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!
