HTML minifier for Python frameworks (not only Django, despite the name).
django-html is an HTML minifier for Python, with full support for HTML 5. It supports Django, Flask and many other Python web frameworks. It also provides a command line tool, that can be used for static websites or deployment scripts.
One of the important points on client side optimization is to minify HTML. With minified HTML code, you reduce the size of the data transferred from the server to the client, which results in faster load times.
To install django-htmlmin, run this on the terminal: :
$ [sudo] pip install django-htmlmin
All you need to do is add two middlewares to your MIDDLEWARE_CLASSES and enable the HTML_MINIFY setting:
MIDDLEWARE_CLASSES = ( # other middleware classes 'htmlmin.middleware.HtmlMinifyMiddleware', 'htmlmin.middleware.MarkRequestMiddleware', )
Note that if you’re using Django’s caching middleware, MarkRequestMiddleware should go after FetchFromCacheMiddleware, and HtmlMinifyMiddleware should go after UpdateCacheMiddleware:
MIDDLEWARE_CLASSES = ( 'django.middleware.cache.UpdateCacheMiddleware', 'htmlmin.middleware.HtmlMinifyMiddleware', # other middleware classes 'django.middleware.cache.FetchFromCacheMiddleware', 'htmlmin.middleware.MarkRequestMiddleware', )
You can optionally specify the HTML_MINIFY setting:
HTML_MINIFY = True
The default value for the HTML_MINIFY setting is not DEBUG. You only need to set it to True if you want to minify your HTML code when DEBUG is enabled.
If you don’t want to minify all views in your app and it’s under a /my_app URL, you can tell the middleware to not minify the response of your views by adding a EXCLUDE_FROM_MINIFYING setting on your settings.py:
EXCLUDE_FROM_MINIFYING = ('^my_app/', '^admin/')
Regex patterns are used for URL exclusion. If you want to exclude all URLs of your app, except a specific view, you can use the decorator @minified_response (check the next section above).
The default behaviour of the middleware is to remove all HTML comments. If you want to keep the comments, set the setting KEEP_COMMENTS_ON_MINIFYING to True:
KEEP_COMMENTS_ON_MINIFYING = True
django-htmlmin also provides a decorator, that you can use only on views you want to minify the response:
from htmlmin.decorators import minified_response @minified_response def home(request): return render_to_response('home.html')
You can use the not_minified_response decorator on views if you want to avoid the minification of any specific response, without using the EXCLUDE_FROM_MINIFYING setting:
from htmlmin.decorators import not_minified_response @not_minified_response def home(request): return render_to_response('home.html')
If you are not working with Django, you can invoke the html_minify function manually:
from htmlmin.minify import html_minify html = '<html> <body>Hello world</body> </html>' minified_html = html_minify(html)
Here is an example with a Flask view:
from flask import Flask from htmlmin.minify import html_minify app = Flask(__name__) @app.route('/') def home(): rendered_html = render_template('home.html') return html_minify(rendered_html)
By default, html_minify() removes all comments. If you want to keep them, you can pass ignore_comments=False:
from htmlmin.minify import html_minify html = '<html> <body>Hello world<!-- comment to keep --></body> </html>' minified_html = html_minify(html, ignore_comments=False)
If you are not even using Python, you can use the pyminify command line tool to minify HTML files:
$ pyminify index.html > index_minified.html
You can also keep the comments, if you want:
$ pyminify --keep-comments index.html > index_minified_with_comments.html
