Summary

This chapter has presented the initial requirements to set up a development environment for a single-structured Flask project. It provided the basic elements that are essential to creating a simple Flask prototype, such as the main.py module, routes, database connectivity, repository, services, and configuration files. The nuts and bolts of every procedure in building every aspect of the project describe Flask as a web framework. The many ways to store the configuration settings, the possibility of using custom decorators for database connectivity, and the many options to capture the form data are indicators of Flask being so flexible, extensible, handy, and Pythonic in many ways. The next chapter will focus on the core components and advanced features that Flask can provide in building a more scalable application.
