Asset Managers

Asset managers for combining/compressing JavaScript/CSS and for versioning your media files.

Features currently being evaluated

FeatureDescription
CSS compression Whether CSS files can be compressed
Combining Can concatenate/combine files into so-called bundles
Auto-regenerates Automatically regenerates/updates files and bundles when files change (during
development)
Image versioning Whether image files get versioned, too (or at least, whether it's compatible
with Django's ManifestStaticFilesStorage or CachedStaticFilesStorage).
JavaScript compression Whether JavaScript can be compressed
Dev mode Is a development mode available where files aren't combined/compressed (for
easier debugging)?
HTML5 manifest Can it auto-generate an HTML5 offline manifest file?
Sprites Can it generate sprites? Only data URIs aren't enough because they don't work
with all popular browsers.
Compressors List of supported JS/CSS compressors
Other features and notes Any other extra features
Manual regeneration Has a command for regenerating all asset bundles. (Used in production.)
Other languages Other supported languages (in addition to JavaScript and CSS)
Caching in dev mode Are assets properly cached when using runserver? This means there will be no
unnecessary HTTP requests (not even "if-modified-since"). This is important for
fast reloads with large web apps.
Cache Busting Adds version tag to file names for browser cache updates when content changes.
staticfiles-compatible URL rewriting In CSS files relative url() expressions stay valid no matter if you combine your
CSS files with this particular asset manager or if you use the same files
uncombined with django.contrib.staticfiles. This asset manager will correctly
rewrite relative URL paths when files are combined, even if the CSS files are
located in different subfolders at different depth levels.
Filter backends API Can it be extended via filter backends? This means *at least* being able to add
CSS compilers like Sass.
Gzips Pre-generates gzipped version of asset
Source Maps Does it support sourcemaps in the generated js/css?
Works in sandbox (e.g. App Engine) Whether it works in sandboxed environments like Google App Engine
