Filesize Guard is a lightweight GitHub Action designed to prevent bloating your repository or downloadable app size by introducing large assets. It ensures assets exceeding a specified size limit are flagged, encouraging optimization or offloading to a CDN.

• Prevents large assets from being unintentionally added to the repository.
• Configurable size limit (default: 100 kB).
• Supports .gitignore-like syntax to exclude specific files or directories.

Create a GitHub Actions workflow in .github/workflows/filesize_guard.yml:

name: Filesize Guard
on:
  pull_request:
    branches:
      - main
  workflow_dispatch:

jobs:
  filesize_guard:
    runs-on: ubuntu-latest
    steps:
      - name: Filesize Guard
        uses: chris-rutkowski/filesize-guard@v1.0.3

Add a filesize_guard.ignore file to the root of your repository to define patterns for files or directories to exclude from size checks. The syntax follows .gitignore conventions.

Example filesize_guard.ignore:

test/*
logs/*
*.swift
*.kt
*.dart

Run the action manually using the workflow_dispatch event to scan and find large files in your repository.

name: Filesize Guard
on:
  workflow_dispatch:
  pull_request:

...

By default, the file size limit is set to 100 kB. You can customize this by passing the max_size_kb input:

steps:
  - name: Filesize Guard
    uses: chris-rutkowski/filesize-guard@v1.0.3
      with:
        max_size_kb: 50

steps:
  - name: Filesize Guard
    uses: chris-rutkowski/filesize-guard@v1.0.3
      with:
        ignore_file: ./my/path/my_filesize_guard.ignore
