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.

Setting up a testable application

Imagine this scenario: inspiration strikes you and you have a great application idea. Your excitement and creative juices are flowing as you start formulating ideas in your head about what to build. Of course, you do not rush straight into building it because you have read all the earlier chapters in this book. You take some time to plan it out, and in a caffeine-induced marathon, you start hacking away. Slowly, you start to see the application take shape and it is working beautifully. Hours go by, maybe it's days or weeks—you are not sure because you are in the zone. Finally, after all that work, you have a minimum viable product (MVP). You deploy it and go for some much-deserved sleep.

The problem is that you never set up testing. Undoubtedly, when you now come online and check out the error-handling system that you set up with advice from the previous section, you notice that it is swamped with errors. Uh oh! Users are doing things...
