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.

    

        
copy
        

            

        
    
    

         //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); });
