You just got a brand new template fron the front-end designer, Everything's going well, Until you realize the amount of time you'll spend manually changing the links in the html templates you until all the static files and assets are properly linked and the file looks exactly like the demo he/she showed you. with Staticfy you can save that time (and some of your hair) by automatically converting the static urls in your template to dynamic url's that wouldn't break if you decide to move your file to another location.
It transforms html links (in this example Flask) from this:
<img src="img/staticfy.jpg" />
To this:
<img src="{{ url_for('static', filename='img/staticfy.jpg') }}" />
and then your web framework's templating language can resolve the tags to the right url.
It's available as a package on PyPi so you can install it with
pip install staticfyThat's all!
Run it straight from the command line with:
staticfy staticfy.html --static-endpoint=static --add-tags='{"img": "data-url"}'--static-endpoint and --add-tags are optional
By default Staticfy writes to stdout but you can specify an output file with -o or --output
staticfy staticfy.html -o new.html
Notice how it preserves the font-awesome css link at the top of the file?, external resources (images, scripts, font-awesome, google-fonts, bootstrap files, disqus e.t.c) which aren't hosted locally with your website won't be transformed. Staticfy also accepts an optional argument --static-endpoint in case you're not using the default static endpoint.
Staticy also preserves the indentation and formatting of any html file given to it, so your html file(s) are still look the same way and are still readablebe just the way they were before you transformed them.
By default staticfy identifies and transforms the following tags:
- img tags with src attributes --
<img src="" /> - link tags with rel attributes --
<link rel="" /> - script tags with src attributes --
<script src="" />
But it's common these days for javascript libraries (for a slider or animation) that have link to images (mostly) or other static resources. you can easily transform those tags by specifying the --add-tags argument and passing in a valid JSON string, an example is this slider from http://www.pixedelic.com/plugins/camera/, you can transform the div tags like this:
staticfy staticfy.html --add-tags='{"div": "data-src"}'Sure enough it gets transformed.
You can exclude certain tags you don't want to be transformed by specifying the --exc-tags parameter, like --add-tags it expects a valid JSON string.
staticfy staticfy.html --exc-tags='{"img": "src"}'Running that on a template should leave the img tags with the src attribute as they were in the original file.
If you need to transform a lot of templates. You can write a oneliner in bash that does that. An example is this:
for i in folder/*.html; do staticfy $i | install -D /dev/stdin staticfy/$i; doneThat takes all the html files in folder, transforms them and outputs them to a directory called staticfy.
When your project gets big, It's necessary to namespace static assets to avoid name collision, you can achieve this by passing a string to the --namespace argument. The string would automatically be prepended to the url. For example in django
staticfy staticfy.html --namespace 'admin'Would convert <img src="img/staticfy.jpg" /> to this <img src="{% url static admin/img/staticfy.jpg %}" />
Staticfy also converts all single quoted html attributes to double quoted attributes. It's very common to see html files with mixed quotes.
<html>
<head>
<link rel='stylesheet' href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.6.3/css/font-awesome.css" />
<img src="/static/images/staticfy.jpg" />
<img data-url='images/staticfy.jpg' />
<link rel="stylesheet" href='css/style.css' />
<script src="/js/script.js"></script>
</head>
</html>You can easily fix all the inconsistencies by running staticfy on that file. There's also little performance gains when you gzip a html file that has consistent use of quotes (either double or single) against an inconsistent one. Don't believe it...Look at this
You can see a reduction from 219 bytes to 204 bytes, of course this difference is very little, but depending on how inconsistent and large your file is, you could save a save a few kilobytes which means faster page load times for your end users.
HTML is a very forgiving, and you're allowed to use single quotes or double quotes. but double quotes are the Unofficial Standard
Staticfy was initially built with flask in mind, but it can also be extended to support other frameworks easily. Out of the box it supports:
- flask
- django and
- laravel
For example to use staticfy with django, specify --framework=django,
You can also set the environment variable STATICFY_FRAMEWORK to any supported framework, so you can avoid using --framework everytime. if you're running linux you can easily do this.
export STATICFY_FRAMEWORK=djangoIf you specify a framework that isn't found, staticfy would cry and gracefully fall back to it's flask roots.
The tests are located in the test.py file and can be run with:
python -m unittest
Staticfy supports both python2 and python3 (python 2.7 >)
Beautiful soup 4
pip3 install bs4
You can use the requirements file pip3 install -r requirements.txt
If you have issues with importing HTML.parser on python 3.5, upgrade beautifulSoup:
pip install --upgrade beautifulsoup4
Pull requests and issues are highly welcome. I'm still looking to support as many web frameworks as possible.
Describe clearly what your PR attempts to fix (if it's a bug) or improve (If it's an existing feature).
If you want to add support for a new web framework, add the required pattern for the framework to the frameworks dictionary in __config__.py, make your tests pass and submit your Pull request.
