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.

Understanding SQLAlchemy ORM basics

SQLAlchemy offers developers the ability to work entirely in Python code to create, read, update, and delete tables. SQLAlchemy is the Python SQL toolkit and ORM that allows application developers to interact with databases without writing direct SQL statements.

As SQLAlchemy is an ORM library, Python classes are mapped to tables, and the instances of those classes are mapped to table rows in a relational database. You then have a situation where you can use Python object-oriented programming code to perform database SQL create, read, update, and delete (CRUD) operations and other necessary operations in your applications.

The ORM feature of SQLAlchemy gives Python developers the power to harness function calls to generate SQL statements out of the box. With this new way of thinking about databases, developers are able to decouple object models and database schema, leading to a more flexible database structure, elegant SQL statements, and Python...
