To create routes in this Namespace, different classes that inherit from the Resource class are declared along with the respective namespace route decorator. Within the created HelloWorld class we declare the methods it contemplates. In our case, only GET is presented, resulting in a GET method available for the docummented_endpoints/hello_world endpoint. Flask Python is a microframework that will allow you to have a web application running with very few steps and nearly no setup. This framework’s simplicity and strong control over what you want in your application have made it one of the most used web development frameworks.
We’ll present all the endpoints already created with a new structure. The endpoints will have no logic but will allow you to understand the steps involved in their creation. We will use this class type to present different use case scenarios of a Flask application. Let’s convert the code above to be inserted into a blueprint and load into the main application. We expect the user to have some basic knowledge of Python to understand all the presented steps.
REST API with CRUD structure
It would not be difficult for someone to find the endpoint, copy the chargify webhook post, and get access to our signup process. All webhook / apis should have authentication to avoid this. Chargify sends a webhook signature with the webhook POST request which we can check is authentic.

Python API Development Fundamentals: Develop a full-stack web application with Python and Flask Paperback – 22 Nov. 2019
I thought I’d put together some of my thoughts on what a simple, minimal Flask ‘production-ready’ application could look like – a list of a few things I wish I’d have known over the years. If you have suggestions for improvements to the advice in this post, do make sure to get in touch and let me know. This popularity ensures it has a vibrant ecosystem of extensions, documentation and tutorials. You should have enough programming experience with Python or another programming language. You should have knowledge of how to install Python packages and how to run your Python applications.
You might also need an Ingress controller to route the traffic to the app. The single thread process consumes 1 CPU second every second.

- You don’t need to come up with requests and limits for CPU and memory.
- The container containerstack/cpustress is engineered to consume all available CPU, but it has to how many CPUs are currently available (in this case is only 2 –cpu 2).
- You will use a simple cache service which has two endpoints, one to cache the data and another for retrieving it.
- Locust includes a convenient dashboard where you can inspect the traffic generated as well as see the performance of your app in real-time.
You will use a simple cache service which has two endpoints, one to cache the data and another for retrieving it. Please notice that setting limits doesn’t make the container see only the defined amount of memory or CPU. Unlike CPU requests, the limits of one container do not affect the CPU usage of other containers. However, if your application uses two threads, it is twice as fast, and it can complete the work in half of the time. Now that you’re familiar with CPU and memory requests let’s have a look at limits.
