Adds easy cache support to Flask.

This is a fork of the Flask-Cache extension.

Flask-Caching also includes the cache module from werkzeug licensed under a BSD-3 Clause License.


Flask-Caching is available on PyPI and can be installed with:

pip install flask-caching

The Cache Extension can either be initialized directly:

from flask import Flask
from flask_caching import Cache

app = Flask(__name__)
# For more configuration options, check out the documentation
cache = Cache(app, config={'CACHE_TYPE': 'simple'})

Or through the factory method:

cache = Cache(config={'CACHE_TYPE': 'simple'})

app = Flask(__name__)

Compatibility with Flask-Cache

There are no known incompatibilities or breaking changes between the latest Flask-Cache release (version 0.13, April 2014) and the current version of Flask-Caching. Due to the change to the Flask-Caching name and the extension import transition, Python import lines like:

from flask.ext.cache import Cache

will need to be changed to:

from flask_caching import Cache

Python versions

Starting with version 1.8, Flask-Caching dropped Python 2 support. The library is tested against Python 3.5, 3.6, and PyPy 3.5.
