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.

Building the session API

To manage user sessions, we need a session (authentication) API that provides routes to log in and log out (i.e., to create and delete sessions). Login should result in a cookie being set, and logout results in the cookie being deleted. As per the authentication setup, login should require an email and matching password. We’ll add this API via a sessions blueprint containing login, logout, and status functionality.

Creating the blueprint

A blueprint is a collection of route handlers and is useful to associate the related session functionality. It can be created with the following code in backend/src/backend/blueprints/sessions.py:

from quart import Blueprint
blueprint = Blueprint("sessions", __name__)

The blueprint then needs to be registered with the app, by adding the following to backend/src/backend/run.py:

from backend.blueprints.sessions import blueprint as sessions_blueprint
app.register_blueprint(sessions_blueprint)
