NAME

Dancer2::Plugin::Email - Simple email sending for Dancer2 applications

VERSION

version 0.0003

SYNOPSIS

use Dancer2;
use Dancer2::Plugin::Email;

post '/contact' => sub {
    email {
        from    => 'bob@foo.com',
        to      => 'sue@foo.com',
        subject => 'allo',
        body    => 'Dear Sue, ...',
        attach  => '/path/to/attachment',
    };
};

DESCRIPTION

This plugin tries to make sending emails from Dancer2 applications as simple as possible. It uses Email::Sender under the hood. In a lot of cases, no configuration is required. For example, if your app is hosted on a unix-like server with sendmail installed, calling email() will just do the right thing.

IMPORTANT: Version 1.x of this module is not backwards compatible with the 0.x versions. This module was originally built on Email::Stuff which was built on Email::Send which has been deprecated in favor of Email::Sender. Versions 1.x and on have be refactored to use Email::Sender. I have tried to keep the interface the same as much as possible. The main difference is the configuration. If there are features missing that you were using in older versions, then please let me know by creating an issue on github.

FUNCTIONS

This module by default exports the single function email.

email

This function sends an email. It takes a single argument, a hashref of parameters. Default values for the parameters may be provided in the headers section of the "CONFIGURATION". Paramaters provided to this function will override the corresponding configuration values if there is any overlap. An exception is thrown if sending the email fails, so wrapping calls to email with try/catch is recommended.

use Dancer2;
use Dancer2::Plugin::Email;
use Try::Tiny;

post '/contact' => sub {
    try {
        email {
            sender  => 'bounces-here@foo.com', # optional
            from    => 'bob@foo.com',
            to      => 'sue@foo.com, jane@foo.com',
            subject => 'allo',
            body    => 'Dear Sue, ...<img src="cid:blabla">',
            multipart => 'related', # optional, see below
            attach  => [
                '/path/to/attachment1',
                '/path/to/attachment2',
                {
                    Path => "/path/to/attachment3",
                    # Path is required when passing a hashref.
                    # See Mime::Entity for other optional values.
                    Id => "blabla",
                }
            ],
            type    => 'html', # can be 'html' or 'plain'
            # Optional extra headers
            headers => {
                "X-Mailer"          => 'This fine Dancer2 application',
                "X-Accept-Language" => 'en',
            }
        };
    } catch {
        error "Could not send email: $_";
    };
};

CONFIGURATION

No configuration is necessarily required. Email::Sender::Simple tries to make a good guess about how to send the message. It will usually try to use the sendmail program on unix-like systems and SMTP on Windows. However, you may explicitly configure a transport in your configuration. Only one transport may be configured. For documentation for the parameters of the transport, see the corresponding Email::Sender::Transport::* module. For example, the parameters available for the SMTP transport are documented here "ATTRIBUTES" in Email::Sender::Transport::SMTP.

You may also provide default headers in the configuration:

plugins:
  Email:
    # Set default headers (OPTIONAL)
    headers:
      sender: 'bounces-here@foo.com'
      from: 'bob@foo.com'
      subject: 'default subject'
      X-Mailer: 'MyDancer2 1.0'
      X-Accept-Language: 'en'
    # Explicity set a transport (OPTIONAL)
    transport:
      Sendmail:
        sendmail: '/usr/sbin/sendmail'

Example configuration for sending mail via Gmail:

plugins:
  Email:
    transport:
      SMTP:
        ssl: 1
        host: 'smtp.gmail.com'
        port: 465
        sasl_username: 'bob@gmail.com'
        sasl_password: 'secret'

Use the Sendmail transport using the sendmail program in the system path:

plugins:
  Email:
    transport:
      Sendmail:

Use the Sendmail transport with an explicit path to the sendmail program:

plugins:
  Email:
    transport:
      Sendmail:
        sendmail: '/usr/sbin/sendmail'

Multipart messages

You can embed images in HTML messages this way: first, set the type to html. Then pass the attachments as hashrefs, setting Path and Id. In the HTML body, refer to the attachment using the Id, prepending cid: in the src attribute. This works for popular webmail clients like Gmail and OE, but is not enough for Thunderbird, which wants a multipart/related mail, not the default multipart/mixed. You can fix this adding the multipart parameter set to related, which set the desired subtype when you pass attachments.

Example:

email {
    from      => $from,
    to        => $to,
    subject   => $subject,
    body      => q{<p>Image embedded: <img src="cid:mycid"/></p>},
    type      => 'html',
    attach    => [ { Id => 'mycid', Path => '/path/to/file' }],
    multipart => 'related'
};
