Usage

import Feed from '@json-feed-types/1_1'

const feed: Feed = {
  version: 'https://jsonfeed.org/version/1.1',
  title: 'JSON Feed',
  icon: 'https://micro.blog/jsonfeed/avatar.jpg',
  home_page_url: 'https://www.jsonfeed.org/',
  feed_url: 'https://www.jsonfeed.org/feed.json',
  items: [

      title: 'JSON Feed version 1.1',
      content_html:
        '<p>We&rsquo;ve updated the spec to <a href="https://jsonfeed.org/version/1.1">version 1.1</a>. It’s a minor update to JSON Feed, clarifying a few things in the spec and adding a couple new fields such as <code>authors</code> and <code>language</code>.</p>\n\n<p>For version 1.1, we&rsquo;re starting to move to the more specific MIME type <code>application/feed+json</code>. Clients that parse HTML to discover feeds should prefer that MIME type, while still falling back to accepting <code>application/json</code> too.</p>\n\n<p>The <a href="https://jsonfeed.org/code/">code page</a> has also been updated with several new code libraries and apps that support JSON Feed.</p>\n',

Types

Extensions

Publishers can use custom objects in JSON Feeds. Names must start with an _ character followed by a letter. Custom objects can appear anywhere in a feed.

The Feed, Author, Item, Attachment, and Hub types are generic. To define extensions, provide a map:

import Feed from '@json-feed-types/1_1'

type CustomFeed = Feed<{
  feed: {
    _meta: {
      copyright: string
    }
  }
  author: {
    _meta: {
      id: string
    }
  }
  item: {
    _meta: {
      type: 'SHORT_EPISODE' | 'LONG_EPISODE' | 'SPECIAL_EVENT'
    }
  }
  attachment: {
    _image?: {
      dimensions: [width: number, height: number]
    }
  }
  hub: {
    _meta: {
      instructions: string
    }
  }
}>
import { Item } from '@json-feed-types/1_1'

type CustomItem = Item<{
  feed: {
    _meta: {
      copyright: string
    }
  }
  author: {
    _meta: {
      id: string
    }
  }
  item: {
    _meta: {
      type: 'SHORT_EPISODE' | 'LONG_EPISODE' | 'SPECIAL_EVENT'
    }
  }
  attachment: {
    _image?: {
      dimensions: [width: number, height: number]
    }
  }
  hub: {
    _meta: {
      instructions: string
    }
  }
}>

The ExtensionMap type from @json-feed-types/common can be used to define an extension map outside of the generic types:

import { ExtensionMap } from '@json-feed-types/common'

type MyExtensionMap: ExtensionMap = {
  feed: {
    _meta: {
      copyright: string
    }
  }
  author: {
    _meta: {
      id: string
    }
  }
  item: {
    _meta: {
      type: 'SHORT_EPISODE' | 'LONG_EPISODE' | 'SPECIAL_EVENT'
    }
  }
  attachment: {
    _image?: {
      dimensions: [width: number, height: number]
    }
  }
  hub: {
    _meta: {
      instructions: string
    }
  }
}
