------------
  email Hello Joe
  email ------ End ------
  email  +0ms

Using template views

Specifying the template property either as a key in the send() object or via the chainable .template() method, will specify the file on disk to be used when composing the email.

• The type of email to send is determined by the file extension. .txt files are plain text and .html files are rich content.
• All templates are rendered via Mustache with the parameters used taken from the templateParams option.
• Mustache will automatically escape all variables. If you wish to use an unsecaped variable like a URL encase it in three levels of brackets rather than two e.g. {{{url}}}

var email = require('@momsfriendlydevco/email');

email()
	.to('Joe Random <[email protected]>')
	.subject('Password Recovery')
	.template(config.root + '/views/emails/password-recovery.txt')
	.templateParams({
		name: 'Joe Random',
		signoff: 'The MFDC team',
	})
	.send();

API

send(email, callback)

Dispatch an email. This is as functionally similar to the Nodemailer send() command as possible. Use this if lower level access is required. Returns a promise.

to, from, cc, bcc, subject, text, html()

All these methods are chainable:

var email = require('@momsfriendlydevco/email');

email()
	.to('[email protected]')
	.subject('something')
	.send();

attachments()

Attachments are an array of various inputs including inline file contents, paths to files or streams.

var email = require('@momsfriendlydevco/email');

email()
	.to('[email protected]')
	.subject('something')
	.attachments([
		{filename: 'inline-file.txt', content: 'Hello World!'},
		{filename: 'file-on-disk.txt', path: '/tmp/file-on-disk.txt'},
		{filename: 'file-from-stream.txt', fs.createReadSteram('/tmp/file-stream.txt')},
		{raw: '... mime encoding ...'},
	])
	.send();

See the NodeMailer attachment specification for more details.

params, templateparams

Populate the Handlebars replacement engine with a given object.

template

Specify a template file to read to obtain the email body. The file extension should be .txt or .html to determine the body type. Specify .params (or .templateParams) to populate the Handlebars replacement engine.

var email = require('@momsfriendlydevco/email');

email()
	.to('[email protected]')
	.subject('something')
	.template('/a/file/somewhere.txt')
	.params({username: 'joe'})
	.send();

init()

Reinitialize the mail transport and reset all defaults to the global values.
