Invoerframework

Invoerframework is a software framework that provides a structured approach to collecting, validating, and transforming user input within applications. It aims to reduce boilerplate code and enforce consistent input handling across components.

Core concepts include input sources such as web forms, APIs, and command-line interfaces; adapters that translate source data into a uniform internal representation; validation rules that enforce constraints; transformation and normalization to typed values; and binding which maps input data to domain models. Robust error handling and localization are also typically supported.

Architecture of an invoerframework usually comprises input adapters, a validation layer, a transformation pipeline, a binding layer, and an orchestration or controller component. Configurability, extension points, and testing utilities are often provided to accommodate different project requirements.

Common features include declarative input schemas, custom validators, and structured error reporting. Localization and accessibility considerations are supported, along with asynchronous validation in some implementations. A pluggable plugin system enables new input sources, and testing utilities facilitate unit and integration tests.

Usage scenarios cover web applications for form processing, API endpoints, and command-line tools. The framework helps maintain consistency and testability by centralizing input handling. Typical workflows involve defining an input schema, registering adapters, and running the pipeline to produce a validated model ready for business logic.

History and terminology: the term “invoer” is Dutch for input, and invoerframework describes input-handling frameworks in multilingual contexts. It is not tied to a single vendor and has parallels with data-validation frameworks, form frameworks, and ingestion pipelines.
