JWT::Auth

JWT-based authentication middleware for Rails API without Devise

Installation

Add this line to your application's Gemfile:

gem 'jwt-auth'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jwt-auth

Usage

Create an initializer:

JWT::Auth.configure do |config|
  ##
  # Token lifetime
  #
  config.token_lifetime = 24.hours

  ##
  # JWT secret
  #
  config.secret = Rails.application.secrets.secret_key_base
end

Include model methods in your user model:

class User < ApplicationRecord
  include JWT::Auth::Authenticatable
end

Add a token_version field to your user model:

class AddTokenVersionToUser < ActiveRecord::Migration[5.0]
  def change
    add_column :users, :token_version, :integer, :null => false, :default => 1
  end
end

Include controller methods in your ApplicationController:

class ApplicationController < ActionController::API
  include JWT::Auth::Authentication
end

class MyController < ApplicationController
  before_action :authenticate_user
end
