Hey, you've got [LiveReload](http://www.livereload.com/) in my [Rack](http://rack.rubyforge.org/)! No need for browser extensions anymore! Just plug it in your middleware stack and go! Use this with [guard-livereload](http://github.com/guard/guard-livereload) for maximum fun! ## Using in... ### Rails In `config/initializers/development.rb`: ``` ruby MyApp::Application.configure do config.middleware.insert_before(Rack::Lock, Rack::LiveReload) end ``` ### config.ru/Sinatra ``` ruby require 'rack-livereload' use Rack::LiveReload ``` ## How it works The necessary `script` tag to bring in a vendored copy of [livereload.js](https://github.com/livereload/livereload-js) is injected right before the closing `head` tag in any `text/html` pages that come through. The `script` tag is built in such a way that the `HTTP_HOST` is used as the LiveReload host, so you can connect from external machines (say, to `mycomputer:3000` instead of `localhost:3000`) and as long as the LiveReload port is accessible from the external machine, you'll connect and be LiveReloading away! ## To-do * Specify the `port` * Override the `host` * Change the reload delays As usual, super-alpha!
