werkzeug.middleware.shared_data.SharedDataMiddleware

A WSGI middleware which provides static content for development environments or simple server setups. Its usage is quite simple:

import os
from werkzeug.middleware.shared_data import SharedDataMiddleware

app = SharedDataMiddleware(app, {
    '/shared': os.path.join(os.path.dirname(__file__), 'shared')
})

The contents of the folder ./shared will now be available on http://example.com/shared/. This is pretty useful during development because a standalone media server is not required. Files can also be mounted on the root folder and still continue to use the application because the shared data middleware forwards all unhandled requests to the application, even if the requests are below one of the shared folders.

If pkg_resources is available you can also tell the middleware to serve files from package data:

app = SharedDataMiddleware(app, {
    '/static': ('myapplication', 'static')
})

This will then serve the static folder in the myapplication Python package.

The optional disallow parameter can be a list of ~fnmatch.fnmatch rules for files that are not accessible from the web. If cache is set to False no caching headers are sent.

Currently the middleware does not support non-ASCII filenames. If the encoding on the file system happens to match the encoding of the URI it may work but this could also be by accident. We strongly suggest using ASCII only file names for static files.

The middleware will guess the mimetype using the Python mimetype module. If it's unable to figure out the charset it will fall back to fallback_mimetype.
