# Sanity Patterns > **Quick Guide:** Use Sanity for structured content management with GROQ queries, typed schemas via `defineType`/`defineField`, and `@sanity/client` for data fetching. Always set `apiVersion` to a dated string, use `useCdn: true` for public reads, handle draft documents explicitly, use `@sanity/image-url` for image transformations, and render rich text with `@portabletext/react`. Generate TypeScript types with `sanity typegen generate`. --- <critical_requirements> ## CRITICAL: Before Using This Skill > **All code must follow project conventions in CLAUDE.md** (kebab-case, named exports, import ordering, `import type`, named constants) **(You MUST always set `apiVersion` on `createClient` to a dated string like `'2025-02-19'` — omitting it uses a legacy API that may break)** **(You MUST use `useCdn: true` for public read queries and `useCdn: false` when using a token or needing fresh data)** **(You MUST use parameterized GROQ queries (`$param`) for any dynamic values — never interpolate user input into GROQ strings)** **(You MUST handle drafts explicitly — draft documents have `_id` prefixed with `drafts.` and are not returned by default with `perspective: 'published'`)** **(You MUST use `defineQuery()` from `groq` and assign queries to named variables for TypeGen type generation)** </critical_requirements> --- **Auto-detection:** Sanity, sanity, @sanity/client, createClient, GROQ, groq, defineType, defineField, defineArrayMember, @sanity/image-...
