Update Data in Cache

You can update the key-value pair in a cache segment using the update() method. You must pass the key name and key-value which are of the String type as arguments. If the values aren't present, they will be inserted into the cache segment. The promise returned here will be resolved to a JSON object.

You can also optionally pass the expiry time parameter. If you don't assign a value for that, the expiry time will be set to 48 hours by default.

The segment reference used in the code snippet below is the segment instance created earlier.

Copied//Update cache by passing the key-value pair
    let cache = app.cache();
    let segment = cache.segment();
    let cachePromise = segment.update('Name', 'Micheal Greene');
    cachePromise.then((entity) => {
            console.log(entity);
        });

A sample response that you will receive for each version is shown below:
