middleman-livereload is an extension for the Middleman static site generator that adds livereloading functionality.


If you're just getting started, install the middleman gem and generate a new project:

gem install middleman
middleman init MY_PROJECT

If you already have a Middleman project: Add gem "middleman-livereload", "~> 3.4.3" to your Gemfile and run bundle install


activate :livereload

The extension supports a number of options that can be given to the activate statement. Eg:

activate :livereload, apply_js_live: false

:host and :port

Livereload's listener host/port, these options get passed to ::Rack::LiveReload middleware. Defaults:'' and '35729'.

:js_host and :js_port

Similar to the :host and :port options, but allow you to specify a different host and port at the frontend Javascript level than at the backend EventMachine level. Useful when running behind a proxy or on a Docker VM. Defaults to :host and :port.

:apply_js_live and :apply_css_live

Whether live reload should attempt to reload javascript / css 'in-place', without complete reload of the page. Both default to true.

⚠️ It does not work with @import'ed CSS files or require'd JS files (because of LiveReload not providing enough information regarding dependencies). On those kind of files, a full page reload will be triggered.


Disable Flash polyfil for browsers that support native WebSockets.


Array of patterns for paths that must be ignored. These files will not be injected with the LiveReload script.

String#match is used for ignoring, so you can use any valid Ruby regular expression in this array.


CSS file to reload when detecting @imported partial was modified. Default stylesheets/all.css).
To opt out set livereload_css_target: nil.


Regexp matching filenames that should trigger reload of :livereload_css_target when changed. Default:'_.*\.css').

:wss_certificate and :wss_private_key

Support secure sockets (WSS) by passing TLS certificate & private key, for example if you're using middleman server --https in development.
