Devise::JWT::Cookie

devise-jwt-cookie2 is a fork of devise-jwt-cookie, a devise extension based on devise-jwt. It should be used alongside devise-jwt.

Add this line to your application's Gemfile:

gem 'devise-jwt-cookie2', '~> 0.7.0'

And then execute:

$ bundle

First you need to setup up and configure devise and devise-jwt. This gem hooks into devise-jwt to add an httpOnly cookie with the JWT.

You have to update the user model to be able to use the cookie method. For example:

class User < ApplicationRecord
  devise :database_authenticatable,
         :jwt_cookie_authenticatable,
         :jwt_authenticatable, jwt_revocation_strategy: Blacklist
end

This library can be configured by calling jwt_cookie on the devise config object:

Devise.setup do |config|
  config.jwt do |jwt|
    # config for devise-jwt goes here
  end
  config.jwt_cookie do |jwt_cookie|
    # ...
    jwt_cookie.secure = false if Rails.env.development?
  end
end

The name of the cookie. Defaults to access_token.

If a secure cookie should be set, this means the cookie must be sent over a secure connection. Defaults to true.

HttpOnly option on the cookie, if set to true JavaScript running in the browser cannot access the cookie. Defaults to true

The domain the cookie should be issued to. Will be omitted if not set.

Set's the SameSite attribute on the cookie. Defaults to none.

An object that renews the JWT while the cookie strategy authenticates a request. Defaults to nil, which never renews a token.

Set it to Devise::JWT::Cookie::Refresher.new to re-issue a still-valid token once it is past half its lifetime, so an active user's cookie slides forward instead of expiring:

config.jwt_cookie do |jwt_cookie|
  jwt_cookie.refresher = Devise::JWT::Cookie::Refresher.new
end

A refresher responds to call(token, scope, env), where token is the cookie's JWT (nil when the request has none), and returns a new JWT or nil to keep the current one. The strategy authenticates the request with the returned token and the middleware writes it to the cookie, unless the request revokes the token. Subclass Refresher to supply your own rules, such as recovering a session from a separate refresh credential after the JWT has expired, or capping a session's total lifetime. The private issue(user, scope, aud) helper encodes a token and calls the model's on_jwt_dispatch, so revocation strategies such as Allowlist record it.
