Generating RSS Feed using Nuxt feed module

Post created on: 10/5/2020

Moving from Gridsome to Nuxt for most of this was fairly straightforward as it is from one vue framework to another the majority of the content stayed the same including the use of netlifyCMS for creating my blog posts. I had to setup pulling posts differently using asyncData but reading the docs I found that more straightforward than trying to use GraphQL (which I don't know much about) as I did with Gridsome. This was done with the help of great post in the official Nuxt blog here.

The main issue I have come across was setting up the RSS feed to be able to cross post on, but I have managed to get it setup using a combination of the docs and a post I found on

First install the module through npm or yarn and add it to modules in your nuxt.config.js file and make sure to add it after the content module.

modules: [

There are a couple of different ways to it setup depending on your particular use case and setup as explained in the docs. The main difficulty I had was being able to access the markdown through nuxt/content and so back to the nuxt docs I went

There are a few different hooks available when using the content module in my case I'm using the content:file.beforeInsert hook which as detailed on the docs Allows you to add data to a document before it is stored. I used this to be able to get down the body content of my blog posts

The end result of a few hours of playing around and reading docs was this setup in nuxt.config.js in the default export with the create function setup outside this at the top of the file:

  feed: [
      path: '/feed.xml',
      create, // outside the default export at the top of the config file
      cacheTime: 1000 * 60 * 15,
      type: 'rss2',
      data: [ 'blog', 'xml' ]
  hooks: {
    'content:file:beforeInsert': (document) => {
      if (document.extension === '.md') {      
        document.bodyPlainText = document.text;

This is the create function referenced above:

let posts = [];

const constructFeedItem = (post, dir) => {  
  const url = `${post.slug}`;
  return {
    title: post.title,
    id: url,
    link: url,
    description: post.description,
    content: post.bodyPlainText

const create = async (feed) => {
  feed.options = {
    title: "My Web Dev Blog",
    description: "Documenting my web dev learnings",
    link: ``
  const { $content } = require('@nuxt/content')
  if (posts === null || posts.length === 0)
    posts = await $content('posts').sortBy('createdAt', 'desc').fetch();

  for (const post of posts) {
    const feedItem = await constructFeedItem(post);
  return feed;

I set an empty array to capture the posts and get their details in the constructFeedItem function and setup the main create function which needs to be asynchronous. Firstly set some base options in this case a title, description and link followed by requiring nuxt/content to be able to access $content to get my posts as you would on your blog page.

As made clear in the docs this can only be accessed after the module has been loaded so once the module is loaded check to make sure posts aren't empty and once check is complete I sort them in descending order by the createdAt option (one of the default options available with content module) and finally to add them to the feed itself I loop through the posts array add each post and return feed.
