frameworkagnostisch

Framework-agnostic, or frameworkagnostisch in German, describes software designed to operate independently of any single development framework, library, or platform. In practice, it means separating core business logic from framework-specific components and defining stable interfaces or contracts that can be implemented by different frameworks without changing the core code.

Key characteristics include decoupling, defined boundaries, and the use of abstractions. Architectural patterns such as clean architecture, hexagonal (ports-and-adapters), or onion architecture are commonly employed. Developers use interfaces, dependency inversion, and dependency injection to steer control flow away from the framework toward explicit abstractions. Core domain rules, validation, and data handling remain framework-agnostic, while adapters translate between the core logic and a particular framework’s APIs.

Benefits of framework-agnostic design include improved testability, portability, and easier migration to new frameworks. It supports reusability of core logic across projects and simplifies maintenance by isolating framework-specific code in adapters or plugins. It also enables teams to switch technologies with limited impact on business rules.

Trade-offs and challenges involve upfront design overhead, potential boilerplate, and the risk of over-abstraction. For small projects or tight deadlines, the extra layers can slow development, and improper abstractions may add confusion rather than clarity. The approach is most beneficial when long-term flexibility, cross-project reuse, or multi-framework support is a priority.

Related concepts include dependency inversion, clean architecture, hexagonal architecture, and portability. Examples include libraries or services intended for use with multiple web frameworks, or backends designed to be framework-agnostic while providing framework-specific adapters.
