Live Blog: Sanity Live Content API Example with Next.js

This is a demo of using Sanity's Live Content API to power a live blog.

The Live Content API makes it possible to automatically re-fetch content updates from the Sanity CDN.

In this example, we use a canary of the next-sanity toolkit to import a client that can generate a <LiveSubscription /> component that you can add to any component to make it automatically fetch published content live. It works with React Server Components (no "use client" needed).

This demo relies on Next.js’ searchParams, which must be passed down from the route component.

Try the demo locally

1. Clone this repo
2. Install its dependencies (pnpm i)
3. Run pnpm dlx sanity@latest init --env to create a Sanity project and add the configuration to an .env file
4. Run pnpm dlx sanity dataset import demo.tar.gz production to import some demo data
5. Run pnpm dev to start the dev server
6. If you open http://localhost:3000/studio you will be asked to add it to your project’s CORS origin settings (pnpm dlx sanity cors add http://localhost:3000 --credentials will also do the trick)
7. And you should be good to go!

Note that this demo uses the experimental (vX) version of the Live Content API, and hence you will get some warnings in your console while you're running it.

• v0 for initial UI generation
• Tailwind.css for styling
• Next.js App Router with React Server Components
• Sanity as the CMS and Live Content API
• Sanity TypeGen for TypeScript type generation for the content
• Some light sprinkeling of TypeScript
