ValstroStarWars

The Star Wars API is a public REST API for making queries about the first 6 Star Wars films. The purpose of this assessment is to show that you can interact with a simple Websocket API(implementrued with Socket.io v4.

Requirements

• Produce a console/CLI application (the "Client App") that acts as a Socket.io client to the test server as described here
• The Client App must allow a user to search for arbitrary strings against the person/character search API
• The Client App works with the prepared clonardo/socketio-backend Docker image (representing the server)
• When search results are received, the names of the character that was matched ("name" field)+ their filmography ("films" field) should be printed to the console
• When any errors are received, they should be logged to the console
• The console should reset on completion of a search (on receipt of the last message in case of success, or on any error) to allow the user to make another search without restarting the application

Stack used:

• c#
• .net 6.0

Enviroment:

• Linux
• VS Code
• Docker Deslktop (run Socket.IO Server)

Libraries:

• SocketIO Client: https://github.com/doghappy/socket.io-client-csharp

Comments:

• Used main Socket.IO functions:
  • onConnected, .on, .onError, Dispose, onDisconnected
• I used a Queue to store the server response async.
• Then out of the listener I check if the transmition is ended and process the data in the Queue.
• If exists an error show it.

Improvements to do:

• Reconnection flow in case the server connection lost.
• Process to validate data if connection interrupted

Compile and Run

• start server: Run the following command at a terminal: docker run -p 3000:3000 clonardo/socketio-backend
• Requirements .net runtime 6.0
• Command /valstroStarWars$ dotnet run [enter]
