Demo

Live Demo: https://chat.gise.at

The characters after the hashtag define the room, if no hashtag is selected, the create room dialog is displayed.

Therefore simply forward the current URL to invite others.

Installation

This video chat is made to install it on an own webserver.
The webserver need no server-side programming language, only a free firebase project is required.

Prerequisites

• Local development environment
  • Git
  • Node.js
  • npm
• Server
  • nginx or apache

Configuration

Load code and dependencies in your local development environment:

git clone https://github.com/vgiselbrecht/chat.git chat
cd chat
npm install
cp src/config.tmp.json src/config.json

For signaling you need a free Firebase Project with anonymous authentication and realtime database.

Copy the firebase configuration to the src/config.json file in exchangeServices/firebase.

}

Additional STUN / TURN Server can also be added in communication/webrtc/iceServers. To use this video chat behind some Firewalls and NATs, you need a TURN server.

Deploy video chat for development

grunt deploy

Add content from dist directory to the document root of your local webserver.

Deploy video chat for production

grunt deploy --target=production
