React Dialpad

React Dialpad provides you a simple UI independent of communication platform to create calls and handle incoming calls.

Demo using Peer.js

Open demo on two browser windows to see peer-to-peer behaviour.

Install

npm i react-dialpad

Features

Component interaction is achieved in two ways:

- Prop of `onActionInvoked` in order to listen actions invoked by user via UI buttons
- Component methods in order to update component

Props

onActionInvoked(action, data)

Called when an action is invoked by the user by pressing buttons

Params:

• action: One of the following actions
  • CALL_STARTED: Invoked when Call button is pressed
  • CALL_ENDED: Invoked when the Call End button pressed
  • CALL_REPLIED: Invoked when the Call Reply button pressed
  • CALL_REJECTED: Invoked when the Call Reject button pressed
• data: Data related to action. e.g. called number for CALL_STARTED action

onStateChanged(state)

Called when any state change has occured. Just for loggin purpose

States:

• DEFAULT:
• CALLING:
• RINGING:
• ON_CALL:
• INCOMING_CALL:
• REPLYING:
• REJECTING:
• ENDING

Methods

Methods can be accessed using Refs

setRinging()

• Navigates to RINGING state.

setOnCall()

• Navigates to ON_CALL state.

endCall()

• Resets to DEFAULT state.

setIncomingCall(contact)

• Navigates to INCOMING_CALL state. contact: { name, number }

Example Usage

import React from 'react';
import Peer from 'peerjs';

import ReactDialpad from 'react-dialpad';

class App extends React.Component {
	constructor() {
		super();
		this.state = {
			number: '',

		this.onActionInvoked = this.onActionInvoked.bind(this);
		this.onStateChanged = this.onStateChanged.bind(this);
		this.onCallStarted = this.onCallStarted.bind(this);
		this.onCallEnded = this.onCallEnded.bind(this);
		this.onCallReplied = this.onCallReplied.bind(this);
		this.onCallRejected = this.onCallRejected.bind(this);
	}

	componentDidMount() {

	}

	}

	onStateChanged(state) {
		console.log('to state', state);
	}

	}

	onCallEnded() {

		} else {
			this.dialpad.endCall();
		}
	}

	onCallReplied() {
		this.getUserMedia().then((stream) => {
			this.call.answer(stream); // Answer the call with an A/V stream.
			this.registerCallEvents(this.call);
		}).catch((err) => {
			console.log('Failed to get local stream', err);
		});
	}

	onCallRejected() {
		if (this.call.open) {
			this.call.close();
		} else {
			this.dialpad.endCall();
		}
	}

	render() {
		const style = {
			margin: '0 30px',
			float: 'left',
		};

		return (
			<div className="app">
				<div style={style}>Your number: {this.state.number}</div>
				<ReactDialpad
					style={style}
					ref={dialpad => (this.dialpad = dialpad)}
