No-Op Compressors

The No-Op compressor don’t perform any operation, when used, only concatenation occurs. This is useful for debugging faulty concatenation due to poorly written javascript and other errors.

To use it, add this to your settings

PIPELINE['CSS_COMPRESSOR'] = 'pipeline.compressors.NoopCompressor'
PIPELINE['JS_COMPRESSOR'] = 'pipeline.compressors.NoopCompressor'

Write your own compressor class

You can write your own compressor class, for example if you want to implement other types of compressors.

To do so, you just have to create a class that inherits from pipeline.compressors.CompressorBase and implements compress_css and/or a compress_js when needed.

Finally, add it to PIPELINE['CSS_COMPRESSOR'] or PIPELINE['JS_COMPRESSOR'] settings (see Configuration for more information).

Example

A custom compressor for an imaginary compressor called jam

from pipeline.compressors import CompressorBase

class JamCompressor(CompressorBase):
  def compress_js(self, js):
    return jam.compress(js)

  def compress_css(self, css):
    return jam.compress(css)

Add it to your settings

PIPELINE['CSS_COMPRESSOR'] = 'jam.compressors.JamCompressor'
PIPELINE['JS_COMPRESSOR'] = 'jam.compressors.JamCompressor'
