UPC Lookup

A socket server using only the Elixir and Erlang Core libraries that allows you to look up the price and name for an item by the product's UPC.

Running Locally

• Clone the repo
• If you don't have Elixir setup, there is Docker configuration in the repo
  • Use docker-compose build to build the project and then docker-compose up to run the server with the default port of 4040
• Run PORT=4040 mix run --no-halt from the project root
• You should see a message saying the server is accepting connections

To test locally, open a telnet client connection to the server:

• telnet localhost 4040
• Send a UPC across the telnet connection and hit <Enter>
• You should see the price and name of the product returned

Demo App

If you just want to try out the lookup without cloning the repo you can open a TCP/IP socket connection to li1018-153.members.linode.com on port 4040. Telnet works well, but anything that can open a TCP/IP socket connection should work.

Test UPCs

Here are some of the UPCs I used while testing:

• 078913280024
• 041143051603
• 815301008439
