Remaster - Redux generator

API

remaster({ name, initialState, actions, createDefault }):

name: Name of your reducer.

initialState: Initial state.

actions: Custom actions. By default, remaster will create an type/action for each field inside initialState. If you have a field called rimColor inside your car reducer, you will get car/SET_RIM_COLOR type.

createDefault: Flag for creating the generic type/action described in actions. The default value is true.

setField(reducerName, fieldName, newValue): Update a single value inside one reducer. Useful for updates where you only modify one prop

reducerName: The name you defined in remaster()

fieldName: Some field from your reducer's initial state, defined in remaster()

newValue: field's new value. If this value is not declared, field will return to it's initial value

reset(reducerName): Reset the selected reducer.

reducerName: The name you defined in remaster()

Usage

Example with ReactJS

Install it:

  yarn add remaster
  // or
  npm install --save remaster

Write your reducer's initial state

// ./redux/reducers/user.js

import remaster from "remaster";

const config = {
  name: "user",
  initialState: {
    age: 50,
    name: "John",
    favoriteFruit: "Mango"
  },
  actions: {
    setNameAndAge: (state, { name }) => ({ ...state, name, age: 123 })
  }
};

const user = remaster(config);

// using this, you can see what are your reducer action types
export const UserTypes = user.TYPES;

export default user.REDUCER;

Combine them

// ./redux/reducers/index.js

import { combineReducers } from "redux";
import userReducer from "./userReducer";

export default combineReducers({
  user: userReducer
});

Create your store

// ./redux/store.js

import reducers from './reducers'
import { createStore } from 'redux'
import { composeWithDevTools } from 'redux-devtools-extension/developmentOnly'

const store = createStore(reducers, composeWithDevTools())

export default store

Wrap your app, just like regular redux

import App from './App'
import React from 'react'
import ReactDOM from 'react-dom'
import Store from '../src/redux/store'
import { Provider } from 'react-redux'

ReactDOM.render(
  <Provider store={Store}>
    <App />
  </Provider>
  , document.getElementById('root'))

Connect your component

import React from 'react';
import { connect } from 'react-redux';

class MyComponent extends React.Component {
  render () {
    const { user } = this.props

    return (
      <div>
        <h3>User</h3>
        <p>Name: {user.name}</p>
      </div>
    )
  }
}

const mapStateToProps = ({ user }) => ({ user })

export default connect(mapStateToProps, null)(MyComponent)

To create a new action, use mapDispatchToProps

import { UserTypes } from "./userReducer";

const mapDispatchToProps = dispatch => {
  return {
    setNameAndAge: payload =>
      dispatch({ type: UserTypes.SET_NAME_AND_AGE, payload })
  };
};

export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);

To update a single field or reset a reducer, import the methods from remaster

import { setField, reset } from "remaster";

export default connect(mapStateToProps, { setField, reset })(MyComponent);
