Funneler

A simple gem for helping coordinate moving a user through a set of routes. The gem uses a token to keep track of the current place in the funnel. The simplest way to use that token is by including a module into the controller and passing the token in the route. However since the token is simply a string it can easily be kept in session or any other datastore if needed.

Installation

Add this line to your application's Gemfile:

gem 'funneler'

And then execute:

$ bundle

Or install it yourself as:

$ gem install funneler

Usage

  1. Add the gem to your web application. The gem is not dependent upon any particular framework. It's only dependency is the [jwt gem](https://github.com/jwt/ruby-jwt]

  2. Generate a token for a given set of routes, and route your user to the first page:

    funnel = Funneler.build(routes: ['/welcome', '/setup', '/complete'])
    redirect_to funnel.first_page
    
  3. Modify those pages to include the Funneler::ControllerMethods helper for reconstituting a funnel from the given token

  4. Use the helper to determine the next page like this:

    <%= link_to funnel.next_page, "Next" %>
    

Details

The Funneler::Funnel is the core maintaining the state of the flow of pages and building the paths with valid tokens.
