Flask-CacheBuster is a lightweight Flask extension that adds a hash to the URL query parameters of each static file.

Project description

flask-cachebuster

Flask-CacheBuster is a lightweight http://flask.pocoo.org/ extension that adds a hash to the URL query parameters of each static file. This lets you safely declare your static resources as indefinitely cacheable because they automatically get new URLs when their contents change.

Notes:

Inspired by https://github.com/ChrisTM/Flask-CacheBust, and an updated version of https://github.com/daxlab/Flask-Cache-Buster to work with python 3.+

Installation

Using pip:

pip install flask-cachebuster

Usage

Configuration:

from flask_cachebuster import CacheBuster

config = { 'extensions': ['.js', '.css', '.csv'], 'hash_size': 5 }

cache_buster = CacheBuster(config=config)

cache_buster.init_app(app)

Configuration

Configuration:

* extensions - file extensions to bust
* hash_size - looks something like this `/static/index.css%3Fq3` where [%3Fq3] is the hash size.

The http://flask.pocoo.org/docs/0.12/api/#flask.url_for function will now cache-bust your static files. For example, this template:

<script src="{{ url_for('static', filename='js/main.js') }}"></script>

will render like this:

<script src="/static/js/main.js?%3Fq%3Dc5b5b2fa19"></script>
