SimpleJWTAuthentication

Authorizes user requests by verifying a JWT against a supplied secret key. Currently only supports using the Authorization header with the value in the format Bearer YOUR_JWT. Can also accept required fields as opts, where the key is the field name (and what it will be assigned as on the connection), and the value is the path (that will be passed in to Kernel.get_in/2) to the field.

Usage

Phoenix Integration

• Inside web/router.ex file, add plug to your pipeline like so:

  defmodule MyApp.Router
    use Phoenix.Router

    pipeline :api do
      plug SimpleJWTAuthentication
    end

    scope "/", MyApp do
      pipe_through :api
      get "/hello", HelloController, :hello
    end
  end

• With required fields

  pipeline :api do
    plug SimpleJWTAuthentication, user_id: ["metadata", "user_id"]
  end
