Metro is a universal currency designed for Minecraft servers, in a mostly Krist-compatible API format.

⚠️ metro-server is not complete, and is in a development state. APIs may not function, and all content in the repo has not been tested. Further testing will be performed after record creation logic is completed.

⚠️ ALL commits past 8/2/2024 now follow the ametro-30-dbq-1 license

Running metro-server isn't hard to do in a development environment. In fact, you can do so in 6 steps.

• Create a .env file:
  • DBKEY: The password/key for the root MySQL user
  • BACKENDDBKEY: The password/key for the metroweb MySQL user
• Create /backend/badwords.txt: It's a normal text file, with one blocked phrase per line. An example is:

word1
word2
word3

This is not included in the repo for obvious reasons.

• Spin up Metro in Docker
• Execute init.sql in metro-server-db
• Create the user metroweb in MySQL

CREATE USER metroweb IDENTIFIED BY 'yourbackenddbkey1234';
GRANT ALL PRIVILEGES ON *.* TO metroweb;

• Restart metro-server-backend

• Finish API
• Address creation algorithm
• Reverse proxies (nginx)
• Documentation
• Automated testing
