CarsBot : Cars24 Hackathon code

This is submission code for CARS24 Hackathon. This is a sample chatbot, consisting of Google Dialogflow agent, a NodeJS Server and web interface, which can help users in buying and selling of cars. If the bot is not successfull in answering the user request it forwards the request to a human agent.

This is code is forked and developed on top of Google dialogflow Sample App.

Features

Agent will escalate to a human operator on-demand
Agent will escalate to a human operator after repeated failure to match an intent
Server routes conversation between agent and human operator depending on context
Server supports multiple concurrent conversations between customer, agent and operator
Customer web client supports real-time chat with agent or operator
Operator web client supports real-time observation and participation in multiple customer conversations
Operator web client demonstrates alerting of operator in case of customer escalation

Limitations

There is no authentication of customers or operators. In this limited demonstration, communication between users is not secure. This code is provided as an example, not a finished solution.
Active conversations are stored in-memory with no on-disk persistence (though code could easily be modified to support this).
Operators can only monitor and communicate with customers that have subsequently connected. Previously connected customers are ignored.
User interface is very rudimentary.
