🔧 Advanced Configuration

Pattern Matching

The action supports powerful glob patterns:

• **/* - All files recursively
• *.js - All JavaScript files in current directory
• src/**/*.{js,ts} - All JS/TS files in src directory
• !**/*.test.js - Exclude test files (when used in exclude)

Concurrency Tuning

Adjust concurrency based on your needs:

• Small files: Higher concurrency (20-50)
• Large files: Lower concurrency (5-10)
• Network limited: Conservative (3-5)

Storage Classes

• STANDARD: Frequently accessed data
• WARM: Infrequently accessed data
• COLD: Long-term archival

URL Generation

The action automatically generates URLs for uploaded files:

• Public files (public_read: true): Direct URLs that can be accessed immediately
• Private files: Pre-signed URLs valid for 1 hour that provide temporary access

URLs are available in two outputs:

• upload_urls: JSON array of all uploaded file URLs
• first_upload_url: Direct access to the first uploaded file URL (useful for single file uploads)

Example of using URLs in subsequent steps:

- name: Upload and deploy
  id: upload
  uses: diverger/gh-obs-helper@v1
  with:
    # ... upload configuration
    public_read: true

- name: Update deployment
  run: |
    curl -X POST "${{ env.DEPLOY_WEBHOOK }}" \
      -d "url=${{ steps.upload.outputs.first_upload_url }}"
