create-reduxreducer creates a reducer from an object. so you can easyly split your reduce functions as individual function for each actionType instead of use switch case for filter them.
You can install it via npm. If you'll use it in a Isomorphic/Universal App i recommend you installing it as production dependency.
$ npm install create-reduxreducer --save
It only takes two arguments: an object with the action types as a key and the reduce function that will handle the actionType and an initial state.
In this example we define an actionHandlers object and it's reduce functions:
import createReduxReducer from 'create-reduxreducer';
import ActionTypes from '../actionTypes';
const actionHandlers = {
[ActionTypes.INPUT_NUMBER]: inputNumber,
[ActionTypes.INPUT_DECIMAL]: inputDecimal,
...
};
function inputNumber(state, action) {
...
}
function inputDecimal(state, action) {
...
}
const myReducer = createReducer(actionHandlers, {});
export { myReducer };Then you can use this reducer as a regular redux reducer and pass it to combineReducers when you configure your store.
If you want to use arrow functions remember to define your actionHandlers object after your arrow functions:
import createReduxReducer from 'create-reduxreducer';
import ActionTypes from '../actionTypes';
const imputNumber = (state, action) => state;
const imputDecimal = (state, action) => state;
const actionHandlers = {
[ActionTypes.INPUT_NUMBER]: inputNumber,
[ActionTypes.INPUT_DECIMAL]: inputDecimal,
...
};
const myReducer = createReducer(actionHandlers, {});You can pass as initial state whatever you want, regular objets or even ImmutableJs objects:
import { Record } from 'immutable';
const DataModel = Record({
id:0,
age: 50,
...
});
export default createReducer(actionHandlers, new DataModel());- [react-base](https://github.com/atSistemas/react-base/ (atSistemas React/Redux Isomorphic Platform)
