Fork of the extreme carpaccio kata, updated to use more recent libraries and fix some bugs

Extreme Carpaccio

This is a fork from dlresende/extreme-carpaccio.

French version here.

Extreme Carpaccio is a coding game designed to encourage and favour incremental development and Continuous Delivery best practices.

During a Extreme Carpaccio session, the facilitator uses his/her computer as a server and sends HTTP requests to participant machines (generally organised in teams). Each request is a purchasing order, like those you have when you buy something somewhere. Participants then calculate the order's total amount and send the correct response back to the server. For every correct response, the participant earns points and increases his/her score. For bad responses, penalties are charged and the participant loses points. Participants should slice (or decouple) the problem in order to deploy small chunks of the solution into production as soon as possible and then score before others. This is the purpose of this exercise: define a slicing strategy, implement, deploy, check feedback, adapt the strategy, implement, deploy... and iterate as fast as possible. Those who don't slice and try go to production only once the whole solution is implemented risk to spend too much time before scoring, leaving the way free to other teams win.

This workshop, kata, or coding game is intented to help teams to practice concepts like Continuous Delivery, Lean Startup, eXtreme Programming, Agile Development, and more.

Ready for the challenge?

If you are a participant, go to clients/ to get more instructions and start playing.

If you are a facilitator, go to server/ and find out how to facilitate a session.

Have fun :D

extreme-carpaccio's Issues

Server should be able to pick the reduction from a list

Currently in the configuration file we can put only one type of reduction at the time (see reduction configuration). We should be able to use an array of reductions.

Definition of done

• Replace the "reduction" field by an array in the configuration file
• If the picked reduction is not known we fallback to "STANDARD" (current behaviour) to prevent crash from typo in the config file.
• Add tests

To be discussed

• Do we randomly pick a reduction or we can weight them?

Rewrite the server frontend using a modern stack

Currently the server frontend is using React 0.12 and jQuery. This a working but the stack is outdated and it is not easy to add new features in the UI.

Definition of done

• Use the latest version of React for the server UI
• Add tests to prevent any regression

Suggestion

• Use Turborepo for a clean monorepo with a backend app and a frontend app (#5)

Server doesn't send request to clients using https

If a client register with an https schema the server fails to send request to it.

This is probably due to the fact that we use node:http in every case when we should use node:https when the client is using https.

Backup current state of the game

Add a backup of the game to allow to restart it at a specific state. This can be useful if the server crash or the laptop shutdown (battery issue for example).

Definition of done

• The server can start without a backup
• If a backup is present it will load it as an initial state
• Add tests on both cases
• The backup must not be commited in the repository

Suggestions

To save the state you could use SQLite or a JSON file.
