Prerequisite (for Web only)

Setup EnableX video calling application for Web

  $ npm install -g http-server
  $ git clone https://github.com/EnableX/One-to-One-Video-Sample-Web-Application
  $ cd One-to-One-Video-Sample-Web-Application

TLS/SSL

• First, you need to make sure that openssl is installed correctly, and you have key.pem and cert.pem files. You can generate them using this command:

  $ openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem
  

• This generates a cert-key pair. Then you need to run the server with -S for enabling SSL and -C for your certificate file.

  $ http-server -S -C cert.pem
  

Install

• Switch out of the One-to-One-Video-Sample-Web-Application directory -

  $ cd ..
  

• Setup this project -

  $ git clone https://github.com/EnableX/push-notification-server.git
  $ cd push-notification-server
  $ npm install
