Phrontend

Build Status Code Climate Test Coverage

Framework to build rich UIs.

Phrontend is a flux implementation.

Install

npm install phrontend --save

Dependencies

From npm@3, you must install react and react-router manually. (https://github.com/npm/npm/releases/tag/v3.0.0 - Peer dependencies are no longer implicitly installed).

Optional - phrontend-webpack - a webpack config maker customized for phrontend apps.

Basic Usage

Let's create a simple counter application.

ActionTypes.js

Defining the action types.

export const INCREMENT_COUNTER = 'INCREMENT_COUNTER';
export const DECREMENT_COUNTER = 'DECREMENT_COUNTER';

CounterActionCreator.js

Let's create the action creators for the defined actions.

import {Dispatcher} from 'phrontend';
import {INCREMENT_COUNTER, DECREMENT_COUNTER} from './ActionTypes';

export let increment = step => Dispatcher.dispatch(INCREMENT_COUNTER, step);
export let decrement = step => Dispatcher.dispatch(DECREMENT_COUNTER, step);

CounterStore.js

import {Store} from 'phrontend';
import {INCREMENT_COUNTER, DECREMENT_COUNTER} from './ActionTypes';

const initialState = {
  count: 0
};

class CounterStore extends Store {
  handler(payload) {
    switch(payload.actionType) {
      case INCREMENT_COUNTER:
        // increment the counter to the absolute value of the data sent
        this.set('count', this.get('count') + payload.data);
        // and emit the change event for the subscribers (views) to update themselves
        this.emitChange();
        break;
      case DECREMENT_COUNTER:
        this.set('count', this.get('count') - payload.data);
        this.emitChange();
    }
  }
}

export default new CounterStore(initialState);

CounterComponent.js

import React from 'react';
import CounterStore from './CounterStore';
import {increment, decrement} from './CounterActionCreator';

export default class extends React.Component {
  constructor(...args) {
    super(...args);
    this.handleChange = this.handleChange.bind(this);
    this.handleStepChange = this.handleStepChange.bind(this);
    this.state = {
      step: 1,
      count: 0,
    }
  }
  componentDidMount() {
    // subscribe to the change events published by the store this view
    // wants to listen to
    CounterStore.subscribe(this.handleChange);
  }
  componentWillUnmount() {
    // cleanup - unsubscribe from the store
    CounterStore.unsubscribe(this.handleChange);
  }
  // handle the change emitted by the store
  handleChange() {
    this.setState({
      // .get is synchronous
      count: CounterStore.get('count')
    });
  }
  handleStepChange(e) {
    // this is to maintain the step value
    this.setState({
      step: e.target.value ? parseInt(e.target.value) : 0
    });
  }
  render() {
    return <div>
      Current Value: {this.state.count}
      <div>
        <button style={buttonStyle} onClick={decrement.bind(null, this.state.step)}>-</button>
        <button style={buttonStyle} onClick={increment.bind(null, this.state.step)}>+</button>
      </div>
      <div>Step : <input onChange={this.handleStepChange} value={this.state.step}/></div>
    </div>;
  }
}

App.js

import React from 'react';
import CounterComponent from './CounterComponent';

window.addEventListener('DOMContentLoaded', function() {
    //Append the component to the container
  React.render(<CounterComponent/>, document.getElementById('container'));
});
