bragg-sns

SNS middleware for bragg.

This little piece of middleware makes it possible to handle SNS events as if they where normal requests.

Install

$ npm install --save bragg-sns

Usage

const app = require('bragg')();
const router = require('bragg-router')();
const sns = require('bragg-sns');

// Listen for events in the `TopicName` topic
router.post('sns:TopicName', ctx => {
    ctx.body = ctx.request.body;
});

app.use(sns());
app.use(router.routes());

exports.handler = app.listen();

The sns: prefix is attached by this module and is followed by the name of the topic that originated the event. The message of the event is provided in the body property of the request object.

Mapping

It's also possible to provide a mapping object or function to transform one topic to another.

With an object, it will look like this.

// Data on the `TopicNameDev` topic will be posted on the `sns:TopicName` handler
app.use(sns({TopicNameDev: 'TopicName'}));

With a function, it looks like this.

// Data on the `TopicNameDev` topic will be posted on the `sns:TopicName` handler
app.use(sns(topic => topic.replace(/Dev$/, '')));
