Route-Rule Pipelines for Extraction and Normalization
RSSHub models each feed as a route: not just a URL path, but a reusable extraction-and-normalization pipeline. This creates clean engineering boundaries for feed production—sites can share parsing strategies while still emitting consistent RSS/Atom structures. Compared with naive full-page scraping, a route layer is naturally cacheable and degradable because each route has explicit inputs, outputs, and failure semantics. The result is a versioned, reviewable, reusable catalog of feed rules.
