Next.js

Overview

This integration guide shows you how to how to update your existing project to:

install the ButterCMS package
instantiate ButterCMS
create components to fetch and display each of the three ButterCMS content types: Pages, Collections, and Blog Posts.

In order for the snippets to work, you’ll need to setup your dashboard content schemas inside of ButterCMS first.

Starter project

Or, you can jump directly to the starter project below, which will allow you to clone, install, run, and deploy a fully working starter project that’s integrated with content already inside of your ButterCMS account.

Next.js Starter Project

Hit the ground running with a pre-configured Next.js + ButterCMS setup.

Installation

npm
yarn
pnpm

npm install buttercms

yarn add buttercms

pnpm add buttercms

Add your API token to .env.local:

NEXT_PUBLIC_BUTTER_CMS_API_KEY=your_api_token

Initialize the client

Create a reusable client instance:

// lib/buttercms.ts
import Butter from 'buttercms';

const butter = Butter(process.env.NEXT_PUBLIC_BUTTER_CMS_API_KEY!);

export default butter;

For complete SDK documentation including all available methods and configuration options, see the JavaScript SDK Reference.

Preview Mode

Enable content editors to preview draft content before publishing.

App Router (Next.js 13+)
Pages Router (Next.js 12 and earlier)

// app/api/preview/route.ts
import { draftMode } from 'next/headers';
import { redirect } from 'next/navigation';

export async function GET(request: Request) {
  const { searchParams } = new URL(request.url);
  const slug = searchParams.get('slug');
  const secret = searchParams.get('secret');

  if (secret !== process.env.PREVIEW_SECRET) {
    return new Response('Invalid token', { status: 401 });
  }

  draftMode().enable();
  redirect(slug || '/');
}

Update your client to use preview mode:

// lib/buttercms.ts
import Butter from 'buttercms';
import { draftMode } from 'next/headers';

export function getButterClient() {
  const { isEnabled } = draftMode();
  return Butter(process.env.NEXT_PUBLIC_BUTTER_CMS_API_KEY!, {
    testMode: isEnabled,
  });
}

// pages/api/preview.ts
import type { NextApiRequest, NextApiResponse } from 'next';

export default function handler(req: NextApiRequest, res: NextApiResponse) {
  const { secret, slug } = req.query;

  if (secret !== process.env.PREVIEW_SECRET) {
    return res.status(401).json({ message: 'Invalid token' });
  }

  res.setPreviewData({});
  res.redirect(slug as string || '/');
}

Check preview mode in getStaticProps:

export const getStaticProps: GetStaticProps = async ({ preview }) => {
  const butter = Butter(process.env.NEXT_PUBLIC_BUTTER_CMS_API_KEY!, {
    testMode: preview,
  });
  // ... fetch content
};

SEO

// app/[slug]/page.tsx
import { Metadata } from 'next';
import butter from '@/lib/buttercms';

export async function generateMetadata({ params }): Promise<Metadata> {
  const response = await butter.page.retrieve('landing-page', params.slug);
  const page = response.data.data;
  const seo = page.fields.seo || {};

  return {
    title: seo.title || page.fields.headline,
    description: seo.description,
    openGraph: {
      title: seo.og_title || seo.title,
      description: seo.og_description || seo.description,
      images: seo.og_image ? [seo.og_image] : [],
    },
  };
}
