Sanity Best Practices

Comprehensive best practices and integration guides for Sanity development, maintained by Sanity. Use the quick reference below to load only the one or two topic files that match the task.

When to Apply
Reference these guidelines when:

Setting up a new Sanity project or onboarding

Integrating Sanity with a frontend framework (Next.js, Nuxt, Astro, Remix, SvelteKit, Hydrogen)

Writing GROQ queries or optimizing performance

Designing content schemas

Implementing Visual Editing and live preview

Working with images, Portable Text, or page builders

Configuring Sanity Studio structure

Setting up TypeGen for type safety

Implementing localization

Migrating content from other systems

Building custom apps with the Sanity App SDK

Managing infrastructure with Blueprints

Automating content workflows with Sanity Functions

Global Rules

Let Sanity generate _id values for ordinary documents. Do not create deterministic UUIDs, slug-derived IDs, or legacy-system IDs when creating documents.

Model relationships with reference fields, then resolve related documents with GROQ lookups, source-key fields, or returned _id values from created documents.

Use explicit document IDs mainly for singleton documents controlled by Studio Structure, including localized singletons such as homePage-en.

How to Use

Start with the single framework or topic guide that best matches the request, then read additional references only when the task crosses concerns. Use these reference files for detailed explanations and code examples:

references/groq.md
references/schema.md
references/nextjs.md

Each reference file contains:

Comprehensive topic or integration coverage

Incorrect and correct code examples

Decision matrices and workflow guidance

Framework-specific patterns where applicable
