MVUlike

MVUlike is an open-source software framework designed to support the Model-View-Update pattern for building user interfaces. Inspired by the Elm architecture, it aims to provide a compact, predictable state-management approach for web applications. The project has origins in an international open-source community and is maintained with collaborative contributions.

At its core, MVUlike separates state (Model), an Update function that handles messages to produce a new Model, and a View function that renders the UI from the Model. It enforces immutability and a unidirectional data flow. It includes a commands mechanism for asynchronous work and a subscriptions system for listening to external events. The framework is designed to be lightweight and interoperable with other UI stacks via adapters for React, Vue, or vanilla JavaScript.

Development tooling includes time-travel debugging and hot-reload support. A growing set of example apps, tutorials, and adapters have supported its adoption in small teams and education projects. As with any MVU-based approach, onboarding can be slower for developers accustomed to imperative or component-based paradigms, and the ecosystem remains smaller than more established stacks.

MVUlike is maintained on a public repository with community governance and is released under an open-source license. It emphasizes a unidirectional data flow, explicit state transitions, and a clear separation of concerns.
