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.

It is a fairly safe assumption that all web APIs require some input from users at some point. Even APIs that are read-only often might allow for filtering, searching, or paginating data. Therefore, to become proficient at building web applications in general, and Sanic applications specifically, you must learn the data tools at your disposal.

In this chapter, we covered a great deal of material. We learned how to pull data from headers, cookies, and the request body. When using headers, form data, query arguments, and file data, we discovered that these objects could operate as regular dictionaries or dictionaries of lists to be both compliant with HTTP standards and also usable for most regular use cases. Additionally, we saw that the request body itself could be sent as a single chunk or in multiple chunks.

However, perhaps the biggest takeaway is that reading data cannot and does not take a single path. As a reminder, Sanic provides the tools to build the most obvious...
