This is important because we have different APIs in projects to get data post data but the data somewhere else. As we are planning to eventually release our API in the cloud, we are going to create a Dockerfile to describe what is needed to run the application on a Docker container.
Flask includes many specialized options in addition to the basics covered in this guide. Refer toFlask’s official documentation to learn how to enhance the API created in this tutorial. Create the list endpoint with the code in the example below.
REST and Python: Building APIs
The mega-tutorial got me up and running with flask, and this one is nice as well. I’m going to go back and read the Mega tutorials before I give this a try. I’m looking to build off of what I’m learning and this a a great way to do so. The GET request that retrieves the task list could be expanded in a couple of ways.
