Sinatra Extension: XSendFile

sinatra-xsendfile extension provides x_send_file helper method for sending files faster

XSendFile

• in lighttpd;
• in apache;
• in nginx.

Installation

If you use bundler, simply specify sinatra-xsendfile as a dependency in a Gemfile in your project's root:

gem 'sinatra-xsendfile'

and run bundle install.

Otherwise install the gem as usual:

[sudo] gem install sinatra-xsendfile

Example

require 'rubygems'
require 'sinatra'
require 'sinatra/xsendfile'

configure :production do
  Sinatra::Xsendfile.replace_send_file! # replace Sinatra's send_file with x_send_file
  set :xsf_header, 'X-Accel-Redirect' # set x_send_file header (default: X-SendFile)
end

get '/' do
  x_send_file(__FILE__)
end

get '/lighttpd' do
  x_send_file(__FILE__, :header => 'X-LIGHTTPD-send-file') # custom header
end

get '/sendfile' do
  send_file(__FILE__) # will work as x_send_file in production (see configure block)
end

Note that if your application subclasses Sinatra::Base (modular app), you have to register the extension in your subclass:

helpers Sinatra::Xsendfile
