NCache is a 100% open Source in-memory distributed cache. NCache is an extremely fast and linearly scalable distributed cache that caches application data and reduces expensive database trips. Use NCache removes performance bottlenecks related to your data storage and databases and scales your node.js applications to extreme transaction processing (XTP).



NCache Node.js client requires a working NCache cluster to run. This cluster handles the storage and manipulation of the user data.


npm install ncache-client



const ncache  = require('ncache-client');

//Initialize the Cache Cluster 
let cache = await ncache.CacheManager.getCache("test-Cache");

//Add data in Cache 
await cache.add('key', new ncache.CacheItem("Value"));

// Get the value associated with the given key from cache
const cacheValue = await cache.get('key', ncache.JsonDataType.Scaler);

console.log("Item in cache"+ cacheValue +" against key "+'key'); //Outputs 'Value'

//close the cache
await cache.close();
