This application implements an email pixel tracking system. There are two main APIs, the pixel provisioning API and the tracking API. Both are implemented in a single app for simplicity.

The system is built for multi-tenant SaaS deployment, an account login id is required to begin provisioning tracking pixels. For e.g., to create a new tracking pixel a user of an account ("User") with login id "foo" will POST to /foo/pixel and retrieve pixel markup with GET /foo/pixel/:rid.

• Setup
• Running locally
• Running the tests

To run the server, you need to do the following:

1. Install node.js 8.x and npm.

2. Install dependencies:

   npm install

npm start

npm test

1. Create a recipient and associate with the pre-existing "pcio" account:

$ curl -v http://localhost:8080/pcio/pixel -H 'Content-Type: application/json' --data '{"email": "[email protected]"}'

1. Retrieve the markup template to be included in an email to the recipient:

$ curl -v http://localhost:8080/pcio/pixel/1

(This should be the same URL as returned in the Location header of the first request)

1. Simulate an email opening for the first time on a device:

$ curl -v 'http://localhost:8080/v?u=1&aid=pcio'

1. Simulate an email open on a repeat device:

$ curl -v --cookie "rid=1" 'http://localhost:8080/v?u=1&aid=pcio'
