robitar/MobF

MobF is a reactive state management library for Fable that combines MobX and Elmish patterns to manage application state. It provides core features for immutable state, computed views, and automatic subscription handling, alongside a React integration layer for building observer-based components. The system includes a Fable plugin to transform functions into memoized, reactive UI elements and supports lifecycle management for side effects.

This change introduces the MobF library, a functional reactive state management solution for Fable that combines MobX and Elmish. The release includes the core MobF package, a MobF.React integration, an ObserverComponent Fable plugin, and a test suite. It establishes the foundational API for composing models with immutable states, computed views, and subscriptions, along with standard project configuration files like .editorconfig and .gitignore.

(repo-wide) · high confidence

A new Fable plugin is added to the MobF.React namespace that allows developers to mark functions with the \[ObserverComponent\] attribute. When applied, the plugin transforms the function into a memoized, reactive component using mobx-react-lite's observer, automatically sets the React displayName for better DevTools support, and handles React element keys for record props. This enables seamless integration of MobX state management with Fable/React components.

src/MobF.ObserverPlugin · high confidence

This change introduces the MobF library, a reactive state management solution for F\# applications that integrates with MobX. It provides a \Model\ type supporting record and union state types, automatic subscription handling via \ISubscribable\, and computed properties. The library includes \MobF.React\ for React integration via \mobx-react-lite\, structural computation detection, and extendable computations. It also adds subscription mechanisms like \auto\, \manual\, and \until\ for managing side effects and lifecycle.

src/MobF · high confidence

Added a comprehensive test suite using Fable.Mocha to verify the library's core behaviors. The tests cover model creation and updates, computed property extensions (including primitive, default, and structural metrics), reactive sequences, and auto-subscriptions. Additionally, React-specific tests validate the \observer\ function and the \\<ObserverComponent\>\ plugin, ensuring correct rendering, state updates, and avoidance of unnecessary re-renders.

tests · high confidence

This change introduces the MobF library (version 0.9.5), a reactive state management solution for Fable based on MobX and Elmish. The release adds a new \MobF.React\ project providing React integration via \Fable.React\ 9.4.0 and \mobx-react-lite\, alongside the core \MobF\ library which depends on \mobx\ 6.x. The project has been updated to use Fable 5.0.0 and targets .NET 10.0, with \FSharp.Core\ updated to version 10.0.109. A new \MobF.ObserverPlugin\ is also included to support observer components.
