Crow Emissary

Crow Emissary is a simple module to send emails through different strategies.

#### Warning

This module is very beta and should not be used in production yet. Feel free to contribute if you liked the idea.

Getting Started

First of all, you must add Crow Emissary to your project:

``shell
npm install crow-emissary --save
`

Then you add it into your application, with the strategy that you want to use to send emails.
Simple as that:
`javascript
const Strategy = require('crow-emissary/lib/strategies/Strategy')(CREDENTIAL);
const crow = require('crow-emissary')(Strategy);
...
let settings = {...}; // fromEmail, toEmail, subject...
crow.send(settings);
`

#### Authentication

Those strategies demands token or some other way of authentication. Soon I'll update this doc with the specs about how to implement it at these strategies.

Strategies

The idea of this module is to encapsulate different send email algorithms into a common api. All you have to do is to instantiate the strategy/algorithm that you want to use and call the Crow passing it as parameter.

#### Sendgrid Strategy
`javascript
const Sendgrid = require('crow-emissary/lib/strategies/Sendgrid')(process.env.SENDGRID_API_KEY);
const crow = require('crow-emissary')(Sendgrid);
...
let settings = {
fromName: 'Michel Temer',
fromEmail: 'michel@golpistas.org.br',
toEmail: 'joesley@jbs.com.br',
subject: 'Tem que manter isso, viu?!',
type: 'text/html',
content: '

Fora, Temer!

'
}
crow.send(settings);
`

#### AWS SES Strategy
`javascript
const AwsSES = require('crow-emissary/lib/strategies/AwsSES')('/path/to/credentials.json');
const crow = require('crow-emissary')(AwsSES);
...
let settings = {
fromName: 'Michel Temer',
fromEmail: 'michel@golpistas.org.br',
toEmail: 'joesley@jbs.com.br',
subject: 'Tem que manter isso, viu?!',
type: 'text/html',
content: '

Fora, Temer!

'
}
crow.send(settings);
``

Issues

If you find any kind of issue, please feel free to report at issue so I can correct it.
And, of course, you all are welcome to make a pull request.

Next Steps

* Refactor the way of import strategies;
* Implement Unit Tests;
* Implement more strategies;
* Increase the feature of use template engines to compile html emails from model;
