Rails Action Deprecation

Gem Version RSpec

Deliver the Deprecation and Sunset HTTP header for your old and trashy endpoints.

When phasing out obsolete or out of date endpoints it is necessary to notify your users. An easy way, in addition to your other communication channels, is to directly mark the responses of your endpoints as deprecated.

This is achieved by the two functions provided by this gem. The (draft) Deprecation HTTP header is to mark an endpoint as deprecated and signal that it will be shut down in the future. The Sunset HTTP header is used to mark an endpoint for deletion. It signifies that the endpoint may be removed without warning after the specified date.

Installation

Add this line to your application's Gemfile:

gem 'rails_action_deprecation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_action_deprecation

Usage

To enable deprecation and sunset in your controller, simply use the provided deprecate_endpoint and sunset_endpoint functions. These register an after_action hook that sets the relevant HTTP headers and outputs a message via ActiveSupport::Deprecation.

Both functions take exactly the same parameters. The first is a DateTime describing the date of deprecation or sunset. By default the deprecation or sunset is set for any action in the controller. To limit this the only: parameter can be used exactly as it is available for the rails controller hooks.

If you want to make more information available to your users, the link: parameter must be specified with a percent encoded URL. This URL will be part of the response's Link HTTP header with the relation deprecation or respectively sunset.

Example with deprecated and/or sunset create and destroy actions:

class ExampleController < ActionController::Base
  deprecate_endpoint DateTime.new(2022, 07, 01, 12, 34, 56), only: [:create]
  deprecate_endpoint DateTime.new(2022, 07, 01, 12, 34, 56), only: [:destroy], link: "https://github.com/Qurasoft"
  sunset_endpoint DateTime.new(2023, 07, 01), only: [:destroy]

  def index
    render json: ['element1', 'element2']
  end

  def show
    render json: 'element1'
  end

  def create
    render json: 'newElement'
  end

  def update
    render json: 'changedElement'
  end

  def destroy
    head :no_content
  end
end
