BuildPath

a tool for League of Legends champions runes and build paths

https://buildpath.win

Architecture

BuildPath is made of four components:

• a MongoDB document database
• patch_detector, a daemon which runs periodically to detect new League of Legends patch from official APIs
• match_collector, a daemon which runs periodically to collect matches from League of Legends challenger players on current patch, and generate statistics from those matches, saving them in the database
• frontend, which is a Nuxt.JS project hosting an API serving the statistics but also the full web frontend (Vue.JS)

Development

Getting started

Developing BuildPath requires Docker for a local MongoDB instance, and a NodeJS/npm installation. Then, for the first-time setup:

# Install npm and node
sudo apt install npm nodejs          # Ubuntu
sudo pacman -S npm nodejs            # Arch
sudo dnf install nodejs              # Fedora

# Install docker. Follow instructions on
# https://docs.docker.com/engine/install/
# .. and don't forget docker compose

cd dev && npm i && cd ..             # Install dependencies for the dev environment
cd frontend && npm i && cd ..        # Install dependencies for frontend
cd match_collector && npm i && cd .. # Install dependencies for match_collector
cd patch_detector && npm i && cd ..  # Install dependencies for patch_detector

BuildPath needs data to work, either for generating statistics in the match_collector or for the frontend.

In order to download a production snapshot with data, import them into a local MongoDB instance and re-generate champion statistics, just use:

node dev/scripts/setup-db.js

You can re-run the script to re-generate statistics, and it won't re-download data.

Afterwards, if you want to run the frontend:

cd frontend && npm run dev

Code quality

Every subproject has lint and format targets:

npm run format # Format code
npm run lint   # Run the linter

Please make sure those are run without errors before committing.
