cacheman-memory

library1.1.0jsnpmunverified

An in-memory caching library for Node.js, version 1.1.0, serving as a cache engine for the cacheman module. It provides a simple key-value store with TTL support and callback-based API. Unlike persistent stores like Redis or Memcached, this is lightweight and zero-config, suitable for single-process caching. Last updated in 2013, it is no longer actively maintained but still functional for legacy projects. The package is stable but deprecated in favor of modern alternatives like lru-cache or native Map.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

CachemanMemory

✓ import CachemanMemory from 'cacheman-memory';

✗ const cachemanMemory = require('cacheman-memory');

ESM default import works; CommonJS require also works since the package is not strictly ESM.

CachemanMemory

✓ const CachemanMemory = require('cacheman-memory');

✗ import { CachemanMemory } from 'cacheman-memory';

CommonJS require is the most common pattern; named import fails because the module exports a single constructor as default.

new CachemanMemory()

✓ let cache = new CachemanMemory();

✗ let cache = CachemanMemory();

Must use new operator; calling without 'new' assigns to global object.

Demonstrates creating a memory cache, setting an item with TTL, retrieving it, and deleting it using callbacks.

import CachemanMemory from 'cacheman-memory'; const cache = new CachemanMemory(); cache.set('myKey', { foo: 'bar' }, 60, (err) => { if (err) { console.error(err); return; } cache.get('myKey', (err, value) => { if (err) throw err; console.log(value); // { foo: 'bar' } cache.del('myKey', (err) => { if (err) throw err; console.log('deleted'); }); }); });

Debug

Known issues

deprecatedPackage is no longer maintained; last update 2013.

fix

Consider using lru-cache or native Map for in-memory caching.

affects: >=0.0.0

gotchaCallback-based API; no promise support. All operations use Node-style callbacks.

fix

Wrap with util.promisify or use modern alternatives.

affects: >=0.0.0

breakingPossible global scope pollution if CachemanMemory is called without 'new'.

fix

Always use the 'new' keyword to instantiate.

affects: >=0.0.0

gotchaTTL is in seconds, not milliseconds.

fix

Convert milliseconds to seconds before passing ttl.

affects: >=0.0.0

gotchaget() returns null for missing keys, not undefined.

fix

Check for null explicitly.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: cache.set is not a function

CachemanMemory instance not created with 'new', so cache is undefined.

fix

const cache = new CachemanMemory();

TypeError: cache.get(...) is not a function

CachemanMemory instance not created with 'new', so cache is undefined.

fix

const cache = new CachemanMemory();

Cannot find module 'cacheman-memory'

Package not installed or typo in require/import.

fix

npm install cacheman-memory

Error: callback is not a function

Missing callback argument in set/get/del/clear.

fix

Always pass a callback function to async methods.
