What it is

Redux is a JavaScript library that implements a centralized, predictable state management pattern using a unidirectional data flow model (dispatch action → reducer updates store → subscribers notified). The core library is tiny (2kB including dependencies) and provides createStore, combineReducers, applyMiddleware, and bindActionCreators as the foundation for managing application state in a way that enables time-travel debugging and testability. Single-package monolithic library (not a monorepo). Source tree is organized by concern: src/ contains core functions (createStore.ts, applyMiddleware.ts, combineReducers.ts, compose.ts, bindActionCreators.ts), type definitions…

Start here

• src/createStore.ts: Core entry point; implements the Store interface, dispatch mechanism, subscription system, and reducer…
• src/applyMiddleware.ts: Implements middleware composition pattern that wraps dispatch to enable async actions, logging, side…
• src/combineReducers.ts: Handles state tree composition by merging multiple reducer functions into one, enabling modular reducer…
• src/types/: Type definitions for Actions, Middleware, Reducers, Store—critical for TypeScript integration and API documentation.
• src/utils/isPlainObject.ts: Validation utility used throughout to enforce serializable plain-object constraints on state…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository and install dependencies: git clone https://github.com/reduxjs/redux.git && cd redux && yarn install (yarn is the package manager, as evidenced by yarn.lock in the file list). Run tests to verify…

Daily commands:

This is a library, not an application. To verify it works: yarn test (runs Vitest in single-run mode with type checking). For continuous development: yarn test:watch (watches file changes). For coverage: `yarn test:…

…shortened for this brief.

Key cautions & unknowns

• Scorecard: default branch unprotected (0/10)
• No non-obvious gotchas are evident from the data. The library is intentionally minimal. One convention: TypeScript test config (tsconfig.test.json) must be used for yarn type-tests; ordinary yarn test already…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
