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.

Generating fake articles and comments

After defining the database from the models, we are going to generate random data that we will use to work more comfortably.

from faker import Faker
# Delete all posts and comments
# Create fake object
fake = Faker()
def get_full_name():
    return f"{fake.first_name()} {fake.last_name()}"
# Create 30 posts
for _ in range(30):
    post = Post(
# Create 150 comments
for _ in range(150):
    comment = Comment(
