Chapter 1, Flask Configurations, helps in understanding the different ways in which Flask can be configured to suit various needs as per the demands of the project. It starts by telling us how to set up our development environment and moves on to the various configuration techniques.

Chapter 2, Templating with Jinja2, covers the basics of Jinja2 templating from the perspective of Flask and explains how to make applications with modular and extensible templates.

Chapter 3, Data Modeling in Flask, deals with one of the most important part of any application, that is, its interaction with the database systems. We will see how Flask can connect to database systems, define models, and query the databases for the retrieval and feeding of data.

Chapter 5, Webforms with WTForms, covers form handling, which is an important part of any web application. As much as the forms are important, their validation holds equal importance, if not more. Presenting this information to the users in an interactive fashion adds a lot of value to the application.

Chapter 9, Internationalization and Localization, expands the scope of Flask applications and covers the basics of how to enable support for multiple languages.

Chapter 10, Debugging, Error Handling, and Testing, moves on from being completely development-oriented to testing our application. With better error handling and tests, the robustness of the application increases manifold and debugging aids in making the lives of developers easy.

Chapter 11, Deployment and Post Deployment, covers the various ways and tools using which the application can be deployed. Then, you will learn about application monitoring, which helps in keeping track of the performance of the application.

Chapter 12, Other Tips and Tricks, is a collection of some handy tricks that range from full-text search to caching. Then finally, we will go asynchronous with certain tasks in Flask applications.
