Redux Dynamic Modules

What is it?

redux-dynamic-modules is a library that aims to make Redux Reducers easy to modularize and add/remove dynamically.

Motivation

In large React/Redux applications, oftentimes you will have portions of your state that serve distinct purposes. For example, you might have a reducer and saga that manages LoginState in your application, or another set that manages Todos. These can be split up into a LoginModule and a TodoModule.

Modules provide the following benefits:

They can be easily re-used across the application, or between multiple similar applications.
They can be added/removed from the store dynamically, ex. when a component mounts or when a user performs an action

Features

Group together reducers, middleware, and state into a single, re-usable module.
Add and remove modules from a Redux store at any time.
Use the included <DynamicModuleLoader /> component to automatically add a module when a component is rendered
Extensions provide integration with popular libraries, including redux-saga and redux-observable

Install

Run

npm install redux-dynamic-modules

yarn add redux-dynamic-modules

Usage

Create a module with the following format

export function getUsersModule(): IModule<IUserState> {
  return {
    id: "users",
    reducerMap: {
      users: usersReducer
    },
    sagas: [usersSaga],

    // Actions to fire when this module is added/removed
    // initialActions: [],
    // finalActions: []
  }
}

Create a ModuleStore

import {configureStore, IModuleStore} from "redux-dynamic-modules";
import {getUsersModule} from "./usersModule";

const store: IModuleStore<IState> = configureStore(
  /* initial state */
  {},

  /* redux-saga context */ 
  {},

  getUsersModule(), 
  /* ...any additional modules */
);

Use like a standard Redux store
Use the DynamicModuleLoader React component to add/remove modules when components mount/unmount

<DynamicModuleLoader reduxModules={modules}>
   <div>Hello World!!</div>
</DynamicModuleLoader>

Examples

See the Todo App for a quick of example of the library in practice.
