Posted 2021-05-03

import LIVR from 'livr';

const isPrimitiveValue = (value) => {
  if (typeof value == 'string') return true;
  if (typeof value == 'number' && isFinite(value)) return true;
  if (typeof value == 'boolean') return true;
  return false;
}

const boolean = () =>
  return (value, params, outputArr) => {
    if (value === undefined || value === null || value === '') return;
    if (!isPrimitiveValue(value)) return 'FORMAT_ERROR';

    if (['1', 1, 'true', true].indexOf(value) >= 0) {
        outputArr.push(true);
        return;
    } else if (['0', 0, 'false', false].indexOf(value) >= 0) {
        outputArr.push(false);
        return;
    }

    return 'NOT_BOOLEAN';
  };


LIVR.Validator.registerDefaultRules({ boolean });
