Some Facts

Pricetag is an University project. Actually, We chose to make this because we didn't like the proposed one by the Professor so we came up with this challenging idea. Basically, the program works like CamelCamelCamel but the core part here is that all the prices are tracked by clients. That means when you search a product, firstly, pricetag will check if any of the connected client has already a more updated price timeline, if so all the data is sent to requester. Secondly it will make a request to lookup the product in Amazon. The project is made with Java for client side and Nodejs as a server side, to trace all clients and to make a peer-to-peer communication through sockets. Everything is possibile thanks to

How to use

Download and run it! Run java -jar downloaded.jar databasefile where databasefile is a file where pricetag will use as database to store products.

Actually you can omit the database file, that means everything will be stored in the memory and once you close the program all data will be erased: java -jar downloaded.jar

Note: if you are under Java 9, it may have problems. If so try to run: java --add-modules java.xml.bind -jar downloaded.jar databasefile
