This example demonstrates a single action that sequentially applies three array reducer updates to mutate a shared state. It shows how a combined action named “Multi action update!” chains an array replacement, an index-based removal, and a second index-based replacement to transform an initial array `[5,4,3]` into `[5, 42]`. The code uses a custom `createCombinedAction` helper and the `actions.arrayReducer` API to compose atomic reducers, highlighting a pattern for batching multiple state mutations in a Redux-style store. The source is a JavaScript gist by TheComfyChair.

redux-scc-v1-blog-combined-action

This example demonstrates a Redux add-on that batches multiple state updates into a single combined action, visible in the action history as one entry. The code defines a combined action via `createCombinedAction`, which wraps two separate reducer dispatches—`actions.stringReducer.replace` and `actions.arrayReducer.push`—inside a single dispatch call. The visualization highlights how Redux DevTools would log only the combined action, not the individual sub-updates, simplifying debugging of complex state changes. It uses the Redux library and the custom `createCombinedAction` API to bundle the operations.

redux-scc-v1-blog-double-dispatch

This example demonstrates the Redux state-management pattern for managing and visualizing multiple data updates in a JavaScript application. The code shows two consecutive `store.dispatch()` calls that trigger separate state changes: one replacing a string value and another pushing a number into an array. It highlights how Redux handles action dispatching and state transitions, using the Redux store API alongside action creators defined in the `actions` object. The visualization would typically reflect the updated state after each dispatch, showing the sequential effect of double actions on the rendered data.

redux-scc-v1-blog-example-store

This example demonstrates a Redux store chunk that manages both string and numeric-array state through generated reducers and selectors. It uses the `buildStoreChunk` helper to define a `stringReducer` and `arrayReducer` via `Types.reducer`, with `Types.string()` and `Types.arrayOf(Types.number())` schemas. The store is assembled with `createStore` and `combineReducers` from Redux, while `actions`, `reducers`, and `selectors` are destructured from the chunk configuration. The code shows a programmatic approach to structuring Redux state management without explicit action creators or reducer bodies.

Redux without the sanity checks in a single file. Don't use this, use normal Redux. :-)

This example demonstrates a minimal, single-file implementation of Redux’s core API, including `createStore`, `combineReducers`, `bindActionCreators`, and `applyMiddleware`. It shows how these functions work together to manage state and dispatch actions, with `subscribe` for listener registration and `replaceReducer` for hot-swapping. The code defines the store’s logic directly, using plain JavaScript functions like `mapValues` and `compose` to replicate the original library’s behavior without its validation checks. The listing is a gist by Stroked, intended as a concise educational reference for Redux’s internals.

Redux without the sanity checks in a single file. Don't use this, use normal Redux. :-)

This example presents a single-file implementation of Redux, stripped of its typical validation and sanity checks. It defines core Redux APIs, including `createStore`, `combineReducers`, `bindActionCreators`, `compose`, and `applyMiddleware`, using helper functions like `mapValues` and `pick`. The code demonstrates a minimal store with `dispatch`, `subscribe`, `getState`, and `replaceReducer` methods, initializing state with an `@@redux/INIT` action. It shows a functional, albeit simplified, version of Redux’s state management pattern, intended for educational purposes rather than production use.

React, redux, Expect and Deep Freeze

This example demonstrates a pure function called `testFunction` that takes a state number and an action object, returning an updated number for increment, decrement, or unchanged states. The code uses the Expect library to assert five specific input-output pairs, validating correct logic for both counter operations and an unknown action type. After the assertions, it logs "tests passed!" to the console. The reducer pattern mirrors Redux’s action dispatch, though no UI or visualization is rendered—the focus is solely on unit-testing the state transition logic.

Redux + localStorage

This example shows how to persist a Redux store in the browser’s localStorage by syncing state changes through a custom module. The code defines a reducer that handles `SET` and `REMOVE` actions, calling `serialize` to write the updated Immutable.js collection to localStorage after each mutation. On initialization, `deserialize` reads the stored JSON and hydrates the state via `Immutable.Map`. Access to stored values uses memoized `reselect` selectors, while action creators `set` and `remove` trigger updates. The implementation relies on Redux’s reducer/action pattern and the browser’s `localStorage` API.

using reduce for updating nested object vs destructuring

This example contrasts two JavaScript techniques for updating a nested object in response to user interaction, using a simple bar chart built with D3.js. It shows a `reduce` method that iteratively rebuilds the object and a destructuring approach that spreads the previous state, both updating a count property. The data is a small hardcoded array of items, and clicking a button triggers the update, with the resulting chart rendered as SVG rectangles. The visualization highlights the syntactic and structural differences between the two state-management patterns.
