# 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:
```bash
# 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:
```bash
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:
```bash
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.
