core

Overview

• This project provides an open platform (backend) with Dota-related data (matches, players, etc.)
• Raw data comes from the WebAPI provided by Valve and fully automated parsing of match replays (.dem files).
• A public deployment of this code is maintained by The OpenDota Project.

Tech Stack

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

Quickstart (Docker)

Running the server

• Install Docker: curl -sSL https://get.docker.com/ | sh. If you are on Windows, make sure you shared the working drive with Docker.
• Create .env file with required config values in KEY=VALUE format (see config.js for a full listing of options) cp .env_example .env
  • STEAM_API_KEY You need this in order to access the Steam Web API.
  • STEAM_USER, STEAM_PASS The retriever requires a Steam account in order to fetch replay salts. It is recommended to use 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.
• Start containers and initialize databases: docker-compose up.
• You can now access the website at http://localhost:5000 (or the hostname of the instance running the code)

Developing the server

• File changes you make outside the container should be automatically mirrored to the container.
• 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.

Other information

• Get a terminal into the running container: docker exec -it odota-core bash
• The process manager pm2 is used to manage the individual services. Each is run as a single Node.js process.
  • pm2 list See the currently running services.
  • pm2 start manifest.json Start all the services.
  • pm2 start svc/web.js --watch This starts a specific service and watches it for changes.
  • pm2 logs web Inspect the output of a service.
  • pm2 delete all Stop and remove all the services.
• Tests
  • npm test runs the full test suite. Use mocha for more fine-grained control over the tests you want to run.
• Get some starter data
  • You can request some parses by ID to get some parsed data.
  • You can also run scanner to get some matches from the API.
