        "description": "# Incremental Module Loader\n\nProposes a injection pattern for your modules. Each module is simply a callable which takes other named modules as arguments. It is very simple with less than 40 statements of code and allows a great deal of flexibility while still removing frequent boilerplate we had to write on each of our projects. \n\nThis module is used by our SpinHub App (https://www.spinhub.ca) which is currently in development. It is the main building block of our module/service based architecture.\n\n## Use-Case 1: Modularize a flask app\n\nYou have an auth service, a database service and an blueprint creator function. How do you hook all of these together while keeping good separation of concerns and allowing injection of mocked services ? Let's see:\n\n```python\n\nfrom incremental_module_loader import IncrementalModuleLoader\n\nfrom flask import request, jsonify\n\nclass RequestParsingModule(object):\n    def get_authorization_header(self):\n        return request.headers.get('Authorization', None)\n\nclass MyAuthModule(object):\n    def __init__(self, config, request_parser):\n        self.url = config['AUTH_URL']\n        self.request_parser = request_parser\n    \n    def get_user_id_from_token(self):\n        header = self.request_parser.get_authorization_header()\n        pass # Extract user id from header token...\n\nclass MyDatabaseModule(object):\n    def __init__(self, config, auth):\n        self.db_uri = config['SQLALCHEMY_DATABASE_URI']\n        self.auth = auth\n\n    def get_user(self):\n        user_id = self.auth.get_user_id_from_token()\n        pass # Retrieve user data from database...\n\n# Note the name of the arguments here:\ndef route_app(app, config, database):\n\n    @app.route('/userinfo')\n    def userinfo():\n        # This triggers the auth verification from the header extracted from the request parser\n        user = database.get_user()\n        return jsonify(user.dump())\n        # ...\n\n\ndef create_app():\n    app = # (...) Standard app creation with config loading\n\n    module_loader = IncrementalModuleLoader()\n\n    # First init the modules with already created objects:\n    module_loader.update(\n        app=app,\n        config=app.config\n    )\n\n    # Then load in order (\"incrementally\")\n    # Make sure to specify a CALLABLE object (function or class)\n    # The module_loader will call the parameter with the modules it is asking as parameters.\n    module_loader.load(request_parser=RequestParsingModule)\n    module_loader.load(auth=MyAuthModule)\n    module_loader.load(database=MyDatabaseModule)\n\n    # Can be loaded anonymously, returns nothing.\n    module_loader.load(route_app)\n\n    # There you have it !\n\n```\n\n# Creators\n\nCreated by Tack Verification, a company dedicated to reducing operational costs related to hardware systems verification. \nhttps://www.tackv.ca",
