How to integrate ButterCMS into your Astro application

Just follow the simple steps below to complete the integration and begin creating pages with Butter. Be sure to check out our full guide to creating pages using the ButterCMS Astro API. Make sure you've installed our SDK with $ npm install buttercms --save, or you can load Butter via CDN.

1. First, you would set up a new Customer Case Study page type in Butter and create a page. With your page defined, the ButterCMS API will return it in JSON format like this:

    "data": {
        "slug": "acme-co",
        "fields": {
            "facebook_open_graph_title": "Acme Co loves ButterCMS",
            "seo_title": "Acme Co Customer Case Study",
            "headline": "Acme Co saved 200% on Anvil costs with ButterCMS",
            "testimonial": "<p>We've been able to make anvils faster than ever before! - <em>Chief Anvil Maker</em></p>\r\n<p><img src=\"\" alt=\"\" caption=\"false\" width=\"249\" height=\"249\" /></p>",
            "customer_logo": "",

2. The easiest way to integrate these pages in our app is going to be with server-side rendering

To enable in this in your app (if you haven't already), open your astro.config.mjs file and add the output:'server' option to your defineConfig():

export default defineConfig({ 

3. Now, create a new directory, customers, in your src/pages/ directory. Inside of this directory, create a new file, [slug].astro. This filename convention will allow you to dynamically pass the slug from ButterCMS as a new astro url route.


//code block 
import Butter from "buttercms";

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

const butterCMS = Butter("your_api_token");

// Grab the slug from the filename to fetch data from Butter and store Page fields as PageFields
const caseStudyPageData = await"case_study", Astro.params.slug);
const pageFields =
    <title>{ pageFields.seo_title }</title>
    <meta property="og:title" content="{ pageFields.facebook_open_graph_title }" /> 
    <h1>{ pageFields.headline }</h1>
    <img width="100%" src={ pageFields.customer_logo }>
    <p set:html={ pageFields.testimonial } />

That's it! If you browse to /customers/acme-co/, you'll see your page populated with the content you created in Butter.
