Object Utilities

The object subpath contains query parsing and general object helpers.

import { parseQueryObject } from '@querry-kit/nest';
import { diffObjects, hasObjectDifferences, parseObject, serializeDecimalValues } from '@querry-kit/nest/object';

parseObject converts query-string values into JavaScript values and expands dotted keys.

parseObject({
  page: '1',
  enabled: 'true',
  deletedAt: 'null',
  tags: ['1', '2'],
  orderBy: '{"createdAt":"desc"}',
  'user.name': 'Ada',
});

parseQueryObject is the same normalization entry point used by QueryService for query-like values.

serializeDecimalValues recursively converts Decimal-like objects with a toNumber() method into numbers.

diffObjects and hasObjectDifferences compare nested objects and arrays.

ValidationUtil.mapValidationErrorsToObject(errors) maps class-validator errors into an object keyed by property name. It does not run validation itself.
