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.

Configuring an application

Sanic tries to make some reasonable assumptions out of the box about your application. With this in mind, you can certainly spin up an application, and it should already have some reasonable default settings in place. While this may be acceptable for a simple prototype, as soon as you start to build your application, you will realize that you need to configure it.

And this is where Sanic's configuration system comes into play.

Configuration comes in two main flavors: tweaking the Sanic runtime operation, and declaring a state of global constants to be used across your application. Both types of configuration are important, and both follow the same general principles for applying values.

We will take a closer look at what the configuration object is, how we can access it, and how it can be updated or changed.

What is the Sanic configuration object?

When you create a Sanic application instance, it will create a configuration object. That...
