Hey, you've got LiveReload in my Rack! No need for browser extensions anymore! Just plug it in your middleware stack and go!
Use this with guard-livereload for maximum fun!
Using in...
Rails
In config/environments/development.rb:
MyApp::Application.configure do
config.middleware.insert_before(Rack::Lock, Rack::LiveReload)
end
config.ru/Sinatra
require 'rack-livereload'
use Rack::LiveReload
How it works
The necessary script tag to bring in a vendored copy of 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!
