Building Modern Web Applications with Next.js and Sanity

When building content-rich platforms today, decoupling your content management from the frontend presentation is no longer just a luxury—it is an architectural necessity. Combining Next.js App Router with Sanity Studio produces a developer and author experience that feels lightyears ahead of traditional monoliths.

End-to-End Type Safety with TypeGen

One of the most transformative additions to the Sanity ecosystem is official Sanity TypeGen. Instead of maintaining separate TypeScript interfaces by hand that drift out of sync with your GROQ queries, TypeGen extracts your static schema JSON and derives exact return types automatically for every query wrapped in defineQuery.

1import { defineQuery } from 'next-sanity'
2 
3export const POST_QUERY = defineQuery(`
4  *[_type == "post" && slug.current == $slug][0]{
5    _id,
6    title,
7    slug,
8    publishedAt,
9    excerpt,
10    author->{
11      name,
12      role,
13      image
14    },
15    categories[]->{
16      title,
17      "slug": slug.current
18    },
19    body
20  }
21`)

Edge Caching & Instant Invalidation

Next.js Incremental Static Regeneration (ISR) pairs seamlessly with Sanity's globally distributed CDN. By setting a measured revalidation window, pages load instantly as pre-rendered static HTML from the edge, while content updates in Sanity propagate without triggering complete site rebuilds.
