Python Web Development with Sanic

By: Adam Hopkins

Overview of this book

Today’s developers need something more powerful and customizable when it comes to web app development. They require effective tools to build something unique to meet their specific needs, and not simply glue a bunch of things together built by others. This is where Sanic comes into the picture. Built to be unopinionated and scalable, Sanic is a next-generation Python framework and server tuned for high performance. This Sanic guide starts by helping you understand Sanic’s purpose, significance, and use cases. You’ll learn how to spot different issues when building web applications, and how to choose, create, and adapt the right solution to meet your requirements. As you progress, you’ll understand how to use listeners, middleware, and background tasks to customize your application. The book will also take you through real-world examples, so you will walk away with practical knowledge and not just code snippets. By the end of this web development book, you’ll have gained the knowledge you need to design, build, and deploy high-performance, scalable, and maintainable web applications with the Sanic framework.

Securing your application with TLS

If you are not encrypting traffic to your web application, you are doing something wrong. In order to protect information while it is in transit between the web browser and your application, it is an absolute necessity to add encryption. The international standard for doing that is known as TLS, which is a protocol for how data can be encrypted between two sources. Often, however, it will be referred to as SSL (which stands for Secure Sockets Layer and is an earlier protocol that TLS replaces) or HTTPS (which stands for HTTP Secure and is technically an implementation of TLS, not TLS itself). Since it is not important for us how it works and we only care that it does what it needs to do, we will use these terms somewhat interchangeably. Therefore, it is safe for you to think about TLS and HTTPS as the same thing.

So, what is it? The simple answer is that you request a pair of keys from some reputable source on the internet. Your next step is to...
