A League of Legends statistics API built with AdonisJS v6.
Personal project. I wanted a fast, no-fluff League of Legends stats app, so I built one. The live version runs at invade.lol - feel free to try it out before setting up locally.

- Framework - AdonisJS v6
- Databases - PostgreSQL (player data) + ClickHouse (match analytics)
- Cache - Redis
- Storage - S3-compatible (MinIO locally, Cloudflare R2 in production)
- Data source - Riot Games API
Search still accepts Name#Tag, and profiles keep the /:player URL
(/<GameName>-<TagLine>). No region selector is needed. Typeahead searches
stored players across regions, including non-Latin names; entering a full Riot ID
also resolves players who are not stored yet.
The backend resolves the Riot ID to a PUUID, then checks supported League platforms until it finds the profile. A saved platform or a recognizable tag is only a priority hint, not an authoritative region. Custom tags work too. Only 404 responses advance to another platform; key, rate-limit, and service errors are preserved. Concurrent lookups for the same ID are coalesced, and successful results are persisted so subsequent visits avoid discovery calls.
Account routing is separate from match routing (Oceania and Southeast Asia use SEA for matches). PH2 and TH2 are normalized to SG2. Refresh detects server transfers and routes match requests using the newly resolved platform. See Riot's routing documentation.
GET /api/summoners/:summoner detects the platform automatically. The existing
GET /api/summoners/:platform/:summoner API remains available. For
POST /api/summoners/sync, omit platform to detect it automatically; a valid
profile with no new matches returns 200 with an empty matches array.
Run node ace migration:run when upgrading to add the index used by regionless
profile lookups. Keep RIOT_API_KEY in the server environment or ignored .env.

1. Clone
git clone https://github.com/invadelol/core.git
cd core2. Fill in secrets
make devOn first run, make dev creates .env from .env.example and stops.
Open .env and fill in two values:
APP_KEY- runnode ace generate:keyto get oneRIOT_API_KEY- get a key at https://developer.riotgames.com
Everything else is pre-filled with local defaults.
3. Start
make devThat's it. make dev installs dependencies, starts Docker services (PostgreSQL,
ClickHouse, Redis, MinIO), waits for them to be ready, runs migrations, and
launches the dev server.
The API is available at http://localhost:3333.

The app ships a light and a dark theme, both designed rather than derived. The
theme follows the operating system by default and can be set explicitly from
the header; the choice is stored in localStorage and replayed before first
paint, so there is no flash.
Structure comes from rules and spacing rather than nested cards, five hues carry all the meaning, and Riot's own role glyphs are used wherever a lane is named.
See docs/design.md for the palette and primitives, and docs/player-profile.md for what each page shows.
