Configuration

By default web socket servers are bound to port 5648. The public URL for this server is also defined in the .env configuration file under the key value of PUBLIC_WS_URL.

Due to how events are propagated to users the web socket server also requires a special wss-hmac.secret file to be in the same directory as the required hmac.secret file. This HMAC is what is used to discern server connections from user connections

Data structure

Event messages come serialized in JSON form. They have the structure of:

{
	"type": <event-type>,
	<event-type>: <data-structure>
}

The full list of supported events are as follows:

• new-message
• delete-channel
• create-channel
• update-nick
