Installation

pip install django-manifeststaticfiles-enhanced

Usage

Basic Usage

Replace Django's default ManifestStaticFilesStorage with the enhanced version using the STORAGES setting:

# settings.py
STORAGES = {
    "staticfiles": {
        "BACKEND": "django_manifeststaticfiles_enhanced.storage.EnhancedManifestStaticFilesStorage",
    },
}

Configuration Options

keep_original_files (ticket_27929)

Control whether original files are kept after hashing:

# settings.py - Keep original files (default)
STORAGES = {
    "staticfiles": {
        "BACKEND": "django_manifeststaticfiles_enhanced.storage.EnhancedManifestStaticFilesStorage",
        "OPTIONS": {
            "keep_original_files": True,  # Default
        },
    },
}

# Or delete original files to save space
STORAGES = {
    "staticfiles": {
        "BACKEND": "django_manifeststaticfiles_enhanced.storage.EnhancedManifestStaticFilesStorage",
        "OPTIONS": {
            "keep_original_files": False,
        },
    },
}

JavaScript Module Support (ticket_34322)

Disable ES module import/export processing:

# settings.py
STORAGES = {
    "staticfiles": {
        "BACKEND": "django_manifeststaticfiles_enhanced.storage.EnhancedManifestStaticFilesStorage",
        "OPTIONS": {
            "support_js_module_import_aggregation": False,
        },
    },
}

Easy access to existing options

Disable manifest_strict

# settings.py
STORAGES = {
    "staticfiles": {
        "BACKEND": "django_manifeststaticfiles_enhanced.storage.EnhancedManifestStaticFilesStorage",
        "OPTIONS": {
            "manifest_strict": False,
        },
    },
}

Also available:

• max_post_process_passes
• manifest_name: change the name of the staticfiles.json file

Feature Details

CSS Processing Improvements (ticket_21080)

CSS URL processing uses a proper lexer instead of regex, providing:

• Ignores url's in comments
• More reliable URL extraction
• Wider @import support

File Operation Optimization (ticket_28200)

Reduces unnecessary file operations during collectstatic:

• Avoids recreating files that haven't changed
• Checks file existence before deletion

JavaScript Module Support (ticket_34322)

Enabled by default:

• Processes ES6 import/export statements
• Handles dynamic imports
• Updates module paths to hashed versions

Example JavaScript that gets processed:

// Before processing
import { Component } from './component.js';
export { utils } from './utils.js';

// After processing (with hashing)
import { Component } from './component.abc123.js';
export { utils } from './utils.def456.js';

Option to not move the origianl asset to your static folder (ticket_27929)

Control file cleanup behavior:

# Keep original files (default)
keep_original_files = True
# Results in: style.css + style.abc123.css

# Delete original files
keep_original_files = False  
# Results in: style.abc123.css only

Running Tests

# Install development dependencies
pip install -e .[dev]

# Run tests
python runtests.py

# Or run specific test modules
python runtests.py tests.staticfiles_tests.test_storage

Migration from Django's ManifestStaticFilesStorage

This package is designed as a drop-in replacement:

1. Install the package
2. Update your STORAGES setting
3. Run python manage.py collectstatic as usual

All existing functionality remains the same, with additional features available through configuration options.
