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.

Highlighting select features of the Booktracker

The Booktracker app attempts to approximate real-world concerns of web application development. The main goal of the project is to provide a bit of source data that can be coupled with a backend server to provide a realistic API and frontend web application. What we will do now is step through parts of the application and discuss some important challenges and how solutions were developed.

Development environment

The obvious place to start is by developing a working development environment. To determine how to structure the project directory and bring up a working application, I needed to consider what exactly it was that I needed to build. As a reminder, the Booktracker is an application built from the following:

  • A Svelte-based frontend UI
  • A Sanic-based backend Web API
  • A PostgreSQL database
  • A Redis datastore

Let's take a look at how I created a development environment for these services.
