flask-sass

A small Flask extension that makes it easy to use Sass (SCSS) with your Flask application.

This was forked as we use it in our projects and wanted to make sure a copy was available if the original was ever removed.

The original creator adapted from https://github.com/weapp/flask-coffee2js to perform the same task for sass

Installation

Install with PIP

pip install git+https://github.com/openbridge/flask-sass.git#egg=flask-sass

Usage

You can activate it by calling the sass function with your Flask app as a parameter: Your output dir should be located in the static directory.

  from flaskext.sass import sass
  sass(app, input_dir='assets/scss', output_dir='css')

This will intercept the request for output_dir/*.css and compile the file if it is necesary using the files from input_dir/*.scss.

When you deploy your app you might not want to accept the overhead of checking the modification time of your .scss and .css files on each request. A simple way to avoid this is wrapping the sass call in an if statement:

  if app.debug:
      from flaskext.sass import sass
      sass(app)

If you do this you'll be responsible for rendering the .scss files into .css when you deploy in non-debug mode to your production server.
