Install

Install from https://pypi.org/project/Flask-PyMemcache/

pip install Flask-PyMemcache

Initialize

memcache = FlaskPyMemcache(app)

or:

memcache = FlaskPyMemcache()
memcache.init_app(app)

Configuration

Put kwargs for pymemcache to PYMEMCACHE in your Flask configuration.

PYMEMCACHE = {
'server': ('localhost', 11211),
'connect_timeout': 1.0,
'timeout': 0.5,
'no_delay': True,
'key_prefix': b'myapp-',
}

You can use different config key with conf_key keyword:

session = FlaskPyMemcache(conf_key='MEMCACHE_SESSION')
cache = FlaskPyMemcache(conf_key='MEMCACHE_CACHE')
session.init_app(app)
cache.init_app(app)

In addition to normal pymemcache kwargs, Flask-PyMemcache provides following configuration options.

• close_on_teardown -- Close connection to memcached when app teardown.

Use

memcache.client.set('foo', 'bar')
