Have a look here <a href="https://github.com/cobrateam/django-htmlmin#using-the-html_minify-function" rel="noreferrer">https://github.com/cobrateam/django-htmlmin#using-the-html_minify-function</a>

I realise it is mainly used for django but the example shows how to use this projects code to do what you want with a flask view, i think.

blocks|key|210347|text|找到了一个更好的方法来做这件事。您可以使用此方法缩小所有页面：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|210348|from+flask+import+Flask

Found a better way to do this. You can minify all your pages with this method:

<pre><code>from flask import Flask
from htmlmin.main import minify

app = Flask(__name__)


@app.after_request
def response_minify(response):
 """
 minify html response to decrease site traffic
 """
 if response.content_type == u'text/html; charset=utf-8':
 response.set_data(
 minify(response.get_data(as_text=True))
 )

 return response
 return response
</code></pre>

I use the following decorators

<pre><code>import bs4
import functools
import htmlmin


def prettify(route_function):
 @functools.wraps(route_function)
 def wrapped(*args, **kwargs):
 yielded_html = route_function(*args, **kwargs)
 soup = bs4.BeautifulSoup(yielded_html, 'html.parser')
 return soup.prettify()

 return wrapped

def uglify(route_function):
 @functools.wraps(route_function)
 def wrapped(*args, **kwargs):
 yielded_html = route_function(*args, **kwargs)
 minified_html = htmlmin.minify(yielded_html)
 return minified_html

 return wrapped
</code></pre>

And simply wrapped the default render_template function like so

<pre><code>if app.debug:
 flask.render_template = prettify(flask.render_template)
else:
 flask.render_template = uglify(flask.render_template)
</code></pre>

This has the added benefit of being auto added to the cache, since we don't actually touch app.route

Use the decorator.

<pre><code>from htmlmin.decorator import htmlmin

@htmlmin
def home():

Or you can just use:

<pre><code>re.sub(r'&gt;\s+&lt;', '&gt;&lt;', '&lt;tag&gt; &lt;/tag&gt;') # results '&lt;tag&gt;&lt;/tag&gt;'

To extend the usefulness of the answer from @olly_uk and the comment by @Alexander, it appears that the <a href="https://github.com/cobrateam/django-htmlmin" rel="nofollow">django-htmlmin</a> extension is now designed to be used with frameworks other than Django.

From the docs <a href="https://github.com/cobrateam/django-htmlmin#using-the-html_minify-function" rel="nofollow">here</a>, you can manually use the html_minify function in Flask views, like so:

<pre><code>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)
</code></pre>

Modifying @Bletch answer for the latest version of htmlmin.

<pre><code>from flask import Flask
import htmlmin

app = Flask(__name__)

@app.route('/')
def home():
 rendered_html = render_template('home.html')
 return htmlmin.minify(rendered_html)
</code></pre>

<a href="https://htmlmin.readthedocs.io/en/latest/quickstart.html" rel="nofollow noreferrer">https://htmlmin.readthedocs.io/en/latest/quickstart.html</a>

The minified html will still have some spaces between the tags. If we want to remove that, then <code>remove_empty_space =True</code> attribute needs to be added while the template is rendered.

<pre><code>return htmlmin.minify(rendered_html, remove_empty_space =True)
</code></pre>

<a href="https://htmlmin.readthedocs.io/en/latest/reference.html" rel="nofollow noreferrer">https://htmlmin.readthedocs.io/en/latest/reference.html</a>

Is there a Flask or Jinja2 configuration flag / extension to automatically minify the HTML output after rendering the template?

是否有Flask或Jinja2配置标志/扩展来在呈现模板后自动缩小HTML输出？
