mailer-template

Basic node module to send mails based on templates. It depends on nodemailer to stablish connection with the mail server and mustache to render the mail body from the template.

You have top provide in a given directory a set of mail templates. For each temaplate at least two files need to be provided:

• body: <template>.html.mst
• options: <template>.json

where <template> is the name of the template.

You can also provide a body in text format in the file <template>.text.mst but this file is optional. If the file is not provided a text version is generated from the html using the package html-to-text

The file <template>.json should contain a json object with a set of options to be used while sending the email, this json object should contains at least a fiel subject with the template for the subject for the emil.
