Generating types from your schema

With the schema.json file created; you can now generate TypeScript types for your Sanity Studio schema. These types can be helpful in the Studio project, like customizations and contexts where you pass data that corresponds directly to the Studio schema types.

npx sanity@latest typegen generate

When successfully completed, this command creates a sanity.types.ts file containing TypeScript types for all your Sanity Studio schema types. Open it to find types for “built-in” schema types. If you have plugins with schema types, those will also be generated.

import type { Event } from './sanity.types.ts'

await client.create<Event>({
  _type: "event",
  _id: uuid(),
  // ... and other fields
})

While these types can come in handy in your Studio project, using them in your front end application is extremely useful to improve your development experience.
