Sanity TypeGen Workflow

I'll help you generate TypeScript types from your Sanity schema.

Quick Start

npm run typegen
# or
npx sanity schemas extract && npx sanity typegen generate

What I'll Do

1. Check Configuration

   • Check for typegen config in sanity.cli.ts (recommended)
   • If using deprecated sanity-typegen.json, suggest migrating to sanity.cli.ts
   • Ensure typegen script is in package.json (for manual workflows)

2. Run TypeGen

   • Execute the typegen command
   • Report any errors

3. Troubleshoot Issues

   • Fix incorrect path globs
   • Resolve schema syntax errors
   • Update query imports
   • Migrate deprecated sanity-typegen.json to sanity.cli.ts

Common Issues I Fix

Issue	Solution
"No schema found"	Fix path glob in sanity.cli.ts typegen config
"Query not typed"	Wrap in defineQuery() or groq template
Types outdated	Re-run after schema/query changes, or enable automatic generation
Import errors	Check sanity.types.ts output path
Using sanity-typegen.json	Migrate config to sanity.cli.ts (deprecated)

Configuration

Configure TypeGen in sanity.cli.ts:

// sanity.cli.ts
import { defineCliConfig } from 'sanity/cli'

export default defineCliConfig({
  typegen: {
    enabled: true, // Auto-generate during sanity dev/build
    path: "./src/**/*.{ts,tsx,js,jsx,astro,svelte,vue}",
    schema: "schema.json",
    generates: "./sanity.types.ts",
    overloadClientMethods: true,
  },
})

Usage

"Run typegen" "Fix my TypeGen configuration" "Why are my types not updating?" "Enable automatic type generation"
