Kemal JWT Authentication

Drop-in authentication middleware for Kemal, independent of user model. See example.cr for a full example.

TL;DR:

require "kemal"
require "kemal_jwt_auth"
# you can use your existing users collection data-structure.
require "./my_users"

# Your `MyUsers` must include the `KemalJWTAuth::UsersCollection` module
collection = MyUsers.default_config

add_handler KemalJWTAuth::Handler.new users: collection

get "/test" do |context|
  if user = context.current_user?
    "Welcome, #{user}!"
  else
    "no user found"
  end
end

Kemal.run

JavaScript companion
