# Cathode
A terminal-style web client for [WeeChat](https://weechat.org/), using the
modern **API relay protocol** (WeeChat ≥ 4.0). No build step. No framework.
Drop three files on a web server and go.
> Inspired by [Glowing Bear](https://github.com/glowing-bear/glowing-bear).
---
## Features
- Real-time IRC via WeeChat's JSON/WebSocket relay API
- Terminal aesthetic — white on black (default) and black on white, togglable
- Buffer list, nicklist, message history, input with command history (↑/↓)
- ANSI colour rendering, URL linkification
- Warns on browser-blocked ports before you try to connect
- Self-signed cert helper (opens relay URL in a new tab to accept the warning)
- Zero dependencies, zero build step — plain HTML/CSS/ES-module JS
---
## Requirements
- **WeeChat ≥ 4.0** with the relay plugin enabled and the **api** protocol configured
- A web server to serve the three static files (nginx, Caddy, Apache, or even
`python3 -m http.server`)
- A domain + TLS cert for production use (certbot/Let's Encrypt recommended)
---
## WeeChat relay setup
```
# Inside WeeChat:
# Load the relay plugin if not already loaded
/plugin load relay
# Set a relay password (required)
/set relay.network.password "your_strong_password_here"
# Create the API relay listener on port 9000
# Do NOT use port 6667/6697 — those are blocked by browsers
/relay add api 9000
# For TLS (recommended for non-localhost):
/relay add tls.api 9000
# Verify it's listening:
/relay listport
```
> **Port note:** Ports 66656669 and 6697 (the traditional IRC port range)
> are blocked by all major browsers. Use any other port — 9000 is a safe
> default.
---
## Installation
### 1. Copy the files
```bash
# Clone or download, then copy to your web root:
cp index.html app.js style.css /var/www/cathode/
# Or serve from the repo directly for development:
python3 -m http.server 8080
```
### 2. Set up a reverse proxy (recommended)
For production you'll want a reverse proxy to handle TLS and serve both the
static files and the WeeChat relay API under the same origin — this avoids
mixed-content issues and makes self-signed certs unnecessary.
See the `proxy/` directory for ready-to-use configs:
| Server | File |
|--------|------|
| Caddy | `proxy/Caddyfile` |
| nginx | `proxy/nginx.conf` |
| Apache | `proxy/apache.conf` |
All three configs follow the same pattern:
- Serve static files at `/`
- Proxy `/api*` to `localhost:9000` (your WeeChat relay port)
- Handle WebSocket upgrade headers
### 3. Open in browser
Navigate to your domain. Enter the WeeChat relay host/port and password.
If you're using the reverse proxy setup, the host is your domain and the
port is 443 — the proxy forwards `/api` internally.
---
## Self-signed certificates
If you can't use Let's Encrypt (no domain, air-gapped, LAN-only), you can
still use TLS with a self-signed cert on the WeeChat relay. The browser will
refuse the WebSocket connection until you accept the cert exception:
1. Enter your host and port in Cathode's connect screen
2. Click the **⚠ CERT** button — this opens `https://host:port/api/version`
in a new tab
3. Accept the browser's security warning in that tab
4. Return to Cathode and click **CONNECT**
The exception is remembered by the browser for subsequent sessions.
---
## LAN / local use (no TLS)
If you're connecting from the same machine or a trusted LAN, you can skip TLS:
- In WeeChat: `/relay add api 9000` (without `tls.`)
- In Cathode: uncheck **USE TLS** before connecting
- Serve Cathode itself over plain HTTP too (or `file://` directly)
Note: `ws://` from an `https://` page is blocked by browsers (mixed content).
Either serve Cathode over plain HTTP as well, or use the reverse proxy approach.

## How it works
Cathode uses WeeChat's **API relay protocol** — a clean JSON-over-WebSocket
protocol introduced in WeeChat 4.0, replacing the old binary `weechat` relay
protocol that Glowing Bear was built on.
On connect, Cathode:
1. Opens a WebSocket to `wss://host:port/api` with the password encoded in
the `Sec-WebSocket-Protocol` header (the only header the browser WebSocket
API allows you to set)
2. Sends a batched request: fetch all buffers with last 200 lines and nicks,
then subscribe to real-time events
3. Listens for push events (`buffer_line_added`, `buffer_opened`,
`nicklist_nick_added`, etc.) and updates the UI accordingly
