Flask Autoversion

Automatically version static file paths. When actively developing a web application, you may experience issues with browsers caching your static content. With this extension you can easily use the function in your templates that will update the query added on to the file path to bust the browser cache.

Installation

Install the extension:

pip install Flask-Autoversion

Set Up

A typical setup:

from flask import Flask, render_template
from flaskext.autoversion import Autoversion

app = Flask(__name__)
app.autoversion = True
Autoversion(app)

@app.route('/')
def hello_world():
    return render_template("home.html")

Setting app.autoversion to True will append a query string with the file last-modified timestamp as the value.
