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.

Leveraging signals for intra-worker communication

In general, Sanic tries to make it possible for developers to extend its capabilities to create custom solutions. This is the reason that when interfacing with Sanic, there are several options to inject custom classes to overtake, change, or otherwise extend its functionality. For example, did you know that you could swap out its HTTP protocol to essentially turn Sanic into a File Transfer Protocol (FTP) server (or any other Transmission Control Protocol (TCP)-based protocol)? Or, maybe you want to extend the router capabilities?

These sorts of customizations are rather advanced. We will not cover them in this book since for most use cases, it is the equivalent of hanging a picture nail on your wall with a sledgehammer.

The Sanic team introduced signals as a method to extend the functionality of the platform in a more user-friendly format. Very intentionally, setting up a signal handler looks and feels like a route handler, as...
