The starlette-cramjam middleware aims to provide a unique Compression middleware to support Brotli, GZip and Deflate compression algorithms with a minimal requirement.

The middleware will compress responses for any request that includes "br", "gzip" or "deflate" in the Accept-Encoding header.

As for the official Starlette middleware, the one provided by starlette-cramjam will handle both standard and streaming responses.

stralette-cramjam is built on top of pyrus-cramjam an Extremely thin Python bindings to de/compression algorithms in Rust.

Installation

You can install starlette-cramjam from pypi

$ pip install -U pip
$ pip install starlette-cramjam

or install from source:

$ pip install -U pip
$ pip install https://github.com/developmentseed/starlette-cramjam.git

Usage

The following arguments are supported:

  • minimum_size (Integer) - Do not compress responses that are smaller than this minimum size in bytes. Defaults to 500.
  • exclude_path (Set of string) - Do not compress responses in response to specific path requests. Entries have to be valid regex expressions. Defaults to {}.
  • exclude_mediatype (Set of string) - Do not compress responses of specific media type (e.g image/png). Defaults to {}.

Minimal (defaults) example

import uvicorn

from starlette.applications import Starlette
from starlette.responses import PlainTextResponse

from starlette_cramjam.middleware import CompressionMiddleware

# create application
app = Starlette()

# register the CompressionMiddleware
app.add_middleware(CompressionMiddleware)


@app.route("/")
def index(request):
    return PlainTextResponse("Hello World")


if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)

Using options

import uvicorn

from starlette.applications import Starlette
from starlette.responses import PlainTextResponse, Response

from starlette_cramjam.middleware import CompressionMiddleware

# create application
app = Starlette()

# register the CompressionMiddleware
app.add_middleware(
    CompressionMiddleware,
    minimum_size=0,  # should compress everything
    exclude_path={"^/foo$"},  # do not compress response for the `/foo` request
    exclude_mediatype={"image/jpeg"},  # do not compress jpeg
)


@app.route("/")
def index(request):
    return PlainTextResponse("Hello World")

@app.route("/image")
def foo(request):
    return Response(b"This is a fake body", status_code=200, media_type="image/jpeg")

@app.route("/foo")
def foo(request):
    return PlainTextResponse("Do not compress me.")


if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)
