# GitHub Stats Action

A GitHub Action that collects comprehensive statistics for a user's GitHub profile and outputs them to a JSON file. Perfect for building profile READMEs, dashboards, or personal analytics.

## Features

- **Profile Data**: Name, bio, company, location, social links
- **Contribution Stats**: Total contributions, streaks, most active day, monthly breakdown
- **Repository Metrics**: Stars, forks, views, top repositories
- **Code Statistics**: Lines added/deleted, commit counts, languages with percentages
- **Social Stats**: Followers, following, stars given
- **Activity Data**: Pull requests, issues, PR reviews, discussions

## Requirements

### Personal Access Token (PAT)

This action **requires a Personal Access Token** - the default `GITHUB_TOKEN` will not work because:

- Contribution calendar data requires authentication as the actual user
- Repository view counts require push access across all repositories
- The `viewer` GraphQL query returns data for the token owner

#### Required PAT Scopes

| Scope | Purpose |
|-------|---------|
| `read:user` | Access user profile data |
| `repo` | Access repository statistics, views, and private repos |

#### Creating a PAT

1. Go to [GitHub Settings → Developer settings → Personal access tokens → Fine-grained tokens](https://github.com/settings/tokens?type=beta)
2. Click "Generate new token"
3. Select the scopes listed above
4. Copy the token and add it as a repository secret (e.g., `USER_PAT`)

## Usage

### Basic Workflow

Create `.github/workflows/stats.yaml`:

```yaml
name: Collect GitHub Stats

on:
  schedule:
    - cron: '0 0 * * *'  # Run daily at midnight
  workflow_dispatch:      # Allow manual trigger

jobs:
  collect-stats:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Collect GitHub Stats
        uses: LukeHagar/stats-action@v1
        env:
          GITHUB_TOKEN: ${{ secrets.USER_PAT }}

      - name: Commit stats
        uses: stefanzweifel/git-auto-commit-action@v5
        with:
          commit_message: "chore: update github stats"
          file_pattern: github-user-stats.json
```

### Template Repository

For a complete setup with visualization, use the [stats template repository](https://github.com/LukeHagar/stats/).
