Stocker - socket.io auto instrumentation demo

Stocker allows clients to search for stocks and then subscribe for stock symbol price updates

The app is composed of 2 parts

• socket.io + express server
• socket.io-client app

Server

Endpoints:

• /search HTTP GET endpoint for searching for a stock
• socket.io register event listener that receives a stock symbol and notifies the client when a price update arrives

Client

The client is calling the server search api with the hard coded value APPL and then registering the response symbol for updates
