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.

You go to Stack Overflow or some other website, copy code, paste it, and then move on with your day without thinking twice about it.

This sort of copy/paste mentality is perhaps most prevalent when it comes to database connections. Time for a challenge. Go start up a new Sanic app and connect it to a database. Some developers might approach this challenge by heading to some other codebase (from another project, an article, documentation, or a help website), copying some basic connection functions, changing the credentials, and calling it a day. They may never have put much thought into what it means to connect to a database: if it works, then it must be okay. I know I certainly did that for a long time.

This is not what we are doing here. Instead, we...
