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.

Running Sanic locally

We finally are at the point where it is time to run Sanic—well, locally, that is. However, we also know we have been doing that all along since Chapter 2, Organizing a Project. The Sanic command-line interface (CLI) is already probably a fairly comfortable and familiar tool, but there are some things that you should know about it. Other frameworks have only development servers. Since we know that Sanic's server is meant for both development and production environments, we need to understand how these environments differ.

How does running Sanic locally differ from production?

The most common configuration change for local production is turning on debug mode. This can be accomplished in three ways, as follows:

  1. It could be enabled directly on the application instance. You would typically see this inside of a factory pattern when Sanic is being run programmatically from a script (as opposed to the CLI). You can directly set the value, as...
