Complex solution to work with pageable data, including sorting, filtering, actions, changing displayed columns, etc.

export default function strToSort(str) {
    if (!str)
        return undefined;
    if (typeof str === 'string') {
        var sortBy = strToSortBy(str);
        if (!sortBy)
            return undefined;
        return [sortBy];
    }
    var strAsArray = str;
    var resultArray = strAsArray.map(strToSortBy).filter(function (x) { return !!x; });
    return !resultArray ? undefined : resultArray;
}
function strToSortBy(str) {
    if (!str)
        return undefined;
    var commaIndex = str.indexOf(',');
    if (commaIndex === -1) {
        return { field: str, direction: 'ASC' };
    }
    var field = str.substring(0, commaIndex);
    var strDir = str.substring(commaIndex + 1);
    return { field: field, direction: strDir.toUpperCase() === 'DESC' ? 'DESC' : 'ASC' };
}
