Platform Method

The Platform method generates feed URLs for known platforms using URL pattern matching. It works without HTTP requests by recognizing URL structures specific to each platform.

How It Works

The Platform method uses handlers for each supported platform:

1. Pattern Matching: Each handler checks if the URL matches its platform (e.g., github.com, youtube.com).
2. URL Generation: The matching handler generates feed URLs based on the URL structure.
3. First Match: The first matching handler wins. Subsequent handlers are skipped.

TIP

Even when feeds are discoverable via HTML <link> tags, the Platform method is useful because it generates feed variants the page does not advertise, like a channel's Shorts feed or a repository's releases feed. Handlers that work from the URL alone need no page content, which helps when you use the method directly and only have a URL.

Hints

Platform handlers attach a hint to each feed URI they generate. Hints provide a machine-readable key and a human-readable label that describe what type of feed the URI represents (e.g., "All uploads", "Videos", "Shorts"). This is useful when a single URL generates multiple feed variants and you need to let users pick the right one, especially for feeds that don't include a descriptive title.

Hints are propagated to the final DiscoverResult objects returned by discoverFeeds. Results from non-platform methods (HTML, headers, guess) do not include hints.

type DiscoverUriHint = {
  key: string    // e.g., 'youtube:all', 'youtube:videos'
  label: string  // e.g., 'All uploads', 'Videos'
}

Basic Usage

import { discoverFeeds } from 'feedscout'

const feeds = await discoverFeeds('https://github.com/feedstand/feedstand', {
  methods: ['platform'],

Configuration

Handler Order

Handlers are checked in order. The first matching handler generates the feeds:

import { discoverFeeds } from 'feedscout'
import { githubHandler, redditHandler, youtubeHandler } from 'feedscout/platform'

const feeds = await discoverFeeds(url, {
  methods: {
    platform: {
      handlers: [youtubeHandler, githubHandler, redditHandler],
    },
  },
})

NOTE

The YouTube handler requires HTML content for @handle, /user/, and /c/ URLs to extract the channel ID. For /channel/UC... URLs, no content is needed.

Creating Custom Handlers

You can create handlers for platforms not included by default.

Handler Interface

A PlatformHandler has two methods:

type PlatformHandler = {
  match: (url: string, content?: string, headers?: Headers) => boolean
  resolve: (
    url: string,
    content?: string,
    headers?: Headers,
    fetchFn?: DiscoverFetchFn,
  ) => Array<DiscoverUriEntry> | Promise<Array<DiscoverUriEntry>>
}

Method	Description
match(url, content?, headers?)	Returns true if this handler should process the URL
resolve(url, content?, headers?, fetchFn?)	Returns an array of DiscoverUriEntry objects for the given page URL

Basic Example

A handler that appends /feed.xml to any URL on a specific domain:

import type { PlatformHandler } from 'feedscout/platform'

const myHandler: PlatformHandler = {
  match: (url) => {
    return new URL(url).hostname === 'example.com'
  },

  resolve: (url) => {
    const { origin } = new URL(url)

    return [{ uri: `${origin}/feed.xml` }]
  },
}

Using URL Patterns

A handler that extracts a username from the URL path:

const profileHandler: PlatformHandler = {
  match: (url) => {
    const { hostname, pathname } = new URL(url)

    return hostname === 'example.com' && pathname.startsWith('/users/')
  },

  resolve: (url) => {
    const { origin, pathname } = new URL(url)
    const match = pathname.match(/^\/users\/([^/]+)/)

    if (match?.[1]) {
      return [{ uri: `${origin}/users/${match[1]}/feed.rss` }]
    }

    return []
  },
}

Using Page Content

When feed URLs can only be found in the HTML, use the content parameter:

const contentHandler: PlatformHandler = {
  match: (url) => new URL(url).hostname === 'example.com',

  resolve: (url, content) => {
    if (!content) {
      return []
    }

    const match = content.match(/data-feed-url="([^"]+)"/)

    return match?.[1] ? [{ uri: match[1] }] : []
  },
}

Combining with Defaults

Add custom handlers alongside the built-in ones:

import { defaultPlatformOptions } from 'feedscout/platform'

const feeds = await discoverFeeds(url, {
  methods: {
    platform: {
      handlers: [myHandler, ...defaultPlatformOptions.handlers],
    },
  },
})
