Revelize is a multiple-page Ruby on Rails web app that allows users to vote on venues for their plans. The front-end is written without any JavaScript, utilizing embedded Ruby files (ERB) and Rails helper methods. The user authentication is implemented using cookies.
Revelize uses Rails 5 with Postgres in the MVC pattern. It has no JavaScript and so the Rails views are responsible for all of the front-end work. The user authentication implements a sessions controller along with a cookie that's stored in the user's browser to authenticate on refresh.
There are four stages of the application's process. The first is where users create an event and invite friends. The second stage requires users to add potential venues for the event. The third has users vote on which venue is most suitable for their plans and the fourth, after the deadline is up, displays the venues that received the most votes. At any stage in the process a user can switch between the first, second, and third stage. When the time deadline is up, however, a user can no longer create venues, vote, or invite friends and remains fixed at the last stage.
Implementing this without any use of JavaScript state management required the heavy use of cookies to determine which stage in the venue voting process a user is at for each event. When a user logs in and clicks on an event, the browser knows which stage that user is at in the voting process. If the time is up for voting, all users are sent to the results page.
