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
Enter fullscreen mode Exit fullscreen mode

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.
