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.

Creating a password-protected dashboard

Protecting pages in a web application is essential for maintaining security and privacy. By extension, this can help prevent unauthorized access to sensitive information. In this section, you will be implementing a protected dashboard page in a Flask-React web application.

A dashboard is a user-friendly interface that provides an overview of data and information. The data that’s displayed on a dashboard can come from a variety of sources, such as databases, spreadsheets, and APIs.

Flask backend

The following code demonstrates an implementation that allows an admin user to log in and see a protected dashboard page. We will implement minimalist login and logout endpoints that define login and logout functionality and protect the dashboard endpoint. The application uses the Flask-Session library to store session data in the filesystem:

from flask import Flask, request, jsonify, sessionfrom flask_session import Session
app = Flask...
