cachefactory

library3.0.0jsnpmunverified

A simple synchronous key-value cache for the browser that supports TTL-based expiration with aggressive deletion, localStorage persistence, and manual cache management. Version 3.0.0 is the latest stable release, last updated in 2017. Key differentiators: minimalistic API, synchronous operations, optional localStorage backing, and automatic expiration recycling. The package ships TypeScript types. Maintenance is low, with no recent updates.

Verified usage

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

CacheFactory

✓ import { CacheFactory } from 'cachefactory'

✗ const CacheFactory = require('cachefactory')

ESM-only since v3

CacheFactory

✓ import CacheFactory from 'cachefactory'

✗ const CacheFactory = require('cachefactory'); const cacheFactory = new CacheFactory()

Default import also works in TypeScript with esModuleInterop

Cache

✓ import { Cache } from 'cachefactory'

✗ import { CacheFactory } from 'cachefactory'; const cache = new Cache()

Cache is exported as a named interface/class for TypeScript types

Shows basic setup: creating a cache with expiration, storing/retrieving an object, and cleanup.

import { CacheFactory } from 'cachefactory'; const cacheFactory = new CacheFactory(); let cache; if (!cacheFactory.exists('my-cache')) { cache = cacheFactory.createCache('my-cache', { deleteOnExpire: 'aggressive', recycleFreq: 60000 }); } else { cache = cacheFactory.getCache('my-cache'); } cache.put('/books/1', { title: 'BookOne', id: 1 }); const book = cache.get('/books/1'); console.log(book); cache.remove('/books/1'); cacheFactory.destroy('my-cache');

Debug

Known issues

deprecatedCacheFactory is no longer actively maintained. Last publish in 2017. Consider using lru-cache or quick-lru for newer projects.

fix

Migrate to a maintained library like lru-cache.

affects: >=3.0.0

gotchaUsing require('cachefactory') returns the module with default export? Actually, v3 is ESM-only; require will throw an error.

fix

Use import syntax or enable esModuleInterop in TypeScript and use default import.

affects: >=3.0.0

breakingVersion 3.0.0 removed support for CommonJS require. Only ES modules are supported.

fix

Update imports to ES module syntax.

affects: >=3.0.0

Errors

Common errors & fixes

ERR_REQUIRE_ESM: require() of ES Module

Trying to use require() with an ES module package.

fix

Use import syntax: import { CacheFactory } from 'cachefactory'; or enable ESM in your project.

Cannot find module 'cachefactory'

Package not installed or incorrect path.

fix

Run npm install cachefactory --save

TypeError: cacheFactory.createCache is not a function

Importing default export incorrectly (e.g., using CacheFactory from default export without new).

fix

Ensure you import { CacheFactory } from 'cachefactory' and instantiate: new CacheFactory()
