Code

Verified usage

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

Cache

✓ const Cache = require('kitten-cache');

✗ import Cache from 'kitten-cache';

Package uses CommonJS; ES import is not supported.

Cache

✓ const { Cache } = require('kitten-cache');

✗ const { Cache } = require('kitten-cache').default;

Direct named export is not available; the module exports a single constructor function.

Cache

✓ let cache = new (require('kitten-cache'))();

Alternative CommonJS pattern if preferred.

Shows creating a cache instance, setting and getting values, checking existence, and deleting entries.

const Cache = require('kitten-cache'); let cache = new Cache({ size: 100 }); cache.set('key1', 'value1'); cache.set('key2', 42); if (cache.has('key1')) { console.log(cache.get('key1')); // 'value1' } cache.delete('key2'); console.log(cache.get('key2')); // undefined

Debug

Known issues

gotchaCache size is not enforced strictly; the cache may exceed size if items are added quickly.

fix

Monitor cache size manually or use a different library for strict size limits.

affects: <=0.3.0

deprecatedNo support for TTL (time-to-live) expiration.

fix

Use lru-cache or node-cache if TTL is needed.

affects: all

gotchaPackage has no TypeScript type definitions.

fix

Create own .d.ts file or use // @ts-ignore.

affects: all

Errors

Common errors & fixes

Error: Cannot find module 'kitten-cache'

TypeError: Cache is not a constructor

Using ES6 import syntax instead of CommonJS require.

fix

Use: const Cache = require('kitten-cache');

cache.get is not a function

Cache instance not created correctly, e.g., calling Cache.get() directly on class.
