This blog uses Next.js to create a React blog. It uses Next.js 15 and the new Partial Prerendering to optimize performance and user experience. It connects to the Cosmic API via the Cosmic JavaScript SDK.

1. Log in to Cosmic and install the Simple Next.js Blog template.
2. Run the following commands to install the code locally.

git clone https://github.com/cosmicjs/simple-nextjs-blog
cd simple-nextjs-blog

1. Create an .env.local file to gain API access to your Cosmic Bucket. To do this, run:

cp .env.example .env.local

2. Find your API access keys at Bucket Settings > API Access after logging into your Cosmic dashboard and add them to the .env.local file. It should look something like this:

COSMIC_BUCKET_SLUG=your-bucket-slug
COSMIC_READ_KEY=your-bucket-read-key

Install all dependencies and run in development mode.

yarn
yarn dev

Open http://localhost:3000.
