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.

Background task processing

There comes a time in the development of most applications where the developers or users start to notice the application is feeling a bit slow. Some operations seem to take a long time and it is harming the usability of the rest of the application. It could be computationally expensive, or it could be because of a network operation reaching out to another system.

Let's imagine that you are in this scenario. You have built a great application and an endpoint that allows users to generate a Portable Document Format (PDF) report with the click of a button, showing all kinds of fancy data and graphs. The problem is that to retrieve all the data and then crunch the numbers seems to take 20 seconds. That's an eternity for an HTTP request! After spending time squeezing as much performance out of the report generator as you can, you are finally at the conclusion that it runs as fast as it can. What can you do?

Push it to the background.
