Overview of this book

Developing an interactive, efficient, and fast enterprise web application requires both the right approach and tooling. If you are a web developer looking for a way to tap the power of React’s reusable UI components and the simplicity of Flask for backend development to develop production-ready, scalable web apps in Python, then this book is for you. Starting with an introduction to React, a JavaScript library for building highly interactive and reusable user interfaces, you’ll progress to data modeling for the web using SQLAlchemy and PostgreSQL, and then get to grips with Restful API development. This book will aid you in identifying your app users and managing access to your web application. You’ll also explore modular architectural design for Flask-based web applications and master error-handling techniques. Before you deploy your web app on AWS, this book will show you how to integrate unit testing best practices to ensure code reliability and functionality, making your apps not only efficient and fast but also robust and dependable. By the end of this book, you’ll have acquired deep knowledge of the Flask and React technology stacks, which will help you undertake web application development with confidence.

Session management

Session management is a critical aspect of web development as it enables a web application to identify and track a user’s actions over a certain period. In Flask web applications, session management is typically implemented on the server side using Flask’s in-built session object or a Flask extension such as Flask-Session; on the frontend React side, you can use React’s localStorage or sessionStorage.

Flask thrives on its simplicity as a framework of choice for Python that makes it easy to build small to enterprise-sized web applications. Flask can manage user sessions using the built-in session object and some of the available Flask extensions contributed by the community members.

A session object is a dictionary-like object that is stored on the server and can be accessed by the client via a secure session cookie. To use a session object, a secret key must be set in the Flask application. This secret key is used to encrypt and sign the...
