django-template-minifying-loader

Django application, providing simple template loader. It reduces HTML output in templates by stripping out whitespace characters between HTML and django template tags. This is an update of django-template-minifier that works with django 1.10.

Things to note:

• It does not make any fancy compression, to do that use GZip Middleware.
• To compress CSS and JS use django-compressor.

Installation

• via virtualenv - yup we highly recommend it!

pip install django-template-minifying-loader

Basic usage

Modify Your Django project settings's module.

For production (note cached loader):

TEMPLATES = [
  {
      'DIRS': [
          str(APPS_DIR.path('templates')),
      ],
      'OPTIONS': {
          'loaders': [
              'django.template.loaders.cached.Loader',
              'template_minifying_loader.loaders.filesystem.Loader',
              'template_minifying_loader.loaders.app_directories.Loader',
          ],
      },
  },
]

For development (each refresh reloads template):

TEMPLATES = [
  {
      'DIRS': [
          str(APPS_DIR.path('templates')),
      ],
      'OPTIONS': {
          'loaders': [
              'template_minifying_loader.loaders.filesystem.Loader',
              'template_minifying_loader.loaders.app_directories.Loader',
          ],
      },
  },
]

Be happy having less spaces and new lines in Your templates!

Advanced usage:

Using modified settings You can: * turn off stripping spaces between HTML tags

TEMPLATE_MINIFIER_HTML_TAGS = False # default = True

• turn off stripping spaces between Django template tags (s{%, %}s)

TEMPLATE_MINIFIER_TEMPLATE_TAGS = False # default = True

• turn off all stripping

TEMPLATE_MINIFIER = False # default = True

• run Your own strip_function, which preprocess templates

TEMPLATE_MINIFER_STRIP_FUNCTION = 'template_minifier.utils.strip_spaces_in_template'

(There is a typo in variable name, see #2 for details)

• use only in production

if DEBUG:
  TEMPLATE_MINIFIER = False

Known issues:

• Don't use // one line comments in Your inline javascript <script> or .js templates. In some cases, if You are using lot of {% if %} there, it can comment out }; or }, for example:

// comment something - !!it's evil!!
{% if %}
function name(){
}
{% endif %}

Use /* */ instead

/* comment something - it's nice and clean <3! */
{% if %}
function name(){
}
{% endif %}

Or just set TEMPLATE_MINIFIER_TEMPLATE_TAGS = False

To do:

• {% new_line %} template_tag
