redux-injector

library0.1.0jsnpmunverified

A library for dynamically injecting reducers into a Redux store at runtime, enabling lazy loading of reducers and plugin architectures. Version 0.1.0 is the only stable release. Unlike static combineReducers, it uses createInjectStore to accept an uncombined reducer tree and injectReducer to add reducers by path (e.g., 'date.form'). Relies on lodash.set. Release cadence is unknown; last update was years ago. Alternative to static reducer composition or other dynamic Redux solutions like Redux Toolkit's reducer injection examples. Minimal documentation and no recent maintenance, so consider compatibility with modern Redux carefully.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

createInjectStore

✓ import { createInjectStore } from 'redux-injector'

✗ import createInjectStore from 'redux-injector'

This is a named export, not a default export.

injectReducer

✓ import { injectReducer } from 'redux-injector'

✗ const injectReducer = require('redux-injector').injectReducer

CommonJS requires valueless, but ESM named import is preferred.

default import (nonexistent)

✓ import { createInjectStore, injectReducer } from 'redux-injector'

✗ import reduxInjector from 'redux-injector'

No default export exists; using named exports only.

Demonstrates creating a store with createInjectStore and dynamically injecting a reducer using injectReducer with a dot path.

import { createStore, combineReducers } from 'redux'; import { createInjectStore, injectReducer } from 'redux-injector'; // Reducer tree (uncombined) const reducersObject = { counter: (state = 0, action) => { switch (action.type) { case 'INCREMENT': return state + 1; default: return state; } } }; // Create store with inject capability const store = createInjectStore(reducersObject, {}); // Later, inject a new reducer injectReducer('todos', (state = [], action) => { switch (action.type) { case 'ADD_TODO': return [...state, action.payload]; default: return state; } }); store.dispatch({ type: 'INCREMENT' }); store.dispatch({ type: 'ADD_TODO', payload: 'Learn redux-injector' }); console.log(store.getState()); // Output: { counter: 1, todos: ['Learn redux-injector'] }

Debug

Known issues

gotchainjectReducer uses lodash.set so you must ensure path supports dot notation; missing intermediate objects are created automatically.

fix

Be careful with path strings; they follow lodash.set conventions.

affects: >=0.1.0

gotchaDo NOT combine reducers with combineReducers before passing to createInjectStore; pass the plain object tree instead.

fix

Pass an object of reducer functions without combineReducers.

affects: >=0.1.0

deprecatedPackage has not been updated in years; may be incompatible with latest Redux and React versions.

fix

Consider alternatives like Redux Toolkit's dynamic reducer injection or useReducer-based solutions.

affects: >=0.1.0

gotchainjectReducer mutates the store's reducer map and may cause subtle bugs if injected after reducers have been combined.

fix

Inject before any complex state changes or use immutable injection patterns.

affects: >=0.1.0

Errors

Common errors & fixes

Uncaught Error: Reducer "..." returned undefined during initialization.

You passed a combined reducer (result of combineReducers) to createInjectStore instead of a plain object tree.

fix

Pass the uncombined reducer object tree, not the result of combineReducers.

TypeError: Cannot read property 'set' of undefined

Missing lodash dependency (lodash.set not available).

fix

Install lodash: npm install lodash

TypeError: state is not a function

Trying to use injectReducer on a store created with regular createStore, not createInjectStore.

fix

Use createInjectStore from redux-injector instead of createStore.
