RSS Feed Index\n\nThis repo hosts\n\n1. a crawler for news feeds (RSS, Atom, ...)\n2. the current crawling result `index.json` for the [majestic million websites](https://majestic.com/reports/majestic-million) which\nis [CC BY Attribution 3.0 Unported](https://creativecommons.org/licenses/by/3.0/deed.en) licensed.\n3. a Github Pages [site](https://lwindolf.github.io/rss-feed-index/) to test the results\n\n## Feed Catalog Format\n\nThe catalog JSON stored as `index.json` has the following format\n\n    {\n        \"example.com\" : [{\n            \"n\" : \"Example.com feed\",\n            \"u\" : \"https://example.com/feed.xml\",\n            \"t\" : 134,\n            \"f\" : \"rss\",\n            \"ns\" : [ \"syn\", \"wfw\", \"dc\" ],\n            \"d\" : 1757110273\n        }]\n    }\n\nThe meaning of the fields being\n\n| Field | Description                                            |\n|-------|--------------------------------------------------------|\n| \u003ckey\u003e | Domain                                                 |\n| n     | Feed title                                             |\n| i     | Feed description                                       |\n| u     | URL to feed                                            |\n| t     | Average score of characters in item description        |\n| f     | Feed type \"rss\", \"atom\", \"json\"                        |\n| ns    | Namespaces / Features discovered                       |\n| d     | Last update timestamp of the feed                      |\n\nAll of the text fields are to be considered UTF-8 plain text and might need escaping.\n\n## Crawler Usage\n\n    wget https://downloads.majestic.com/majestic_million.csv\n    npm i\n    npm run crawl\n\nFor parallel execution there is a `parallel.sh` script.\n\n## Crawler Ethics\n\n- robots.txt is respected\n- feed discovery only on domain root no traversal\n- minimal traffic\n  - 1 update/check request per feed per month max\n  - almost no retries\n  - no parallel crawling on a domain\n- filtering of domains using Cloudflares family filter (1.1.1.3 resolver) to avoid malware and adult content\n\nEffectivley most sites without a feed should be hit by 2 requests only.\nAll sites having feeds should see 2+nr of feeds (specified by `\u003clink rel=\"alternate\" ...\u003e`) requests.\n\nCrawler user agent is\n\n    Mozilla/5.0 (compatible; rss-feed-index-bot/0.9; +https://github.com/lwindolf/rss-feed-index)\n\n## Website Build\n\nPrepare for deployment run:\n\n    npm i\n    npm run build-www\n\nTest locally with `npx serve www`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flwindolf%2Frss-feed-index","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flwindolf%2Frss-feed-index","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flwindolf%2Frss-feed-index/lists"}
