State management

React Hook Form is a performant, dependency-free form library for React that uses uncontrolled inputs and hooks (register, handleSubmit, formState) to minimize re-renders, with built-in HTML validation and schema resolvers for Zod, Yup, Joi, and others.

Vuex is the formerly-official centralized state management library for Vue.js, providing a single store with predictable, mutation-controlled state and Vue devtools integration for time-travel debugging. It has been superseded by Pinia as Vue's recommended state solution and is now in maintenance mode.

MobX is a signal-based reactive state management library that makes any object observable and automatically tracks which derived computations and UI components depend on which fields, re-running only what's strictly needed. It's framework-agnostic at its core but most commonly paired with React via mobx-react/mobx-react-lite.

Jotai is a minimal, atom-based state management library for React built around tiny composable "atoms" of state that can be derived, combined, and made async. It avoids string keys, integrates with Suspense, and scales from a useState replacement to large TypeScript apps.

ReactiveCocoa provides reactive, declarative extensions to Apple's Cocoa frameworks, built on ReactiveSwift's stream-of-values primitives. It adds UI bindings, control-event signals, Objective-C method interception, and key-value observation wrapped as composable reactive streams for iOS, macOS, watchOS, and tvOS apps.

Relay is Facebook's GraphQL client framework for React that lets components declare their own data requirements via colocated GraphQL fragments, then compiles and batches them into efficient network requests with built-in caching, mutations, optimistic updates, and pagination.

dva is a lightweight React and Redux application framework that wraps redux, redux-saga, and react-router behind a minimal API. It organizes state into Elm-inspired models composed of reducers, effects, and subscriptions, reducing the boilerplate of the traditional Redux ecosystem.

Bloc is a Dart/Flutter state management library implementing the BLoC (Business Logic Component) pattern, separating presentation from business logic via observable streams of events and states. It ships as a family of packages (bloc, flutter_bloc, hydrated_bloc, bloc_test, etc.) covering persistence, testing, concurrency, and linting.

ducks-modular-redux is an open-source JavaScript project in the state management space with 9.6k GitHub stars.

Unstated is a minimalist React state management library that lets you share component-like state across the tree using small Container classes built on React's Context API. It deliberately stays tiny, treating containers as plain classes with a setState-style API rather than acting as a Redux replacement.

A thin React wrapper around the framework-agnostic Final Form library, providing subscription-based form state management where only components depending on changed state re-render. It ships with zero bundle-affecting dependencies and a small footprint.

mobx-state-tree is an open-source TypeScript project in the state management space with 7k GitHub stars. The repository has seen commits within the last year.

TanStack Form is a headless, framework-agnostic form state library for managing complex forms with full TypeScript typing, reactive field hooks, and synchronous/asynchronous validation. You bring your own UI while it handles form state, validation, and workflows.

store is an open-source TypeScript project in the state management space with 3.5k GitHub stars. The repository is actively maintained, with recent commits.

Final Form is a lightweight, framework-agnostic form state management library that uses zero dependencies and opt-in subscriptions to minimize bundle size and re-renders.

A minimal React state management library from RisingStack built on transparent reactive proxies. You wrap state objects with `store()` and components with `view()`, then mutate state with plain JavaScript and components re-render automatically based on which store properties they read.

mobx.dart is an open-source Dart project in the state management space with 2.5k GitHub stars. The repository is actively maintained, with recent commits.

Data Client is a TypeScript data-fetching and normalized caching library for React (and Vue, React Native, Next.js, Expo) that uses declarative, schema-driven resource definitions to bind dynamic data—REST, GraphQL, WebSockets/SSE—to components with one-line hooks and zero manual cache updater functions.

Cerebral is a declarative state and side-effects management library for JavaScript frameworks that provides type-safe, reactive state management across React, Vue, Preact, Inferno, and Angular with a monorepo-based architecture.
