The URL Title module automatically fetches and displays titles for URLs posted in chat messages. It operates as a broadcast listener — it registers a broadcast filter with the router (matching only messages containing URLs), receives matching messages via NATS, and sends titled responses back through the same messaging pipeline. No explicit command invocation is needed; the module activates automatically whenever someone posts a link. Features link Automatic URL detection — regex-based extraction of http/https URLs from any chat message HTML title extraction — fetches the tag from the target page

YouTube integration — rich metadata (title, publish date, view count, likes, duration) for videos, Shorts, and live streams via the YouTube Data API

In-memory caching — 10-minute TTL cache reduces duplicate fetches for repeated URLs

Platform-aware colorization — IRC responses use mIRC color codes; other platforms receive plain text

Content-type filtering — only processes text/html responses; skips images, PDFs, and other binary content

Configurable rate limiting

Automatic help registration

Usage

Simply post any URL in a channel where the bot is active, and it will automatically respond with the page title. Only the first URL title per message is posted, to avoid spam in messages containing multiple links.

Standard URL:

  Check this out: https://example.com/some-page  Title: Example Domain

YouTube video (with API key configured):

  https://www.youtube.com/watch?v=dQw4w9WgXcQ  Rick Astley - Never Gonna Give You Up | 📅 Oct 28, 2009 | 👁️ 1.5B | 👍 15.0M | ⏱️ 3:33

YouTube Short:

  https://youtube.com/shorts/abc12345678  Some Short Title #[SHORT] | 📅 Jan 1, 2025 | 👁️ 50.0K | 👍 2.1K | ⏱️ 0:15

YouTube Live stream:

  https://youtube.com/live/xyz12345678  Live Stream Title #[LIVE] | 📅 Mar 15, 2026 | 👁️ 12.0K | 👍 800 | ⏱️ 1:45:00

YouTube Integration

When a YOUTUBE_API_KEY is configured, the module queries the YouTube Data API for rich metadata. It detects three URL patterns:

Standard videos: youtube.com/watch?v= — labeled with video metadata
Shorts: youtube.com/shorts/ — labeled with #[SHORT]
Live streams: youtube.com/live/ — labeled with #[LIVE]

Without an API key, YouTube links fall back to standard HTML title fetching.

Caching

The module maintains an in-memory Map with a 10-minute TTL. A cleanup interval runs every 5 minutes to evict expired entries. This reduces duplicate fetches when the same URL is posted multiple times in quick succession.

Content-Type Filtering

The module only processes HTTP responses with a text/html content type. Binary content (images, PDFs, etc.) is skipped entirely, preventing unnecessary processing and potential errors from trying to parse non-HTML responses.

Other defaults:

Setting	Default	Description
HTTP User-Agent	`Mozilla/5.0 (compatible; eevee.bot URL Title Fetcher; +https://eevee.bot)`	Hardcoded in fetch requests
HTTP timeout	10 seconds	Via `AbortSignal.timeout(10000)`
Title max length	200 characters	Truncated with `...` if exceeded
Cache TTL	10 minutes	In-memory, cleaned every 5 minutes
Broadcast TTL	120 seconds	Router broadcast registration TTL

NATS Subjects

Direction	Subject	Purpose
Out	`broadcast.register`	Register URL-filtered broadcast with the router
In	`broadcast.message.`	Receive messages containing URLs
In	`control.registerBroadcasts`	Re-register broadcasts (global)
In	`control.registerBroadcasts.urltitle`	Re-register broadcasts (module-specific)
Out	`chat.message.outgoing.*`	Send titled responses

Configuration

To deploy the urltitle module, add it to your bot’s botModules configuration with moduleName: "urltitle":

 botModules: - name: urltitle spec: size: 1 image: ghcr.io/eeveebot/urltitle:latest pullPolicy: Always metrics: true metricsPort: 8080 ipcConfig: my-eevee-bot moduleName: urltitle envSecret: name: eevee-bot-urltitle-secrets moduleConfig: | enabled: true ratelimit: mode: drop level: user limit: 5 interval: 1m

Environment Variables

Variable	Required	Description
`YOUTUBE_API_KEY`	No	YouTube Data API v3 key. Enables rich metadata for YouTube URLs. Without it, YouTube links fall back to standard HTML title fetching.
