daphne 1.0.2

Django ASGI (HTTP/WebSocket) server

Daphne is a HTTP, HTTP2 and WebSocket protocol server for ASGI, and developed to power Django Channels.

It supports automatic negotiation of protocols; there’s no need for URL prefixing to determine WebSocket endpoints versus HTTP endpoints.

Running

Simply point Daphne to your ASGI channel layer instance, and optionally set a bind address and port (defaults to localhost, port 8000):

daphne -b 0.0.0.0 -p 8001 django_project.asgi:channel_layer

If you intend to run daphne behind a proxy server you can use UNIX sockets to communicate between the two:

daphne -u /tmp/daphne.sock django_project.asgi:channel_layer

If daphne is being run inside a process manager such as Circus you might want it to bind to a file descriptor passed down from a parent process. To achieve this you can use the –fd flag:

daphne --fd 5 django_project.asgi:channel_layer

If you want more control over the port/socket bindings you can fall back to using twisted’s endpoint description strings by using the –endpoint (-e) flag, which can be used multiple times. This line would start a SSL server on port 443, assuming that key.pem and crt.pem exist in the current directory (requires pyopenssl to be installed):

daphne -e ssl:443:privateKey=key.pem:certKey=crt.pem django_project.asgi:channel_layer

To see all available command line options run daphne with the -h flag.

Root Path (SCRIPT_NAME)

In order to set the root path for Daphne, which is the equivalent of the WSGI SCRIPT_NAME setting, you have two options:

• Pass a header value Daphne-Root-Path, with the desired root path as a URLencoded ASCII value. This header will not be passed down to applications.

• Set the --root-path commandline option with the desired root path as a URLencoded ASCII value.

The header takes precedence if both are set. As with SCRIPT_ALIAS, the value should start with a slash, but not end with one; for example:

daphne --root-path=/forum django_project.asgi:channel_layer

Dependencies

All Channels projects currently support Python 2.7, 3.4 and 3.5. daphne requires Twisted 16.0 or greater.
