Package: django-strip-whitespace
HTML Whitespace remover for DjangoIntroduction :A powerful tool to optimize Django rendered templatesWhy use “django_stip_whitespace” ?Adds line break to InlineJS.It can automagically minify inline CSS, JS.Removes <!–prettier-ignore–> from HTML.It speeds up website by reducing the HTML size.Drop in replacement for django.gzip.GzipMiddleware.It compiles regex at runtime. So it’s blazing fast.Its mostly based on C ( gzip ) and Rust (minify-html) libraries.Significantly lower bytes transferred when working with frameworks like AlpineJs ( Almost fully working & Please open a issue in theIssue Trackerif you encounter any bug) & Petite Vue.Is very customizable. ( You can configure lower levelminify-htmlrust bindings and also the lower levelpythonbindings from settings.py )Why souldn’t you use “django_stip_whitespace” ?You don’t like having unnecessary ‘;;’ in your HTML. ( If you know any regex to fix this please put a pull request )Although I tried my best to use Compiled Language for Optimizations. It can still be sub miliseconds ( > 0.001 ) slower compared to normal Django Rendering. ( If you know any way to improve performance, please put a pull request )Requirements :python-strip-whitespaceDjango > 3 ( Should work with version 2? )Python 3 ( Should work with all version? )Brotli ( or BrotliPy ) | ( Optional )ZSTD ( Optional )User guide :Installation :Install with pip from pypi (No extra dependencies):$ python -m pip install django_strip_whitespaceInstall with pip with Brotli support:$ python -m pip install django_strip_whitespace[brotli]Same but with Zstandard support:$ python -m pip install django_strip_whitespace[zstd]Install with pip from github ( Development | Not Recommended for Production ):$ python -m pip install https://codeload.github.com/baseplate-admin/django_strip_whitespace/zip/refs/heads/mainThen include it in your django project:MIDDLEWARE=[..."strip_whitespace.middlewares.HtmlStripWhiteSpaceMiddleware.html_strip_whitespace",]Or if you like:MIDDLEWARE+="strip_whitespace.middlewares.HtmlStripWhiteSpaceMiddleware.html_strip_whitespace"Customization :Change Lower Level Bindings :Rust :The module allowsrustminifier options to be changed from Django’s settings.py file. If you would like to change any settings, refer tominify-html’ssource code.The bindings are ( by default set to True ):STRIP_WHITESPACE_RUST_DO_NOT_MINIFY_DOCTYPE,# passes do_not_minify_doctype to minify-htmlSTRIP_WHITESPACE_RUST_ENSURE_SPEC_CONPLIANT_UNQUOTED_ATTRIBUTE_VALUES,# passes ensure_spec_compliant_unquoted_attribute_values to minify-htmlSTRIP_WHITESPACE_RUST_KEEP_CLOSING_TAGS,# passes keep_closing_tags to minify-htmlSTRIP_WHITESPACE_RUST_KEEP_COMMENTS,# passes keep_comments to minify-htmlSTRIP_WHITESPACE_RUST_KEEP_HTML_AND_HEAD_OPENING_TAGS,# passes keep_html_and_head_opening_tags to minify-htmlSTRIP_WHITESPACE_RUST_KEEP_SPACES_BETWEEN_ATTRIBUTES,# passes keep_spaces_between_attributes to minify-htmlSTRIP_WHITESPACE_RUST_MINIFY_CSS,# passes minify_css to minify-htmlSTRIP_WHITESPACE_RUST_MINIFY_JS,# passes minify_js to minify-htmlSTRIP_WHITESPACE_RUST_REMOVE_BANGS,# passes remove_bangs to minify-htmlSTRIP_WHITESPACE_RUST_REMOVE_PROCESSING_INSTRUCTIONS,# passes remove_processing_instructions to minify-htmlIf you would like to change any of the above variables, simply put them in settings.py ( Please note that every variable here is a python boolean ).For example:# settings.pySTRIP_WHITESPACE_RUST_DO_NOT_MINIFY_DOCTYPE=FalsePython :The module allows python minifier options to be changed from Django’s settings.py file. If you would like to change any settings, refer topython-module’ssource code.The bindings are ( by default set to a sane value ):STRIP_WHITESPACE_PYTHON_REMOVE_COMMENTS,# False | removes comments from HTML using python ( not recommended cause rust can do that just fine and fast )STRIP_WHITESPACE_PYTHON_CONDENSE_STYLE_FROM_HTML,# True | replaces '<style text/css>' -> '<style>'STRIP_WHITESPACE_PYTHON_CONDENSE_SCRIPT_FROM_HTML,# True | replaces '<script text/javascript>' -> '<script>'STRIP_WHITESPACE_PYTHON_CLEAN_UNNEEDED_HTML_TAGS,# True | removes some unnecessary tagsSTRIP_WHITESPACE_PYTHON_CONDENSE_HTML_WHITESPACE,# True | This is where the magic happens.STRIP_WHITESPACE_PYTHON_UNQUOTE_HTML_ATTRIBUTES,# True | This is also a magic module.If you would like to change any of the above variables, simply put them in settings.py ( Please note that every variable here is a python boolean )For example:# settings.pySTRIP_WHITESPACE_PYTHON_REMOVE_COMMENTS=TrueChange Ignored Paths :This module allows dynamic ignored path allocation.
So for example if your sitemap.xml is at url ‘/sitemap.xml’ and you want to avoid minifying it ( Because this module in lower level is meant to minify HTML not XML ).
Then you can add it to ignored path. ( By default it ignores ‘/sitemap.xml’ )To customize ignored path:# settings.pySTRIP_WHITESPACE_MINIFY_IGNORED_PATHS.append("/robots.txt")# Note that STRIP_WHITESPACE_MINIFY_IGNORED_PATHS is a Python ListChange NBSP Mangle Character :This module first replaces the &nbsp; character from html with a character.
For example &nbsp; becomes ‘অ’ ( I picked ‘অ’ because its a foreign character and not many sites use the character like this ‘অ’ ).
If for some reason this character is causing problem in your HTML. You can change this from settings.py .To change &nbsp; mangle character:# settings.py# Keep the string as  short as possible.# If you make it long,# the python str.replace() method will use more CPU and RAM thus slowing your site down.STRIP_WHITESPACE_NBSP_MANGLE_CHARACTER='ga'# Note that STRIP_WHITESPACE_NBSP_MANGLE_CHARACTER is a python stringChange Compression Settings :This module can do the work of django.gzip middleware. ( It can also do brotli, zstd 👀 )To change the compression algorithm ( by default using ‘gzip’ because it’s a python stdlib):# settings.pySTRIP_WHITESPACE_COMPRESSION_ALGORITHM="gzip"or"br"or"zstd"or"plain"To use this module with django.gzip middleware ( ordjango_brotlimiddleware ):# settings.pySTRIP_WHITESPACE_COMPRESSION_TYPE='compressed'Contributing :If you like this project add a star.

If you like to add features. Fork this repo and submit a Pull Request. 😛Updates ?? :This repository is freezed. It will automatically install latestpython-strip-whitespaceSpecial Thanks to :alfonsrv: For making merealizethat this module can be used without django gzip middleware
