Details

This course introduces you to a breadth of features available in the Molten framework to help you build HTTP APIs. You’ll start with the basics, such as creating a virtual environment, installing Molten and various other libraries, such as Pytest, to test your Molten apps, and create REST API. You’ll then move on to more advanced features, such as connecting your Molten application to an SQLite database, adding middleware into your app and setting this middleware to check request headers for the authorization to invoke requests and how to generate documentation using the OpenAPIHandler.

Result

After completing this course, you’ll be ready to use the Molten Framework to build HTTP APIs.

Molten Framework: Building HTTP APIs

  • This course introduces you to a breadth of features available in the Molten framework to help you build HTTP APIs. You'll begin by creating a virtual environment, installing Molten and various other libraries such as Pytest to test out your Molten apps, and installing Gunicorn to serve your apps.
  • You'll then move on to creating REST APIs using the Molten framework. You'll create a very basic REST API with only one route that maps to a function and the API to process an HTTP GET request. You'll also explore the use of a QueryParam object to handle query parameters passed in an HTTP request.
  • You'll next test your Molten APIs using Pytest by writing some simple tests to ensure an HTTP 200 status code is returned when a correct request is sent to the server and an error code is returned with the response otherwise. You'll also learn how these tests can be executed and how to analyze their outputs.
  • You'll learn about the processing of POST requests, how to ensure the validity of POST data using a Molten Schema instance, different ways to define a schema, and how to use a forward reference. You'll explore the built-in objects available in the Molten framework and how to pass in a plain Python dictionary containing settings for an app. Finally, you'll see how settings can be saved in an external JSON file and then imported into a Molten app and how to load settings defined within a TOML file.

Molten Framework: Advanced Features

  • This course covers the use of features in the Molten framework to make your HTTP APIs meaningful and easy to use and test. You'll begin by connecting your Molten application to a SQLite database, including the creation of a cursor to work with the database. You'll then wire up your app so that all the data sent in using POST requests to a specific route is written out to the database. You'll also define handlers for GET requests for that same data by reading from the database.
  • Next, you'll then look at adding middleware into your app and set this middleware to check request headers for the authorization to invoke requests. You'll also tweak the middleware to distinguish between certain types of requests so that authorization is only required for some of them.
  • You'll also see how you can dynamically generate documentation for your Molten application using the OpenAPIHandler. You'll explore how you can use the OpenAPIUIHandler to produce a Swagger UI, which can be used by developers to test the application and also by users to figure out exactly how to use your APIs.
  • Finally, you'll learn how you can serve images to clients using Molten, including attaching a local file to a Response object and returning it to the client.
