Hi, Developers I have created an open source video calling web app using fine grained reactive Javascript framework SolidJS.

I have used native webrtc for peer-to-peer communication and socketio for signalling remote peer.

Working

An initiator can generate meet code and send to person who want to connect.On the other side person can join the room using the meet code.

Features

  • Toggle your Camera
  • Toggle your Microphone
  • Display connected persons in room
  • Mobile responsive

Technology and Framework

  • SolidJS
  • solid-app-router
  • solid-icons
  • Tailwindcss
  • Webrtc
  • Socketio

SolidJS

I have used many features provided by solidjs to create this web-app. Some of the features are:-

Store

Store provide nested reactivity in solidjs. Store use proxy to track nested reactive data and handles update independently.I have created Store and added all of the properties inside them which will update independently.

const [store, setStore] = createStore({

error: null,

socket: null,

peer: null,

currentStream: null,

currentUser: null,

remoteStream: null,

remoteUser: null,

remoteMuted: false,

remoteWebCam: true,

incommingCall: false,

incommingPayload: null,

muted: false,

webCam: true,

});

Hooks API

In solidjs you can use hook any where in component no restriction like ReactJs.I have created useMeet hook and added all of the store and action there.useMeet handle functionality from userMedia to call end like:-

  • Store creation
  • Socket connection
  • userMedia access request
  • call user
  • answer call
  • handle microphone
  • handle camera
  • handle call end
  • handle user connect and disconnect in realtime usingsocketio

Directives

directive is a syntactic suger over ref. I have created two directive one for video src object handling and another for click outside to close popup and modal.

My video src object handling directive:-

export function getVideoSrc(el, accessor) {

const mediaStream = accessor();

if ("srcObject" in el) {

el.srcObject = mediaStream;

} else {

el.src = URL.createObjectURL(mediaStream);

}

}

el contrains dom element and accessor is a function which will return data whatever i have sent from directive in component

In componnet i have used video directive like this:-

<video

autoPlay

controls={false}

playsInline

use:getVideoSrc={stream}

></video>

after use: getVideoSrc is a function which provide two argument element and accessor. stream i have sent inside directive is accessible by calling accessor function.

onMount

I have create socket connection and handle userMedia access permission inside onMount. This will run after component render.An in solid js component render only once.

onCleanup

I have disconnect socket inside onCleanup. This run when our component unmount.

Incomming features

  • multiple person
  • screen sharing
  • switch between multiple camera and microphone
  • etc...
