Http/https signaling server for WebRTC communication

Simply run

npm install
node .\server.js

By default server will run on port 3000 locally. Set environment variable PORT to change it.

Simply click the big button above 😄

Note: This application ships with CORS wide open (*, set below). Anytime CORS_ORIGINS contains * as a value, or if it contains no values, any caller will be able to access your service.

You can set the origins that should be allowed to make cross-origin calls to your service by adding comma seperated values to the CORS_ORIGINS environment variable.

Since this server expects a client to use http long polling to request data that the server doesn't yet have, TCP timeouts are a common occurence. When a timeout occurs, the client is expected to simply recognize that the TCP session has ended due to a timeout, and reconnect.

However, when running this server on azure, the server may send an http 500 response, instead of simply timing out the socket. This is an implementation issue of the azure component that handles node applications. As a result, if you're using this server on azure, you must make your client capable of treating http 500 responses as if the socket has timed out. We do this in our client.

If environment variable APPINSIGHTS_INSTRUMENTATIONKEY is set, logs are available in Application Insights.

Authentication with Azure Active Directory B2C is comming soon.

You can configure this server to use a custom SSL certificate at the platform level (azure, heroku, aws, etc) - to learn how to do so on azure, see this page.
