.build(project_root, client_app_path, server_app_path, elixir_app_path) ⇒ Object

project_root: This is the directory where the canvas_urls.rb file will be written. This file contains all urls and functions for access to the Canvas API from this gem (lms_api). client_app_path: This where all client side Javascript for accessing the Canvas API will be written. server_app_path: This is where all server side Javascript for accessing the Canvas API will be written. Currently, this is generating GraphQL for Javascript
