Recursively maps a statically-known JSON Schema node (passed with as const) to the exact @cleverbrush/schema builder type, including:

StringSchemaBuilder, NumberSchemaBuilder, BooleanSchemaBuilder for primitive types and const literals
ArraySchemaBuilder<ElementBuilder> with the element builder inferred from items
ObjectSchemaBuilder<PropertyDescriptors> where each property is a typed builder with TRequired = true/false driven by the required array
UnionSchemaBuilder<[...Builders]> for enum and anyOf

Type Parameters

S
The JSON Schema node type (inferred from as const).
TRequired extends boolean = true
Whether this node represents a required (true) or optional (false) value in its parent context. Defaults to true.

Example

import { fromJsonSchema } from '@cleverbrush/schema-json';
import type { JsonSchemaNodeToBuilder } from '@cleverbrush/schema-json';

const S = {
  type: 'object',
  properties: {
    name:  { type: 'string' },
    score: { type: 'number' },
  },
  required: ['name'],
} as const;

type Builder = JsonSchemaNodeToBuilder<typeof S>;
// ObjectSchemaBuilder<
//   { name: ExtendedStringBuilder<string, true> } &
//   { score: ExtendedNumberBuilder<number, false> }
// >

const schema = fromJsonSchema(S);
// TypeScript knows schema is ObjectSchemaBuilder<...>
// with full intellisense on .parse(), .addProp(), etc.
