This project is set to create new usage charts for the game COH2. And also create web access to leaderboards, player cards and recent matches for players. The author of the game doesn't provide any global statistics. And online leaderboards has been shutdown recently.

This project is inspired by coh2chart.com which has data only for years 2016-2017 after which it was shut down.

Technical description

The project is created in Google Cloud with usage of Firebase. The main language of the project is set to be JavaScript. Which will be used on both FE and BE.

• FE - JavaScript, React
• BE - Serverless JS
• DB - FireStore (NoSQL DB)

GCP services to be used:

• Firebase Hosting - For hosting the website
• Firebase Firestore - NoSQL Database
• Firebase Cloud functions - Is the main backend for crawling and data processing
• GCP Pub/Sub - For messaging between the functions
• GCP Storage - For storing extra data

Thing to consider:

• There is a large amount of matches, we store them in the FireStore, however once you store the match. You don't do any changes to it, therefore it would be better to store them in the BigQuery where we could run our analysis more easily and it would be Faster and Cheaper.

CI/CD

Only web package is automatically deploy. Cloud functions need to be done manually for now.

Prod

Tagged versions are automatically deployed to https://coh2stats.com/
