A simple POC for an email tracking app. Has 3 API's

1. Subscribe API - accepts raw JSON input with only one parameter of email with a value of the email address whom we want to add to our subscription database.

Example input: { email: "[email protected]" }

2. Image api - accepts two params using a get request, the first one being the API key and the second one being the filename requested. The system leverages the JSON Web Token api to fetch encrypted data to avoid a db search request.

Example URL call: https://$HOST/$apikey/$filename

It is recommended to use an https server, because most email clients will reject the image. I recommended using c9.io to run this project because they support https requests.

3. Logs api - Implemented temporarily to check the log file.

Example URL call: https://$HOST/logs

Installation Steps:

1. Clone the repo.
2. Create a logs folder in root and create an empty file logs.txt inside that logs folder.
3. Add email details in config/emailConfig.js file.
4. run npm install
5. run npm start
