This package will help parse OData strings (only the Microsoft Dataverse subset). It can be used as a validator, or you can build some javascript library which consumes the output of this library.

const guidRegex = /[0-9A-F]{8}\-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{12}/gi;

/**
 * 
 * @param value The result of {@link URLSearchParams.getAll getAll}
 * @param result The {@link ODataQuery} to append the error to
 * @returns {boolean} Returns `false` when the parse has an error
 */
export const isGuid = (value, result) => {
  if (!value[0].match(guidRegex)) {
    result.error = {
      code: '0x0',
      message: 'Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).'
    };
    return false;
  }
  return true;
};
