githubMetrics.js

// Lightweight metrics registry. Update this file monthly via a small script hitting GitHub APIs.
// Map pipeline 'name' (as in preLoadedObjects) to { repo: 'owner/name', lastCommit: 'YYYY-MM-DD', clones: number }
// If a pipeline lacks GitHub repo or metrics, omit it.

    // Example entries (fill with real data later):
    // "nf-core/mag": { repo: "nf-core/mag", lastCommit: "2025-09-01", clones: 12345 },
    // "MUFFIN": { repo: "BigDataBiology/MUFFIN", lastCommit: "2025-08-22", clones: 987 },

window.PIPELINE_GITHUB_METRICS = {
    // Example entries (fill with real data later):
    // "nf-core/mag": { repo: "nf-core/mag", lastCommit: "2025-09-01", clones: 12345 },
    // "MUFFIN": { repo: "BigDataBiology/MUFFIN", lastCommit: "2025-08-22", clones: 987 },
};


// --- GitHub Metrics Fetcher ---
// Usage: Call fetchGithubMetricsForPipelines(pipelineList) with an array of pipeline objects
// Each pipeline object should have a 'name' and 'repo' property
//
// To use a GitHub token securely:
// 1. Create a file named 'config.js' in this directory with the following content:
//    window.GITHUB_TOKEN = 'YOUR_GITHUB_TOKEN_HERE';
// 2. Add 'config.js' to your .gitignore so it is never pushed to GitHub.
// 3. The app will use window.GITHUB_TOKEN if present.

// Try to load token from config.js (should be loaded before this script)
const GITHUB_TOKEN = window.GITHUB_TOKEN || '';
