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 5: Building Response Handlers

Up until this point, our applications have largely been reactive. We have worked on different parts of web applications to learn how to manage the incoming HTTP request. If we imagine the HTTP request/response cycle as a conversation, so far, we have been only listening. Our applications have been built to hear what the incoming client has to say.

Now, it is our turn to talk. In this chapter, we will begin to explore different facets of the HTTP response. Just as we began our learning of the HTTP request by looking at a raw request object, we will look at the raw response. It looks nearly identical and, by now, should be familiar. We will go on to explore some of the powerful tools that Sanic has to offer. Of course, there are mechanisms for JSON and HTML responses, which are probably the most popular types of content to be delivered on the web today. However, Sanic has an advantage by being an async framework: it is super easy to implement...
