.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Twiggy is a lightweight and fast \s-1HTTP\s0 server with unique features such
as:
.IP "\s-1PSGI\s0" 4
.IX Item "PSGI"
Can run any \s-1PSGI\s0 applications. Fully supports \fIpsgi.nonblocking\fR and
\&\fIpsgi.streaming\fR interfaces.
.IP "AnyEvent" 4
.IX Item "AnyEvent"
This server uses AnyEvent and runs in a non-blocking event loop, so
it's best to run event-driven web applications that runs I/O bound
jobs or delayed responses such as long-poll, WebSocket or streaming
content (server push).
.Sp
This software used to be called Plack::Server::AnyEvent but was
renamed to Twiggy.
.IP "Fast header parser" 4
.IX Item "Fast header parser"
Uses \s-1XS/C\s0 based \s-1HTTP\s0 header parser for the best performance. (optional,
install the HTTP::Parser::XS module to enable it; see also
Plack::HTTPParser for more information).
.IP "Lightweight and Fast" 4
.IX Item "Lightweight and Fast"
The memory required to run twiggy is 6MB and it can serve more than
4500 req/s with a single process on Perl 5.10 with MacBook Pro 13"
late 2009.
.IP "Superdaemon aware" 4
.IX Item "Superdaemon aware"
Supports Server::Starter for hot deploy and graceful restarts.
.Sp
To use it, instead of the usual:
.Sp
.Vb 1
\&    plackup \-\-server Twiggy \-\-port 8111 app.psgi
.Ve
.Sp
install Server::Starter and use:
.Sp
.Vb 1
\&    start_server \-\-port 8111 \-\- plackup \-\-server Twiggy app.psgi
.Ve
.SH "ENVIRONMENT"
.IX Header "ENVIRONMENT"
The following environment variables are supported.
.IP "\s-1TWIGGY_DEBUG\s0" 4
.IX Item "TWIGGY_DEBUG"
Set to true to enable debug messages from Twiggy.
.SH "LICENSE"
.IX Header "LICENSE"
This module is licensed under the same terms as Perl itself.
