JwtAuthenticable

Researchable's JWT Authenticable gem. This gem provides a standard way of authenticating users using JWT tokens.

Installation

Add this line to your application's Gemfile:

gem 'researchable_jwt-authenticable'

And then execute:

Or install it yourself as:

$ gem researchable_jwt-authenticable

Usage

Simply add the following to your ApplicationController:

class ApplicationController < ActionController::API
  include JwtAuthenticable::Auth

  before_action :authenticate_user!
  before_action :set_profile!

  attr_accessor :current_profile

  # rest of your controller

  private

  # @note authorization_token! will raise an error if the token is invalid, but this is called after
  #   authenticate_user! which will raise the same error. Therefore we don't need to rescue the error here.
  def set_profile!
    uuid = authorization_token!['sub']
    @current_profile = Profile.find_by uuid: uuid
    # If current_profile is nil, it is the first time the user is talking to base-backend. If the token is valid we
    # can simply create a new profile.
    @current_profile ||= Profile.create uuid: uuid
  end
end
