gamja

A bare-bones IRC web client.

Usage

Requires an IRC WebSocket server.

First install dependencies:

npm install --production

soju

Add a WebSocket listener to soju, e.g. listen wss://127.0.0.1:8080.

Configure your reverse proxy to serve gamja files and proxy /socket to soju.

webircgateway

Setup webircgateway to serve gamja files:

[fileserving]
enabled = true
webroot = /path/to/gamja

Then connect to webircgateway and append ?server=/webirc/websocket/ to the URL.

nginx

If you use nginx as a reverse HTTP proxy, make sure to bump the default read timeout to a value higher than the IRC server PING interval. Example:

location /socket {
	proxy_pass http://127.0.0.1:8080;
	proxy_read_timeout 600s;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "Upgrade";
	proxy_set_header X-Forwarded-For $remote_addr;
	proxy_set_header X-Forwarded-Proto $scheme;
}

If you are unable to configure the proxy timeout accordingly, you can set the server.ping option in config.json to an interval, in seconds, between which gamja will send opportunistic pings.

Development server

Start your IRC WebSocket server, e.g. on port 8080. Then run:

npm install
npm start

This will start a development HTTP server for gamja. Connect to it and append ?server=ws://localhost:8080 to the URL.

Query parameters

gamja settings can be overridden using URL query parameters:

• server: path or URL to the WebSocket server
• nick: nickname
• channels: comma-separated list of channels to join (# needs to be escaped)

Alternatively, the channels can be set with the URL fragment (ie, by just appending the channel name to the gamja URL).

Configuration file

gamja default settings can be set using a config.json file at the root:

{
	// IRC server settings.
	"server": {
		// WebSocket URL to connect to (string).
		"url": "wss://irc.example.org",
		// Channel(s) to auto-join (string or array of strings).
		"autojoin": "#gamja",
		// Interval in seconds to send PING commands (number). Set to 0 to
		// disable. Enabling PINGs can have an impact on client power usage and
		// should only be enabled if necessary.
		"ping": 60
	}
}
