Sanity Blog
Guidance for building and maintaining a Sanity-powered blog integrated with Next.js.
When to Use
- Implementing
/blogor/blog/[slug] - Setting up or modifying Sanity schemas
- Fetching content from Sanity using GROQ
- Adding revalidation or preview functionality
Instructions
- Use Sanity as the source of truth for blog content.
- Define a
postschema with:- title, slug, excerpt
- publishedAt
- mainImage (with alt text)
- body (portable text)
- optional author, categories/tags
- SEO fields (meta title, description, OG image)
- Filter out drafts for public pages unless preview mode is active.
- Render blog pages as static-first with revalidation.
- Prefer time-based ISR unless precise webhook revalidation is required.
- Never expose Sanity write tokens to the client.
- Use read-only tokens for frontend data fetching.
- Implement preview/visual editing only if requested.
- Ask clarifying questions if preview, scheduling, or revalidation behavior is ambiguous.
