Simple & Fast Node.JS memory caching

  • Support: hex store, object, array, string, integer, boolean….
  • Full-featured: A simple caching setItem, getItem and deleteItem methods and works a like redis. Keys can have a timeout (ttl) after which they expire and are deleted from the cache. All keys are stored in a single object so the practical limit is at around 1m keys.


  • Node.js, at least v12 >


Initialize (INIT):

const nopeRedis = require("nope-redis");

Store a key (setItem):

Sets a key value pair. It is possible to define a ttl (in seconds). Returns true on success.

let obj = { name: "orhan", age: 26 };
result = nopeRedis.setItem("user1", obj,  10 );
// true

Retrieve a key (getItem):

Gets a saved value from the cache. Returns a null if not found or expired. If the value was found it returns the value.

result = nopeRedis.getItem("user1");
	// no data
// { name: "orhan", age: 26 }

Delete a key (deleteItem):

Delete a key. Returns the true or false.

result = nopeRedis.deleteItem("user1");
// true

Flush all keys (flushAll)

Flush all data.

result = nopeRedis.flushAll();
// true

Store Statistics (stats)

Returns the statistics.

result = nopeRedis.stats({ showKeys: true, showTotal: true, showSize: true });
			"killerIsFinished": true,

			"nextKiller": 1647245886,

  • killerIsFinished: The ttl value indicates whether the function is finished deleting obsolete values.
  • lastKiller: The unix timestamp value of the last time old values were deleted.
  • nextKiller: The unix timestamp value when it will delete old values.
  • criticalError: is the value of how many times it gets critical errors and therefore how many times it reboots itself “nope-redis”.
  • total: Key count
  • keys: Array of all existing keys.
  • size: Value size count in approximately file size (Bytes, KB, MB, GB, TB)


  • key must be string,
  • default ttl is 30 seconds
