Commerce Cloud Personalized Caching via Script API

scriptingAPIExample.js

// SFRA controller cached via decorator
server.get('Show', cache.applyDefaultCache, function (req, res, next) {} );

// set cache time directly at the response (does not rely on SFRA)
response.setExpires(new Date().getTime() + durationInMinutes * 60 * 1000);

// apply personalised caching
response.setVaryBy('price_promotion');

// Cache times do not have to be constants - let's get creative!
// apply layered caching times by product availability levels
var availabilityModel = product.getAvailabilityModel();
if (availabilityModel.isOrderable(50)) {
    // cache 5 days when >= 50 orderable
    response.setExpires(new Date().getTime() + 120 * 60 * 60 * 1000);
} else if (availabilityModel.isOrderable(20)) {
    // cache 1 day when >= 20 orderable
    response.setExpires(new Date().getTime() + 24 * 60 * 60 * 1000);
} else if (availabilityModel.isOrderable(5)) {
    // cache 4 hours when >= 5 orderable
    response.setExpires(new Date().getTime() + 4 * 60 * 60 * 1000);
} else {
    // cache 30 minutes when < 5 orderable
