fresco-static 0.5

Static file handling for fresco

Basic usage

Installation:

pip install fresco-static

# If you want brotli compression enabled
pip install fresco-static[brotli]

Simple configuration:

from fresco import FrescoApp
from fresco_static import serve_directory, serve_file

app = FrescoApp()

# Serve a directory
app.route_all("/static", ALL=serve_directory("path/to/static/files"))

# Serve a single file
app.route("/favicon.ico"", ALL=serve_file("path/to/favicon.ico"))

# Serve a directory that's part of a Python package
app.route_all(
    "/static",
    ALL=serve_package_directory("mypackage", "static/files")
)

Advanced options:

app = FrescoApp()
app.route_all(
    "/static",
    ALL=serve_directory(
        "path/to/static/files",

        # Specify custom headers. These will be set for all files served.
        headers={"cache-control": "max-age 86400"},

        # Compression algorithms to offer, in order of preference
        compression="brotli,gzip"

        # Directory to cache compressed copies of files. The same directory may
        # safely be shared between instances
        cachedir="/tmp/staticfilecache"
    )
)

App-wide usage

These instructions are for creating a single StaticFiles object that serves static requests across the entire application.

Create a fresco app:

app = FrescoApp()

Let’s assume this lives in an application that’s structured like this:

mypackage
├── __init__.rst
├── app.py
├── static
│   └── photo.jpg
└── setup.py

Once you have the app, you can create an instance of StaticFiles:

static = StaticFiles(app)

StaticFiles automatically adds routes for the path /static. Static files will be available under /static/<packagename>/<path> eg /static/mypackage/photo.jpg. You can change these defaults:

static = StaticFiles(app,
                     prefix='/media',
                     route_name='media',
                     cache_max_age=3600)

You can have multiple packages serving files through a single StaticFiles object without fear of conflict.

Now you can start configuring static source directories:

# Mount directory '/www/mysite/htdocs'. The first argument is an arbitrary
# name used to identify this source. You can use whatever string you like.
static.add_directory('site-htdocs', '/site/htdocs', cache_max_age=60)

# Serve files located in a 'subdir' directory within the python package
# 'mypackage'
static.add_package('mypackage', 'subdir', cache_max_age=86400)

The cache_max_age argument specifies for how long (in seconds) browsers and proxies can cache responses. For development you might want to set this to zero, but in production use you should set this to a reasonable value and configure a caching HTTP proxy server. When adding source directories you can omit this argument, and the default (configured when you created the StaticFiles object) will be used instead.

static.pathfor generates URLs for static content. You will probably want to include this in your templating system’s default namespace. How you do that depends on how you’ve integrated the templating system, but it would typically be something like this:

templating.contextprocessor({'static': static.pathfor})

Call this in templates to link to static files, eg:

<!-- Reference a file from the "site-htdocs" source
-->
<img src="{{ static('site-htdocs/photo.jpg') }}" alt="My photo" />

<!-- Reference a file from the "mypackage" source
-->
<img src="{{ static('mypackage/photo.jpg') }}" alt="My photo" />

<!-- Path doesn't begin with a source name — all sources will be
     searched for a matching file
-->
<img src="{{ static('cat-pictures/miaow.gif') }}" alt="My photo" />
