Application Sequence

1. Client -Upload file via POST to /job - job _id is returned
2. API - adds a message to queue
3. Worker - receive the message off the queue
4. Worker - processes file and updates database
5. Client - Polls via GET to /job/{_id}

Things to note

• Basic demo has been setup - navigate to http://localhost:3000/demo
• Only images are supported currently - PDF input will come later
• Worker will eventually become its own standalone project
