Summarize RSS

Overview

Fetches an RSS feed, gathers its entries into one text, and summarizes it.

This tutorial does not ship as an importable template. Build it manually by following the steps below. NodeTool has no RSS node, so the fetch is a Code node.

Demo

Workflow Steps

1. Fetch feed (nodetool.code.Code) - Calls fetch(url) on the feed URL and parses the XML with parse from @nodetool-ai/sandbox-xml. Read the entries from feed.rss.channel.item and wrap a single entry with [].concat(x ?? []), because the parser returns one object for a one-item feed. Emit each entry’s title and description as one string.
2. Collect (nodetool.control.Collect) - Gathers the streamed entries into a list.
3. Join (nodetool.code.Code) - Joins the list into one string, because the Summarizer’s text input takes a string.
4. Summarizer (nodetool.agents.Summarizer) - Condenses the text with the language model you select.
