How to integrate ButterCMS into your Astro application

Integrating the Butter blog engine into your Astro app is dead simple. Here's a mini tutorial to get a feel for setting up your blog home and blog post pages. 

For a full integration guide, check out our Official Astro Guide. Before you get started, you'll want to install ButterCMS into your app, or you can load from CDN.

There are a number of ways to integrate your ButterCMS blog into your app. The easiest is with Server-side Rendering, or SSR.

To switch to Server-side Rendering, open your astro.config.mjs file and add the output:'server' option to your defineConfig():

export default defineConfig({
  output: 'server',

We're going to be making three different routes:

  • A main blog view, which will server as the basis of your blog home and display a list of your 10 most recent posts,
  • An archive routes to let users paginate through older blog posts, which passes the post slug in as a parameter,
  • And individual blog post pages.

Let's start by setting up our individual blog post pages. This will include information such as author, publish date, and categories. See a full list of available post properties in our API reference.

Create a new folder, blog, inside of /src/pages/. Then, create a file, [slug].astro.


//code block 
import Butter from "buttercms";

/* We recommend instantiating Butter with a utility class, such as this example:,
but we'll just do it in this file for now */

const butterCMS = Butter("your_api_token");

// Let's pull the slug from the Astro params and grab our posts from Butter
const postSlug = Astro.params.slug
const postData = await;

// To make the template simpler, we'll store our needed data as just post
const post =

<!---html block-->
    <title>{ post.seo_title }</title>
    <h1>{ post.title }</h1>
    <!-- Post author + Publish date. We're not actually going to set up routes/pages
    for authors and categories, but it's shown here for reference-->
      Posted by <a href={"/blog/author/" + + "/"}>{ } { }</a> on { post.published }
    <!-- Post categories -->
      { => (
        <li><a href={"/blog/category/" + category.slug + "/"}>{ } </a></li>
    <Fragment set:html={ post.body }/>

For the blog list routes, because so much of the code will be similar, we're going to expand our app out with a utility function and a layout that will avoid too much repetition.

Let's start with our utility file, which will allow us to make our call to Butter to get our post list. It will also return some metadata we can use for pagination.

Make a new directory inside of your srcfolder, utils, and create a file, BlogRoll.js.


import Butter from 'buttercms';
const butterCMS = Butter('your_api_token');

async function getPostsData(page = null) {
  /* Grab posts from Butter. Specify number of results to fetch with page_size.
  For example, you can set to "1" to test pagination functions*/
  const postsData = await{ page_size: 10, page: page });
  // Get next and previous pages for pagination
  const nextPage =;
  const previousPage =;
  const posts =;
  return { nextPage, previousPage, posts };

export default getPostsData;

Great. Now, let's create our layout file, which will get recycled between the two different blog views.

Make a new file inside of your src/layouts/folder, BlogLayout.astro.


//code block

const {posts, previousPage, nextPage, page } = Astro.props
      <!-- Note that conditional display of html in Astro uses jsx logical operators and 
      ternary expressions-->
      <title>{page ? "Blog Posts, Page " + page : "All Blog Posts" }</title>
    <h1>{page ? "Blog Posts, Page " + page : "All Blog Posts" }</h1>
    <!-- List of Posts -->
      { => (
      <li><a href={"/blog/" + post.slug + "/"}>{ post.title }</a></li>

    <!-- List of Posts -->
    { previousPage ? <a href={"/blog/page/" + previousPage}>Previous Page</a> : "Previous Page"}
    { nextPage ? <a href={"/blog/page/" + nextPage}>Next Page</a> : "Next Page"}

Great. Now that we've created our utility file and our Layout, it's time to create our blog list views.

Inside of your blog folder, make a new file, index.astro.


//code block 
import BlogLayout from "../../layouts/BlogLayout.astro"
import getPostsData from "../../utils/BlogRoll.js"

const {nextPage, previousPage, posts, page} = await getPostsData();

  nextPage={nextPage} previousPage={previousPage} posts={posts}>

Inside of your blog folder, also make a new folder, page, and create a [page].astro file.


//code block 
import BlogLayout from "../../../layouts/BlogLayout.astro"
import getPostsData from "../../../utils/BlogRoll.js"

// Get page from URL Route
const page =;
const {nextPage, previousPage, posts} = await getPostsData(page);

  page={page} nextPage={nextPage} previousPage={previousPage} posts={posts}>

That's it! If you restart your development server, you should be able to access the following new routes in your app: /blog/, /blog//, and /blog/page//
