Sails-hook-email-multi-transport NPM

sails-hook-email-multi-transport

Email hook for Sails JS, using Nodemailer, which allows for multiple Nodemailer transports for sending different types of email though different ways.

Note: This requires Sails v0.10.6+.

Installation

npm install sails-hook-email-multi-transport

Usage

sails.hooks.email.send(template, data, options, cb)

Parameter	Type	Details
template	((string))	Relative path from `templateDir` (see "Configuration" below) to a folder containing email templates.
data	((object))	Data to use to replace template tokens
options	((object))	Email sending options (see Nodemailer docs)
cb	((function))	Callback to be run after the email sends (or if an error occurs).

Configuration

By default, configuration lives in sails.config.email. The configuration key (email) can be changed by setting sails.config.hooks['sails-hook-email-multi-transport'].configKey. The configuration is a single configuration object or an array of objects that look like this:

Parameter	Type	Details
transporters	((array))	An array of `transporter` objects (described below)
templateDir	((string))	Path to view templates relative to `sails.config.appPath` (defaults to `views/emailTemplates`)
from	((string))	Default `from` email address
alwaysSendTo	((string))	If set, all emails will be sent to this address regardless of the `to` option specified. Good for testing live emails without worrying about accidentally spamming people.
testMode	((boolean))	Flag indicating whether the hook is in "test mode" globally for all transports. In test mode, email options and contents are written to a `.tmp/email-TRANSPORT.txt` file instead of being actually sent. Defaults to `true`.
defaultTransporter	((string))	The name of the transporter to use if none is specified.
useDefaultTransportIfMissing	((boolean))	Whether to fall back to the default transport if the specified name does not exist. Note that this generates a warning on the console.

Additionally, if the transporters configuration option does not exist, a new "default" transporter is created by reading the transporter options listed below directly from the config object. This allows backwards compatibility with sails-hook-email.

Transporter Object definition

Parameter	Type	Details
name	((string))	The name of this transporter to reference it later
service	((string))	A "well-known service" that Nodemailer knows how to communicate with (see this list of services)
auth	((object))	Authentication object as `{user:"...", pass:"..."}`
transporter	((object))	Custom transporter passed directly to nodemailer.createTransport (overrides service/auth) (see Other Transports)
testMode	((boolean))	Flag indicating whether the hook is in "test mode". In test mode, email options and contents are written to a `.tmp/email-TRANSPORT.txt` file instead of being actually sent. Defaults to `undefined` which inhertis from the global `testMode` setting described above.

Example Configuration

// [your-sails-app]/config/email.js
module.exports.email = {
  transporters: [
    {
      name: 'MyGmail',
      isDefault: true,
      service: 'Gmail',
      auth: {user: 'foobar@gmail.com', pass: 'emailpassword'},
      testMode: true
    }
  ]
};

Templates

Templates are generated using your configured Sails View Engine, allowing for multiple template engines and layouts. If Sails Views are disabled, will fallback to EJS templates. To define a new email template, create a new folder with the template name inside your templateDir directory, and add an html.ejs file inside the folder (substituting .ejs for your template engine). You may also add an optional text.ejs file; if none is provided, Nodemailer will attempt to create a text version of the email based on the html version.

Example of templates

Given the following html.ejs file contained in the folder views/emailTemplates/testEmail:

<p>Dear <%=recipientName%>,</p>
<br/>
<p><em>Thank you</em> for being a friend.</p>
<p>Love,<br/><%=senderName%></p>

executing the following command (after configuring for your email service and turning off test mode) :

sails.hooks.email.send(
  "testEmail",
  {
    recipientName: "Joe",
    senderName: "Sue"
  },
  {
    to: "joe@example.com",
    subject: "Hi there",
    transport: "MyGmail"
  },
  function(err) {console.log(err || "It worked!");}
)

will result in the following email being sent to joe@example.com
