A simple, and fast "who is online right now" tracker that uses redis and quantized time slices to keep things fast and lightweight.
Add this line to your application's Gemfile:
gem 'online'
And then execute:
$ bundle
Or install it yourself as:
$ gem install online
# create an online tracker by providing a redis client object
$online = Online::Tracker.new(some_redis_client)
# mark an id (any opaque identifier) online
$online.set_online('user_123')
#interrogate status
$online.online? "user_123" # => true
$online.offline? "user_123" # => false
#by default, a user is marked offline automatically around 3 minutes after they are last seen
# 3 MINUTES PASS
$online.online? "user_123" # => false
$online.offline? "user_123" # => true
# If a user logs out, you can explicitly mark them as offline
$online.set_offline "user_123"
# create an online tracker with a specific timeout value after which a user is considered offline
$online = Online::Tracker.new(some_redis_client, 600) # ten minute timeout
