Alinex Mail: Readme

An easy to use module for sending mails.

• fully configurable
• configuration templates
• using markdown with auto text/html creation
• support for handlebars templates

While sending mails it will also transform inline images in html into cid images attached to the mail to make it more standard conform.

It is one of the modules of the Alinex Namespace following the code standards defined in the General Docs.

Read the complete documentation under https://alinex.github.io/node-mail.

Install

The easiest way is to let npm add the module directly to your modules (from within you node modules directory):

npm install alinex-mail --save

And update it to the latest version later:

npm update alinex-mail --save

This package will install a lot of subpackages to ensure the full functionality but only the ones really needed are loaded on demand.

Always have a look at the latest changes.

Usage

The first step is to load the module:

mail = require 'alinex-mail'

And now you simply send your mails:

mail.send
  base: 'default'
  subject: 'Test'
, context, (err) ->
  # handling of errors or success 

The above setup is all you may need to send an email. All the missing information is taken from it's base. Which is like always defined as a configuration setting.

The context is optional and only used if the mail's body contains handlebars templates.

If you want to validate email settings within you applications configuration, you may use the schema from this package:

emailSchema = require('alinex-mail/lib/configSchema').email

You may also resolve the email templates before sending it:

setup = mail.resolve setup

Configuration

The configuration is based on multiple email templates. They can be made on top of each other.

They will be defined under /email and an example may look like:

# Email Templates 
# ================================================= 
 
 
# Default Email Templates 
# ------------------------------------------------- 
# This will extend/overwrite the already existing setup within the code. 
default:
  # specify how to connect to the server 
  transport: smtp://alexander.schilling%40mycompany.de:<PASSWORD>@mail.mycompany.de
  # specify retries 
  retry:
    times: 1 # makes 2 tries at max 
    interval: 5s
  # sender address 
  from: [e-mail]
  replyTo: [e-mail]
 
  # content 
  locale: en
  subject: >
    Database Report: {{name}}
  body: |+
    {{conf.title}}
    ==========================================================================
 
    {{conf.description}}
 
    Started at {{dateFormat date "LLL"}}:
 
    | Zeilen | Datei    | Beschreibung |
    | ------:| -------- | ------------ |
    {{#each result}}
    | {{rows}} | {{file}} | {{description}} |
    {{/each}}
 
    Find the files attached to your mail if data available!

To make it more modular you may also add a base setting to use the setting defined there as a base and the options here may overwrite or enhance the base setup.

Read more at the {@link configSchema.coffee} page.

Debugging

If you have any problems you may always run it with debugging by setting the DEBUG environment variable like:

DEBUG=mail* myprog-usingsshtunnel

The following targets are possible:

• mail general logging
• mail:data output all mail elements instead of only the envelope

If you enable debugging of mail the given configuration will also be validated.
