watchers

To monitor RSS feeds and GitHub endpoints without duplicates, use a watcher that persists a watermark of seen IDs and only emits genuinely new items to stdout. This prevents duplicate spam during repeated polling.

Watermark-based deduplication for polling JSON APIs stores a bounded set of extracted stable IDs per watcher name. It compares newly fetched items against this persisted state atomically to ensure only unseen items emit output.

Yes, you can run a feed watcher on a cron schedule for silent monitoring. The watcher stays quiet and outputs empty text on no-change, only printing new RSS, JSON, or GitHub items to stdout when updates are found.

Yes, this RSS and GitHub watcher supports arbitrary JSON API endpoints for event monitoring. Scripts fetch remote data from any JSON endpoint, extract stable IDs, and compare them against a bounded stored set to emit new items.

The best way to watch GitHub commits, issues, and releases incrementally is using a watcher with persisted watermark deduplication. It polls GitHub endpoints, tracks bounded ID sets, and atomically updates state to emit only new activity.
