A Blueprint for Production-Ready Web Applications

By: Dr. Philip Jones

Overview of this book

A Blueprint for Production-Ready Web Applications will help you expand upon your coding knowledge and teach you how to create a complete web application. Unlike other guides that focus solely on a singular technology or process, this book shows you how to combine different technologies and processes as needed to meet industry standards. You’ll begin by learning how to set up your development environment, and use Quart and React to create the backend and frontend, respectively. This book then helps you get to grips with managing and validating accounts, structuring relational tables, and creating forms to manage data. As you progress through the chapters, you’ll gain a comprehensive understanding of web application development by creating a to-do app, which can be used as a base for your future projects. Finally, you’ll find out how to deploy and monitor your application, along with discovering advanced concepts such as managing database migrations and adding multifactor authentication. By the end of this web development book, you’ll be able to apply the lessons and industry best practices that you’ve learned to both your personal and work projects, allowing you to further develop your coding portfolio.

Protecting the app

Shortly after you deploy your app in production, users will at best, misuse it, and at worst, attack it. It is therefore worthwhile being defensive from the outset by adding rate limiting and request validation.

Rate limiting limits the rate at which a remote client can make requests to the app. This prevents a user from overloading the app with their requests, thereby preventing other users from using the app.

Validation ensures that the JSON data received (or replied) matches an expected structure. This is helpful as it means an error message is displayed if the JSON data is structurally incorrect. It also mitigates against users sending structures that result in errors or issues in the app.

Adding rate limiting

We’ll use the Quart extension called Quart-Rate-Limiter to enforce rate limits, which is installed by running the following command in the backend directory:

pdm add quart-rate-limiter

We can now activate RateLimiter by adding...
