Building A Playground with Nuxt and Markdown

I've been playing around with Nuxt lately for prototyping ideas for myself and for clients. I've really liked having the ability to bootstrap an app from the command line with a handful of really useful base tools. Nuxt has some goodies that I can take advantage of right off the bat:

  • It's a framework for creating Vue apps that abstracts away the client/server complexities. This means we can use it as a jumping-off point for a new app or to plug into existing APIs.
  • A command line that generates a shell app from a starter template, where server-side rendering is built-in for SEO and quick load times.
  • Pulling in a server-side framework (if necessary, but it's not always), a UI framework, a testing framework, linting and prettifying, a library (Axios) for making HTTP requests.

For this project, I wanted a basic markdown blog experience with Vue and Nuxt so that I can have a playground for both.

Here's how that went and how you can roll your own too. We'll run through these steps:

  • Create a Shell App
  • Load Markdown Files
  • Show a Blog Post
  • Show a List of Posts
  • Generate Dynamic Routes for Static Site

And end up with this.

Or if you're impatient, grab it from the GitHub repo here.

Create a Shell App

Create a shell app from the default Nuxt starter template by running the following from your command line:

yarn create nuxt-app starter-for-nuxt-markdown-blog

Here's what that output looks like:

After creating the app, check out what the default Nuxt starter template looks like by spinning it up with:

yarn dev

Then head on over to http://localhost:3000.

Load Markdown Files

Next, we'll use the frontmatter-markdown-loader package to pull in markdown files from a directory named content and gain access to markdown frontmatter (metadata about the markdown file, in this case, post metadata like the title, tags, a hero image) for each post.

Add the package:

yarn add frontmatter-markdown-loader

Create the content directory:

mkdir -P content/blog

To create the first post, drop this file in content/blog.

Then create an associated directory for image assets:

mkdir -P assets/images/blog

And add this image to assets/images/blog.

Now that we have some content, we can extend the webpack config by adding the frontmatter-markdown-loader to the build step in nuxt.config.js:

build: {
    extend(config, ctx) {
            test: /\.md$/,
            include: path.resolve(__dirname, "content"),
            loader: "frontmatter-markdown-loader",
Enter fullscreen mode Exit fullscreen mode

Show a Blog Post

We don't need to create static pages for each post we have, so instead, we'll use dynamic routing to pull in the markdown file. Consider the following URL paths:






In both of these examples, :blog_post_title and :username represent the dynamic part of the route, or the slug.

Create the blog directory:

mkdir pages/blog

We'll create the blog directory and add a _slug.vue file. This _slug.vue file will be the Vue template for our blog post. In pages/blog/_slug.vue, add the following basic template:

      <div class="container">
        <h1 class="title">
          {{ post.attributes.title }}
        <h2 class="subtitle">
          {{ }}
        <div class="columns">
          <div class="column is-half is-offset-one-quarter">
            <figure class="image">
              <img :src="imgSrc">
        <!-- eslint-disable-next-line -->
        <div class="content" v-html="post.html" />
    export default {
      computed: {
        imgSrc () {
          return require(`~/assets/images/blog/${}`)
      async asyncData ({ params }) {
        try {
          const post = await import(`~/content/blog/${params.slug}.md`)
          return {
        } catch (error) {
          return false
      head () {
        return {
Enter fullscreen mode Exit fullscreen mode

In asyncData we've imported the markdown file based on the slug value that we get from the params. Again, the slug is defined by the URL. For instance, the slug for our URL http://localhost:3000/blog/2019-09-22-veggies is 2019-09-22-veggies, so this will import the file and assign the post object to the component's data.

We're using the v-html directive in order to render raw HTML from our markdown. This causes an eslint warning:

9:26 warning 'v-html' directive can lead to XSS attack vue/no-v-html

You can read more about XSS vulnerabilities here and here. Be sure you know where your content is coming from — if you're writing it, know that even third-party UI libraries can create security vulnerabilities. We can get rid this warning of by ignoring it with the eslint-disable-next-line line directly above.

Now we can point our browser at http://localhost:3000/blog/2019-09-22-veggies and see the post!

Show a List of Posts

The next step is to be able to show a list of blog posts from our home page and be able to navigate to each individual post.

So that we have more than one post to show in our blog post list, add this post to content/blog and it's image to assets/images/blog.

In pages/index.vue, we're going to use Nuxt's asyncData method again to load all the blog posts so that we can display them on the page. In the future, we could paginate these or only load in featured posts to display on the home page of the site. We'll then add a v-for loop in the template to display the posts.

      <div class="container">
        <h1 class="title">
          Blog Posts
        <section class="posts">
          <div v-for="post in posts" :key="post.attributes.title" class="columns">
            <div class="column is-one-quarter">
              <figure class="image">
                <img :src="imgSrc(post)" :alt="post.attributes.title">
            <div class="column is-three-quarters">
              <p class="title is-4">
                <nuxt-link :to="post._path">
                  {{ post.attributes.title }}
              <p class="subtitle is-6">
                {{ post.attributes.tags }}
              <div class="content">
                <p>{{ post.attributes.excerpt }}</p>
                <p>{{ }}</p>
                <nuxt-link :to="post._path">

    export default {
      async asyncData () {
        const context = await require.context('~/content/blog', true, /\.md$/)
        const posts = await context.keys().map(key => ({
          _path: `/blog/${key.replace('.md', '').replace('./', '')}`
        return { posts: posts.reverse() }
      methods: {
        imgSrc (post) {
          return require(`~/assets/images/blog/${post.attributes.hero}`)

Enter fullscreen mode Exit fullscreen mode

Here we're loading in all the markdown files in the content/blog directory and any subdirectories (as indicated by true). Then we're mapping each key (the file name) to its context and anything else we want. In this case, we're also mapping _path to the URL path to the post so we can build links later. The context ends up being what frontmatter-markdown-loader loads: attributes (the frontmatter of the markdown file) and html (the markdown compiled to HTML).

Now, when we point our browser back to http://localhost:3000/ we should see this:

Blog index page

Generate Dynamic Routes for Static Site

We still have one step left and that is to set up the dynamic routes to work with yarn generate, the step that generates a static site for production. In nuxt.config.js, we're going generate routes based on the markdown files we have in the content directory.

First, add const glob = require('glob') at the top of the file and then define markdownPaths there as well:

const markdownPaths = ['blog']

This will be an array of... paths to our markdown files. In our case, we only have one, but you could extend this to be ['blog', 'portfolio', 'photos', 'recipes'] or whatever you need.

Then at the bottom of this file, we'll add this function:

function dynamicMarkdownRoutes() {
  return [].concat( => {
      return glob.sync(`${mdPath}/*.md`, { cwd: 'content' })
        .map(filepath => `${mdPath}/${path.basename(filepath, '.md')}`);
Enter fullscreen mode Exit fullscreen mode

We'll call that function in the generate.routes block. This can be added at the same level as modules or build:

generate: {
  routes: dynamicMarkdownRoutes()
Enter fullscreen mode Exit fullscreen mode

To test this out, we'll head back to the command line and run yarn generate, which should produce this output:

This will generate your site in the dist directory. If you'd like to test it out (and you probably should!) before deploying it live, you can also run yarn build and then yarn start to start up an HTTP server of the static site in that directory.

Hopefully, this gets you started with building a blog using Nuxt and markdown files! You can grab this version of the code from here. I'll be continuing to update this repo as I build it out more. Maybe we'll dig into those warnings about "cannot stringify POJOs with symbolic keys" or formatting the date display using Moment.js or even hooking it up to a headless CMS next.

Ready to get started with this as your starter on Netlify right now? You can do that too!

@jennapederson good article! Not sure if you have any thoughts on using markdown vs HTML for the editor?

Thanks, @kp ! I assume you're asking why write posts in markdown instead of HTML?

It quite likely depends on your user and who is writing the content, as well as how often that content changes. For instance, not every writer knows or is comfortable with HTML so being able to put words down on the screen without having the overhead of HTML can be important. For me, when I'm writing I just want to write and not worry about code. Markdown lets me focus on the task at hand, which is writing.

kp profile image

Hi @jennapederson thanks for the response! Sorry, I didn't ask my question clearly...I did not mean writing HTML. I meant using a WYSIWYG editor like tiptap versus Markdown. I do agree that the audience matters a lot :)

Oh, awesome! I hadn't heard of tiptap! I've used other similar ones like quill, ckeditor, and TinyMCE. In this case, I really wasn't planning to build out an editing workflow here. For this particular use case, if it were more than just me writing my own posts, I'd probably go with a headless CMS rather than rolling my own editor workflow.

But that being said, I like the idea of those editors for the right use case, maybe where the user is less familiar with markdown markup but more familiar with something like Word. I'll have to take a closer look at tiptap next time!

Glad the pointer on tiptap helped! It looks neat and I plan to use it. I have still to wrap my head around headless CMS (pun fully intended :D)
