Install

npm install @portabletext/to-html @portabletext-typed/to-html

Usage

After using @sanity-typed/types and @sanity-typed/client and you have typed blocks, use toHTML from this library as you would from @portabletext/to-html to get fully typed arguments!

post.ts:

// import { defineArrayMember, defineField, defineType } from "sanity";
import {
  defineArrayMember,
  defineField,
  defineType,
} from "@sanity-typed/types";

/** No changes using defineType, defineField, and defineArrayMember */
export const post = defineType({

    defineField({

      validation: (Rule) => Rule.required(),

        defineArrayMember({ type: "image" }),
        defineArrayMember({

          styles: [
            { title: "Normal", value: "normal" as const },
