🔄 Purge Camo Cache




  Keep your GitHub images fresh!


  A GitHub Action that purges cached images served via camo.githubusercontent.com.



---

## ❓ Why?

GitHub uses **Camo** as a caching proxy to serve images securely. But Camo doesn't refresh images automatically — so your badges and images can stay stale for hours. This action forces a cache purge so updates show up instantly. ⚡

## 🚀 Quick Start

Add this workflow to your repository:

```yaml

name: Purge Camo Cache

on:

  push:

    branches:

      - main

  schedule:

    - cron: '0 */2 * * *'

jobs:

  purge-camo-cache:

    runs-on: ubuntu-latest

    steps:

      - name: Purge Camo Cache

        uses: Angrido/Purge-Camo-Cache@v1.3.0

```

🔒 For **private repositories**, pass a token with read access:

```yaml

      - name: Purge Camo Cache

        uses: Angrido/Purge-Camo-Cache@v1.3.0

        with:

          token: ${{ secrets.GITHUB_TOKEN }}

```

## 📥 Inputs

| Name    | Required | Default              | Description                       |

|---------|----------|----------------------|-----------------------------------|

| `token` | No       | `${{ github.token }}` | 🔑 GitHub token for authentication. |

## ⚙️ How It Works

1. 🌿 Detects the current branch using `tj-actions/branch-names`.

2. 🔍 Fetches the repository page and extracts all `camo.githubusercontent.com` image URLs.

3. 🧹 Sends a `PURGE` request to each URL to invalidate the cache.
