Building SPAs with Django and HTML Over the Wire

By: Andros Fenollosa

Overview of this book

The HTML over WebSockets approach simplifies single-page application (SPA) development and lets you bypass learning a JavaScript rendering framework such as React, Vue, or Angular, moving the logic to Python. This web application development book provides you with all the Django tools you need to simplify your developments with real-time results. You’ll learn state-of-the-art WebSocket techniques to realize real-time applications with minimal reliance on JavaScript. This book will also show you how to create a project with Docker from the ground up, test it, and deploy it on a server. You’ll learn how to create a project, add Docker, and discover development libraries, Django channels, and bidirectional communication, and from then, on you’ll create real projects of all kinds using HTML over WebSockets as a chat app or a blog with real-time comments. In addition, you’ll modernize your development techniques by moving from using an SSR model to creating web pages using WebSockets over HTML. With Django, you’ll be able to create SPAs with professional real-time projects where the logic is in Python. By the end of this Django book, you’ll be able to build real-time applications, as well as gaining a solid understanding of WebSockets with Django.

Part 2: WebSockets in Django
Part 3: HTML over WebSockets
Part 4: Simplifying the frontend with Stimulus


Our journey of learning HTML over the wire with Django comes to an end. We are now able to create SPAs in real time by gathering all the logic in the backend, avoiding duplicating tasks such as validations or HTML structures. We have relieved the frontend of a big responsibility; it now only needs to handle events or animations, thanks to Stimulus controllers and internal automation from datasets.

I would love to tell you that you already know everything you need to know, but the journey continues. The book is just a first push. There is still a lot of work ahead of you: practice, adopt Stimulus in your workflow (or any other similar framework), solve small difficulties typical of any SPA (such as managing when the user clicks on the back button in the history), explore other related protocols such as Server-Side Events, train your colleagues, convince your boss, define your line between backend and frontend (the infinite struggle of any web developer), and even adopt some...
