moduleerd

Moduleerd is a term encountered in software engineering that describes the process or outcome of designing a software system around modular components that can be developed, tested, deployed, and evolved independently. In practice, moduleerd emphasizes clear separation of concerns, well-defined interfaces, and explicit module boundaries to increase reuse and maintainability.

The term does not have a single formal definition and its exact origin is not uniformly documented. It appears in Dutch-language discussions as a form related to the verb moduleeren, and has shown up in online forums, conference notes, and technical blogs since the 2010s. In these contexts, moduleerd is used to describe both the practice of modular design and the resulting modular architectures.

A typical moduleerd approach involves creating modules with stable interfaces, applying dependency management, versioning, and, in some cases, a module registry or metadata catalog. It aligns with established design principles such as separation of concerns, single responsibility, and interface segregation. The concept is adaptable to different architectural styles, including monoliths with modular boundaries, plugin-driven systems, and microservice-inspired decompositions, depending on scale and governance.

Practices associated with moduleerd include contract-first interface design, modular testing strategies (unit and contract tests), and deployment approaches that minimize cross-module coupling, such as feature toggles or staged rollouts. It often relies on domain-driven design to define module boundaries and on tooling for build, deployment, and runtime modularity.

In evaluation, supporters argue that moduleerd improves maintainability, testability, and replaceability, while critics warn of potential coordination overhead and performance costs from inter-module communication. It is frequently discussed alongside modular programming, plugin architectures, and microservice-oriented approaches.
