Python Microservices Development – 2nd edition - Second Edition

By: Simon Fraser, Tarek Ziadé

Overview of this book

The small scope and self-contained nature of microservices make them faster, cleaner, and more scalable than code-heavy monolithic applications. However, building microservices architecture that is efficient as well as lightweight into your applications can be challenging due to the complexity of all the interacting pieces. Python Microservices Development, Second Edition will teach you how to overcome these issues and craft applications that are built as small standard units using proven best practices and avoiding common pitfalls. Through hands-on examples, this book will help you to build efficient microservices using Quart, SQLAlchemy, and other modern Python tools In this updated edition, you will learn how to secure connections between services and how to script Nginx using Lua to build web application firewall features such as rate limiting. Python Microservices Development, Second Edition describes how to use containers and AWS to deploy your services. By the end of the book, you’ll have created a complete Python application based on microservices.

ReactJS and Quart

From the perspective of the server, the JavaScript code is a static file, and so serving React apps with Quart is no trouble at all. The HTML page can be rendered with Jinja2, and the transpiled JSX files can be provided as static content alongside it, much like you would do for plain JavaScript files. We can also get the React distribution and serve those files, or rely on a Content Delivery Network (CDN) to provide them.

In many cases a CDN is the better option, as retrieving the files will be faster, and the browser then has the option of recognizing that it has already downloaded these files and can use a cached copy to save time and bandwidth. Let's name our Quart application dashboard, and start off with a simple structure like this:

  • setup.py
  • dashboard/
    • __init__.py
    • app.py
    • templates/
    • index.html
    • static/
    • people.jsx
