nfl-data-loader

nfl-data-loader is a robust Python package for accessing, merging, and transforming NFL sports data from multiple sources in an object-oriented, pipeline-friendly way. It provides a unified API for teams, players, events, and venues, with rich schema documentation and ready-to-use data loaders, transformers, and formatters.

   [team, player, event, venue]  [Extract, Transform, Load Blocks and Pipelines]

🧩 Loader Groups

• Team: Team stats, rosters, schedules, advanced metrics
• Player: Player stats, depth charts, Madden ratings, combine data
• Event: Game-level stats, play-by-play, Vegas lines, EPA, fantasy
• Venue: Stadium/venue metadata and mappings

📑 Schemas & Data Dictionary

All endpoints return data validated by Pydantic schemas. See /schemas for:

• Field names, types, and descriptions (see schemas/events/features.py, schemas/players/madden.py, schemas/players/position.py)
• Example: Player Madden schema, event feature schema, position mappers

🛠️ Usage Example

from nfl_data_loader.api.sources.players.rosters.rosters import collect_roster
from nfl_data_loader.workflows.transforms.players.player import make_player_stats

# Load player roster for a season
roster_df = collect_roster(2024)

# Transform player stats
player_stats = make_player_stats(2024, week=1, position_group='quarterback')

📈 Data Flow Example

1. Load: Pull raw data from any source (e.g., ESPN, nflverse) or pull cached feature store (Event, Player)
2. Transform: Apply rolling averages, imputation, feature engineering
3. Format: Output as DataFrame, JSON, or for ML pipelines

🧪 Testing & Validation

• All endpoints are covered by tests (see /tests)
• Schemas are validated with Pydantic
• Linting and type checking enabled

🤖 CI/CD & PyPI Deployment

• GitHub Actions workflow auto-deploys to PyPI on merge to main
• See .github/workflows/publish.yml for details
