cacheable middleware usage

// before
router.get('/:id(\\d+)', (req, res, next) => {
    cacheClient.getAsync(cacheKey).then(cacheObj => {
        if(cacheObj) {
            debug("got from cache");
            return res.send(JSON.parse(cacheObj));
        } else {
            let params = {
                idStore   : req.idStore,
                idCatalog : req.params.id,
                start     : parseInt(req.query.start),
                end       : parseInt(req.query.end)
            };

            catalogBusiness.getEditorialCatalogByIdStore(params).then(catalog => {
                if (!lodash.isEmpty(catalog)) {
                    debug("setting cache value for ", cacheKey);
                    cacheClient.setAsync(cacheKey, JSON.stringify(catalog));
                }
                return res.send(catalog);
            }).catch(err => {
                debug(err);
                next(err);
            });
        }
    });
});

// after
router.get('/:id(\\d+)', cacheable(), (req, res, next) => {
    let params = {
        idStore   : req.idStore,
        idCatalog : req.params.id,
        start     : parseInt(req.query.start),
        end       : parseInt(req.query.end)
    };

    catalogBusiness.getEditorialCatalogByIdStore(params).then(catalog => {
        return res.send(catalog);
    }).catch(err => {
        debug(err);
        next(err);
    });
});
