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.

Adding a fake SMTP mail server

At the end of the docker-compose.yaml, we add the last service:

mailhog:
    image: mailhog/mailhog:latest
    expose:
      - 1025
      - 8025

The ports used will be 1025 for Django to connect to the SMTP server and 8025 for the web interface via the webmail.localhost domain because Caddy will act as a reverse proxy.

Now that we have added all the containers, it’s time to test whether the containers run and work with each other.
