Easy Poller

Very simple helper to poll for changes. Just give it an URL and voila.

Add this line to your application's Gemfile:

gem 'easy_poller'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easy_poller

In application.js, add:

//= require easy_poller

Add a polling container.

<%= easy_poller count_users_path %>

This will create something like this and start polling for changes to the given URL. Container's inner html will be replaced with your endpoint's response.

<div class="easy_poller" data-poll="true" data-interval="3000" data-url="/users/count"></div>

Now make your controller return something useful.

class UsersController < ApplicationController
  def count
    render text: User.count
  end
end

That's it!

Poll every 10 seconds. Default: 3

<%= easy_poller count_users_path, interval: 10_000 %>

Do not start polling automatically. You can later start polling interacting directly with the plugin. Default: true

<%= easy_poller count_users_path, poll: false %>

Add HTML properties to the container

<%= easy_poller count_users_path, id: 'users-count-poller', class: 'user poller' %>

Stop polling

$("#users-count-poller").easyPoller("stop");

Start polling

$("#users-count-poller").easyPoller("start");

Start all pollers

$(".easy_poller").easyPoller("start");

Set options

$("#users-count-poller").easyPoller("options", "loadingMessage", "Please wait...");

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
