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.

Chapter 6: Operating Outside the Response Handler

The basic building block of application development within Sanic is the response handler, which is sometimes known as a route handler. Those terms can be used interchangeably and mean the same thing. It is the function that Sanic runs when a request has been routed to your application to be handled and responded to. This is where business logic and HyperText Transfer Protocol (HTTP) logic combine to allow the developer to dictate how responses should be delivered back to the client. It is the obvious place to start when learning how to build with Sanic.

However, response handlers alone do not provide enough power to create a polished application experience. To build out an application that is polished and professional, we must break outside the handler to see which other tools Sanic has to offer. It is time to think about the HTTP request/response cycle as not being confined to a single function. We will broaden our scope so that...
