ncache-client

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

Installation

NCache

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

Client

npm install ncache-client

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

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

// 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();
