Twelve-Factor App

The Twelve-Factor App is a methodology for building modern web applications that are scalable, maintainable, and easy to deploy. It emphasizes twelve principles, such as treating codebases as version-controlled, using configuration via environment variables, and managing dependencies explicitly. These practices help apps run consistently across different environments (like development and production), make them easier to scale as user demand grows, and simplify collaboration among teams. Overall, the Twelve-Factor App provides a framework that encourages building robust applications that are less prone to issues and easier to manage over time.
