koa-ses

A middleware for Koa to receive and handle sns notifications Amazon SNS from Amazon SES.

## Setup

npm i koa-ses -S

Usage

Important: To receive notifications in your koa app you should have configured previously SNS with SES in your AWS account. Check docs for more info.

var koa = require('koa');
var koaSES = require('koa-ses');

var app = koa();

// Create a function that will receive the
// notification data coming from AWS. This is required
var notificationHandler = function * (message){
	// Your own logic to handle the notification
};

app.use(koaSES(notificationHandler, options));

With your own implementation sending emails by SES. You need to store the messageId in db/somewhere to use it later as the reference in the callback. Remember the callback receives the messageId you previously stored when sending the email for the first time.

• messageId: id of the SES email on AWS.
• serviceStatus: SES Status of the email. ['Delivery', 'Bounce', 'Complaint']
• from
• status: Simplified status. ['Sent', 'Failed']
• destination
