LiveReload.cr

This is a LiveReload server implementation in Crystal.

It creates an HTTP server at http://0.0.0.0:35729 that serves the /livereload.js script and handles official-7 protocol via websocket.

Currently, it does not watch the filesystem for changes. You can use bcardiff/crystal-fswatch or petoem/inotify.cr and trigger a LiveReload::Server#send_reload.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     live_reload:
       github: bcardiff/live_reload.cr

2. Run shards install

Usage

require "live_reload"
require "fswatch"

dir = Dir.current
live_reload = LiveReload::Server.new
FSWatch.watch dir do |event|
  live_reload.send_reload(path: event.path, liveCSS: event.path.ends_with?(".css"))
end

puts "Watching changes from #{dir}"
puts "LiveReload on http://#{live_reload.address}"

live_reload.listen
