json-schema-some
Array.prototype.some for JSON Schema.
This package uses json-schema-traverse and exports a function some. This function gets an object as argument, and is expected to return a boolean. If it returns true, some returns true, otherwise false.
The argument the callback gets is an object containing the arguments array provided in the callback to traverse in json-schema-traverse. Check that documentation for further information. The object form is:
interface CallbackArgument
{
schema: SchemaObject;
jsonPtr: string;
rootSchema: SchemaObject;
parentJsonPtr?: string;
parentKeyword?: string;
parentSchema?: SchemaObject;
keyIndex?: string | number;
}where SchemaObject is a valid JSON Schema object.
Example
import { some } from 'json-schema-some'
// Returns true if any schema object in the schemaObject tree is of type
// 'object', with 'properties' and a property called 'firstName'
const hasFirstName = some( schemaObject, ( { parentKeyword, keyIndex } ) =>
parentKeyword === 'properties' && keyIndex === 'firstName'
);
