A simple IRC web client.



Requires an IRC WebSocket server.

First install dependencies:

npm install --production

Then configure an HTTP server to serve the gamja files. Below are some server-specific instructions.


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

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


Setup webircgateway to serve gamja files:

enabled = true
webroot = /path/to/gamja

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


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 / {
	root /path/to/gamja;

location /socket {
	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, or if your IRC server doesn't send PINGs, you can set the server.ping option in config.json (see below).

#Development server

If you don't have an IRC WebSocket server at hand, gamja's development server can be used. For instance, to run gamja on Libera Chat:

npm install --include=dev
npm start -- irc.libera.chat

See npm start -- -h for a list of options.

#Production build

Optionally, Parcel can be used to build a minified version of gamja.

npm install --include=dev
npm run build

#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)
  • open: IRC URL to open
  • debug: if set to 1, debug mode is enabled

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 or path to connect to (string). Defaults to "/socket".
		"url": "wss://irc.example.org",
		// Channel(s) to auto-join (string or array of strings).
		"autojoin": "#gamja",
		// Controls how the password UI is presented to the user. Set to
		// "mandatory" to require a password, "optional" to accept one but not
		// require it, "disabled" to never ask for a password, "external" to
		// use SASL EXTERNAL, "oauth2" to use SASL OAUTHBEARER. Defaults to
		// "optional".
		"auth": "optional",
		// Default nickname (string). If it contains a "*" character, it will
		// be replaced with a random string.
		"nick": "asdf",
		// Don't display the login UI, immediately connect to the server
		// (boolean).
		"autoconnect": true,
		// 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
	// OAuth 2.0 settings.
	"oauth2": {
		// OAuth 2.0 server URL (string). The server must support OAuth 2.0
		// Authorization Server Metadata (RFC 8414) or OpenID Connect
		// Discovery.
		"url": "https://auth.example.org",
		// OAuth 2.0 client ID (string).
		"client_id": "asdf",
		// OAuth 2.0 client secret (string).
		"client_secret": "ghjk",
		// OAuth 2.0 scope (string).
		"scope": "profile"
