nuxt-feedme

npm version npm downloads License Nuxt

This module provides extra abilities for implementation RSS feed. It's pretty similar to module-feed, but have support nuxt-content.

If you need fully customized feeds, you can freely choose any feed module (this or the mentioned above). But this module can be more flexible.

Features

  • Configured out of the box for nuxt-content
  • Supports general and specialized hooks for both feed kinds
  • Flexible: use configuration defaults (feed, item), mapping (item) or hooks for customization
  • SSR and SSG support

Configured out of the box for nuxt-content

Default settings are:

{
  feeds: {
    '/feed.atom': { revisit: '6h', type: 'atom1', content: true },
    '/feed.xml': { revisit: '6h', type: 'rss2', content: true },
    '/feed.json': { revisit: '6h', type: 'json1', content: true },
  },
  content: {
    item: {
      templateRoots: [true, 'feedme'],
    },
  },
}

General and specialized hooks

// project-name/server/plugins/feedme.ts
import type { NitroApp } from 'nitropack'

// Nitro hooks can be set only in nitro plugin
export default (nitroApp: NitroApp) => {
  // General hook: feedme:handle:content:item
  // Specialized hook: feedme:handle:content:item[*]
  //
  // When specialized hook set, general also will be called
  nitroApp.hooks.hook('feedme:handle:content:item[/contentDefaults.xml]', async ({ feed: { insert, invoke, parsed } }) => {
    if (parsed.title === 'First item') {
      // Invoke in case if item was created by another callback
      const maybeItemOptions = invoke()

      // Insert replaces current item configuration
      insert({
        ...maybeItemOptions,
        category: [
          ...maybeItemOptions?.category ?? [],
          { name: 'content hook processed' },
        ],
      })
    }
  })

  // Specialized hook for default feed
  nitroApp.hooks.hook('feedme:handle[/feed.xml]', async ({ context: { event }, feed: { create } }) => {
    // Create also replaces current feed
    create({ id: '', title: `Special feed for '${event.path}' route`, copyright: '' })
  })

  // General hook for default feed
  nitroApp.hooks.hook('feedme:handle', async ({ context: { event }, feed: { create, invoke } }) => {
    invoke() ?? create({ id: '', title: `Default feed for '${event.path}' route`, copyright: '' })
  })
}

Mapping configuration

Mapping is used for linking feed item object key to the path in parsed content:

{
  item: {
    mapping: [
      // Third item is optional mapping function
      ['date', 'modified', value => value ? new Date(value) : value],
      // When mapping function result is undefined - next variant applied
      ['date', 'created', value => value ? new Date(value) : value],
      // Until the real one value will be set
      ['date', '', () => new Date()],
      // By default mapping is x => x
      ['link', '_path'],
    ],
    // Create default mappings with indicated roots:
    //   [keyof Item /* such as image, id, link */, root + keyof Item]
    //
    // The true value means use empty root:
    //   ['link', 'link']
    //
    // Where any other key means use this as path to value:
    //  ['link', `{root}.link`]
    //
    // Root can be separate by `.` which allows to deep invoking
    templateRoots: [true, 'feedme'],
  }
}

NOTE: Date value is a special case for feed module, so by default mapping provides the next map for the date field: value => value ? new Date(value) : new Date() So in case when you provide your own alias for date - you need to provide map function

NOTE: The mapping function is serialized so its required to not to have any references in outer scopes

Tags

Tags allow to replace node values according to match:

{
  // Allows to pass optional map function
  tags: [
    // This tags replace first empty symbol if value starts with /
    // Example: /link -> urlBase/link
    [/^(?=\/)/, urlBase],
  ],
}

Note: Tags applied recursively, item.field.inner (value) is affected

Quick Setup

  1. Add nuxt-feedme dependency to your project

Use your favorite package manager (I prefer yarn)

yarn add -D nuxt-feedme

pnpm add -D nuxt-feedme

npm install --save-dev nuxt-feedme
  1. Add nuxt-feedme to the modules section of nuxt.config.ts
export default defineNuxtConfig({
  modules: [
    // After nuxt content
    '@nuxt/content',
    'nuxt-feedme'
  ]
})

That's it! You can now use nuxt-feedme in your Nuxt app ✨
