Flask html response minifier

Last update: Dec 07, 2022

Overview

Flask-HTMLmin

Minify flask text/html mime type responses. Just add MINIFY_HTML = True to your deployment config to minify HTML and text responses of your flask application.

Installation

To install Flask-HTMLmin, simply use pip:

pip install Flask-HTMLmin

Or use pipenv:

pipenv install Flask-HTMLmin

Or use poetry:

poetry add Flask-HTMLmin

Or alternatively, you can download the repository and install it manually by doing:

git clone [email protected]:hamidfzm/Flask-HTMLmin.git
cd Flask-HTMLmin
python setup.py install

Example

from flask import Flask, render_template
from flask_htmlmin import HTMLMIN
    
app = Flask(__name__)
app.config['MINIFY_HTML'] = True

htmlmin = HTMLMIN(app)
# or you can use HTMLMIN.init_app(app)
# pass additional parameters to htmlmin
# HTMLMIN(app, **kwargs)
# example:
# htmlmin = HTMLMIN(app, remove_comments=False, remove_empty_space=True, disable_css_min=True)


@app.route('/')
def main():
    # index.html will be minimized !!!
    return render_template('index.html')


@app.route('/exempt')
@htmlmin.exempt
def exempted_route():
    # index.html will be exempted and not blessed by holy htmlmin !!!
    return render_template('index.html')


if __name__ == '__main__':
    app.run()

unexpected call to parse_endtag

Hi. Getting a sporadic error 'unexpected call to parse_endtag". I haven't been able to replicate the issue reliably.

Occurs here in parse.py file in htmlmin. assert rawdata[i:i+2] == "</", "unexpected call to parse_endtag"

However as a suggestion, perhaps a try except AssertionError should be added to the reponse_minify method. This way even if the error does occur, the final webpage is still rendered as the original unminified response is returned.

Stop using pytest-runner

setup_requires and tests_requires are firmly deprecated by setuptools upstream, and pytest-runner similarly, since it makes use of functionality that setuptools would like to remove. Stop setting {setup,test}_requires in setup.py, and remove pytest-runner from Pipfile.

Fixes #29

Can we read htmlmin options from the flask config file?
Hi, thanks for the tool!

What do you think about allowing these settings to be set in the app.config?

default_options = { 'remove_comments': True, 'reduce_empty_attributes': True, 'remove_optional_attribute_quotes': False } default_options.update(kwargs)

As well as the other options for htmlmin from https://htmlmin.readthedocs.io/en/latest/reference.html?

Personally, I'd really like to add the "remove_empty_space". Somehow my output has whitespace between all tags, for example the closing tags on my homepage look like this -

</div> </div> </div> </body> </html>
opened by christopherpickering 2

Example not working

I'm testing the example provided in README:

from flask import Flask, render_template
from flask_htmlmin import HTMLMIN
    
app = Flask(__name__)
app.config['MINIFY_PAGE'] = True

htmlmin = HTMLMIN(app)
# or you can use HTMLMIN.init_app(app)
# pass additional parameters to htmlmin
# HTMLMIN(app, **kwargs)

@app.route('/')
def main():
    # index.html will be minimized !!!
    return render_template('index.html')


@app.route('/exempt')
@htmlmin.exempt
def exempted_route():
    # index.html will be exempted and not blessed by holy htmlmin !!!
    return render_template('index.html')


if __name__ == '__main__':
    app.run()

And this is my templates/index.html

<html>
  <head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8">
  </head>

  <body>
    <div>
      Hello
    </div>
    <div>
      World
    </div>
  </body>
</html>

I'm using python 3.7.2 and there is no minified output.

Example not working

I don't know exactly why, but the example doesn't work in my environment. No minify output.

However your other answer works fine.

disable_css_min argument leads to error in initialization

Using the example I get this:

htmlmin = HTMLMIN(app, remove_comments=False, remove_empty_space=True, disable_css_min=True)

TypeError: unexpected keyword argument 'disable_css_min'

Also, when I install via pip, I get this: Using legacy setup.py install for Flask-HTMLmin, since package 'wheel' is not installed.
