Compress and minify Flask responses!

Project description


Flask-Squeeze is a Flask extension that automatically:

  • Minifies JS and CSS responses.
  • Compresses all HTTP responses with brotli.
  • Caches static files so that they don't have to be re-compressed. The cache will be cleared each time Flask restarts! Files are considered to be static if they are contained in a directory that is named "static" (Or generally, if they contain the word "static" in their file path.


pip3 install Flask-Squeeze


from flask_squeeze import Squeeze
squeeze = Squeeze()

# Initialize Extension

Thats all!


You can configure Flask-Squeeze with the following options in your Flask config:

  • COMPRESS_FLAG (default=True): Globally enables or disables Flask-Squeeze
  • COMPRESS_MIN_SIZE (default=500): Defines the minimum file size in bytes to activate the brotli compression
  • COMPRESS_LEVEL_STATIC (default=11): Possible value are 0 (lowest) to 11 (highest). Defines the compression level of brotli for files in static folders. Theses files fill also be cached, so that they only have to be compressed once.
  • COMPRESS_LEVEL_DYNAMIC (default=5): Possible value are 0 (lowest) to 11 (highest). Defines the compression level of brotli for dynamic files like generated HTML files. Theses files will not be cached, so they will be compressed for each response.
  • COMPRESS_VERBOSE_LOGGING (default=False): Enable or disable verbose logging. If enabled, Flask-Squeeze will print what it does into the terminal in a highlighted color.
