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!
