bedrock-mail
A Bedrock module that allows you to send automated, template-based emails in response to events. Data used in the templates comes from both data in the events and from "triggers" that are run to load data for the event. Templates can be written in any language supported by email-templates.
Requirements
- An available nodemailer transport (SMTP, AWS SES, etc).
Quick Examples
npm install bedrock-mail
const bedrock = require('bedrock');
const brMail = require('bedrock-mail');
const {config} = bedrock;
// configure default mail behavior
// defaults to send if NODE_ENV is 'production'
//config.mail.send = true;
// defaults for every message
config.mail.message = {
from: 'My Company Support <support@example.com>'
};
// setup SMTP transport
bedrock.config.mail.transport = {
type: 'smtp',
options: {
host: 'mail.example.com'
},
verify: true
};
// setup default template locals for all mails
bedrock.config.mail.locals.service = {
name: 'My Service',
url: 'https://example.com/'
};
// schedule generic event
bedrock.events.emitLater({
type: 'myModule.myEvent',
details: {
accountId: 1234,
image: 'https://example.com/images/2020-01-01.png'
}
});
// handle generic even and send email
bedrock.events.on('myModule.myEvent', async event => {
const account = await getAccount(event.accountId);
brMail.send({
template: 'myModule.myEvent',
message: {
to: account.email
},
locals: {
image: event.image
}
});
});
Example EJS subject template events/myModule.myEvent/subject.ejs
:
Here's your daily image from <%= service.name %>!
Example EJS html template events/myModule.myEvent/html.ejs
:
<html>
<body>
<p>Hello <%= account.name %>,</p>
<p>Here's your daily image:</p>
<p><img src="<%= image %>"></p>
<hr/>
<p><a href="<%= service.url %>"><%= service.name %></a></p>
</body>
</html>
Example EJS text template if the auto-generated one from HTML is not
sufficient events/myModule.myEvent/text.ejs
:
Hello <%= account.name %>,
Here's a link to your daily image:
<%= image %>
--
<%= service.name %>
<%= service.url %>
This template depends on the service
object and properties to be setup on a
global level. See the nodemailer docs if you want to add attachments,
embedded images, or use other features.
EJS includes work with file paths relative to the template. For example,
the text template example
that includes a text footer:
example/text.ejs
:
Welcome to our service!
<%- include('../common/footer.text.ejs') %>
common/footer.text.ejs
:
--
Example Service
https://example.com/
See the test directory for a full example.
Configuration
For documentation on configuration, see config.js, the example above, the test example, and the nodemailer and email-templates documentation.
API
async use('transport', transport)
Configure at runtime to use a specific transport configuration. Transport is
the same format as bedrock.config.mail.transport
.
async verify()
Call the transport verify()
method, if supported. See the nodemailer
documentation. Useful to check a SMTP connection works.
async send({template, message, locals})
Send mail using a specific template (name or path), message options, and local vars.
await brMail.send('my-template', {to: 'someone@example.com'}, {foo: 'bar'});
Testing
The test directory example tool can be used to test transports and templates.
