Open source Dota 2 replay parsing and statistics

YASP (Yet Another Stats Page)

Overview

• This project aims to provide free, open source, highly detailed match and player statistics for the Dota 2 community.
• Data comes from the WebAPI provided by Valve and fully automated parsing of match replays (.dem files).
• See here for an example of our match analysis (this match may not have the latest features as we're constantly adding new things).

Tech Stack

• Web/Microservices: Node.js
• Storage: PostgreSQL/Redis
• Parser: Java (powered by clarity)

Quickstart

• We recommend Cloud 9 IDE for fast and easy setup and development, although you are free to develop on your own setup if you want.
• Create an account on Cloud 9: https://c9.io/dashboard.html
• Start a new workspace and choose the source GitHub repository as yasp-dota/yasp, or your own fork of it if you're planning to make changes and submit a pull request.
• Open the workspace
• Install dependencies: sudo bash init.sh. The script is designed for Ubuntu 14.04 LTS. For other platforms, please have a look at the wiki.
• Create .env file with required config values in KEY=VALUE format (see config.js for a full listing of options) cp .env_example .env
  • The retriever requires a Steam account in order to fetch replay salts. We recommend creating a new account for this purpose (you won't be able to log into the account while the retriever is using it). If you don't care about getting replay salts/downloading replays then you can skip this step.
• Set up the database sudo npm run create
• Build npm run build
• Run the application with one of the following: (this will run under nodemon so file changes automatically restart the server):
  • npm run dev Run one instance of each service.
  • npm run dev web Runs just the web server. Useful for developing just the frontend CSS/JS.
  • npm run dev web,parser,requests,retriever The minimal setup for being able to open the site in a browser and request parses by ID (which is a useful end-to-end test).
• Other useful commands
  • npm run watch: If you want to make changes to client side JS, you will want to run the watch script in a separate window in order to automatically rebuild after making changes.
  • npm test runs the full test suite. Use mocha for more fine-grained control over the tests you want to run.
  • npm run task updateconstants pulls latest constants data and saves to json directory.
  • npm run task fullhistory queues a full history request for all players in DB who don't have it yet.
  • npm run update updates all deps in package.json to latest versions.
• Get some starter data
  • You can request some parses by ID to get some parsed data.
  • You can also log in through Steam on your own instance to trigger a full history request for that user (requires fullhistory service to be running)
• Make some changes and commit them: git add --all; git commit -m "My first commit!"
• Submit a pull request. Wait for it to be reviewed and merged.
• Congratulations! You're a contributor.
