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.

/**
 * Options of this type must be specified at most once.
 * @param option The option being validated (ex. $top)
 * @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
 */
